Before you do anything else, you might want to read David Leonhardt’s N.Y. Times piece explaining the connection of global warming to extreme rainfall…



Precipitation can have wide-ranging effects on human well-being and ecosystems. Rainfall, snowfall, and the timing of snowmelt can all affect the amount of surface water and groundwater available for drinking, irrigation, and industry. They also influence river flooding and can determine what types of animals and plants (including crops) can survive in a particular place. Changes in precipitation can disrupt a wide range of natural processes, particularly if these changes occur more quickly than plant and animal species can adapt. (-Source EPA)

Current climate models indicate that rising temperatures will intensify the Earth’s water cycle, increasing evaporation. Increased evaporation will result in more frequent and intense storms, but will also contribute to drying over some land areas. As a result, storm-affected areas are likely to experience increases in precipitation and increased risk of flooding, while areas located far away from storm tracks are likely to experience less precipitation and increased risk of drought.

June broke records because it was so hot. So far July has been cool and unusually wet, something that comes as no surprise to Massachusetts residents who have seen an unending series of sprinkles, showers,…

Human activity influencing global rainfall, study finds

Human activity such as such as greenhouse gas emissions and land use change were a key factor in extreme precipitation events such as flooding and landslides around the world, a study has found. In recent…

Increases in extreme precipitation cost the U.S. $73 billion over three decades

By YCC Team   05/18/21  
Torrential rain storms can flood homes, wash out roads and bridges, and destroy crops. Over the past three decades, flooding from heavy precipitation has caused about $200 billion of damage in the U.S.

Antarctic ice-sheet melting to lift sea level higher than thought, study says

By Harvard University  Photo: Michael Weber   04/30/21  
Global sea level rise associated with the possible collapse of the West Antarctic Ice Sheet has been significantly underestimated in previous studies, meaning sea level in a warming world will be greater than anticipated, according…

Irma, and the Rise of Extreme Rain

By David Leonhardt   09/12/17  
Warm air can carry more water than cool air. You may understand this fact intuitively even if you don’t realize it. The greater moisture of warm air explains why your skin doesn’t get as dry…
