Where should we be at this time? Becoming not only carbon neutral, but carbon negative.
Where are we? Still increasing emissions to record high values... and now, since Bolsonaro took power (The most anti-science president in the entire history of Brazil), the destruction of our Nature basically got free from consequences. Bolsonaro is doing whatever he can to destroy the Ministry of the Environment. He literally proposed it to be extinguished, and since that caused a huge backlash from all parties, he felt it would be enough to assign an science denier to be the Minister. He is removing all the powers from IBAMA (The Brazilian equivalent of the EPA), said is going to forgive all the industries that illegally deforested huge regions, and spreading the lunacy that climate change is a communist hoax...

Looks like he's following the Trump Strategy for effectively eliminating troublesome agencies without officially ending them on paper.

I was reminded at the recent lecture on microbes and climate (but not addressed by the lecturer) about di hydrogen sulfide and the negative loop with regards to albedo.  Thanks Dr Lovelock for another discovery.

Hoping we'll have prepared some engineered microbes that can produce a few terratons of oxygen per year, if the entire rest of the ecosystem collapses.

Using sulfate aerosols to cause a global dimming is one proposed method of geoengineering. If I remember correctly, though, if you want sulfate aerosols (or precursors) to do anything to the climate you need to inject it into the stratosphere, otherwise it'll just come down as acid rain almost immediately.
Mooohn!

Do you realize how far away are we from getting ready to do this?

I think it will take massive crop failures and widespread food shortages before people realize how bad things are getting and by then it may be too late.

The ancient loop of di hydrogen sulfide is totally different than sulphates in the stratosphere. That system is well known and described foot only increasing albedo (mostly coastal) and as a ccn, irrigating those coasts.  It is also a huge contributor to sulfur in soil.

Dumping mass quantities of H2SO4 or SO2 willingly cut the global average temperature a degree or so.  And when we find the unintended consequenses so diabolic and stop, the temperature will rapidly increase to the level it would have risen without the modification.  Of course this will do nothing for oceanic acidification, glacial retreat or changes in oceanic currents (ups and downs included). 

Totally bad idea, IMHO

Are you talking about this? Then this might be of interest.

Probably true.

Still not a glimpse of any reasonable hope in the horizon.

Plants are being extinct 500 times faster than the natural rate. FIVE. HUNDRED. TIMES. FASTER.

Thanks for CLAW review.  I'll give it a more serious read soon.

It doesn't make this news any better but it seems that most of this extinction is not due to climate change but to human intervention, deforestation, logging, destruction of habitat.

A.k.a. we haven't really even started seeing what climate change can do to accelerate the process. The sixth mass extinction began long before the industrial age.

Here's a new one from the denialist crew. I've seen them pimp this several times over the last few days.

Glacier National Park glaciers are actually growing – officials quietly remove its ‘Gone by 2020’ signs
https://tinyurl.com/y23u25sj

So the NPS has probably been told to take down any signs about climate change by the Trump Administration and this is evidence that science is wrong.

Here's the best science from the article: "Teams from Lysander Spooner University visiting the Park each September have noted that GNP’s most famous glaciers such as the Grinnell Glacier and the Jackson Glacier appear to have been growing – not shrinking-since about 2010. "

Oooooooooooooookay!
