If the patterns observed during the Holocene hold for current anthropogenically forced warming, the weaker latitudinal temperature gradient will lead to considerable reductions in mid-latitude water resources.From the press release: "We found that when the Arctic warms, resulting in smaller temperature differences between the Equator and the pole, the jet stream gets weaker and less precipitation falls in the mid-latitudes."
“Everything is changing about the natural world and everything must change about the way we conduct our lives. It is easy to complain that the problem is too vast, and each of us is too small. But there is one thing that each of us can do ourselves, in our homes, at our own pace — something easier than taking out the recycling or turning down the thermostat, and something more valuable. We can call the threats to our future what they are. We can call the villains villains, the heroes heroes, the victims victims and ourselves complicit. We can realize that all this talk about the fate of Earth has nothing to do with the planet’s tolerance for higher temperatures and everything to do with our species’ tolerance for self-delusion. And we can understand that when we speak about things like fuel-efficiency standards or gasoline taxes or methane flaring, we are speaking about nothing less than all we love and all we are.”Last year the NY Times Magazine had this article by Rich, based on his book: Losing Earth: The Decade We Almost Stopped Climate Change. It's about there period 1979-1989. I'm a little dubious, but it's an article worth reading.
The start of a solar grand minimum is anticipated in solar cycle 27 ± 1 in 2043 ± 11 and the beginning of phase of deep cooling in the new Little Ice Age in 2060 ± 11.I wonder if he's taken into account his failed prediction of 2012....
...incorporated a host of improvements in their next-generation model. It mimics the ocean in fine enough detail to directly simulate eddies, honing its representation of heat-carrying currents like the Gulf Stream. Its rendering of the El Niño cycle, the periodic warming of the equatorial Pacific Ocean, looks “dead on,” says Michael Winton, a GFDL oceanographer who helped lead the model's development. But for some reason, the world warms up faster with these improvements. Why? “We're kind of mystified,” Winton says. Right now, he says, the model's equilibrium sensitivity looks to be 5°C.Models from ETH Zurich, CCCM in Canada, GFDL and NCAR are all running hot. CMIP6, the Climate Model Intercomparison Model, where models all run the same scenarios and compare results, may sort out the issues, but it's running late, impacting deadlines for the first drafts of the 6AR.
In assessing how fast climate may change, the next IPCC report probably won't lean as heavily on models as past reports did, says Thorsten Mauritsen, a climate scientist at Stockholm University and an IPCC author. It will look to other evidence as well, in particular a large study in preparation that will use ancient climates and observations of recent climate change to constrain sensitivity. IPCC is also not likely to give projections from all the models equal weight, Fyfe adds, instead weighing results by each model's credibility.The IPCC 6AR is scheduled to come out in 2021.
"If you’ve been following climate news, you’ve probably heard about an approaching “tipping point” toward climate change — the point of no return after enough small changes brought us to certain disaster."The truth is, there is no such tipping point!

Also a reminder of the amount of CO2 it emits. What you see is water vapor, and for every molecule of water, there’s roughly one molecule of (invisible) CO2 as well.
Imagine all our CO2 emissions were visible! https://t.co/ktZIHxrc2E
