We received the initial diagnosis way back in 1896 from Arrhenius....we were warned again in the 1920's and 1940's and 1950's and 1970's and 1980's and 1990's and 2000's and present day.
The greenhouse effect is not pseudo-science, it is fact and has been known as fact for centuries.
Carbon Dioxide (and other greenhouse gases) have been known for the same length of time.
The deception is being laid bare now in ways that are too significant to hide and soon too catastrophic to deny. We have been in the midst of the next great mass extinction event for perhaps up to the last 50 years as indigenous species around the globe have been being absolutely decimated and driven to extinction.
The glaciers retreat was a clear sign...ignored.
Mass frog extinctions was a clear sign...ignored.
Permafrost release of methane was a clear sign....ignored.
Rising Arctic temperatures was a clear sign....ignored.
Climate scientists around the world warned of this for DECADES now...ignored.
Climate pacts were agreed to and then the USA "pulls out", thus further ignoring the issues...
Bend over and kiss you ass goodbye folks. The data and projections we have been allowed to see were always low end estimates and best case scenarios...we were not shown the true horror for fear of creating the inevitable - global social breakdown, resource hording and war.
Shit is about to get real at long last. No one is ready for this....not even close.
