The Future Climate of America



The extreme wildfires currently blazing in much of the Western United States could be the new normal. At least according to a new map from the New York Times. And it isn't just the Wesstern United States which can look forward to a future of extreme climatic events. Every single county in the USA faces some sort of emerging climate threat.

Earlier this week ProPublica mapped out data from the Rhodium Group to show how climate change will drive agriculture and the habitable zone northward in the United States. In New Climate Maps Show a Transformed United States ProPublica show how different parts of the U.S. are likely to be affected by global heating. Their map shows where extreme heat will become commonplace, where growing food will become very difficult and where dangerous 'wet bulb' conditions will become the norm.

The New York Times has now also released an interactive map which attempts to explain how global heating will effect the climate where you live. If you enter your county into Every Place Has Its Own Climate Risk. What Is It Where You Live? you can find out which climate risks will become most extreme in your area.

The NYT's interactive map colors areas of the United States to show the climate risks which will be most extreme in different part of the USA. For example most of the East Coast will face increased risks from severe hurricanes, much of the Midwest will experience extreme heat, the Western states will face extreme droughts and the most Western states will see higher risk from wildfire. If you hover over your county on the map you can see the risks that your county will face in six different categories; hurricane risk, extreme rainfall risk, water stress risk, sea level rise risk, heat stress risk and wildfire risk.



Of course as a result of global heating most counties will experience higher average temperatures. Earlier this year the National Geographic released a new interactive feature which shows you how hot your area will become by comparing it to a city which currently experiences average temperatures that your home town can expect in the year 2070.

If carbon emissions continue to rise at the current rate then by 2070 the world will experience devastating climate change. For example Boston, Massachusetts will experiences temperatures 5 degrees centigrade hotter than today and 49 mm more rain will fall. This is similar to the climate that Bardwell, Kentucky has today.

In Your Climate, Changed the National Geographic uses an interactive map to show the future climate analogs of 2,500 cities around the world. These analogs are based on worst-case climate change scenario assumptions. The map automatically detects your location to show you your nearest future global heating twin. The map also explains what kind of climate zone your city currently experiences and compares that to the likely climate it will have in 2070.
