A new study says that the Earth’s climate may be 50% more sensitive to long-term carbon dioxide changes in the atmosphere than in previous models, which should be adjusted to take this new information into account.

The United Nations (UN) launched a World Urban Campaign to promote socially and environmentally sustainable urban policies. The United States undertook this initiative in partnership with several entities after concluding that the world must unite to solve the problems caused by climate change, such as the increase of natural disasters and the energy and food crisis. This initiative was launched during the fifth session of the World Urban Forum in Rio de Janeiro.

Soil scientist at Cornell University Johannes Lehmann believes that biochar is the answer to global warming. Biochar is an ancient practice, only recently rediscovered, that transforms agricultural waste into a soil enhancer that can seize carbon, improve food security and discourage deforestation

During the International Climate Change Conference, in Cancun, Mexico, Google unveiled its latest product: the Google Earth Engine. According to the internet giant, the Google Earth Engine is an online environment monitoring platform that makes available to all a dynamic digital model of our planet, which is updated daily.

The Worldwatch Institute, a think tank for all things environmental, made a call for more small-scale agriculture projects in order to alleviate world hunger and poverty as well as fighting climate change. In its annual report, Worldwatch goes as far as saying specifically that industrial agriculture is not the answer for the troubles in the African continent.

It is thought that Global Warming is kick starting a sexual revolution among Arctic mammals, facilitating the appearance of hybrid offspring. University of Alaska evolutionary biologist Brendan Kelly theorizes that the rapid disappearance of the Arctic ice cap is removing the barrier that kept a number of species isolated from each other for at least ten thousand years.

A governmental report announced that the dwindling water supplies in western U.S.A. will see a further decline due to climate change, which could mean a lot of problems for millions of people. The flow of water in many of the largest west American river basins could be cut by up to 20% this century and these rivers provide water, from Texas to California, across eight US states.

The more data that comes available about climate change the more concerned we become. News from the Baltic Sea is worrying scientists:: climate change is turning the Baltic Sea into an increasingly freshwater sea with devastating consequences to its marine life.

Over the last 20 years more than 11,000 bird and butterfly species were analyzed in Europe in what is the largest study of its kind. Scientists are now releasing some of the data gathered during that period of time and one of the conclusions is that these species are not keeping up with the pace of climate change.

Carbon capture and sequestration (CCS) technologies will be at the forefront of international efforts to fight climate change. CCS technologies can be adopted to make cleaner electricity - not only from coal but also from heavy petroleum residues - and for that reason the European Union is looking into it with the ambition of introducing them as part of EU’s cap and trade scheme.
