transforming the chances of slowing global warming. President Barack Obama might wish for a deal here at U.N. climate negotiations in Paris to be his own crowning legacy. But the truth is that this is China's ball. Nobody personifies the transformation better than the head of the Chinese climate delegation for the past nine years, Xie Zhenhua. He spent years pretending climate change was a developing-world problem that the rich nations had to sort out, and he was widely blamed for scuppering the 2009 Copenhagen climate negotiations. But here in Paris he is quietly confident a deal is about to be done that will be in China's and the world's interests. "China is entering a new normal of energy and resource conservation,” he said. "We can seek a different way [through] ecologically driven wealth generation."

A Combination of Carrots and Sticks
Forests must be saved and restored if the world community hopes to slow global warming. That's a given at the Paris climate

conference. But how? It's a tough issue for many environment ministers, who know that back home their agriculture, mining, and even forestry ministers have other plans for forest lands. In nations such as Peru and Indonesia, the gap between aspirations for slowing deforestation and the reality on the ground is huge. How to close that gap is a major topic of discussion in Paris, with countries, business groups, and conservationists proposing a combination of carrots and sticks to spur reform. And advocates say that returning many forests to indigenous groups is a key part of any solution.

Paris COP21: For the Poorest
Nations, Questions of Compensation
In a series of side events on the first day of the Paris climate conference, U.N. Secretary-General Ban Ki-moon launched the
Initiative on Resilience, a program designed to help the world’s poorest countries, which are especially vulnerable to the ravages of global warming. Finance to help developing nations adapt to climate change is potentially the dealbreaker in Paris. Developing nations expect a Green Climate Fund, which would cover adaptation and the cost of moderating their greenhouse gas emissions, to contain $100 billion a year by 2020. If the money is not on the table, they may ditch their promises on emissions — and scupper the deal. Germany, France, and other developed nations promised help in Paris. But the president of Angola, chairing a group of 48 African nations vulnerable to climate change, said $5 billion of such projects were already on hold for want of cash.

of greenhouse gases and vowed that the U.S. would take a leading role in fighting climate change, which he called the central challenge of the 21st century. “The United States of America not only recognizes our role in creating this problem, we embrace our responsibility to do something about it,” Obama said at the opening of United Nations climate talks. He vowed that the U.S. and other developed nations would provide aid for renewable energy development and climate adaptation to developing nations, which he said had “contributed little to climate change but will be the first to feel its most destructive effects.” Chinese President Xi Jinping said that his country would meet its goal of hitting peak emissions by 2030
, with steady declines thereafter.

increased energy emissions despite advances in efficiency and growing use of less carbon-intensive fuels, such as natural gas. The transportation sector and residential and commercial buildings largely drove the increase, the U.S. Energy Information Administration
reports. Lower fuel prices and an improving economy led to more consumption of gasoline and other fuels, the EIA says, which more than offset gains in vehicle fuel economy. Emissions from commercial and residential buildings also rose last year. While residential energy use is mainly driven by weather on a year-to-year basis — the first quarter of 2014 was particularly cold in many regions — both weather and economic gains led to more energy consumption in commercial buildings, the report says. Looking at energy emissions by another measure, the U.S. made better progress, as CO2 emissions per unit of gross domestic product declined.

In Major Shift, Alberta
Adopts New Plans to Fight Climate Change
In a sharp reversal from the previous government, Alberta’s recently elected premier has announced a host of new climate measures
, including a tax on carbon, the phase-out of coal emissions by 2030, a transition to
renewable energy sources, and CO2 emissions limits on the province’s massive tar sands industry. Premier Rachel Notley said Sunday that the province will adopt an economy-wide carbon tax of 20 Canadian dollars in 2017, increasing to 30 dollars in 2018. She vowed that two-thirds of the electricity now produced by coal-fired power plants will be replaced with renewable energy. And she said Alberta will impose a carbon emissions limit on the oil sands industry of 100 megatons; the industry currently generates 70 megatons of carbon annually. “This is the day we step up, at long last, to one of the world’s biggest problems: the pollution that is causing climate change," Notley said.
Interview: Why Brazil’s Pledges On
Carbon Emissions Are Not Enough
In recent years, Brazil has been widely praised for reducing deforestation in the Amazon by 75 percent from 2005 to 2014.
Maria Fernanda Gebara
But analysts are now taking a closer look at Brazil’s pledges to cut deforestation and greenhouse gas emissions, with some saying there is less there than meets the eye. One of the more outspoken critics of the country’s CO2-reduction policies is Brazilian political scientist Maria Fernanda Gebara. In an interview with Yale Environment 360
, Gebara, a research associate in the Department for International Development at the London School of Economics, says Brazil’s policies will do little more than stabilize emissions for the next 15 years, will fail to clamp down on illegal logging, and will continue the nation’s dismal record of developing solar and wind power.

