Overview of climate change in the world [24].

Continent	Warming	Precipitation
Africa	Increased mean air temperatures; increased annual number of hot days and warm nights; heatwaves became longer and more intensive	Aridity increase due to decrease in precipitation in North Africa; increased trend of heavy rainfall followed by more frequent droughts in West Africa; more frequent and prolonged droughts in East and Southern Africa; increased number and intensity of extreme precipitation events in Southern Africa
Asia	Increased mean air temperatures followed by increased number of hot days and warm nights throughout continent; more frequent and longer heatwaves in South and East Asia	Observed annual precipitation trends are different depending on region; decreased precipitation and increased evapotranspiration are observed in West and Central Asia; increase in heavy precipitation in South, Southeast, and East Asia
Australia	Increased mean air temperature; heatwaves have increased in frequency and duration in most regions; increased number of extremely hot days	Increase in rainfall over northern Australia; decreased rainfall in southwestern and southeastern Australia in the period April–October; extreme rainfall intensities increased in many locations; less frequent droughts in northern and central Australia; more frequent droughts in southwest
Europe	Increased mean and maximum air temperatures in all regions followed by more frequent and prolonged heatwaves; increased occurrence of hot days and warm nights; cold extremes have decreased	Mean precipitation increased over Northern, Eastern, Western, and Central Europe; precipitation extremes increased in Northern and Eastern Europe; decreasing trend of precipitation observed in Mediterranean; more frequent droughts in Mediterranean; less frequent droughts in Northern Europe
Central and South America	Increase in the frequency and intensity of warm extremes and heatwave duration; increased mean and maximum temperatures; decrease in the intensity and frequency of cold extremes	Decreasing trend in precipitation in Central America; intensity and frequency of droughts have increased in many parts of Southern America; increasing trend of precipitation was observed in southeastern part of South America
North America	Increased mean and maximum air temperatures; increased occurrence of hot extreme events	Annual precipitation has increased in northern and eastern parts and decreased in western parts; increased frequency and intensity of heavy precipitation events in USA
