The cyanobacteria have an extensive fossil record. The oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old!
Fossil Record of the Cyanobacteria - UCMP Berkeley
http://www.ucmp.berkeley.edu/bacteria/cyanofr.html
For the entire history of life on Earth there have been cyanobacteria photosynthesizing oxygen (O2). Even a small amount of O2 may have been enough to prevent much of the H2 from escaping to space.

Rising insurance costs may convince Americans that climate change risks are real
I used to have a lot of hope that insurance costs would drive better policy and it still might some.
But that was before I saw the state of Florida give homeowners guarantees for hurricane damage and CA pass laws to protect homeowners and PG&E from the cost of fires.

Climate change is man made but not the result of auto emissions...It's caused by the giant wind turbines that generate electricity ... The blades generate drag slowing the earths rotation reducing the air flow that cools the earth's surface....Judge Judy is an alternate judge on the US Supreme Court...Many famous rulings...

1 out of 10 thought that Judge Judy was a member of the Supreme Court.
Maybe 9 out of 10 were wrong.
New York's trial level courts are called the Supreme Court (every other state calls if Superior court) and the honorable judge was at one time a family court judge in Manhattan, so she was on the Supreme Court.

I don't know if this has been posted before, but Savory makes what appears to be an ironclad case for vastly increasing grazing herds around the world. This TED talk is absolutely worth your while, and aficionados of grass-fed beef will be cheered (sorry, vegans):

Bummer. I need to read some of the studies linked in those articles. So did Savory fabricate his reports in the talk? How do we explain the transformed landscapes that he presented using his techniques? Those were some very compelling images. Bogus?

Edit: Read the Sierra Club piece. The guy seems like something of a crank, although his method probably has value in the right context. The idea, though, that flat-out desert can be greened by butt-loads of cattle is false, of course. No amount of "grazing" can turn the Mojave into a grassy paradise. But there was something going on when we had roughly 30 million head of bison roaring across the landscape pre-Euros.

Global carbon emissions to hit record levels in 2018, scientists warn
According to the report, global carbon emissions from fossil fuel and industry are expected to grow by 2.7 percent from 2017 to 2018, meaning that the world will spew some 40.9 billion tons of the substance this year, up from 39.8 billion tons in 2017.
The spike in emissions comes as almost no growth had been recorded for the past last three years.
Fossil fuel emissions are estimated to rise this year by 4.7 percent in China, the world’s biggest carbon emitter, 6.3 percent in India, and 2.5 percent in the United States. The European Union (EU), however, showed a decrease by 0.7 percent this year.

As more water runs off the ice sheet, it drives sea level rise,
Yes all that water will go into the ocean and then sun will take it and make clouds, rain will fall everywhere and make crops grow everywhere and everyone will live happily ever after .....

I think the big thing that people are not seeing is the collapse of the oceans and what impact that would have. Once the ocean gets too acidic due to all the carbon we are dumping into it and add to it all fertilizer aka the nitrogen we are dumping into it and then add some more heat, you get a toxic mess. It will take the forms of red tides, algae, seaweed as the foreshadowing. Then everything collapses and all oxygen disappears. Anyone who has dabbled with a saltwater fish tanks knows the cycle and what happens when the nitrates build up too much. You can do a water change in a fish tank to reduce nitrates but who will do an Ocean water change before it collapses? Everyone thought the oceans were soo vast that it wouldn't happen but it is starting and this is what scares me the most. Forget about climate change, we won't be able to breath since most of our oxygen comes from the oceans. Global population is the blame. Whoever said that the Nitrogen cycle is the problem is correct. Carbon is just a side problem to our bigger problem.

Abrupt Warming - How Much And How Fast?
How much could temperatures rise? As the image shows, a rise of more than 10°C (18°F) could take place, resulting in mass extinction of man...

No one is really talking about "killing the planet" or the end of the world.
The issue is changing it very significantly, enough to change society as we know it, in which case the impacts and costs of adapting are more than the cost of reducing GHGs in the first place.
Punitive action is a good term for those who spew lots of GHGs imposing huge impacts on other people who don't.

Awakening the Horrors of the Ancient Hothouse — Hydrogen Sulfide in the World’s Warming Oceans
“Dead Cthulu waits dreaming…” H.P. Lovecraft
In the 1930s, pulp horror writer H.P. Lovecraft penned tales of ancient monsters called Old Ones that, if awakened, would emerge to devour the world. One of these horrors, Cthulu, lay in death’s sleep in his house called R’lyeh at the bottom of the Baltic Sea (Charles Stross) awaiting some impetus to disturb him from necrotic slumber (ironically, the Baltic sea bed contains one of the world’s highest concentrations of the deadly hydrogen-sulfide producing bacteria that are a focus of this article).
