The science blog Phys.org writes about the heat wave over all Europe, from London to Siberia. There have been heat wave deaths already in California and New Mexico. You know some flights out of Phoenix Arizona were canceled, because the heat was too intense to allow some planes to fly. There were three record hot days in Phoenix, reaching 117 degrees Fahrenheit on June 20th, which is over 47 degrees C. The overnight low, and this is key for human survival, was over 90 degrees C, or 32 C. Thats relentless heat.
.....
In perfect timing, our recent Radio Ecoshock guest Camilo Mora, of the University of Hawaii, with 17 other scientists from several countries, published a new study in the journal Nature Climate Change. The title is Global risk of deadly heat. Seth Borenstein, the reliable reporter from Associated Press, gives it this headline: Too hot to handle: Study shows Earths killer heat worsens. The study says 20 percent of humans already experience 20 days a year of deadly heat. By the end of this century, unless dramatic action intervenes, three out of four humans will live, or die, through that heat. Its planetary heating. Lets call it global warming.

The change that is on the way is going to blow right past the 2C mark and it is going to be catastrophic. Even if we stopped burning all fossil fuels today...right now.
The current CO2 PPM (400+) in the atmosphere is at a number not seen in hundreds of thousands of years...if ever (icecores going back 800,000+ yrs have no record of 400+) since life on Earth formed...and we still have the methane (which is 4x the greenhouse gas CO2 is) in the premafrost to come.

(1,526 posts)It is rated at 15x to 20x CO2 over 100 years. But in the first year or two it is more than 150x CO2.
I heard a figure today that atmospheric methane was being measured now at 2ppm (vs CO2 at 410ppm). But with its awesome heating effect that is like adding 200 to 300ppm CO2 equivalent on top of the actual CO2.
yep, were cooked.

(28,120 posts)When the executives of the big corporations owning the networks cannot fly to their summer homes/ getaways because the airports are closed, as happen in Phoenix recently?
There are things that can postpone the terminal diagnosis of the planet for a wee bit....but, yeah, most all life here is certainly terminal.
People having babies now are insane.
