Global warming increases heat waves, drought, wildfires, storms and floods
It was always predictable by the basic science that constant atmospheric GHG pollution, with increasing GHGs in the atmosphere, would lead to increased extreme weather. Global warming will increase extreme heat leading to increased drought, which together will increase the risk of wildfires. Global warming increases atmospheric water vapor because warm air holds more water vapor, and water vapor feedback increases warming.
In fact it has been long established that for every one degree C of warming the air will hold 7% more water (the Clausius–Clapeyron equation).
The increased GHG heat in the lower atmosphere increases lower atmosphere energy energizing of the hydrological cycle, leading to stronger winds, more heavy rains and flooding.
The strength of cyclonic storms, such as hurricanes, is increased by increased lower atmosphere energy and surface ocean warming.
As global warming increases, climate extremes increase along with the average temperature and climate. The most obvious is heat waves.
Global warming has so far significantly increased extreme heat events.
Computer models studies confirm that as global warming rises so will heat waves. By 2040 the areas affected will have increased several fold, and we are committed to this by climate system inertia.
Climatic warming of about 0.5 ° C in the global mean since the 1970s has strongly increased the occurrence-probability of heat extremes on monthly to seasonal time scales. For the near-term (i.e., by 2040), the models predict a robust, several-fold increase in the frequency of such heat extremes, irrespective of the emission scenario. Unmitigated climate change causes most (>50%) continental regions to move to a new climatic regime with the coldest summer months by the end of the century substantially hotter than the hottest experienced today.