Icelandic Ice Cap Gains Mass for
First Time in Two Decades, Researchers Say
An Icelandic ice cap known as Hofsjökull, shown in this NASA satellite image, has gained mass for the first time since 1993,
Iceland's Hofsjökull ice cap
measurements taken last month. All ice caps in Iceland had been retreating rapidly and losing volume since 1995, due to decreasing precipitation and rising temperatures. Hofsjökull’s resurgence this year is the result of abundant winter precipitation and cooler than normal summer temperatures, explained Thorsteinn Thorsteinsson, a glaciologist at the Icelandic Meteorologial Office. Last winter, snowfall in the region of the ice cap was 25 to 60 percent thicker than the 1995-2014 average. Cool northerly winds slowed Hofsjökull’s summer melt rate, contributing to the positive measurements obtained last month.

warming, according to a study published in the journal Global Environmental Change
. The report found that Tucson, Arizona, and Raleigh, North Carolina, are in the middle-to-early stages of planning, while Tampa, Florida — which is at the highest risk for hurricanes in the U.S. and is located very near sea level — largely dismisses climate change and has done little to plan for it. The study is the first to look at societal factors, such as a city's political environment, and how those factors affect action on climate change. Interviews with 65 local policymakers in each of the six cities revealed three factors that play a role in how well city planners prepare for climate change: the risk of extreme weather in a given area, public acceptance of climate change, and how aggressively a city's residents engage in public policy.

with climate change, according to a study published in Scientific Reports
by University of Adelaide researchers. In large-tank laboratory experiments with Port Jackson sharks — a bottom-feeding variety that primarily relies on smell to find food — the researchers found that the combination of warmer water and high CO2 increased the sharks' energy requirements and reduced their metabolic efficiency. Elevated CO2 levels also dulled the sharks' sense of smell to the point that they were unable to locate prey — a finding confirmed in previous CO2/olfaction studies. Together, these effects led to dramatic reductions in the sharks' growth rates. "With a reduced ability to hunt, sharks will no longer be able to exert the same top-down control over the marine food webs, which is essential for maintaining healthy ocean ecosystems," said lead researcher Ivan Nagelkerken.

. Researchers identified 97 basins with at least a two-thirds chance of declining water supplies. Nearly 1.45 billion people rely on snowpack in just 32 of those basins for a substantial proportion of their water. Among them are the basins of northern and central California, where much of U.S. produce is grown; the basins of the Colorado and Rio Grande rivers, which serve much of the American West and northern Mexico; the Atlas basin of Morocco; the Ebro-Duero basin, which feeds water to Portugal and much of Spain and southern France; and the volatile Shatt al Arab basin, which channels meltwater from the Zagros Mountains to Iraq, Syria, eastern Turkey, northern Saudi Arabia, and Iran.

, a new tool launched today by a broad partnership including the World Resources Institute (WRI), is the first online, interactive platform for mapping lands managed by native communities. It was created to fill a critical gap in indigenous and community rights and make clear that these lands are not vacant, idle, or available to outsiders for exploitative development such as mining, palm oil plantations, or timber concessions. But Abdon Nababan, secretary general of the Indonesia's Indigenous Peoples' Alliance, cautioned that “these maps do us no good unless they become public knowledge and indigenous rights are recognized by all who have ambitions to grab our lands.”

above pre-industrial levels. That is halfway to the 2 degrees C temperature increase threshold that scientists say could dangerously destabilize the planet’s climate system. The Met office reported that from January to September this year, global temperatures hit 1.02 degrees C above pre-industrial averages and that temperatures for the full year are virtually certain to be above the 1 C level. Meanwhile, the World Meteorological Association (WMO) reported that atmospheric concentrations of CO2 in 2014 averaged 397.7 parts per million
and that average 2015 concentrations could surpass the 400 ppm mark. “We are moving into uncharted territory at a frightening speed,” WMO Secretary General Michel Jarraud said.

Obama Rejects Keystone XL
Pipeline, Ending a Seven-Year Battle
President Barack Obama has rejected a Canadian company’s request
to build the Keystone XL Pipeline, which would have carried 800,000 barrels of oil a day from Alberta’s tar sands to refineries on the U.S. Gulf Coast. The decision is a major victory for climate and conservation groups and burnishes Obama’s legacy in the battle to slow global warming. Obama’s announcement, made after a seven-year review by the U.S. State Department and other agencies, comes just weeks ahead of key United Nations climate talks in Paris. In remarks at the White House, Obama said that the economic benefits of building the pipeline were outweighed by the high environmental costs of helping move to market tar sands crude, whose production is among the most carbon-polluting on the planet. “The pipeline would not make a meaningful long-term contribution to our economy,’’ Mr. Obama said in remarks at the White House.

