Nuclear Power Has Prevented
1.84 Million Premature Deaths, Study Says
The use of nuclear power from 1971 to 2009 prevented more than 1.8 million premature deaths
related to air pollution and 64 billion tons of greenhouse gas emissions, a new study says. Using historical production data and estimates of mortality per unit of electricity generated, scientists from NASA’s Goddard Institute for Space Studies and Columbia University calculated that replacing nuclear energy sources with fossil fuel-burning sources during that period would have caused about 1.84 million premature deaths. By midcentury, they project, nuclear power could prevent an additional 420,000 to 7 million deaths, depending on which fossil fuels it replaces, and 80 to 240 billion tons of greenhouse gas emissions. “By contrast, we assess that large-scale expansion of unconstrained natural gas use would not mitigate the climate problem and would cause far more deaths than the expansion of nuclear power,” said Pushker A. Kharecha, who, along with NASA’s James Hansen, co-authored the study published in the journal Environmental Science & Technology
. The study calculated that nuclear power plant accidents caused about 4,900 deaths during the same period.

China Poised to Launch
Much-Anticipated Carbon-Trading Project
China has revealed details of a carbon cap-and-trade pilot project that will be launched next month, a much-anticipated market attempt to rein in carbon dioxide emissions by the world’s biggest emitter. The first phase of the program, which will be implemented in the southern city of Shenzhen, will cover 638 companies
that produce 38 percent of the city’s carbon emissions, according to the city branch of the government’s National Development and Reform Commission (NDRC). The system will impose caps on the companies’ CO2 emissions and establish a market for the buying and selling of emissions permits. Eventually, the program will be expanded to include the transportation, manufacturing, and construction sectors, the Guardian
reports. By 2014, the experimental scheme will be expanded into six other designated cities and provinces, including Beijing and Shanghai. Earlier this week, the Chinese newspaper 21st Century Business Herald
reported that the NDRC is contemplating a nationwide system to control CO2 emissions by 2020.

Large Majority of Americans
Believe Global Warming Should be a Priority
Roughly 70 percent of Americans say global warming should be a priority for President Obama and Congress and 61 percent support requiring fossil fuel companies to pay a carbon tax that would be used to help reduce the national debt, according to a new survey
by the Yale Project on Climate Change Communication. In a national survey conducted in April, 87 percent of respondents said that the president and Congress should make developing clean sources of energy a priority, 68 percent favored regulating carbon dioxide as a pollutant, and 71 percent supported providing tax rebates for people who buy solar panels and energy-efficient vehicles. Seventy percent said global warming should be at least a “medium” priority, while 28 percent said it should be a low priority. The poll showed that 7 in 10 Americans support funding more research into green energy sources.

Scientist’s U.S. Road Trip
Reveals Unexpected Methane Emissions
Methane measurements collected during a scientist’s road trip across the U.S. indicate that local emissions of the potent greenhouse gas are higher than previously known in many regions
. Using a gas chromatograph mounted to the roof of a rented camper, Ira Leifer of the University of California, Santa Barbara, collected air samples from Florida to California, finding the highest methane concentrations in areas with significant refinery activity — such as Houston, Texas — and in a region of central California with oil and gas production. He found that methane concentrations exceeded the levels estimated by the U.S. Department of Energy, particularly in areas near industrial fossil fuel extraction sites. The results point to the importance of targeting these “fugitive” methane emissions in parallel with efforts to reduce CO2 emissions. Leifer's findings were published in the journal Atmospheric Environment

Glaciers on Everest Disappearing
As Temperatures Rise, Snowfall Declines
The glaciers on Mount Everest and the surrounding region have shrunk by 13 percent
in the last five decades as temperatures have risen and snowfall has declined in
that section of the Himalaya, according to a new study. Using satellite imagery and topographic maps, a team of scientists found that the majority of glaciers on Everest, the world’s tallest mountain, and in the surrounding Sagarmatha National Park are retreating at an accelerating rate. In the last 50 years, the snowline in the Everest region has shifted up by an average of 590 feet (180 meters), said Sudeep Thakuri, a Ph. D. student at the University of Milan and leader of the research team, which presented its findings at a conference in Cancún, Mexico. Because glaciers are melting faster than they are being replenished, researchers say, rock and debris that were previously hidden under snow are now exposed and absorbing heat.
Interview: Climate Pioneer’s Son
Ponders a Worrisome CO2 Milestone
Climate scientist Ralph Keeling has followed in the footsteps of his renowned father, Charles David Keeling, who in 1958 became a pioneering figure in humanity’s struggle to combat climate change when he developed an accurate method of measuring CO2 in the atmosphere and
Scripps Institution of Oceanography
tracking its increase. Today, his son is the director of the Scripps CO2 Program, which was founded by his father and this month reported that global carbon dioxide concentrations had passed an alarming milestone of 400 parts per million. In an interview with Yale Environment 360
, Ralph Keeling discusses his father’s work, reflects on the meaning of CO2 levels climbing higher than they’ve been in at least 800,000 years, and expresses hope that crossing the 400 ppm mark may play a role in awakening the public to the dangers of runaway climate change. “It feels a little bit like we’re moving into a new era,” said Keeling. “Bringing about change requires people to be aware of what’s going on.”

