Several years have passed since studies conclusively demonstrated hat global warming is altering where and when many animals feed and breed.
In 2003, two benchmark reports showed that more than 100 species have shifted their ranges toward the poles at an average of 4 miles a decade and that thousands of others were emerging, migrating or breeding days to weeks earlier than they did a century ago... Read more [...]
Ecosystems, where will
animals move to survive? As climate change alters habitats and disrupts and will human development prevent them from getting there. The natural world is under siege by climate change.
Global warming is making hot days hotter, rainfall and flooding heavier, hurricanes stronger and droughts more severe.
This intensification of weather and climate extremes will be the most visible impact of global warming in our everyday lives. People who have the least ability to cope with these changes--the poor, very old, very young, or sick--are the most vulnerable... Read more [...] 
“Rains that are almost biblical, heat waves that don’t end, tornadoes that strike in savage swarms—there’s been a change in the weather lately. What’s going on?” Peter Miller, National Geographic.
There’s been a change in the weather. “Extreme events like the Nashville flood—described by officials as a once-in-a-millennium occurrence—are happening more frequently than they used to. A month before Nashville, torrential downpours dumped 11 inches of rain on Rio de Janeiro in 24 hours, triggering mudslides that buried hundreds. About three months after Nashville, record rains in Pakistan caused flooding that affected more than 20 million people. In late 2011 floods in Thailand submerged hundreds of factories near Bangkok, creating a worldwide shortage of computer hard drives. Read more [...] 
Until recently, many scientists spoke of climate change mainly as a “threat,” sometime in the future. But it is increasingly clear that we already live in the era of human-induced climate change, with a growing frequency of weather and climate extremes like heat waves, droughts, floods and fires. Today we will try to explain what’s going on with the fact that we experience very little or no rain at all; in certain places in the world such as Russia, the USA, Europe some part of Africa and in Asia.
Future precipitation trends, based on climate model projections for the coming fifth assessment from the Intergovernmental Panel on Climate Change, indicate that droughts of this length and severity will be commonplace through the end of the century unless human-induced carbon emissions are significantly reduced.
