CLIMATE CHANGE MAKING GLOBAL RAINFALL PATTERNS MORE VOLATILE AND MAY COME IN THE FORM OF WORSE DROUGHTS.

The experts say that climate change making global rainfall pattern more volatile and increase is largely the result of human caused greenhouse gas emissions, which have created a hotter and more humid atmosphere, more intense rain events and greater swings between them and same is the affect of the forest on fires which also creats hotter and more humid atmosphere. The volatility might come in the form of worse droughts. Or it might mean much bigger increase in the extreme rainfall and flooding. The variability would worsen under the climate change, but these new findings would show rainfall variability has already worsened over the past hundred years. Past studies of the record and information of climate change either focused on long term average rainfall which is not systematically changing globally, or rainfall extremes where changes are hard to measure accurately. This study looks solely at variability, which refers to uneven timing and amount of the rainfall. Alarmingly the problem will worsen as global warming continues and will raise the risks of droughts and floods. The research shows a systematic increase in rainfall variability since the 1900s.Day to day rainfall variability increased by 1.2 percent per decade, globally. The trend was more pronounced in the latter half of the century, after 1950.The increase in invariability means rain is more unevenly distributed over the time. To come to grips with these findings, it helps to understand the factors that determine how much heavy rain a storm produces, and how these factors are being affected by global warming. Earth has warmed 1.5degree C since the industrial revolution, equating to a ten percent increase in water vapour in the lower atmosphere. So this is driving storms to become rainier, however climate change showing the after affects impacting the rainfall as abnormal and heeding the warning for future.