Project Looks to Quantify
Power Emissions Through Crowdsourcing
A team of scientists is enlisting public support to help produce a more comprehensive inventory of carbon dioxide emissions from power plants globally, urging citizens to identify power plants in their communities
with a new digital app. While data from some of the
world’s industrialized regions — including the U.S. and Europe — are already widely available, researchers at Arizona State University (ASU) say specific information on carbon emissions from most parts of the world is difficult to obtain. “It turns out that we know far less about fossil fuels than we thought we did,” Kevin Gurney, an emissions modeler at ASU and co-leader of the so-called Ventus Project, told Nature
. “We could use some help.” Using a simple Google Earth application, the technology enables users to upload exact coordinates of local power plants, and, if possible, information on the type of fuels used or the quantity of CO2 emissions. Organizers hope that the crowdsourcing initiative will fill data gaps on the world’s roughly 30,000 power plants.

U.S. Web Tool Aims to Bolster
Research on Climate and Health Links
The Obama Administration this week introduced an online tool
to improve research into the link between climate change and human health and promote innovative responses to future threats. As climate change triggers more extreme weather events and temperature shifts, it is becoming increasingly important to determine how these changes will affect respiratory illnesses, infectious diseases, allergies, and other human ailments, said Tom Armstrong, executive director of the U.S. Global Change Research Program. Writing on the department’s blog
, Armstrong said the so-called Metadata Access Tool for Climate and Health
, or MATCH, will provide an accessible portal of metadata from more than 9,000 health, environment and climate science data sets. “MATCH will help researchers and public health officials integrate the latest information from across environmental and health disciplines in order to inform more effective responses to climate and health threats,” he said.

Third Coal Export Proposal
Falls By Wayside in Pacific Northwest
A large U.S. pipeline developer has dropped plans to build a $200-million coal export facility in northern Oregon, the third major terminal proposal to be shelved or canceled in the Pacific Northwest. Officials at Houston-based Kinder Morgan say the Columbia River site could not optimally accommodate the 30 million tons of coal that were expected to run through the site annually, largely for markets in Asia. While the company said the decision had nothing to do with public opposition to transporting massive amounts of coal from the Powder River Basin in Wyoming to the coast, critics of the plan say growing protests affected the decision. “If that site didn’t meet their physical constraints, they would have known that… years ago when they proposed this,” Brett VandenHeuvel, director of the group Columbia Riverkeeper, told the Los Angeles Times
. Thousands of residents have signed petitions to block the project, citing concerns that the coal trains would cause pollution from coal dust and create traffic congestion. Three other coal export projects — two in Washington and one in Oregon — are still on the table

Declining Snow Cover Imperils
Plant and Animal Species, Study Says
Declining winter and spring snow cover in parts of the Northern Hemisphere poses a growing threat to the plant and animals species that depend on the snow to survive harsh winters
, a new study says. Writing in the journal Frontiers in Ecology and the Environment
team of scientists reports that shorter snow seasons and decreased snow depths are altering the so-called subnivium, a seasonal microenvironment beneath the snow that provides refuge for a variety of life forms, from microbes to bears. In the last four decades, snow cover in the Northern Hemisphere has declined by as much as 3.2 million square kilometers during the months of March and April. Spring melting has accelerated by nearly two weeks, and the period of maximum snow cover has shifted from February to January, the scientists say. If exposed to temperature fluctuations as a result of disappearing snow, reptiles and amphibians could emerge from winter torpor prematurely, and plant species would be subject to harmful freeze-thaw cycles.

