Claim: Discovery Reveals Large, Year-Round Ozone Hole Over Tropics

An ozone hole, seven times larger than the Antarctic ozone hole, is currently sitting over tropical regions and has been since the 1980s, according to a Canadian researcher.

Update on NASA’s TROPICS-1 Mission

With four satellites, TROPICS will still provide improved time-resolved observations of tropical cyclones compared to traditional observing methods.

NASA to Launch 6 Small Satellites to Monitor, Study Tropical Cyclones

When launched, the TROPICS satellites will work together to provide near-hourly microwave observations of a storm’s precipitation, temperature, and humidity.

Study: Global Warming is Raising the Tropical Wet Bulb Maximum Temperature

According to a study, for every degree of warming, peak wet bulb temperature in the tropics also rises by a degree, so even a small amount of warming is a…

Of Warm Poles and Cold Tropics

Why are the poles warm and the tropics cold, and compared to what? An equivalent question is: what determines the difference in temperature between tropics and poles, and can we…