Pope Francis Has Swayed
U.S. Public Opinion on Global Warming
A sizable percentage of Americans, and an even larger number of U.S. Catholics, say that Pope Francis’s teachings on climate change have influenced their views on the issue. A survey by the Yale Project on Climate Change Communication
showed that 17 percent of Americans and 35 percent of Catholics say that their views on global warming have been swayed by the Pope’s messages of concern about climate change, delivered in an encyclical and in a September visit to the U.S. The researchers polled a sampling of Americans months before the pope’s encyclical and after. Those surveys showed the percentage of Americans worried about global warming rose from 51 percent in March to 59 percent in October, and that concern among U.S. Catholics grew from 53 percent to 64 percent in that period. The percentage of those who believe climate change will harm people here and abroad also grew modestly, as did the number of people who consider climate change a moral and social fairness issue.

New York State Warns
To Prepare for up to 6 Feet of Sea Level Rise
New York State is telling developers and homeowners in New York City and coastal towns that they should prepare for up to 75 inches of sea level rise
by 2100. The sea level rise projections, based on recent scientific studies by NASA and Columbia University, are part of the New York Community Risk and Resiliency Act passed after the devastation caused by Hurricane Sandy in 2012. The state says it is creating new sea level rise regulations
requiring coastal planners, developers, and builders to expect seas that could rise up to six feet and to build more resilient homes and other structures. New York officials said 500,000 people live in areas that lie less than six feet above the mean high tide line in the state. The studies took into account increased melting of ice sheets and glaciers in Greenland and Antarctica.

Global Warming Could Be
Limited To 3 Degrees C With Current Pledges
National climate pledges submitted so far by 155 countries — responsible for around 90 percent of global greenhouse gas emissions — could limit the planet's long-term temperature increase to around 3 degrees Celsius
, according to an assessment by the European Commission Joint Research Center (JRC). The climate pledges, submitted to the U.N. Framework Convention on Climate Change ahead of December's climate negotiations in Paris, are officially known as Intended Nationally Determined Contributions, or INDCs. Analysis of unconditional INDCs concludes that, if fully implemented, they could set global emissions growth at around 17 percent above 2010 levels by 2030. Combining unconditional and conditional INDCs — those that would rely on such mechanisms as international climate financial support — JRC found that global carbon emissions could peak shortly before 2030 at 12 percent above 2010 levels, then decline enough to hold temperature increases to 3 degrees C.

The study showed that permafrost is highly biodegradable, with the carbon in the thawing soils rapidly being consumed by single-celled organisms. Those organisms then release carbon into the atmosphere. The study, published in the Proceedings of the National Academy of Sciences
, documented some of the fastest permafrost decomposition rates ever recorded. In effect, the researchers said, thawing means that permafrost — currently isolated from the carbon cycle
— has the potential to become a major source of carbon emissions.

Three-Fourths of Americans
Now Say that Climate Change is Occurring
It might be Pope Francis’ forceful stance on global warming, or increasing outbreaks of wild weather, droughts, and fires.
Americans who believe climate change is occurring
But whatever the cause, 76 percent of those polled in the U.S.
say that climate change is occurring, according to a poll from the University of Texas (UT). That is a 12-percent increase from March 2012, when only 65 percent of respondents said they believed in climate change. In that same period, the number of people saying that global warming is not occurring has fallen from 22 percent to 14 percent, according to the poll. All the recent publicity about climate change even seems to have been persuasive to Republicans, who traditionally have been more skeptical that climate change is taking place. The UT poll showed that the percentage of Republicans who say climate change is happening has risen from 47 percent in March of this year to 59 percent in September.

Oil and Coal Companies
Say They Back CO2 Cuts, Climate Talks
Ten major oil companies, mainly from Europe, on Friday acknowledged their industry’s role in climate change and said they agreed with United Nations goals to limit temperature increases
to 3.6 F. Their statement follows a similar declaration
on Wednesday by 14 major companies closely tied with the fossil fuel industry, including coal giants BHP Billiton and Rio Tinto, as well as Royal Dutch Shell, BP, and the world’s largest cement maker, LafargeHolcim. The Friday statement by European oil company executives acknowledged that the “existing trend of the world’s net global greenhouse gas emissions is not consistent” with UN climate targets. But the companies did not commit to specific production cuts or supporting a price on carbon. With UN climate talks opening in Paris in December, the statements by both groups are part of public relations efforts to demonstrate that oil and coal companies are willing to join in the fight to slow global warming.

