  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…

In an Age of Climate Change, Even Titanic II Is Not Safe From Icebergs Bruce Melton First Published on Truthout November 13, 2018 Titanic II is set to sail in 2022. It’s a $500 million replica of the doomed Titanic that hit a North Atlantic iceberg in 1912. A local news report about the new ship postulated…

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…

Sing Delay, Delay, Delay: 0.5 C Limit to Dangerous Climate Change

Sing Delay, Delay, Delay When serious discussions about global warming gases and fossil fuels began in the 1980s, all that was needed to prevent what would become labeled as dangerous climate change was a reduction of the emissions of global warming gases. Since that time, we have emitted as much CO2 as we emitted in…

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…

Ice Loss During Antarctic Cold Reversal May Spell Trouble for WAIS Collapse

By Abrupt changes, Antarctica, Glaciers, Greenland, Gulf Stream, ice sheet, Oceans, underice, West Antarctic Ice Sheet

Fifty-two feet of sea level rise occurred in 400 years, 14,500 years ago with ocean and collapse conditions similar to today. We were coming out of the last ice age then, but then, forcing was thousands of times less than today. Our climate’s most meaningful and common changes are classified as abrupt changes in climate…

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

By Abrupt changes, adaptation, Antarctica, Climate Policy, Climate Reform, CO2 Removal and Sequestration, Extreme Weather, global warming psychology, Greenland, Gulf Stream, ice sheet, ice sheets, Impacts, Legacy Policy, Messaging, Negative emissions, Policy, Psycho, Sea Level Rise, Solutions, Strategy, West Antarctic Ice Sheet

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,…

Ice Waves — Increased Greenland Ice and Melt Discharge Waves from 2010 and 2012

By Greenland, ice sheet, Impacts, Sea Level Rise, underice

Ice Waves — The most fantastic climate science of last week (that crossed my desk): This work evaluates  a new discovery of melt waves of increased ice and water discharge in the Greenland melt years of 2010 and 2012. At one glacier (Rinks,) the peak monthly increased ice and water discharge was about equal to…

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

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

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…

First published on Truthout December 26, 3015, by Bruce Melton. Climate science is way out in front of climate policy. Commitments at the United Nations Climate Conference in Paris pale in comparison to those from the Kyoto Protocol with its beginnings in the Rio Earth Summit in 1992. The cheap and unambiguous solution of removing CO2…

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….

There All Along: “Exceptional” Slowdown of the Gulf Stream From Greenland Melt

By Abrupt changes, Arctic, Glaciers, Greenland, Gulf Stream, Oceans, Truthout.org

First Published on Truthout, April 13, 2015. The Gulf Stream plays an immensely important role in moderating the climate of eastern North America and Europe. Moreover, Greenland melt impacts ocean current processes in the North Atlantic. For years, contradictory research has alternately said the Gulf Stream was slowing and that it was not slowing. The…
