Climate change: 'Hothouse Earth' risks even if CO2 emissions slashed

It may sound like the title of a low budget sci-fi movie, but for planetary scientists, "Hothouse Earth" is a deadly serious concept.

Researchers believe we could soon cross a threshold leading to boiling hot temperatures and towering seas in the centuries to come.

Even if countries succeed in meeting their CO2 targets, we could still lurch on to this "irreversible pathway".

Their study shows it could happen if global temperatures rise by 2 deg C.

1. I am convinced that we need to, in the next 10 years, do

geo-engineering to cool the planet artificially...

I do not have the solution in mind... but it is something we are going to need to do or we lose (along with innumerably other species of life).

2. I think it's our only hope.

Even the possibility of making a mistake messing with the climate is no match for what we're up against without taking the chance.

5. Absolutely! nt

6. There has to be some amount of geoengineering as part of the solution.

The problem is absolutely dire.

3. Already happening. Just outside my door

A forest fire threatens. Temps as high as 110 forecast here for later this week. This is in the northernmost state, Washington, albeit in the inland NW.

Winds, high temps, even Yosemite closed till further notice ... summer is now one emergency after another.

Nowhere to run.

4. Most important issue of our lifetimes!

Most serious issue being ignored by the media and most people. It's human's head-in-the-sand default denial.

The rate of human reproduction and standard of living must change now. Nature is crashing the front door.
