Landmark Agreement on Climate
Is Reached in Paris to Cap Warming
Climate negotiators meeting in Paris have achieved a deal
that could change the world. The Paris Agreement commits the
UN Secretary General Ban Ki-moon and other leaders
international community to capping global warming to "well below 2 degrees Celsius above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5 degrees C." To achieve that, the agreement requires the world to "reach global peaking of greenhouse gas emissions as soon as possible" and "to undertake rapid reductions thereafter, in accordance with best available science." The intention is to reduce net greenhouse gas emissions to zero in the second half of this century. "This agreement is a turning point," said Johan Rockström of the Stockholm Resilience Center.

process that repeats itself year after year as property owners clear their land of debris for farming. This year, however, saw significantly more fires than usual, and many of those fires escaped their handlers and burned uncontrollably for weeks or months. The fires produced a massive plume of carbon monoxide (CO) — a toxic gas that affects both human health and the climate — that could be detected by NASA satellites
. “The 2015 Indonesian fires produced some of the highest concentrations of carbon monoxide that we have ever seen with MOPITT,” the satellite technology that detected the gas, said Helen Worden, a scientist at the National Center for Atmospheric Research. Typically, CO concentrations in that region are roughly 100 parts per billion. Some parts of Borneo, however, saw CO levels of nearly 1,300 parts per billion in September and October.

Paris COP21: An Unexpected Move
Toward Global Target of 1.5 Degrees
It is the big surprise of the Paris talks: the growing acceptance of a call from small nations most vulnerable to climate change
for the conference to declare warming should be halted at 1.5 degrees Celsius. Even a few months ago, this seemed unimaginable. Two degrees was the only target on the table. But here it has gained momentum with more than 100 nations, including the U.S. and the EU, agreeing it should be in the final agreement. With more than a day of talks remaining, inclusion is far from a done deal. But it has strong support. A 1.5-degree target “looks much more scientifically justifiable,” said Johan Rockström, director of the Stockholm Resilience Institute.

China and the U.S., with resulting declines in emissions for both countries. The fuel looks incompatible with a world that warms by no more than two degrees C, bringing calls for its rapid phaseout as the global economy is "decarbonized." But, with or without a deal in Paris later this week, will the calls be heeded? Has the demise of King Coal been greatly exaggerated? The smart money in Paris is betting that, despite the embrace of coal by some developing countries such as India and Turkey, the dirty fossil fuel’s days are numbered. "The inevitable conclusion we can draw on the future of global thermal coal is that it has none," an energy analyst said in Paris.

What is at issue now are the rules for their implementation, including funding of pledges from poor nations, and whether a procedure can be agreed for upgrading them later to give the world a chance of meeting its two-degree Celsius temperature-rise target. To do all that in the final few days of the conference, negotiators are considering a 48-page draft text that contains numerous brackets, which denote alternative options and text yet to be agreed on. U.N. Secretary-General Ban Ki-moon said he expected the final deal to include a review of emissions targets every five years to determine how they are playing out and to allow for increasingly ambitious goals that could secure the two-degree target.

replanting forests and reviving soils. The group, which includes the World Bank and the African Union's New Partnership for Africa's Development are seeking $2 billion a year to restore 100 million hectares of Africa by 2030 — an area three times the size of Germany. The plans were announced to some 3,000 delegates attending a Global Landscapes Forum in Paris on Sunday. "We need landscape restoration for development and for climate," said Ngozi Okonjo-Iweala, a former Nigerian finance minister. Some African countries said they are already at work. Ethiopian ministers told the forum they had restored a million hectares of farm soils in the drought-hit Tigray region and elsewhere in the past 20 years, through terracing, irrigation and other activities.

published in the journal Nature Climate Change
. The flat-lining emissions trajectory is the result of China's recent sharp decline in coal burning and the global surge in renewables like wind and solar power, said Corinne Le Quéré, director of the Tyndall Centre at the University of East Anglia in Norwich, England, who led the analysis. The study estimates China's emissions have fallen by 3.9 percent this year. Le Quéré said she does not believe the world has yet hit "peak emissions." Continued rapid industrial expansion by countries such as India that still rely on coal for energy means further rises probably lie ahead, she said. But the evidence is growing that peak emissions may be closer than previously imagined.

Yards away, a meeting of financiers and bankers got under way in which a central demand was for, well, much the same thing. Something strange has happened here. The masters of the financial universe are out in force insisting that, though they may not be waving placards or chanting slogans, they are part of the solution. Free markets could deliver a zero-carbon world, they say. And Mark Carney, the governor of the Bank of England and a leading player in the global financial system, announced the creation of a task force to develop a carbon-disclosure system that could force companies to reveal how heavily their businesses are invested in fossil fuels. He said it could become standard business practice around the world — carbon footprinting for financiers.

such as emissions-pledge reviews, as the 50-page draft climate treaty
now contains four to five alternative versions of disputed points. Fabius has given negotiators until Thursday night to deliver a streamlined draft and has set a deadline of noon Saturday to come up with a close-to-final draft.

