Tropical Planet

Tropics are widening as predicted by climate models, research finds,
Indiana University, September 17, 2018.


"The paper, "Re-examining Tropical Expansion," was published in the journal Nature Climate Change."

"Climate change should continue to expand the tropics over the next several decades," he said. "But the expansion may not continue at the rapid rate we've seen; at times it may even temporarily contract."

Rate of Expansion
"The authors conclude that the tropics have been widening at an average rate of about 0.2 degrees latitude, or about 17 miles, per decade in both the Northern and Southern hemispheres. The rate varies widely from year to year and from location to location."

Why this is Important
"...Widening of the tropics is important because it could be associated with severe changes in climate."

"...changes in the subtropical climate could affect billions of people."


Bottom Line

I’ve been noting that not just the size, but that the shape of the atmosphere wrapping around our planet, specifically, how our, “equatorial bulge,” and its seasonal transitions and patterns has already changed and is still changing.

This is disrupting traditional weather patterns around the world.
