Why Misleading Americans About Climate Change Is Dangerous

Many Republicans claim the science on climate change is murky, but in fact the scientific consensus is clear — and making people aware of that fact can change their minds.

Daily chart: Down under and dirty: Australia's carbon footprint

Tue, 2015-08-11 11:34
“WE ARE not leading but we certainly aren’t lagging,” declared Tony Abbott, Australia’s prime minister, of his country’s pledge on August 11th to cut carbon emissions 26% by 2030. Measured against a 2005 baseline, Australia’s plans come ahead of the United Nations climate change conference later this year. They are meagre compared with those proposed by America and the European Union, however, and speak to recent strife over Australia’s climate policies. The country’s Liberal-National coalition, in power since 2013, has slashed renewable energy targets and repealed carbon and mining taxes. Mr Abbott, a proud climate-change sceptic, believes coal is “good for humanity”—convenient given how much of the stuff Australia has as the world’s fifth-largest producer.  But the country is already suffering thanks to climate change from manmade emissions: seven of the hottest ten years there have occurred since 1988. Australians emit more carbon per person than do residents of Saudi Arabia, Canada and America. Their nation’s weak pledge to reduce them will do little to help, and perhaps much to harm, efforts to limit global warming to just 2°C. 20150811 15:27:02

[Research Article] Abrupt warming events drove Late Pleistocene Holarctic megafaunal turnover

Thu, 2015-08-06 20:00
The mechanisms of Late Pleistocene megafauna extinctions remain fiercely contested, with human impact or climate change cited as principal drivers. We compared ancient DNA and radiocarbon data from 31 detailed time series of regional megafaunal extinctions and replacements over the past 56,000 years with standard and new combined records of Northern Hemisphere climate in the Late Pleistocene. Unexpectedly, rapid climate changes associated with interstadial warming events are strongly associated with the regional replacement or extinction of major genetic clades or species of megafauna. The presence of many cryptic biotic transitions before the Pleistocene/Holocene boundary revealed by ancient DNA confirms the importance of climate change in megafaunal population extinctions and suggests that metapopulation structures necessary to survive such repeated and rapid climatic shifts were susceptible to human impacts.

Climate change and the president: Hotter than August

UK Only Article:  standard article Issue:  Time to fix patents Fly Title:  Climate change and the president Rubric:  New rules to curb emissions from power plants are not as bold as they seem Main image:  20150808_USP001_0.jpg “I AM convinced that no challenge poses a greater threat to our future, to future generations, than a changing climate,” declared Barack Obama on August 3rd. The president’s announcement of America’s first national standards to limit carbon-dioxide emissions from power plants had to be moved indoors to escape the sweltering weather. The response from Mr Obama’s political opponents was even hotter. Mitch McConnell, the Senate majority leader, described the new rules as, “a triumph of ideology over sound policy and honest compassion”. He encouraged states to ignore them. In political terms, Mr Obama’s new rules are momentous. As far as their likely impact on the climate or on America’s energy sector are concerned, they are more modest than the claims made by either side would ...

Cluster bombing

Thu, 2015-08-06 11:10

THE outbreak of Ebola fever in Guinea, Liberia and Sierra Leone, which has killed more than 11,000 people, has dropped out of the news as it has been brought under control. Although new cases are now measured in dozens, rather than hundreds, a week, the disease has not been stamped out—and a new epidemic could flare up somewhere else at any time. A vaccine against the virus responsible would be of enormous value. And a paper in the Lancet suggests one is now available.

The vaccine, developed by the Public Health Agency of Canada and called rVSV-ZEBOV, smuggles one of the Ebola virus’s coat proteins into a person’s body in a Trojan horse called a vesicular stomatitis virus. This horse-and-cattle virus does not cause human illness, but its presence is enough to activate the immune system, which learns to recognise and react to the Ebola coat protein—and thus, the vaccine’s inventors hope, to clobber Ebola if it should encounter it.

The trial that the Lancet reports was conducted on more than 7,600 people in Guinea by a group of researchers led by Marie Paule Kieny of the World Health Organisation and John-Arne Rottingen of the Norwegian Institute of Public Health. It involved a procedure called ring vaccination, in which clusters of people who were particularly at risk were offered the chance to be...

River buries permafrost carbon at sea

Wed, 2015-08-05 14:02
As temperatures rise, some of the organic carbon stored in Arctic permafrost meets an unexpected fate -- burial at sea. As many as 2.2 million metric tons of organic carbon per year are swept along by a single river system into Arctic Ocean sediment, according to a new study.

Greenhouse gases' millennia-long ocean legacy

Mon, 2015-08-03 15:50
Continuing current carbon dioxide emission trends throughout this century and beyond would leave a legacy of heat and acidity in the deep ocean. These changes would linger even if the atmospheric carbon dioxide concentration were to be restored to pre-industrial levels at some point in the future, according to a new paper. This is due to the tremendous inertia of the ocean system.

Carbon dioxide removal cannot save the oceans if we pursue business as usual

Mon, 2015-08-03 15:50
Greenhouse-gas emissions from human activities do not only cause rapid warming of the seas, but also ocean acidification at an unprecedented rate. Artificial carbon dioxide removal (CDR) from the atmosphere has been proposed to reduce both risks to marine life. A new study based on computer calculations now shows that this strategy would not work if applied too late. CDR cannot compensate for soaring business-as-usual emissions throughout the century and beyond.
