Around the world, C40 cities are taking bold climate action, leading the way towards a healthier and more sustainable future. The C40 Knowledge Hub is being regularly updated with resources and articles for cities seeking to better understand and respond to the COVID pandemic. The expanding library includes policy briefs, profiles of city solutions, commentary from mayors and city decision-makers, and an index of relevant media, data sets, peer-to-peer support, and more. Now is the time to act! Human civilisation is facing an environmental crisis on a global scale. Changes Of Climate Change Across Earth.

The central contradiction of climate change is that it is at once the most epic problem that our species has ever faced yet it is largely invisible to the average human. From the comfort of your home, you may not realize how climate change is already affecting mental healthor ripping apart ecosystemsor how cities like Los Angeles are taking drastic measures to prepare for water shortages. But a new interactive map is perhaps one of the best visualizations yet of how climate change will transform America. Click on your city, and the map will pinpoint a modern analog city Changes Of Climate Change Across Earth matches what your climate may be in Fitzpatrick looked at urban areas in North America using three primary datasets.

One captured current climatic conditions an average of the years between andthe second contained projections of future climates, and the third provided historic climate variability from year to year taken from NOAA weather records. Depending on the city, climate might be more "stable," or swing more wildly between years. On the West Coast, cities look generally like places straight south of them.

Also, the map has an option on its left side that uses a different calculation to show what the shifts would look like if emissions peak around and begin to fall. The implications are shocking, but also potentially useful. Take extreme heat, for Cbange. But in a place like San Francisco, air conditioning is a rarity. Another major consideration is water. Many urban areas will get drier, but others may see their total precipitation remain unchanged. However, the patterns of rainfall could change—to all fall in the winter, for instance.

San Francisco could stand to learn some water management techniques from its analog. Climate models predict that in the coming decades, LA will see fewer, yet more intense rainstorms. So to prepare, the city has begun an ambitious program to capture those huge Climatd of water with a network of cisterns built into road medians. The rain capture program reduces its reliance on water piped into the city from afar. The Bay Area, which has been historically blessed with more rainwater than its neighbor down south, hasn't been so forward-thinking. Rich communities have thrown hissy fits when new water requirements meant their lawns would— gasp —turn brown.

Changes in rainfall would have serious implications for agriculture, of course.

But something more subtle will also unfold: As the climate changes, so too will the makeup of local ecosystems. Pests like mosquitos, for example, could boom in your community. Certain plant species might not be able to handle the sudden shift and die out.

More frightening still, some of the North American cities that Fitzpatrick explored will have no modern equivalent in To be clear, though, this climate analog technique simplifies things—for instance, the researchers left out complicating factors like the urban heat island effect, in which cities absorb more heat than surrounding rural areas. And this is average climatenot weather. So for instance, the recent cold snap on the East Coast was generated by warmer temperatures in the Atlantic. It's overly simplifying. Still, the idea with this new interactive map is to better visualize—both for regular citizens and policymakers—what has previously been presented as impenetrable datasets.
