James Hansen’s new thoughts on State of Climate Science, GISS research, and Grave Threats we face…

I consider that James Hansen is the most important, prolific, significant, correct, climate scientist alive today.

I have been extremely fortunate to meet him at many UN yearly climate conferences (COPs - Conference of the Parties) over the years, and even chat with him during some of the UN side events with Climate Emergency Forum. He has appeared several times on our Climate Emergency Forum weekly videos.

I have often said that you really do not want to miss any of his comments or papers. I chat about his latest thoughts posted in an article on his Columbia website.

I also chat in this video about Canada's very own David Suzuki, and his recent interview. Again, I have been fortunate to meet him on several occasions, most notably at the front of one of Canada's largest climate change marches.

Contrasted with the work of these two great guys, I chat about some of the extremely bizarre and dangerous conspiracy theories floating around. Many climate deniers are going through literal contortions trying to explain off extreme weather events as being due to anything but fossil fuel burning GHGs.

Oh, what a world we live in, at the moment. Truly dystopian...

iPolitics article on David Suzuki interview:
‘It’s too late’: David Suzuki says the fight against climate change is lost

“We have failed to shift the narrative and we are still caught up in the same legal, economic and political systems,” said David Suzuki in an exclusive interview with iPolitics. “For me, what we’ve got to do now is hunker down.”

Sahara Desert Greening in AHPs (African Humid Periods) in the Paleorecords - what is going on today? I chat about periods in the paleorecords when the Sahara was green. Although we are seeing some greening in parts of the Sahara today from extreme precipitation events and planting of The Great Green Wall, we are not seeing an overall shift but are still getting an overall increase in desert area.

Over the last hundreds of millennia, natural rhythms in Earth’s astronomical motions triggered largescale climate changes and led periodically to humid conditions in much of northern Africa. Known as African Humid Periods (AHPs), such times sustained vast river networks, vegetation, wildlife, and prehistoric settlements. The mechanisms, extent, and timing of the changes remain poorly constrained. Although AHPs along glacial cycles are recognizable in marine sediment records, the related land cover changes are difficult to reconstruct due to the scarcity of proxy data over the continent. Moreover, most available information covers only the latest AHP during the Holocene. Here we use a comprehensive Earth system model to look at additional, much earlier, possible cases of AHPs. We simulate the full last glacial cycle, aiming to reproduce the last four AHPs as seen in available proxies. The simulated AHPs seem in broad agreement with geological records, especially in terms of timing and relative strength. We focus on the simulated vegetation coverage in northern Africa, and we detect a dominant change pattern that seems to scale linearly with known climate forcing variables. We use such scaling to approximate northern African vegetation fractions over the last eight glacial cycles. Although the simple linear estimation is based on a single mode of vegetation variability (that explains about 70 % of the variance), it helps to discuss some broad-scale spatial features that had only been considered for the Holocene AHP. Extending the climate simulation several millennia into the future reveals that such (paleo-based) pattern scaling breaks when greenhouse gases (GHGs) become a stronger climate change driver.

It is thus vital to understand its robust response to global warming. However, previous studies are merely focused on using a simple precipitation threshold as the definition criterion to estimate the varying size of the Sahara Desert. In addition, significant uncertainty in precipitation projections also limits relevant investigations of the Sahara’s future responses. Here, by developing an ensemble Bayesian discriminant analysis approach, we could provide an objective basis for desert identification under large inter-model uncertainty. Further, we find significant northward shifts of both the Sahara and the Sahel, which may induce higher risks of drought over the northwest of North Africa.