Gates Calls Divestment
A `False Solution’ to Global Warming
Bill Gates, the founder of Microsoft and co-chair of the Bill and Melinda Gates Foundation, has called the fossil fuel divestment campaign a “false solution”
to climate change and says the best way to decarbonize the global economy is by developing revolutionary renewable energy technologies. “We need an energy miracle,” Gates told The Atlantic magazine.
“That may make it seem too daunting to people, but miracles in science are happening all the time.” Gates said he is pledging $2 billion of his foundation’s endowment to research and develop alternative energy technologies. He criticized the divestment movement
for “using up (campaigners’) idealism and energy on something that won’t emit less carbon.” The Gates Foundation, the world’s largest charitable organization, has $1.4 billion invested in fossil fuel companies, and activists have been calling on Gates to sell those holdings.

Toyota Vows to Eliminate
Nearly All of Its Gasoline Cars by 2050
The global automobile giant, Toyota, has announced plans to steadily phase out production of gasoline-powered cars
and to slash emissions from its fleet by 90 percent by 2050. Speaking in Tokyo, Toyota executives vowed to work with government officials and other companies to replace internal combustion cars with hydrogen fuel cell vehicles and hybrids. “You may think 35 years is a long time, but for an automaker to envision all combustion engines as gone is pretty extraordinary,” said a senior Toyota executive. The company said that by 2020 annual sales of its hybrid vehicles will reach 1.5 million and sales of fuel cell vehicles will hit 30,000 — 10 times the projected figure for 2017. Meanwhile, Volkswagen, shaken by scandal over falsifying emissions data on its diesel cars, announced it will increasingly shift production
to hybrid and electric vehicles.

Antarctic Ice Shelves Face
Major Threat If CO2 Emissions Keep Rising
A new study says that many of Antarctica’s floating ice shelves — which play a key role in holding back vast amounts of land-based ice — could become highly unstable
later this century if greenhouse gas emissions are not sharply reduced. An international team of researchers, reporting in Nature Geoscience
, said that surface melting of Antarctica’s ice shelves could reach the point where many could disintegrate. Such surface melting has already led to the collapse of numerous ice shelves along the rapidly warming Antarctic Peninsula. The study said that surface melting of the continent’s ice sheets would double by 2050
under both intermediate- and high-emissions scenarios. After that, the fate of the ice shelves diverges sharply depending on emissions levels, with a high-emissions scenario leading to surface melting equaling or exceeding intensities associated with ice shelf collapse. Loss of the ice shelves could lead to major increases in sea level as inland glaciers flow to the sea, scientists say.

New Head of IPCC
Calls For Shift from Science to Solutions
The new chairman of the Intergovernmental Panel on Climate Change says it’s time for the global scientific body to shift from documenting the impacts of climate change to finding solutions to global warming.
Hoesung Lee, a South Korean economist who was chosen by the IPCC last week to replace former chairman Rajendra Pachauri, told the Guardian that the window to begin slashing greenhouse gas emissions is “closing very rapidly” and said that the IPCC must help spur a move toward the widespread adoption of renewable energy technologies. He said that while the IPCC, which periodically issues voluminous scientific reports on climate change, had been doing a “fantastic job” of identifying the problem, “I believe the next cycle of the IPCC should be more focused on opportunities and solutions.” Lee said that placing a global price on carbon would be “the most important building block” for reducing CO2 emissions to zero by 2100.

leased by foreign entities for agricultural use during the last 15 years, according to a report
by the Worldwatch Institute. An additional 58,000 square miles are under negotiation, the report found. “Land grabbing,” a term for the purchase or lease of agricultural land by foreign interests, has emerged as a threat to food security in several nations. Globally, over half of this land is in Africa, especially in water-rich countries like the Congo. The largest area acquired in a single country is in Papua New Guinea, with nearly 15,500 square miles (over 8 percent of the nation’s total land cover) sold or leased to foreign entities. Foreign purchase of land in developing countries has surged since 2005 in response to rising food prices and growing biofuel demand in the U.S. and the European Union, as well as droughts in the U.S., Argentina, and Australia. “Essentially no additional suitable [agricultural] land remains in a belt around much of the middle of the planet,” writes Gary Gardner, a contributing author to the report.

Africa Can Increase Renewable
Energy Use Four-Fold by 2030, Study Finds
The African continent could generate nearly a quarter of its energy needs from renewable sources by 2030, according to a report
Solar PV minigrids serving 30 villages in Mali
by the International Renewable Energy Agency
(IRENA). The report identified potential renewable energy sources — including solar, biomass, hydropower, and wind resources — equivalent to more than 375 million tons of coal. While half of energy use in Africa today involves traditional biomass consumption, the report estimated that a shift to renewable-energy cooking solutions would reduce traditional cook stove usage and the resulting health complications from poor indoor air quality, leading to savings of $20 to 30 billion annually by 2030. In the African power sector, the share of renewable sources could increase to 50 percent by 2030, reducing carbon dioxide emissions by more than 340 million tons, the IRENA report says.
