1. These are today's emissions and top emitters. We included this graphic for a reason. #SR15 washingtonpost.com/energy-environ… 2. As we put it, in order to hold warming to 1.5C, "overall reductions in emissions in the next decade would probably need to be more than 1 billion tons per year, larger than the current emissions of all but a few of the very largest emitting countries." @brady_dennis

1. Want to thank folks for reading my recent story about Esieh Lake, a strange lake in the Arctic that’s bubbling up lots of methane, and the scientists led by Katey Walter Anthony of @UAFairbanks, who are trying to plumb its secrets. washingtonpost.com/graphics/2018/… … #thread 2.Here, I’m hoping to share a little more about the story, and some photos and charts.

1. It's time to talk -- again -- about Totten glacier, East Antarctica. In size, it’s somewhere between California and Texas. Single-handedly, it could raise global sea levels by nearly 13 feet. They basically don’t get any bigger than this. agupubs.onlinelibrary.wiley.com/doi/epdf/10.10… 2. Every year, as part of its normal outward flow, Totten sends 71 billion tons of ice into the ocean (but it also gains much of this ice back through snowfall). That’s more than any other glacier in East Antarctica, which is itself the largest ice mass on the globe, by far.

1. The “Younger Dryas” was an exceedingly weird climatic era beginning around 13,000 years ago. And it could have something really important to tell us about the future. washingtonpost.com/energy-environ… 2. It’s weird because it’s an ice age throwback at the end of an ice age. The world was getting warmer, ice was melting – and then suddenly it wasn’t any more (in the Northern hemisphere, that is, and especially Europe).

1. In which I endeavor to convince you that a process you may not have heard of called “Atlantification” is a pretty big deal washingtonpost.com/news/energy-en… 2. Basically, the Arctic Ocean is weird. Well, so is the Southern Ocean, and in the same way, but let’s focus on the Arctic.

1. So in light of the really big news yesterday about Antarctic ice loss *tripling* in a decade, I wanted to further unpack what this means and why it is so significant. washingtonpost.com/news/energy-en… 2. As I reported yesterday, a major scientific assessment has confirmed that the continent is now losing 219 billion tons of ice per year from 2012-2017, and that is three times the ice loss for the period 2002-2007, or 10 years ago.

1. So a pretty big deal study about changes to hurricanes under global warming -- changes that have apparently *already happened* -- has just come out. My coverage here: washingtonpost.com/news/energy-en… 2. The original study, in Nature, can be found here nature.com/articles/s4158…

1. I wanted to add some additional notes this morning on why it is such a big deal that the U.S. and UK are jointly spending tens of millions to send some 100 scientists – and Boaty McBoatface! -- to study Thwaites glacier, Antarctica. washingtonpost.com/news/energy-en… 2. Basically, this is an urgent research mission to determine just how bad sea level rise in this century could get.

1. Much of the key climate news of late has been about sea level rise. It hasn’t been good. 2. On the one hand we have a reaffirmation of a key mechanism behind James Hansen's 2016 climate disaster study – stratification of the seas around Antarctica.

1. Just published a story on a high profile pair of studies in Nature -- both about the slowing of the Atlantic ocean’s circulation. Aka, the Atlantic Meridional Overturning Circulation or AMOC.

2.The studies are here nature.com/articles/s4158… and here nature.com/articles/s4158…

1. In 2016, standing atop Petermann glacier in far northwestern Greenland, I saw meltwater everywhere. Some of it was dramatic and dynamic, like this 2. In other places it was frozen and still, like this.

1. Seeing a lot of reaction to my story (with @StevenMufson) on Shell’s new “Sky” scenario report, outlining how the world could actually meet the Paris goals and produce net-zero carbon emissions by 2070 (and, negative emissions after that). washingtonpost.com/news/energy-en… 2. So a few further thoughts on this type of exercise and what we can learn from it.

A little over three years ago in February 2015, on my first trip to the Arctic, I took this photo of weak sea ice along the coast of the Chukchi Sea. (1; #thread) 2. This was at a time of year when sea ice was nearing its annual maximum extent, but it was oddly broken up right along the shoreline.

So have now done a series of articles about the hurricane-climate connection, reliving my 2007 book, Storm World, in the process. (1) 2. I’m going to recap them here and then suggest some additional thoughts/directions.
