Global Temperature Rise Of 4.2 º C On The Cards

Copenhagen accord will fail to stem the continuing rise in global temperature.  An impending disaster could be the extinction of coral reefs, say by 2100.

A temperature rise of up to 4.2 º C has been predicted in a report published ahead of the next United Nations Climate Change Conference, which starts on 4 October in Tianjin, China.

Due to lack of global action to date, only a small chance remains for keeping the global temperature increase down to 2 º C as set as a target in the Accord, the report warns.

Looking at individual countries' agreed targets for emission levels, the report shows that many developed countries such as the USA and the European Union have set their aims very low, aiming at reaching emission levels just a few percent lower than 1990 levels by 2020. Only Japan and Norway are aiming to drastically reduce their emission to 25% and 30 to 40% below 1990 levels respectively.

Presenting their results in Environmental Research Letters, a group of international researchers from seven European research centres, has also found that even if nations would agree to a 50% reduction of emission levels by 2050 - a target that strong international agreements would greatly facilitate - there would still only be a less than 50% chance to keep global warming below 2 º C.

Rising global temperature levels would not be the only consequence of failing to raise the ambition level of future global emission reductions. Increasing ocean acidification, a direct result of growing atmospheric CO2 levels, could lead to a rapid decline of coral reefs and the marine ecosystem in the 21st century.

As the researchers write, urgent action is necessary, "It is clear from this analysis that higher ambitions for 2020 are necessary to keep the options for 2 º C and 1.5 º C open without relying on potentially infeasible reduction rates after 2020.

"In addition, the absence of a mid-century emission goal - towards which Parties as a whole can work and which serve as a yardstick of whether interim reductions by 2020 and 2030 are on the right track - is a critical deficit in the overall ambition level of the Copenhagen Accord."

Professor Dan Kammen, Editor-in-Chief Environmental Research Letters said, "The researchers provide an important lens on the ecological impacts and both social and ecological costs of inaction on climate protection."

I sure hope the temp is going up.If the global temperature is going up so should the temperature of small towns. To increase temperature at your thermometer is easy, to reduce it is hard over the years of recording. Example, you can collect temperature data of many city’s that show warming over the last 70 years, but some small towns near large city's show cooling. A much worse case.

click current week and click all. A chart from 1940 to 2010 shows a falling temp of -0.03 deg. F per year. The same is true for Kenton and Lima and a lot of other towns that did not put there thermometer on the cement in a parking lot, or on the roof like Columbus.[I guess that makes it man made.]Type in search box: Average Temp Wisconsin Rapids, Wisconsin click current week and click all. A chart from 1940 to 2010 shows a falling temp of -0.087 deg. F per year. I'm an old fart that remembers orange groves at the Florida, Georgia border. If we were in global warming all temperatures would be going up. This sample is every where, even England. Warming would be nice! I would love to have our orange groves back again! Some deeper water would not hurt anything either.
