|Arctic sea-ice volume (red line is 2012) from |
Neven, Climate Progress, 4 August 2012
I think it’s pretty safe to say that we’re going to have a new record volume low, although the difference with 2010 and 2011 has become smaller. Right now it’s 1249 and 730 km3 respectively.

PICKS OF THE WEEK
Climate policy and our sphere of influence
Fergus Green, Inside Story, 2 August 2012

Victory declared for the climate denialists
Graham Readfearn, The Drum, 2 August 2012
A victory has been declared in the field of climate change, but the lap of honour is not being run by research scientists or renewable energy bosses, or by coral reefs, drought-stricken farmers or the citizens of low-lying countries.
A Dark Victory: How vested interests defeated climate science
Robert Manne, The Monthly, August 2012
As greenhouse gas emissions have continued to rise, as evidence of global warming has continued to grow, as the unwillingness of the world to act to curb emissions has become increasingly clear, a determination not to notice the looming catastrophe has taken hold of large parts of the population.

Farmers: Biofuels Quota Exacerbating 'Food Crisis'
Suzanne Goldenberg, The Guardian, July 31, 2012
Some of the largest farmers in the US are warning the government that the mandated biofuels provisions that demand grain crops to be converted into ethanol for gasoline will make an impending "food crisis" much worse
Visualising climate change
How can something that is largely ‘invisible’ be communicated using visual tools? This is the question that Professor Stephen Sheppard asks in this guest blog post, summarising some of the research in his new book ‘Visualizing Climate Change‘.

Climate Change Study Ties Recent Heat Waves To Global Warming
Seth Borenstein, Huffington Post, 4 August 2012
The relentless, weather-gone-crazy type of heat that has blistered the United States and other parts of the world in recent years is so rare that it can't be anything but man-made global warming, says a new statistical analysis from a top government scientist.

ScienceDaily, July 29, 2012
The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, scientists have concluded, but they say those conditions will become the "new normal" for most of the coming century.

1988 vs 2012: How heat waves and droughts fuel climate perception
Nathanael Massey, ClimateWire, July 30, 2012
A crop-searing drought grips the Midwest and Southeast. In the Rocky Mountains, extraordinary "superfires" rip through thousands of acres of high-elevation pine. The Mississippi River runs so low that barge traffic must be slowed, at times suspended. Across the country, roads buckle under the heat.
Juiced by Climate Change: Extreme Weather On Steroids
Stephanie Hanson Damassa and Noreen Nielsen, CAP, 1 August 2012
The brutal summer of 2012 is what climate change looks like. It’s only the beginning of August, and yet nearly every corner of the United States has suffered through extreme weather such as oppressive heat waves, damaging storms, and devastating droughts and wildfires
When It Rains, It Pours: New Study Finds Extreme Snowstorms And Deluges Are Becoming More Frequent And More Severe
Climate Progress, July 31, 2012
As our climate warms, wet areas will generally get wetter (and dry areas drier). One of the consequences of global warming is the severity and frequency of rain and snow storms – fueled by the increase moisture in the atmosphere as the air warms.

Smelling a leak: Is the natural gas industry buying academics?
Tim McDonnell. Grist, 30 July 2012
Last week, the University of Texas provost announced he would reexamine a report by a UT professor that said fracking was safe for groundwater after the revelation that the professor pocketed hundreds of thousands of dollars from a Texas natural gas developer. It’s the latest fusillade in the ongoing battle over the basic facts of fracking in America

SCIENCE AND IMPACTS
Tightened constraints on the time-lag between Antarctic temperature and CO2 during the last deglaciation
We show that the increase in CO2 likely lagged the increase in regional Antarctic temperature by less than 400 yr and that even a short lead of CO2 over temperature cannot be excluded. This result, consistent for both CO2 records, implies a faster coupling between temperature and CO2 than previous estimates, which had permitted up to millennial-scale lag
Nature soaks up more greenhouse gases, brakes warming
Alister Doyle, Reuters, 1 August 2012

Climate Change’s Costs Hit the Plate
Thomas Homer-Dixon, Toronto Globe and Mail, July 24, 20
In the past few years, agricultural scientists have shown that crops critical to humankind’s caloric supply – including corn and soybeans – are extremely sensitive to even short periods of high temperature. Output of these crops increases as the temperature rises to about 30 Celsius, but then it falls sharply as the temperature keeps rising.
Study Shows Planet Keeping Pace With CO2 Emissions
Michael D. Lemonick, Climate Central, August 1st, 2012
Climate change is a serious enough problem, but it could be a lot worse. About half of the carbon dioxide we’ve pumped into the atmosphere by burning fossil fuels has been absorbed by plants and oceans, rather than staying in circulation to drive up temperatures.
