A report from top climate scientists warns that such extreme weather like heat waves, floods and droughts will continue to trouble the world and disasters could become even more severe in the next few years.
The report from the Intergovernmental Panel for Climate Change (IPCC) will focus on extreme weather phenomenon that has decimated towns and killed thousands of people around the world.
"This is the largest effort that has ever been made to assess how extremes are changing," said Neville Nicholls, a professor at Monash University in Melbourne, Australia, and a coordinating lead author of one of the review's key chapters.
The draft summary of the report, obtained by the Associated Press, says that climate extremes have worsened because of man-made greenhouse gases. The report concludes that the frequency and magnitude of hot days will increase over the 21st century. It is very likely that heat waves will continue to increase over most land areas. Peak temperatures are likely to increase to 3.0 degrees Celsius by 2050 and 5.0 C by 2100. Droughts will intensify in parts of the globe like North America, northeastern Brazil and southern Africa.
As the world becomes hotter there will also be an upswing in rainfall and snowfall. Heavy rain will increase in the tropics. The warming seas will give cyclones more destructive power. Melting glaciers will trigger more landslides. Researchers have also predicted more intense monsoons with climate change. Warmer air can hold more water and impart more energy to weather systems, changing the dynamics of storms and where and how they hit.