Program Targeting Diesel
Emissions Will Be Cut by 70 Percent
A federal program that has cleaned up or removed 50,000 high-polluting diesel engines from U.S. roads is scheduled to be cut by 70 percent under President Barack Obama’s latest budget.
The program eliminated 230,000 tons of soot and smog-causing pollutants, slashed more than two million tons of carbon dioxide emissions, and saved 205 million gallons of fuel. But the program’s budget has faced steady cuts in recent years, falling from $50 million in fiscal year 2011, to $20 million in 2013, to a proposed $6 million in fiscal year 2014. The diesel cleanup program has succeeded in removing only a fraction of the 11 million dirty, pre-2006 diesel vehicles on the road. But environmentalists say that the program has been successful in helping clean the air in low-income communities that often are situated near ports, highways, and other areas with high diesel traffic.

Ocean off the U.S. Northeast
Was Warmest in 150 Years, Report Says
Sea surface temperatures along the northeastern U.S. were warmer in 2012 than during any year in the last 150 years
, a new report finds. According to the National Oceanic and Atmospheric Administration’s (NOAA) latest Ecosystem Advisory for the Northeast Shelf
, sea surface temperatures across the region — which extends from Cape Hatteras, N.C., to the Gulf of Maine — averaged 14 degrees C (57.2 degrees F) last year, significantly higher than the average temperature over the last three decades, which was 12.4 degrees C (54.3 degrees F). It was also the biggest one-year increase since records were first kept in 1854. While the data historically has been collected by ship-board instruments, NOAA now also incorporates satellite remote-sensing technology. “Changes in ocean temperatures and the timing and strength of spring and fall plankton blooms could affect the biological clocks of many marine species, which spawn at specific times of the year based on environmental cues like water temperature,” said Kevin Friedland, a NOAA scientist.

New Web Site to Track
CO2 Levels As Planet Approaches 400 PPM
As atmospheric concentrations of carbon dioxide approach the milestone of 400 parts per million (ppm), a scientist at the Scripps Institution of Oceanography has launched a Website
that will publish daily readings of CO2 concentrations, an online resource he hopes will drive home the urgent threat of rising greenhouse gas emissions. Ralph Keeling, director of the Scripps CO2 program and son of the first scientist to measure CO2 concentrations, hopes the daily tracker will attract more attention than weekly or monthly postings, providing a stark index of humanity's effect on the global climate. “I hope that many people out there in decades to come will say, ‘Gosh, I will remember when it crossed 400,’” Keeling told ClimateWire
. The measurements will come from the Mauna Loa observatory in Hawaii. Keeling’s father, Charles David Keeling, first started collecting CO2 concentrations in the 1950s from the same observatory, when few believed that carbon dioxide concentrations were in fact rising. His ongoing recording of CO2 concentrations came to be known as the “Keeling Curve
.” As of April 22, CO2 concentrations had reached 398.36 ppm, according to the site, well above pre-industrial concentrations of about 280 ppm.

Reducing Short-Lived Pollutants
Could Slow Sea Level Rise, Study Says
Reducing the emissions of four critical pollutants in the coming decades could at least temporarily slow the rate of global warming and reduce projected sea level rise by as much as 50 percent
, according to a new study. Building on previous research that found that reducing the emissions of four short-lived pollutants — tropospheric ozone, hydrofluorocarbons, black carbon, and methane — could slow the rate of global warming by 50 percent, the new study projects that sea-level rise could, in turn, be reduced by 24 to 50 percent by 2100, depending on the level of emissions cuts. Unlike carbon dioxide, which persists in the atmosphere for centuries, these four pollutants remain in the atmosphere anywhere from a week to a decade, so altering their atmospheric concentrations can have a more immediate effect on the global climate, scientists say. “Society can significantly reduce the threat to coastal cities if it moves quickly on a handful of pollutants,” said Aixue Hu, a researcher at the National Center for Atmospheric Research (NCAR) and lead author of the study published in the journal Nature Climate Change

