Thom Hartmann’s ‘Last Hours’ video negated by IPCC AR5

By Anthony Watts | Watts Up With That? | October 13, 2013

From The End is Near department comes this video documentary from lefty talk radio guy Thom Hartmann that claims we are on the verge of a “mass extinction” due to climate change. Only one problem; the IPCC says “no” to his scenario. Ooops.

From the YouTube description, bold mine:

“Last Hours” is the first in a series of short films that explore the perils of climate change and the solutions to avert climate disaster. Each subsequent film will highlight fact-based challenges facing the human race, and offer solutions to ameliorate these crises. The initial short film series will culminate in a feature film to be presented prior to COP21, the 2015 UN Conference on Climate Change in Paris.

An asset for the climate change movement, “Last Hours” will be disseminated globally to awaken modern culture worldwide about the various dangers associated with climate change.

“Last Hours” describes a science-based climate scenario where a tipping point to runaway climate change is triggered by massive releases of frozen methane. Methane, a powerful greenhouse gas, has already started to percolate into the open seas and atmosphere from methane hydrate deposits beneath melting arctic ice, from the warming northern-hemisphere tundra, and from worldwide continental-shelf undersea methane clathrate pools.

Burning fossil fuels release carbon that, principally through greenhouse effect, heat the atmosphere and the seas. This is happening most rapidly at the polar extremes, and this heating has already begun the process of releasing methane. If we do not begin to significantly curtail the use of carbon-based fossil fuels, this freed methane threatens to radically accelerate the speed of global warming, potentially producing a disaster beyond the ability of the human species to adapt.

This first video is designed to awaken people to the fact that the earth has experienced five major extinctions in the deep geologic past — times when more than half of all life on earth vanished — and that we are now entering a sixth extinction. Industrial civilization with its production of greenhouse gases has the ability to trigger a mass extinction; in the extreme, it could threaten not just human civilization, but the very existence of human life on this planet.

The world community and global citizens urgently need to chart a path forward that greatly reduces green house gas emissions. To take action and follow the pathway to solutions to the climate crisis, you can explore this website and you can also sign-up for future updates. Thank you.

It’s the old “methane emergency” meme again.

But here’s the problem.

Apparently Thom never got the memo from the IPCC AR5. Note the third and fourth items in Table 12.4 from the IPCC:

IPCC_catastrophe_table

Definitions for this table can be found in the section “TFE.5: Irreversibility and Abrupt Change” in the draft report. They say:

Abrupt climate change is defined in AR5 as a large-scale change in the climate system that takes place over a few decades or less, persists (or is anticipated to persist) for at least a few decades, and causes substantial disruptions in human and natural systems.”

But alas, IPCC says Clathrate methane release is very unlikely, and they have high confidence in that assessment. Permafrost doesn’t seem to be much of a problem either, as it doesn’t seem to have the potential for abrupt climate change.

Looks like Thom Hartmann will have to rework his video.

  1. A licensed mechanical engineer (retired) who has been researching this issue (unfunded) for 6 years has discovered what actually caused global warming and why it ended. The time-integral of sunspot numbers (with appropriate proxy factor) calculates the average global temperature trend since 1610. An overlay of average global temperature measurements shows the OSCILLATIONS above and below the trend that are the net effect of ocean cycles. http://conenssti.blogspot.com/ . Rational carbon dioxide change has no significant influence.
