Links between Climate Change and Extreme Weather

Climate-ChangeExperts have suggested that climate change will have the impacts on the number, severity and location of extreme weather events. More energy will be added to the atmosphere, as the atmosphere can hold more water vapors with increase in warming.

Based on this alone, there should be decline in cold weather events and rise in heat waves. Moreover, there would be changes in the intensity of the dry and wet periods attributable to droughts and floods.

The earth's system is, however, very complex and has natural variability. El Nino and La Nina events are good example of this, along with important local and regional variations.

Studies are needed to be conducted over a period of long time to figure out statistically significant trends from small datasets.

Intergovernmental Panel on Climate Change has reviewed scientific research on extreme weather.

The researchers said that they have found enough evidence that the number of extreme cold days around the world are declining, whereas the hot days are increasing. Moreover, the patterns of rainfalls in many regions are being altered.

Levels of global sea have also been found to rise more than 3mm per year. Researchers said that climate change may be affecting extreme weather in the UK by means of very wet periods. This leads to river and flash floods, and sea level rise, which increases the risk of coastal flooding.
