The key global goal of limiting global warming to 2 degrees Celsius is already beyond reach as negotiators begin planning a 2015 climate treaty, experts say. "There is nothing that can be agreed in 2015 that would be consistent with the 2 degrees," said former United Nations climate chief Yvo de Boer. "The only way that a 2015 agreement can achieve a 2-degree goal is to shut down the whole global economy

The citizens of four major European countries think the impacts of climate change such as severe floods and storms are already affecting them, according to a major new polling study. The research dispels the idea that global warming is widely seen as a future problem, and also shows strong support for action to tackle global warming, including subsidies for clean energy and big financial penalties for nations that refuse to be part of the international climate deal signed in Paris in 2015 - as US president Donald Trump has threatened.

Global warming will have a variety of effects on our planet, yet it may also directly impact our human biology, research suggests. Specifically, climate change could alter the proportion of male and female newborns, with more boys born in places where temperatures rise and fewer boys born in places with other environmental changes, such as drought or wildfire caused by global warming.

Worldwide levels of carbon dioxide - the gas scientists say is most responsible for global warming - reached a significant milestone for the month of March, the National Oceanic and Atmospheric Administration said Wednesday. The global monthly average for carbon dioxide hit 400.83 parts per million in March, the first time the average surpassed 400 ppm for an entire month since such measurements began in the late 1950s, NOAA said.

Global carbon dioxide levels averaged 400.83 parts per million in March, marking the first time that atmospheric carbon has remained above the 400 ppm threshold for an entire month, according to the National Oceanic and Atmospheric Administration. "It's both disturbing and daunting," said NOAA chief greenhouse gas scientist Pieter Tans. 

Sea level rise is caused primarily by two factors related to global warming: the added water from melting land ice and the expansion of sea water as it warms. The first chart tracks the change in sea level since 1993 as observed by satellites. The second chart, derived from coastal tide gauge data, shows how much sea level changed from about 1870 to 2000.

A slowdown in the pace of global warming in the early 2000s was likely due to changing aerosol emissions -- and future changes could have the opposite effect and accelerate climate change, researchers say.

Recent studies have shown, for example that the loss of important predators - from wolves in boreal forests to sharks in seagrass meadows - can lead to growing populations of terrestrial and marine herbivores, whose widespread grazing reduces the ability of ecosystems to absorb carbon.

America's energy economy is growing cleaner, but the country's embrace of gas and renewables is driving conventional energy giants to ship fossil fuels to buyers overseas. That might limit the climate impact of the greener U.S. energy economy, experts say. "The Obama administration wants to be seen as a climate leader, but there is no source of fossil fuel that it is prepared to leave in the ground," said Lorne Stockman of Oil Change International

The ability of Europe's aging forests to absorb carbon dioxide is heading towards saturation point, threatening one of the continent's main defenses against global warming, a study showed on Sunday.

The best climate scientists in the world are telling us that extreme weather events like hurricanes are likely to become more powerful.  When you combine stronger storms with rising seas, that's a recipe for more devastating floods.

Eight Latin American countries on Sunday announced an initiative to restore 20 million hectares of degraded forest and farmland, seeking to use this land to store carbon in natural vegetation and cut emissions that cause global warming.

BP's shareholders overwhelmingly supported a resolution on Thursday that would force the company to disclose some of its climate change-related risks. The shareholder vote was extraordinarily lopsided, with about 98% of shareholders approving the resolution, which had the backing of BP's chairman, Carl-Henric Svanberg. The embrace of the climate change resolution is being called a watershed event in the history of climate-related shareholder resolutions, which investors large and small have been pursuing since 1999 to try to encourage oil, coal and gas companies to inform shareholders of their climate change-related risks and shift their investments into renewable sources of energy.

London, Jakarta, Shanghai and Houston and other global cities that are already sinking will become increasingly vulnerable to storms and flooding as a result of global warming, campaigners have warned ahead of a landmark new report on climate science.

While national leaders spout optimistic platitudes celebrating the great achievement of the globally unifying Paris Agreement on climate, environmentalists note that there is little in the way of substantial action plans behind the many promises made last December. Meanwhile, the most intense El Niño in history is leaving in its wake a world gripped by 7 months of record high temperatures; drought, water shortages, and famine (especially in India and Africa); wildfires (Fort McMurray, Canada); record coral bleaching; and a fast shrinking Arctic ice cap that set stunning early melt records this winter and spring.

A draft report from the UN Intergovernmental Panel on Climate Change estimates that the world will have to cut greenhouse gas emissions between 40% and 70% from 2010 levels by 2050 to limit global average temperature increases to 2° C above pre-industrial levels. The report summarizes the 3 major UN climate reports released over the past year.

The Science Based Targets initiative announced that 155 companies are now participating in its program to establish emissions goals in line with what scientists say is necessary to keep global warming below the 2 degrees Celsius threshold.

WASHINGTON (AP) -- The top official at the Environmental Protection Agency said Friday the ongoing legal fight over regulating carbon emissions from coal-fired power plants won't delay the nation's accelerating shift to cleaner sources of energy. EPA Administrator Gina McCarthy spoke at Climate Action 2016, a conference in Washington on efforts to curb global warming. Seeking to reassure her international audience, McCarthy said the United States will absolutely meet its obligations to cut carbon emissions as agreed to in the landmark climate treaty signed in Paris last December.

Oslo, Norway has a much more ambitious plan than most when it comes to cutting greenhouse gas emissions. The city plans to cut its emissions in half compared to 1990 levels, in only four years - faster than any city or country has made changes in the past. At the same time, if we want to keep global warming below 1.5 degrees Celsius, it's the pace we need.
