Large areas of forests in our country are vulnerable to drought, fires and disease. When forests are heavily damaged, there are well-known local impacts: drier soils, stronger winds, increased erosion, loss of shade and loss of habitat.
In 2017, the United States spent a record $306 billion on weather and climate-related disasters, making it the costliest and most damaging year on record. The wildfires out west, Hurricanes Irma, Maria, and Harvey, the Minnesota hailstorm, and the midwest drought are just some of the costly examples. Officials say that already-bloated figure will increase further in the coming years as temperatures rise.
The Arctic has been experiencing record warm temperatures and record low sea ice levels. During February, there were nine days in a row with temperatures averaging 27 degrees above normal and often above freezing. Over the previous 20 years, there were only two previous readings above freezing in February – once in 2011 and once last year.
On Monday, August 21, there will be a total solar eclipse visible in a band across the entire contiguous United States. The last time that happened was in June of 1918. In fact, the last time a total solar eclipse was visible anywhere at all in the continental U.S. was in 1979. So, this is a big deal for American eclipse watchers and millions of us will be heading for some part of the 65-mile-wide band of totality that wends its way from Oregon to South Carolina.
The changing climate is having a marked effect on forests in this country. In particular, trees along the U.S. eastern seaboard are changing their range as they slowly seek to escape rising temperatures.
