This study takes a look at global warming and growing concerns for available water. Even if we can keep the globe from warming above the internationally set target of 3.6 degrees, an additional 500 million people (8% of the population) could be exposed to water scarcity.

Due to the federal government shutdown, NASA websites and most NOAA websites are unavailable. Due to the lapse in funding, research is on hold. Specific NOAA sites necessary to protect lives and property are operational and will be maintained.

Story Highlights

  • Just as there are regional variations in rainfall and temperature trends over time, there are seasonal variations.

  • These two graphics break down the Fall (September, October, November) rainfall and temperature trends since 1970

  • Even with regional fall cooling trends, all states have been experiencing an annual warming trend since 1970.

Clocks changing, foliage turning, apple picking. All the signs of fall are upon us or fast approaching. With that in mind, we wanted to share trend maps showing how both precipitation and temperature have changed this season since 1970.

Just as New Mexicans are roasting chiles while New Englanders are making apple cider, there are noticeable differences in regional trends. On the precipitation side, it’s clear fall on the Eastern Seaboard and the Ohio River Valley has gotten wetter while its gotten dryer for many areas to the west. The trend in the Northeast is particularly striking and according to a NOAA report, it stretches back to the beginning of the 20th century.

Temperature trends are somewhat more uniform. The strongest trend is noticeable west of the Mississippi, parts of which have warmed up to 1.3°F per decade. The Northeast is also one of the fastest warming regions of the country. Only small pockets of the Southeast have seen any form of cooling in the fall. That doesn't mean global warming is skipping over the region. Annual temperatures trends show that all states in the Southeast (and across the U.S. for that matter) have been warming since 1970, although at different rates. For example, Florida is the slowest warming state while Arizona is the fastest, and Utah comes in at number seven.

Looking to the future, fall is likely to only get hotter for the Southwest. According to the National Climate Assessment, temperatures in the region will rise 5°F to 9°F by the end of the century with the steepest increases coming in fall and summer. All other regions and states, including Florida, will also likely see temperatures continue to rise. That could push back fall harvesting seasons, longer frost free seasons, and as we noted last week, have an impact on foliage.

  • Warmer fall days are altering animal migration patterns, particularly waterfowl. Those higher temperatures translate into ducks staying further north, which can delay the onset of prime hunting season and reduce the overall number of birds coming through the Chesapeake Bay region.

  • Fall warming is heating up the waters of the Chesapeake and allowing MSX and Dermo, deadly oyster diseases, to linger longer and decimate already depleted oyster stocks.

  • The higher summer and fall temperatures are expected to affect air quality adversely. For example, the release of pollen and other airborne allergens will increase with the changing seasons.

  • While most Lyme disease cases occur during the summer, the season could extend into fall as temperatures warm.