Outdated Management, Drought
Threaten Colorado River, Report Says
Drought, mismanagement, and over-exploitation of its waters have made the Colorado River — the lifeblood of the arid Southwest and drinking water source for 36 million people — among the most vulnerable rivers in
the U.S., according to the group American Rivers. In its annual report on “America’s Most Endangered Rivers
,” the organization placed the 1,400-mile Colorado at the top of the list of threatened rivers, saying the iconic river “is so dammed, diverted, and drained that it dries to a trickle before reaching the sea.” Proposals to remove more than 300,000 acre-feet of new water from the river and its tributaries, coupled with a projected reduction in its flow of 10 to 30 percent because of global warming, will add further stress to the Colorado system
. According to the report, outdated water management systems also threaten the Flint River in Georgia, the San Saba River in Texas, and the Little Plover River in Wisconsin. In the U.S. Southeast, storage ponds for coal ash pose a threat to the Catawba River, a major source of drinking water for parts of North Carolina and South Carolina.
Interview: Using Citizen Power
To Fund a U.S. Solar Revolution
Billy Parish is the president of Mosaic
, an Internet “crowdfunding” service that lets individual investors put their money into commercial solar projects and earn a rate of return that
currently beats anything offered by a bank. This month, California regulators authorized Mosaic to offer up to $100 million in loans for solar projects. Its first loan under that authorization, $157,750 to install a 114-kilowatt array on the Ronald McDonald House in San Diego, was funded within six hours by 171 investors. Parish, 31, a co-founder of the Energy Action Coalition
, decided after the failure of the 2009 climate talks in Copenhagen that the best way to drive a clean energy transition was to dive into the renewable energy business. In an interview with Yale Environment 360
, Parish talks about why his generation has pursued environmental goals through entrepreneurship, how crowdfunding can fuel the solar revolution, and how he discovered “that sweet spot where making money and doing good overlap.” Read the interview

Arctic Air Pressure System
Causes Unusual March Temperatures
A pronounced shift in Arctic air pressure systems has triggered unusually cold temperatures across North America, Europe, and northern Asia, while allowing a
flood of warmer air into Greenland and northeastern Canada, according to NASA. In recent weeks, the so-called Arctic Oscillation (AO) index — which tracks the relative pressure differential between the Arctic and mid-latitudes — dropped to the fifth-lowest reading ever recorded, NASA scientists said
. When the AO reaches this “negative” phase, scientists say, the pressure gradient between the Arctic and mid-latitudes weakens, allowing Arctic air to stream south. This NASA graphic
depicts unusual land surface temperatures across the Northern Hemisphere, with Europe, Russia, and the U.S. experiencing temperatures as high as 5 to 15 degrees C below normal, while temperatures in Greenland were as high as 15 degrees C above normal. Britain recorded its fourth-coldest March since 1962, Germany experienced its coldest March since 1883, and Moscow had its coldest March since the 1950s.

Genetic Discovery May Allow
Lettuce Growth Even in Hot Temperatures
A team of scientists has identified the specific gene in lettuce that causes the plant’s seeds to stop germinating in warm temperatures, a discovery they say could allow production of the food crop year-round even in the planet’s hotter regions. Writing in the journal The Plant Cell
, the researchers say they identified a chromosome in the wild ancestor of commercial lettuce varieties that enabled seeds to germinate even in warm temperatures. When the chromosome was crossed with commercial varieties of lettuce, they too were able to germinate at warmer temperatures
. After further testing, the scientists found the specific gene that governs a plant hormone known as abscisic acid — which inhibits seed germination in most lettuce plants when exposed to moisture at warm temperatures — and were able to “silence” the mechanism. Because this mechanism occurs in many plant species, the results suggest similar modifications can be made in the growth of other crops, said Kent Bradford, of the University of California Davis, who is one of the study’s authors

New Carbon Storage Method
Reduces Earthquake Risk, Study Says
A team of researchers says it has demonstrated a method of underground carbon storage that reduces the risk of triggering earthquakes
, a safety concern cited by some scientists about the emerging field of carbon capture and sequestration. While often cited as a potentially key option in reducing atmospheric levels of carbon dioxide, earlier studies
have suggested that the use of carbon sequestration technologies in some rock formations can result in leaks that ultimately cause minor tremors. But in a new study, published in the journal Geophysical Research Letters
, Yale University researchers say that storing carbon in a common type of volcanic rock, known as reactive mafic rock, offers a far safer alternative. According to their findings, injecting carbon into the mafic rock causes a chemical reaction that generates carbon minerals, creating a so-called “mineral-trapping” phenomenon that reduces fluid pressure and distributes the stress load, which in turn minimizes seismic risks.

