Water scarcity resulting from climate change is the number one issue the world will have to grapple with in the future, according to chief climate scientist and Nobel Peace Prize-winner Dr. Rajendra K. Pachauri.

On the one hand, we will have more water around us with sea level rising. On the other hand, though, drought caused by climate change will leave possibly billions of people without clean water.

This will cause great health and global security issues. Most of these problems will be caused by water imbalances.

Even as the world prepares for the grand climate meet at Copenhagen this December, a large part of South India has gone under water. And while talks have already begun on coming up with an equitable deal and the very fear that there may be none, over 300 people have already lost their lives while millions are displaced and missing in this global warming related freak weather event, predicted well in advance by the IPCC in its Fourth Assessment Report in 2007.

700 people stripped naked in French vineyards this week. Why? To try to influence world leaders to do more regarding climate change.

Nike just announced that it is leaving its position on the US Chamber of Commerce board of directors because of the business organization’s opposition to climate action.

Nike doesn’t beat around the bush on why it is leaving the board.

A preliminary report issued last week by federal and local biologists and veterinarians from the U.S. Geographic Survey (USGS), U.S. Fish and Wildlife Service (FWS), Alaska SeaLife Center and the North Slope Borough Department of Wildlife Management,  found the 131 walruses likely died from being trampled to death by other walruses.   The dead animals, mostly calves and yearlings, were spotted in September on Icy Cape on the Chukchi Sea, southwest of Barrow, Alaska.  Read the rest of this entry »

“The United States is in a sense climate illiterate still,” Hans Schellnhuber, the director of Germany’s Potsdam Institute for Climate Impact Research said earlier this week.

He wasn’t just comparing the US to the EU, however. Even developing nations seem to know more about the issue and the potential results of inaction.

With the news that climate change is occurring at a faster rate than climate models have predicted, geoengineering solutions have been brought to the fore and are being taken more seriously. The main focus of these emergency geoengineering strategies is a reduction in “shortwave” radiation entering the Earth’s atmosphere via the solar wind.

The short-term goal here is an overall reduction in global atmospheric temperatures to slow, or even reverse, warming trends. These solutions include increasing the amount of reflective particles surrounding the Earth by placing reflective particles (“mirrors”) outside the atmosphere. Such a solution may be justified to quickly curtail an emergent crisis–such as the rapid disintegration of the polar icecaps. Another strategy is to blanket the upper atmosphere with sulfur particles to block shortwave energy from reaching the Earth’s surface, thus producing a pronounced cooling effect (of variable duration).

However, in a recently published paper, Climate Engineering Responses to Climate Emergencies by Blackstock et al, this and other controversial strategies are analyzed in terms of feasibility, short-term impact, and also, the potential risks and dangers. The authors are also calling for a study phase. The major criticism in the paper is that current geoengineering strategies focus on a reduction of temperature without due consideration of the impact on precipitation, which also drives climate change. The cooler the surface temperature, in general, the less overall precipitation ( due to the fact that there is less energy for evaporation). Focusing only on temperature reduction, via incoming solar radiation, could backfire, leading to a shift in global hydrology cycles and, possibly, drought. Also, sulfur in the atmosphere combines with water to form sulfuric acid–the primary source of “acid rain”–a problem dramatically reduced since the passage of the Clean Air act.

This week in the journal Nature scientists give the most comprehensive view of thinning ice sheets in Greenland and Antarctica to date.

Scientists from British Antarctic Survey (BAS) and the University of Bristol analyzed 50 million satellite measurements (from NASA) to show the massive ice loss on these polar giants.

The result are surprising, even to the scientists.

A new report ranks ten leading world cities on their greenhouse gas emissions. It also examines how and why the emissions differ.

As the report says, over 50% of the world’s population lives in urban areas. Leading cities of the world, global cities, are the places where greenhouse gas emissions really need to be cut. The greenest city from the study is Barcelona and the worst is Denver.
