How Hot Will Your City Get?


In the year 2100 summers in New York will be as hot as Juarez, Mexico is today. Los Angeles can look forward to summers that are as hot as they now get in Belize City.

Climate Central has released a new interactive map which tells you how hot your city will be in the year 2100 if carbon emissions continue as currently predicted. Shifting Cities allows you to choose from a large number of major cities around the world to find out how hot they will get in 2100. When you select a city on the map you are shown the current summer temperature in your city and a city which now has a temperature that your city can expect in the year 2100.


Climate Central's Shifting Cities map is part of a growing trend to map the future impact of climate change around the world. For example Climate Impact Lab's Climate Impact Map also visualizes how global warming will effect temperatures around the world over the rest of this century.

Using the drop-down menu on the Climate Impact Map you can choose to view predicted global temperatures for each quarter of the year or for the whole year. You can also choose to view the number of days which will be below 32 degrees Fahrenheit or above 35 degrees Fahrenheit. The timeline below the map allows you to view a choropleth view of any of these selected temperature predictions for the years 2020-2039, 2040-2059 and 2080-2100.

The map includes two choropleth views. The 'absolute level' shows the predicted temperatures around the world for the year selected. The 'change from historical' view shows how much the temperature will increase above the 1986-2005 averages around the globe.


The University of Hawaii has released a similar interactive map which uses expected temperature increases to predict the number of deadly days we can expect from extreme heat around the world for each year up to 2100. Heatwaves: Number of deadly heat days provides a timeline control which allows you to select any year from 1950-2100. The blue dots on the map show historic extreme heat events that have occurred around the world before 2014.

If you click on the map you can view two charts for the selected location. One chart visualizes the number of annual deadly days over time and the other shows the humidity vs. temperature for the current year.


Thanks to NOAA's Sea Level Rise Viewer we can observe how these increases in temperature will effect sea levels.

By the end of this century the National Climate Assessment estimates that sea levels may rise by up to 6.6 feet. NOAA's interactive map uses the most accurate elevation data available to model how different extents of sea level rise will impact coastal areas in the USA. You can adjust the sea level displayed on the map by adjusting the water level tool from 0-6 feet.

If you select the 'Local Scenarios' tab you can view the potential impact of different sea level rise scenarios on different areas of the country. The Local Scenarios option allows you to adjust the map to view the impact of sea level rise of different orders of severity. It also allows you to see how this impacts the local area by decade (up to the year 2100).
