Effects of global warming in the world

The Consequences of Global Warming On Weather Patterns
July 13, 2017 – 02:03 am

Warning signs today:

  • The number of category 4 and 5 storms has greatly increased over the past 35 years, along with ocean temperature.
  • Hurricane Katrina of August 2005 was the costliest and one of the deadliest hurricanes in U.S. history and caused economic losses in the order of $125 billion.

Drought and Wildfire

Warmer temperatures could increase the probability of drought. Greater evaporation, particularly during summer and fall, could exacerbate drought conditions and increase the risk of wildfires.

  • The 1999-2002 national drought was one of the three most extensive droughts in the last 40 years.
  • Warming may have lead to the increased drought frequency that the West has experienced over the last 30 years.
  • The 2006 wildland fire season set new records in both the number of reported fires as well as acres burned. Close to 100, 000 fires were reported and nearly 10 million acres burned, 125 percent above the 10-year average.
  • Firefighting expenditures have consistently totaled upwards of $1 billion per year.

Intense Rainstorms

Warmer temperatures increase the energy of the climatic system and can lead to heavier rainfall in some areas. Scientists project that climate change will increase the frequency of heavy rainstorms, putting many communities at risk for devastation from floods. Check the map of flood vulnerability in the United States.

  • National annual precipitation has increased between 5 and 10 percent since the early 20th century, largely the result of heavy downpours.
  • The Intergovernmental Panel on Climate Change reports that intense rain events have increased in frequency during the last 50 years and human-induced global warming most likely contributed to the trend.
  • According to the National Oceanic and Atmospheric Administration, the Northeast region had its wettest summer on record in 2006, exceeding the previous record by more than 1 inch.
