Climate change may cause the extinction of 82 percent of California's native fish species, including iconic ones such as Central Valley salmon and Delta smelt, according to a new study.
The peer-reviewed study by fishery experts at UC Davis created a framework to measure how vulnerable numerous species are to climate change. It assesses habitat conditions, climate change projections and temperature sensitivity for the 121 native and 50 nonnative fish species that inhabit California.

"The whole climatalogical system is being disrupted," said Shafqat Kakakhel, former deputy executive director of the U.N. Environment Programme and a leading voice on climate change in Pakistan. As temperatures continue to rise, he said, "you will either have monsoons too early or too much. It's happening in India, and it's happening in Pakistan."

America has some of the wildest weather on the planet, and it turns out those extremes – which run from heat waves and tornadoes to floods,hurricanes and droughts – carry a heavy price tag.
Climate studies have associated more frequent and intense weather events – such as heavy storms and heat waves – with climate change. The wild swings in weather across the midwest over the last few years – including heat waves, floods, and drought – have been cited as an example of what lies ahead with future climate change.
A report from the environmental research organisation World Watch Institute on Wednesday provided further evidence of the costs of those extreme shifts – known as "weather whiplash".

All countries should outline their long-term plans for curbing greenhouse gases next year, earlier than favoured by Washington, to revive the stalled fight against climate change, the European Union proposed on Tuesday.

If there’s a lesson David Ferguson has learned in his early years as a volcanologist, it’s this: Always carry a big hammer.
“You just have to pound away, smash as much rock as you can,” said Ferguson, a postdoc at Columbia University’s Lamont-Doherty Earth Observatory. “There’s nothing more frustrating than having gone all that way and then you discover your hammer isn’t big enough.”
He will need that persistence as he taps away at one of the most vexing problems in volcanology: Does the rock hold evidence that climate changes have, over time, caused a surge of volcanic eruptions?

Heidi Cullen, chief climatologist for Climate Central, appeared on CBS' "Face the Nation" on Sunday (May 26) to discuss the scientific evidence linking some recent extreme weather events to manmade global warming. She was part of a panel that also featured Marshall Shepherd, president of the American Meteorological Society; Jeffrey Kluger, science editor for Time Magazine; and WFOR's chief meteorologist David Bernard. Cullen said the science linking tornadoes, such as the EF-5 twister that struck Moore, Okla., on May., 20, is unclear, but more confidence exists about how global warming is affecting the odds of severe heat waves, rainstorms, and wildfires.

With global warming, the glaciers are melting. Once stretching to the edge of town, they now end high in the mountains. Moreover, their greenish glacial water is forming lakes. In summer, when the melting accelerates, floodwaters threaten the area. But the avalanche witnessed by Mr. Bomio shows that the shrinking of the glaciers removes a kind of buttress supporting parts of the mountains, menacing the region with rock slides.

About 13,000 years ago, the Northern Hemisphere experienced an episode of cooling (probably after a comet collided with the earth) that wiped out most species there. In the 14th century, a combination of climatic oscillations and major epidemics caused severe depopulation and disruption in much of Europe and Asia. In the 17th century, the planet experienced some of the coldest weather recorded in the past millennium. To the English poet John Milton, who experienced these catastrophes, it seemed like "a universe of death."

Governments worldwide must step up efforts to save the planet from global warming in the biggest challenge humanity has ever undertaken, according to United Nations’ climate chief Christiana Figueres.
Developing and industrialised nations aren’t doing enough to prevent the global temperature rising 2 degrees Celsius from pre-industrial times, Figueres said in an interview during the Carbon Expo conference in Barcelona. The global average has already risen by about 0.8 of a degree in the past century, according to the National Research Council in Washington.
“While it’s clear that governments at an international level are walking in the same direction, it is also clear that they’re doing so at a pace that is unacceptable to science,” Figueres said. “Science requires an acceleration both in the scale and the speed of national efforts.”

Irrationally we give space to big round numbers, inject them with meaning and use them to reflect or trigger alarm. It was odd, then, that when a round number came along, symbolic of a genuine threat to stable civilisation, one that was worthy of reflection if not a little alarm, it caused barely a ripple. Newspapers especially, for whom marking round numbers is the easiest excuse to report an issue and fill pages, mostly yawned with disinterest.

Rimba Raya, the world's largest REDD+ project, has finally been approved by the Indonesian government and verified under the Verified Carbon Standard (VCS), a leading certification standard for carbon credits.
The 64,000-hectare forest carbon project in Indonesia's Central Kalimantan Province on the island of Borneo is expected to reduce carbon dioxide emissions by 119 million tons over its 30-year life-span. The emissions reductions will come from avoiding drainage of area's carbon dense peatlands and conversion of its forests to oil palm plantations.