Paris COP21: Is India the Main
Stumbling Block at Climate Talks?
By some measures India has offered a lot to the Paris neogitations. Its pledge on future emissions includes perhaps the
Indian Prime Minister Narendra Modi
most ambitious renewable energy program in the world, with 175 gigawatts of green power, including 100 megawatts of solar panels, by 2022. But many nonetheless see India as the biggest single threat to curbing CO2 emissions in the next few decades. The problem is coal. The speed of India's current industrialization is so fast that, even with a huge surge in solar energy, it still plans the world's fastest rate of construction of coal-fired power stations. India's continued reliance on coal will increase its CO2 emissions by 60 per cent by 2030. And that addiction to coal is making enemies among countries that India would normally count as its friends – poor nations most at risk from climate change.

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."

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.

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

save them money, according to
research published in the journal Nature Climate Change
. Researchers developed a list of 14 strategies, all based on current technologies, that airlines could pursue to cut emissions, which account for roughly 2 to 3 percent of the total carbon dioxide added to the atmosphere each year. For example, one recommendation is to keep planes at the gate until takeoff rather than making them idle on the runway, or to use fewer engines — perhaps even electric engines — when taxiing. Emissions could also be cut significantly by reducing aircraft weight, the researchers say, such as by lowering the amount of extra fuel carried or replacing seats and brakes with ones made from lighter materials. Updating flight paths to more direct routes, adjusting altitude and speed to avoid drag-inducing turbulence, and retiring older planes would also cut costs and emissions.

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.

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.

, 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.

Global Forest Cover Estimates
Vary Widely Based on Definition, Study Says
Measurements of global forest cover can vary widely — by as much as 6 percent of the planet's land area, a swath equal in size
to China, according to research
from the University of Maryland. The reason behind the discrepancy actually lies in how different researchers and organizations define forest cover, the researchers note. Geographers have long called for the definition to be standardized, but until now, no one had quantified the scope of the variance. The largest ambiguities in forest calculations are driven by uncertainties near savannas, shrublands, mountain ridge forests, and other areas with intermediate tree cover. “It’s not technology’s fault” that forest maps are inconsistent, said lead author Joseph Sexton. But until the definitions are standardized, he said, it will be difficult to properly assess land cover or conservation measures related to climate change and biodiversity.

Opponents have argued that the genetic integrity of wild salmon could be threatened if the GM fish were to escape from contained farms into rivers and oceans. The company says, however, that the fish will be raised on land, thus making escape into the wild impossible, and that the GM salmon can be farmed more efficiently because they have a faster growth rate than conventionally farmed salmon.

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.

New Study Finds Limited and
Uneven Water Reserves Near Earth's Surface
Roughly 5.5 million cubic miles of groundwater are stored in the earth’s crust, according to
new research published in
the journal Nature Geoscience
, but the resource is distributed unevenly across the globe, as shown in this map. Combining data with models on the permeability and porosity of rocks and soils, and on water table gradients, researchers illustrated the depth of groundwater around the world. If earth's groundwater were to cover the planet's surface evenly, the scientists predicted that the pool would be approximately 600 feet deep. However, only six percent of this groundwater is usable for most purposes. This water, which is closer to the surface, is also more sensitive to climate change and human contamination. The research highlights how unevenly this resource is distributed across the globe, scientists say, as well as the need to manage water reserves in a sustainable way.

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.

Renewable Diesel Production and
Demand Growing Worldwide, Report Finds
A new type of renewable, non-petroleum-based diesel fuel is on the rise worldwide, according to the U.S. Energy Information Administration
with demand driven by mandates in multiple countries. Unlike other biofuels, renewable HEFA biofuels — the acronym stands for hydroprocessed esters and fatty acids, and the fuels are known as "renewable diesel" in the U.S. — are nearly indistinguishable from their petroleum counterparts, meaning they can serve as "drop-in" fuels, readily substituting for traditional diesel. For example, they can be used in diesel engines without the need for blending with petroleum diesel fuel. Worldwide, more than a billion gallons of HEFA fuels were produced in 2014. Ten plants worldwide now produce renewable diesel, and five additional projects are in development. Alaska Airlines, KLM, and United Airlines have demonstrated the use of HEFA biojet fuel on commercial flights since 2011.

, 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.”
