CLIMATE PATTERN CHANGES 3 - global warming

Consequence: more intense rainstorms
Warmer temperatures increase the energy of the climatic system and lead to more intense rainfall at times in some areas.

    Warning signs today

  • National annual precipitation has increased between 5 and 10 percent since the early 20th century, largely the result of heavy downpours in some areas.

  • The IPCC reports that intense rain events have increased in frequency during the last 50 years, and human-induced global warming more likely than not contributed to the trend.

  • According to NOAA statistics, the Northeast region had its wettest summer on record in 2006, exceeding the previous record by more than 1 inch.
