  Intergovernmental Panel on Climate Change (IPCC) Report, September 24, 2019 The Ocean and Cryosphere (the icy part of our planet) in a Changing Climate A Summary of Important Findings Overall of course, climate change is astonishingly worse with every new report. This one is no exception. Polar and mountain ice are melting faster, the…

West Antarctic Ice Sheet Collapse: The Critical Path

By Abrupt changes, Antarctica, Climate Catastrophes, Greenland, ice sheet, ice sheets, Impacts, Oceans, Sea Level Rise, West Antarctic Ice Sheet

    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 rise news from NOAA in 2016 and 2017. What is…

New Evaluation of Climate Models Reveals Abrupt Changes Ahead of Schedule

By Abrupt changes, Drought, Extreme Weather, forest health, Forest Mortality, Greenland, Gulf Stream, ice sheets, Impacts, modeling, The Unexpected

  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 why it is that “ice cube melt climate science” is…

Abrupt Sea Level Rise Warning From NOAA: Paris Inadequate

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 of sea level rise research on emissions reductions and resultant…

Sea Level Rise Scenarios Starting to Catch Up With Prehistory

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 important pieces of the science being reported on, that are…

Climate Change: What Should We Do?

By Abrupt changes, Climate Catastrophes, Climate Policy, Climate Reform, CO2 Removal and Sequestration, Emissions Scenarios, Extinction events, forest health, Forest Mortality, ice sheets, Myths, Negative emissions, pine beetle, Scenarios, sequestration, What we can do

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) have great challenges as climate reform decision makers. If our…

Global Warming vs. Abrupt Change — What’s the Difference?

By Abrupt changes, Antarctica, Arctic, Glaciers, Greenland, Gulf Stream, ice sheets, modeling, Sea Level Rise, West Antarctic Ice Sheet

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 simply because the warming we are experiencing, and that is…

Sea Level Rise: IPCC Averages, Extremes From Latest Publishing, and Ice Sheet Collapse

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 to written grammar, rather than the statistical uncertainty of when,…

Warm Winter, Early Spring: Is Climate Change a Mixed Bag or are we Kidding Ourselves?

By Abrupt changes, adaptation, Antarctica, Beaches coastal, Climate Catastrophes, Climate Policy, Climate Reform, CO2, Deniers and Delayers, Drought, economics, El Nino, Emissions, Emissions Scenarios, Extreme Weather, forest health, Forest Mortality, Glaciers, Greenland, Gulf Stream, ice sheet, ice sheets, Impacts, in-depth and Popular Press, IPCC, modeling, Negative emissions, Oceans, pine beetle, Policy, politics, Psycho, Scenarios, Sea Level Rise, Shifting Ecology, West Antarctic Ice Sheet, Winter Weather

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 debate to rage encouraging doubt. The Clean Power Plan and…

NOAA — Ice Sheet Collapse in Our Time: Zero Warming Climate Solution

By Abrupt changes, adaptation, Antarctica, Arctic, Climate Policy, CO2, CO2 Removal and Sequestration, Emissions, Emissions Scenarios, Greenland, ice sheets, in-depth and Popular Press, modeling, Negative emissions, Sea Level Rise, Solutions, West Antarctic Ice Sheet

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 good news with climate change is very good indeed. The…

Saved They Say: Emissions Have Flattened — Climate Mirage

By aerosols, Antarctica, Climate Policy, CO2, CO2 Removal and Sequestration, Emissions, Fracking, ice sheets, Negative emissions, Sea Level Rise, West Antarctic Ice Sheet

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 amount of long-lived warming pollutants already emitted into our sky…

More on the Shutdown of the Gulf Stream

By Abrupt changes, Greenland, Gulf Stream, ice sheet, ice sheets, Impacts, Oceans

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 from melting ice plays a significant role in abrupt change….

West Antarctic Melt Rate has Tripled

By Antarctica, Glaciers, ice sheet, ice sheets, Sea Level Rise, West Antarctic Ice Sheet

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 in the map on the right). This could possibly be…

Greenland: Jakobshavn New World Speed Record, Hundreds of Deeply Incised Underice Valleys Beneath Outlet Glaciers

By Glaciers, Greenland, ice sheets, submarine channel, underice

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 new dimension to the increase of outlet glacier flow that…