Obama Unveils New Actions
To Combat Climate Change in Second Term
Making good on his promise to fight climate change more aggressively in his second term, President Obama is unveiling two major initiatives to reduce the U.S.’s reliance on fossil fuels, including a new $2 billion Energy Security Trust to fund the next generation of green vehicles, as well as new reviews of federal projects to assess their climate impacts. During an appearance at Argonne National Laboratory, Obama unveiled details of the proposed energy trust, which would shift $2 billion in royalties from oil and gas operations on federal lands
into research into vehicles powered by renewable energy sources. An administration official said the policy will keep the U.S. at the forefront of the emerging green technology sector and will help the nation wean itself off fossil fuels. Obama is also expected to expand a Nixon-era law to require federal agencies to assess the climate effects of large projects
, including pipelines and highways.

type of plant growth that just a few decades ago occurred hundreds of miles to the south, according to a new study. In a comprehensive analysis of ground and satellite-based data, a team of scientists found that across a region covering more than 9 million square kilometers — roughly equal to the size of the U.S. — vegetation is growing more vigorously and spreading north. The study, published in the journal Nature Climate Change
, said that since the early 1980s, the kind of vegetation that was once found at 57 degrees north — typified by tall shrubs and trees — is now spreading into former regions of tundra as far as 64 degrees north. The paper said that 17 climate model simulations suggested that bv the end of this century rising temperatures could lead to northward shifts of vegetation of more than 20 degrees latitude compared with the period 1951 to 1980.

Atmospheric CO2 Concentration
Shows Second-Largest Annual Increase
The amount of carbon dioxide in the atmosphere increased by 2.67 parts per million in 2012
, marking the second-biggest jump since levels were first recorded in 1959 and decreasing the chances that the planet will
avoid a dangerous temperature increase of 3.6 degrees F (2 C) or higher, U.S. scientists say. The new data, collected in Mauna Loa, Hawaii, suggests that levels of heat-trapping CO2 are now just under 395 parts per million (ppm) and could hit 400 ppm within two years, according to the National Oceanic and Atmospheric Administration (NOAA). The one-year increase was second only to 1998, when CO2 concentrations jumped by 2.84 parts per million; pre-industrial atmospheric concentrations of CO2 were 280 ppm. Pieter Tans, a senior scientist at NOAA's Climate Monitoring and Diagnostics Laboratory, attributed the latest spike to an increase in fossil fuel burning globally, particularly in China. “It’s just a testament to human influence being dominant,” he told the Associated Press.

U.S. Educational Standards
To Urge Teaching About Climate Change
A new set of U.S. educational standards that is expected to be released this month will recommend that global warming be included in the science curriculum for all U.S. public schools. The Next Generation Science Standards
, which are being developed by a coalition that includes the National Research Council and 26 individual U.S. states, will recommend that teachers introduce evidence of human-caused climate change in all science classes, beginning in elementary school, according to Inside Climate News
. According to the standards, by eighth grade all students should understand that “human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature.” With an additional 15 states indicating that they will also adopt the standards, the report says, the U.S.’s biggest educational publishing companies are already expected to incorporate the new standards into their textbooks and other teaching materials.

Earth Unlikely to Face
An Ecological Tipping Point, Study Says
A team of international scientists has rejected the idea that the planet could face a sudden and irreversible ecological shift as a result of largely human-driven pressures, suggesting that such global transformations are more likely to occur over a long period of time. While earlier studies have warned that ecological pressures — including climate change, biodiversity loss, and over-exploitation of resources — could drive the planet toward a dangerous “tipping point,” the new paper says the ecosystems of different continents are not sufficiently interconnected for such a global shift to occur
. And while as much as 80 percent of the biosphere includes ecosystems that have been affected by human activities, major ecological shifts driven by these human pressures “depend on local circumstances and will therefore differ between localities,” said Erle Ellis, a scientist at the University of Maryland, Baltimore County and co-author of the paper, published in the journal Trends in Ecology and Evolution

Major U.S. Utility Will Close
Three Coal-Burning Plants in Midwest
One of the U.S.’s largest electric utilities has agreed to close three coal-fired power plants
in the Midwest, the latest sign of how the U.S.'s electricity supply is shifting away from coal to natural gas and renewable energy. American Electric Power (AEP) will shut down the three plants in Indiana, Ohio and Kentucky by 2015 — retiring a total of 2,011 megawatts of coal-burning capacity — and replace some of the power generation with wind and solar investments in Indiana and Michigan. According to the agreement, which settles a lawsuit originally filed in 1999 over the environmental costs of pollution that drifts east from the plants, the Ohio-based company will also spend $5 billion to install pollution-control technologies at its aging coal-burning plants in the eastern U.S. and cut its annual sulfur dioxide emissions from 828,000 tons to 174,000 tons within 12 years. With the latest shut-downs, utilities have now closed or announced the closing of 142 coal-burning plants since 2010.

