VIDEO: NASA releases heat map of warming Earth
NASA has released a visualization showing our planet’s warming temperature since 1880.
The map starts out mostly blue, changes towards yellow in the 1930’s, and cools a bit in the 50’s and 60’s.
As the 1970’s move into the 80’s, the map quickly changes yellow, then spikes towards dark orange hues up to today.
Researchers say it will become harder to feed humans as the temperature climbs.
That’s because photosynthesis, the process plants use to create food and grow, declines quickly once the mercury reaches 35 degrees celcius.
Even more troubling— scientists have found eerie similarities between what’s happening on Earth, and what happened to Venus.
The atmosphere traps heat from the Sun, causing a runaway greenhouse effect there.
It makes Venus so hot, the average daytime temperature is over 475 degrees.
