[lbo-talk] NO TIME FOR CLIMATE CHANGE?

*NO TIME FOR CLIMATE CHANGE?* The climate conference in Durbin seems to be earning more derision than these things normally do. This stems from frustration with governments' inaction on the part of most normal people, and dismissal of climate change science altogether by the goon squads right wing. (Now it's reported that John Huntsman, formerly known as the only sane candidate in the GOP race, has flipped on climate change.) But from the panel of scientists that study climate change <http://www.ipcc.ch/> came this last week regarding extreme events as a result of climate change. Co-chair Thomas Stocker was speaking:

I now would like to summarize the most important findings:

• It is very likely that the number of extreme warm days and nights has increased worldwide since 1950, and this is likely due to the increase of greenhouse gas concentrations.

• In the future, for the higher emissions scenarios, what is today a 1-in-20 year hottest day will become a 1-in-2 year event. This means the frequency of these extreme events will increase by a factor of about 4 in the next 30 to 40 years and by a factor of 10 by the end of the 21st century.

• In consequence, heat waves are projected to very likely last longer, to occur more frequently and to increase in intensity.

• Heavy precipitation has intensified on a global scale and with medium confidence this is already attributed to anthropogenic climate change. It is likely that a 1-in-20 year event of heavy precipitation will become a 1-in-5 to 1-in-15 year event by the end of the 21st century.

• Tropical cyclone activity is in the focus of many countries because their impact can be devastating. While there is low confidence of observed long-term trends over the past four decades, is likely that maximum wind speed will increase in the 21 century in response to the warming.

• More intense and longer droughts have been observed in some regions, and there is medium confidence that they will intensify in the 21st century, particularly in S Europe, in the Mediterranean, Central North America and Mexico, NE Brazil and Southern Africa.
