African's leading spokesperson on climate change does not hold high hopes for upcoming climate talks in Cancun, Mexico; saying they will be a "total flop" and will not eventuate in a deliver set targets for greenhouse gas emissions reduction. Read more

October 15 - Americans' global warming understanding
A recent survey has found found that only half of Americans understand global warming's main cause is the activity of humans and only 43% know what the greenhouse effect is. The Yale University study also found 63 percent of Americans believe that global warming is happening, but many do not understand why. Read more

October 13 - Tasmania to feel the heat
According to new climate modelling, if carbon emissions continue at the current rate, Australia's island state of Tasmania could be 3 degrees Celsius hotter by the end of this century. Tasmania contains many sensitive habitats that could be severely impacted by such an increase. Read more.

October 12 - Birth control the answer to climate change?
The Earth's population could reach 9 billion by 2050, but a new analysis from U.S. National Center for Atmospheric Research has found that by somehow curtailing that growth to 8 billion it could save  at least 1.4 billion metric tons of carbon from entering the atmosphere each year by 2050. Read more

October 11 - Earth's water cycle "pushed to the limit"
The amount of water evaporating from the land into the atmosphere hit a maximum 12 years ago and is now dropping according to researchers from the Max Planck Institute for Biogeochemistry. The researchers says as the atmosphere is now warmer, it can hold more water, effectively trapping it and leaving less water available on the surface for maintaining the cycle. Read more

October 10 - Glaciers threatened in China
Glacial coverage in western China may decrease by close to 30 percent by 2050 due to global warming and cropping. Extreme drought currently affects 697,000 square kilometres of China and drought is impacting 2.98 million square kilometres, which is over 38% percent of China's land area.  Read more

October 9 - Increased fresh water flows into oceans
University of California Irvine researchers have the amount of fresh water flowing into the world's oceans has increased significantly. 18 percent more fresh water reached the oceans between 1994 and 2006, an average yearly rise of 1.5 percent. Among the causes are more frequent storms dumping water on land which then runs off into the sea, but instead of this being good news, it seems wet regions are just getting wetter and dry regions drier.
