West Antarctic Ice Sheet Collapse: The Critical Path Article link Sea level rise estimates of around 10 feet by 2100 are now becoming hard to ignore. This article is about several new findings in 2018 that build on near-10 feet of sea level…
New Evaluation of Climate Models Reveals Abrupt Changes Ahead of Schedule It’s not the averages that will mess up your hair, it’s the gusts. This work on modeling the unmodelable (Drijfhout 2015) is a couple of years old now, but it gives enormous insight into…
NOAA’s new sea level rise report in January 2017 is a dope slap that describes 17 inches of sea level rise in Florida by 2030. You can see the report here, or check out our review that summarizes the important parts here. The continuing publishing…
McClatchy reported on a new NOAA sea level rise impact report and made some very good points. But a lot of the true meaning is left out. I like to use well publicized journalism like this to be able to quickly get to the most…
One of the biggest myths about climate change is that emissions reductions cool Earth. This is nowhere close to reality. Even the Paris Commitments of 80 percent emissions reductions by 2050 allow warming to triple by 2050 and quintuple by 2100. We (the royal we)…
Scientists may not be able to tell if this calving event was caused by climate change or not because of the constraints of certainty in science, but engineers have different risk/certainty assumptions that allow a better understanding of the reality of climate impacts on ice…
Something that is not clear in the overall climate discussion is that global warming is a radically different beast from abrupt change. We hear abrupt change bandied about, but often it is not well defined. It appears to many that global warming is abrupt change…
It’s not the averages that are troublesome. The understating reporting of scientists, journalists and climate science consensus organizations is one of the most confounding parts of climate change today. It’s the extremes that matter, yet extremes are viewed as “uncertainty” in a way almost entirely related…
President Trump it seems, has given us permission to backslide with our thinking about climate change. Until we have rule or law that tells us we must do something about climate pollution, “those that would rather it not be real” have won. This allows the…
We have delayed too long and now must urgently reduce the load of warming gases already emitted to our sky. We have been warned this would happen for decades, we just didn’t think it would happen so soon. This is exceedingly bad news, though the…
And they also say that Elvis is not dead. But alas… the answer is no, we are not saved. Things are actually getting worse because of the so-called “flattening emissions.” This needs to be said over and over: the only way to treat the vast…
Dansgaard Oeschger climate variability, more easily remembered as abrupt climate change, has been known from across the world through numerous lines of investigation since the early 1990s. This research greatly increases the robustness of the theory that a freshwater cap in the far North Atlantic…
Our previous understanding of how the Antarctic Ice Sheet responded to warming at the end of the last ice age 10 to 20 thousand years ago was based on only a few ocean sediment cores. From sediment cores in the North Atlantic we have been…
The Gulf Stream may not actually shut down, but it is slowing now and has been for some time (see here) and these researchers have come close—if not having actually solved—the puzzle of why the Gulf Stream slowed or shut down in the past and…
The Arctic is warming on average twice as fast as the global average, but in places the warming is double even this rate. Implications are immense as the Arctic is literally the worlds air conditioner, or at least most of the world as most of…
Work from Leeds, Durham University, the Byrd Polar Research Center and University of California, Irvine, have taken a deeper look into melt lakes forming on the Greenland Ice Sheet. There modeling was for melt lake formation in the melt zone. The “melt zone” is that…
Researchers at UC Cal Irvine and NASA, using four different measurement techniques, have found that West Antarctica’s ice loss has tripled since 1992. The measurements looked at glaciers discharging to a west central location of West Antarctica called the Amundsen Sea Embayment (see Amundsen Sea…
This research, funded by the Swiss and U.S. National Science foundations, looked at Greenland Ice Sheet movement in the melt zone that extends inland 50 to 100 miles from the edge of the ice sheet. This is where melt water moves through the crevasses in…
The North Atlantic is warming and Greenland’s ice loss has quadrupled in the last 20 years. Warm water is getting under the floating edges of outlet glaciers and causing thinning which in-turn causes the glaciers to speed up. New research has identified another and possibly…