Labor Capacity To Fall as World
Gets Warmer, More Humid, U.S. Study Says
Increasingly warm and humid conditions that are predicted in the coming decades could slash worker productivity 10 percent worldwide
by mid-century and could eliminate worker capacity altogether in some regions during the hottest months, a new U.S. study predicts. In an analysis of labor capacity based on existing military and industrial heat stress standards, researchers from the National Oceanic and Atmospheric Administration (NOAA) found that the amount of work that people can do in some regions has already dropped by 10 percent over the last six decades and that the lost labor capacity could double by 2050 based on global warming projections. According to their analysis, published in the journal Nature Climate Change
, a temperature increase of 6 degrees C (11 degrees F) would “eliminate all labor capacity in the hottest months in many areas,” including the U.S.’s lower Mississippi Valley. “This planet will start experiencing heat stress that’s unlike anything experienced today,” Ronald Stouffer, co-author of the study, told Reuters
. According to the study, temperature increases must be limited to less than 3 degrees C (5 F) to maintain labor capacity in all areas during the hottest months.

A 1.5 C Temperature Rise Could
Release Greenhouse Gases in Permafrost
A global temperature increase of 1.5 degrees Celsius could unleash more than 1,000 gigatons of carbon and methane
currently trapped beneath Siberian permafrost and accelerate global climate change, a new study says. In a study conducted in a frozen cave in Siberia, researchers analyzed stalactites and stalagmites which, since they form only when rainwater and snowmelt drip into the caves, provide a glimpse into 500,000 years of changing permafrost conditions. According to their findings, records of an especially warm period 400,000 years ago suggest that a 1.5-degree increase compared to current temperatures would trigger the thawing of permafrost far north of its existing southern boundary. And since permafrost covers 24 percent of the exposed land surface in the Northern Hemisphere, significant thawing could release huge amounts of methane and carbon dioxide, said Anton Vaks, a scientist at Oxford University and lead researcher on the study, published in Science Express
. In addition to the effects the loss of permafrost could have on climate, it could have major regional implications, affecting roads, railways, and natural gas facilities built on the frozen landscape.

Two New Polls Show Strong
Support for Obama Action on Climate
Roughly two-thirds of the American people support President Obama taking significant action on climate change
, according to two polls released the day after Obama’s State of the Union address. A poll for the League of Conservation voters showed that 65 percent of Americans want Obama to take “significant steps”
to address climate change, including 89 percent of Democrats, 62 percent of Independents, and 38 percent of Republicans. The survey said that most Americans view climate change as a tangible threat, with 61 percent saying climate change is already affecting them or will affect them sometime in their lives. A second poll, conducted for the Natural Resources Defense Council, found that 65 percent of Americans see climate change as a serious problem and that 62 percent agreed with Obama’s call for action. Obama told Congress that if it does not pass legislation to reduce CO2 emission, he will step up efforts to deal with the problem using executive actions. Despite these poll results, another recent survey showed that Americans rank climate change last on a list of 21 problems facing the U.S.
Interview: A Conservative Who
Believes Climate Change is Real
Republican Congressman Bob Inglis lost his 2010 re-election bid after telling a campaign audience he believed in human-caused climate change.
Since then, he has served as executive director of the Energy and Enterprise Initiative, which seeks to convince conservatives that climate change is real and that free enterprise principles hold the keys for dealing with it. In an interview with Yale Environment 360
, Inglis talks about his own evolution from being a climate change denier; why he favors a carbon tax and the end of all fuel subsidies; why conservatives have been so reluctant to acknowledge that climate change is real; and why his group is focusing its efforts on college Republicans. “We’re trying to convince conservatives that they are more important to this than they ever imagined,” he says, “because they have the answer, which is free enterprise. And it’s a better answer than a regulatory regime.” Read the interview

Norwegian Retrofit Seeks
To Create ‘Energy-Positive’ Office Buildings
Two office buildings in Norway are being retrofitted so they will generate more power than they use
when the project is completed next year. The three- and four-story buildings, in the town of Sandvika, near Oslo, will generate geothermal and solar energy on site, making the buildings “energy positive,” according to the project's backers. The retrofit will use a heat-retaining black façade, top-quality insulation to reduce energy use by up to 90 percent, and an interior design that will allow air to circulate without fans. “We believe this is the first time in the world that a normal office block is being renovated to such strict standards,” Svein Brandtzaeg, chief executive of Norsk Hydro, one of the project’s partners, told Reuters. According to the UN Environment Programme, the building industry has the greatest potential of any economic sector for large cuts in greenhouse gas emissions.
