Climate Maps

ICNet members identified 21 climate indicators that are relevant to the transportation infrastructure community. The ICNet created a series of maps to illustrate the projected changes in these precipitation and temperature conditions in the northeast U.S. as global mean temperature (GMT) rises. For each of the 21 indicators below, you can view the historical conditions (1971-2000) alongside a map of projected future conditions that will result from successive increases in global mean temperature (+1°C, +2°C, and +3°C, or 1.8, 3.6, and 5.4°F, respectively).

When exactly these thresholds are reached depends on the trajectory of emissions, but based on a combination of models and scenarios, it is likely that they will be reached around 2020-2040 (+1°C), 2046-2065 (+2°C), and 2065-2084 (+3°C). However, these thresholds could be reached as early as 2009-2028 (+1°C), 2034-2053 (+2°C), and 2050-2069 (+3°C) under a high emission scenario or as late as 2052-2071 (+1°C), 2070-2089 (+2°C), and 2076-2095 (+3°C).

The maps here are a unique way of visualizing change based on temperature thresholds, regardless of the specific climate model or emissions scenario. For example, we can see how many more days each year the temperature exceeds 95°F in the region when the global mean temperature increases by 1, 2, and 3°C.


  1. Pick an indicator from the list below to start exploring these maps.
  2. Pick a level of projected global warming (1°C, 2°C, or 3°C) using the tabs.
  3. View or download the .jpg and GIS data on each page.
