Tropical rainforests are becoming less able to cope with rising global temperatures according to a study that has looked back over the way they have responded to variations in temperature in the past half a century. For each 1C rise in temperature, tropical regions now release about 2 billion extra tonnes of carbon-containing gases – such as carbon dioxide and methane – into the atmosphere, compared to the same amount of tropical warming in the 1960s and 1970s, the study found.
Chris Bretherton’s office on the seventh floor of the Atmospheric Sciences building at the University of Washington is like a scene from the Cloud City, only without the nonstop sunset. All that’s visible outside the plate-glass windows is an endless stream of cars filing across the I-5 bridge through the soup of Seattle’s infernal January fog.
Climate skeptics in Congress, and oil and coal industry lobbyists like the American Petroleum Institute (API) and the American Coal Council (ACC) may be preventing any significant action in the US on reducing this country’s emissions of carbon into the atmosphere, but at the Pentagon, and in the executive suites of the oil industry giants, there is no doubt about the reality of climate change.
As 2014 gets underway, humanity’s carbon emissions remain on course to catastrophically reshape the global climate over the next century or two. Global carbon emissions increased 1.4 percent in 2012, hitting an historic high of 31.6 billion metric tons released in a single year, according to a recent assessment by the International Energy Agency (IEA).
Scientists in Canada are up in arms over the recent closure of more than a dozen federal science libraries run by Fisheries and Oceans Canada (DFO) and Environment Canada. The closures were mostly completed by last autumn, but hit the headlines last week when pictures of dumpsters full of scientific journals and books began circulating online. Some of facilities that have been closed include the library at the century-old St.
STATE COLLEGE, Pa. — THE overwhelming consensus among climate scientists is that human-caused climate change is happening. Yet a fringe minority of our populace clings to an irrational rejection of well-established science. This virulent strain of anti-science infects the halls of Congress, the pages of leading newspapers and what we see on TV, leading to the appearance of a debate where none should exist.
Above image shows IASI methane levels on January 14, 2014, when levels as high as 2329 ppb were recorded. This raises a number of questions. Did these high methane levels originate from releases from the Arctic Ocean, and if so, how could such high methane releases occur from the seafloor of the Arctic Ocean at this time of year, when temperatures in the northern hemisphere are falling? Let's first establish where the methane releases occurred that caused these high levels. After all, high methane concentrations are visible at a number of areas, most prominently at three areas, i.e.
In May 2012 the UK Prime minister joined with other G8 leaders in reaffirming their respective national commitments to make their fair contribution to avoiding a 2°C rise in global temperatures (Camp David declaration). That is, the UK has committed to reduce its emissions of carbon dioxide, and hence its use of high carbon energy sources, in accordance with the science of climate change (the Copenhagen Accord). This weekend the Prime minister attributed the UK’s recent flooding and damaging weather, and hence at least some of the costs, to climate change.
Canada's carbon emissions will soar 38% by 2030 mainly due to expanding tar sands projects, according to the government's own projections.In a new report to the United Nations, the Harper administration says it expects emissions of 815million tonnes of CO2 in 2030, up from 590Mt in 1990.
