Climate Crisis: NASA’s Projected Changes

NASA_global_warming_predAs the world’s foremost space agency, NASA has been at the forefront of climate research for many decades. Their contributions to this field of science has helped to shape our understanding of the planet’s past and has led to our current understanding of the Greenhouse Effect, Global Warming, and Climate Change. As a result, they are committed to educating the public about what’s in store for our blue planet in the near future.

Below are two videos that were recently released by NASA’s Goddard Space Flight Center. Both briefly, but succinctly, provide visualizations of what an average temperature increase of up to 5.5 Celsius (8 degrees Fahrenheit) and the resulting effect on weather patterns would look like, which is expected to happen by the end of the 21st century.

These visualizations – which highlight computer model projections from the draft National Climate Assessment – show how average temperatures and precipitation patterns could change across the U.S. in the coming decades under two different scenarios. As you can see, both predict significant warming and drying as a result of increased concentrations of CO2 in the upper atmosphere.

Projected Temperature Change by 2100:


Projected Precipitation Change by 2100:


The visualizations, which combine the results from 15 global climate models, present projections of temperature and precipitation changes from 2000 to 2100 compared to the historical average from 1970 -1999. They were produced by the Scientific Visualization Studio at NASA’s Goddard Space Flight Center, Greenbelt, Md., in collaboration with NOAA’s National Climatic Data Center and the Cooperative Institute for Climate and Satellites, both in Asheville, N.C.

Speaking on the subject of these videos, Allison Leidner, Ph.D. – a scientist who coordinates NASA’s involvement in the National Climate Assessment – said:

These visualizations communicate a picture of the impacts of climate change in a way that words do not. When I look at the scenarios for future temperature and precipitation, I really see how dramatically our nation’s climate could change.

But of course, these visualizations only tell part of the story. Far from this being a geographically restricted phenomena, residents inside the US are likely to be less severely hit than those people living in Sub-Saharan Africa, the Mediterranean, the Middle East, Central Asia, India and East Asia, where the problems of flooding, water loss, famine and drought area already common.

Add to this flooding coastlines, invasive parasites and diseases, militarized borders, potential skirmishes over dwindling resources, and a refugee crisis the likes of which the world has never seen, and you get a pretty good idea of why this issue matters as much as it does. The next century is going to be an interesting time. Here’s hoping we survive it!
