The Stratosphere is shrinking (click here) and now the trophosphere is expanding. This is NOT good news. How can anyone ignore this? This is serious and the warming needs to stop by reducing greenhouse gases n the troposhere in large amounts. NOW. This is not going to wait until 2050.
GET OVER IT!
Stop denying the truth telling by scientists.

Weather balloon measurements, taken in the Northern Hemisphere over the past 40 years, reveal that the lowest layer of Earth's atmosphere — called the troposphere — has been expanding upward at a rate of roughly 164 feet (50 meters) per decade, and climate change is the cause, according to findings published Nov.r 5 in the journal Science Advances.
"This is an unambiguous sign of changing atmospheric structure," study co-author Bill Randel, a scientist at the National Center for Atmospheric Research in Boulder, Colorado, said in a statement. "These results provide independent confirmation, in addition to all the other evidence of climate change, that greenhouse gases are altering our atmosphere."
The troposphere is the layer of the atmosphere we live and breathe in. It extends from sea level to a height ranging from 4.3 miles (7 kilometers) above the poles to 12.4 miles (20 km) over the tropics. As the layer of atmosphere that contains the most heat and moisture, it's also where a lot of atmospheric weather occurs.
Air in the atmosphere expands when it's hot and contracts when it's cold, so the troposphere's upper boundary, called the tropopause, naturally shrinks and expands with the changing of the seasons.
But by analyzing atmospheric data such as pressure, temperature and humidity — taken between 20 and 80 degrees north latitude — and pairing it with GPS data, researchers showed that as increasing quantities of greenhouse gases trap more heat in the atmosphere, the tropopause is rising higher than ever before....
