The best way to slow the rapid decline in Arctic sea ice is to reduce soot emissions from burning fossil fuels, wood, and dung. This is the conclusion of a Stanford University study published today in the Journal of Geophysical Research (Atmospheres).

GlobalWarmingisReal contributor Anders Hellum-Alexander wraps-up the climate and environmental news headlines for the past week:
- Canada’s CBC news covers the melting of the arctic ice cap. Some scientists originally thought that the melting of the ice cap would create vast areas of water that would absorb CO2, slowing atmospheric global warming. Now, some scientists think that the new open water will only absorb CO2 in surface level water. This would be good for the ocean as it will acidify less, but bad for the atmosphere as it will heat more. The solution? Stop emitting so much CO2.

In their monthly analysis just released of global land and ocean surface temperature data, the National Oceanic and Atmospheric Administration (NOAA) reports that June 2010 was the hottest on record. The average combined land and ocean surface temperatures for the period from April to June was the warmest on record, and year-to-date (January to June) is the second warmest, behind 2007. The analysis from NOAA’s National Climatic Data Center is based on records dating back to 1880.

Scientists at NASA and the National Snow and Ice Data Center published research last week in the Journal of Geophysical Research based on satellite microwave data of seasonal Arctic ice thaw from 1970 to 2009. The study indicates the seasonal Arctic sea ice melt melt season is now about 20 days longer than it was 30 years ago.

Research published in the journal Science late last week confirms that melting of the Greenland ice sheet has accelerated in recent years, and is contributing to seal level rise.
An average 273 gigatons of ice has melted away annually between 2006 to 2008, leading to three-hundredths of an inch of sea level rise, an increase of more the 60% over the average ice loss between 2000 and 2008. The data indicates an acceleration of ice loss in recent years, due in part to the unusually warm summers says lead researcher Michiel van den Broeke, a specialist in polar meteorology at Ultecht University.

Ice asks no questions, presents no arguments, reads no newspapers, listens to no debates. It is not burdened by ideology and carries no political baggage as it changes from solid to liquid. It just melts.”

Human activity is changing climate in ways not seen on Earth for at least the past 200,000 years. That’s the conclusion of new research published earlier this week in the Proceedings of the National Academies of Sciences, adding to the “large pile of evidence” that current climate change has diverged from the natural cyclical variation typical throughout the planet’s history, says the study’s lead author Yarrow Axford, a postdoctoral research associate at the University of Colorado’s Institute of Arctic and Alpine Research.

Cambridge professor Peter Wadhams made headlines yesterday when he said that data gathered from British explorer Pen Hadlow’s Arctic trek, called the Catlin Ice Survey, shows that Arctic summers will be entirely ice-free by 2020.
