Can the world be saved without geoengineering?

Can the world be saved without geoengineering? What is your view?


The Climate Plan includes the more effective and safe geoengineering methods as separate lines of action, next to emission cuts. There are discussions on this at the Climate Alert group. Feel encouraged to join in!

In the following videos, a number of geoengineering methods are discussed. The videos were recorded in Marrakesh, Morocco, at the time of the UN climate negotiations that were held from 7-18 November 2016. Stuart Scott interviews Peter Wadhams, Hugh Hunt, Matthias Honegger and Douglas MacMartin.













In the video below, Jennifer Hynes interviews Stuart Scott and his work, including on the
Nobel Peace Prize for Sustainable Development. From: extinctionradio.net January 2017.

In the video below, Paul Beckwith discusses some Carbon Dioxide Removal (CDR) ideas, adding that "climate rates of change are abruptly spiraling upwards. Although we must slash fossil fuel emissions, that alone will not restore climate stability. Like the proverbial roadrunner charging over a precipice and cratering, we have left things too late. We must also remove carbon dioxide from the atmosphere and/or oceans to have a fighting chance. I discuss several options to do this."



In the video below, Paul Beckwith is weighing Solar Radiation Management (SRM) options, adding that
"to have a fighting chance of arresting abrupt climate change we must deploy Solar Radiation Management Tech to cool our planet and buy us time to remove carbon dioxide from the atmosphere and oceans and slash human emissions. We have no choice. These technologies are not risk-free, but risks must be weighed against the near-certainty of collapse of global food supplies and geopolitical chaos."

Most Important Videos Uploaded In December 2016


Peter Wadhams is interviewed by Stuart Scott, Executive Director of United Planet Faith & Science Initiative, in this video called Farewell to Arctic Ice, uploaded December 27, 2016, and recorded at UN climate negotiations in Marrakesh, Morocco.


Peter Wadhams is an 'expeditionary' scientist and Emeritus Professor of Ocean Physics from Cambridge. Peter Wadhams' observations of the Arctic ice for over 4 decades makes him one of the worlds authorities on the subject.

In the video, Peter Wadhams discusses some of the issues described in his current book A Farewell to Ice (right), which is available as hardback or ebook (256 pages, published September 1, 2016).

Below is the sea ice volume image (created by Wipneus) that is discussed in the video.


Mark Jacobson gave a presentation called How the Future of Energy Impacts the Future of Our Cities, as part of the Digital Cities Summit, October 2016. The video was uploaded on 7 Dec 2016 by Stanford University School of Engineering.


Imagine a future where the entire U.S. energy infrastructure runs on clean, renewable energy. It’s possible to do it by 2050, says Stanford civil and environmental professor Mark Jacobson, and even without any new technologies. Mark Jacobson laid out the hidden upside of using solar, wind and water resources – rather than burning fossil fuels – to power everything from appliances and machinery to cars and building systems. “If you electrify everything, something magical happens. Without really changing your habits, you can reduce power demand by about 42%,” Mark Jacobson says.

Such a huge reduction in power demand comes mostly from the efficiency gains of electricity over combustion and eliminating the energy needed to mine, transport and refine fossil fuels. In addition to the pure energy savings, Mark Jacobson estimates that we could avoid 4 million to 7 million deaths from air pollution, eliminate $15 trillion to $25 trillion in global warming costs, create 17 million more jobs than would be lost if we don’t transition, and reduce the energy poverty of up to 4 billion people worldwide.

Paul Beckwith produced a two-part video, called 'Abrupt Climate Disrupting Arctic Changes'. The first part is at Part 1 of 2 and the second video, featured below, is at Part 2 of 2. The videos were uploaded on December 30, 2016.


In the videos, Paul Beckwith describes that gut-wrenching disruptions are underway in the Arctic, including record-high temperatures, near-record summer ice loss and spring snow cover loss, and record low sea-ice winter growth.

This second video is particularly interesting at the segment from 8:30 to 12:00 minutes, where Paul Beckwith discusses how wind patterns are changing over the Arctic and how this will make the Beaufort Gyre and other ocean currents reverse when we get complete sea-ice loss.

For more on this, see also the post Accelerating Warming of the Arctic Ocean.



Peter Wadhams also featured in this video interview by Jennifer Hynes for ExtinctionRadio, uploaded December 29, 2016.


There is also a shorter version of this interview, without music.

The interview is part of episode 62 at ExtinctionRadio.net, uploaded December 28, 2016. This episode also includes interviews by host Mike Ferrigan with Paul Beckwith and Tim Garett.



Guy McPherson gave a presentation at the Fayetteville Free Library in Syracuse, New York, on December 22, 2016. Part 1 is the presentation, featured below. Part 2 covers questions and answers, following the presentation. The videos were uploaded December 27, 2016.



Two images used in the presentation are added below.

An earlier presentation was given by Guy McPherson in Wellington, New Zealand. The presentation was given at Victoria University in Wellington and was streamed live at 6:00 p.m. New Zealand time on 6 December 2016. The video was uploaded on December 7, 2016.

Methane Monster II ~ Demise of the Arctic



Presentation by Jennifer Hynes on runaway feedbacks in the Arctic and the resulting threat of near-term human extinction. At https://www.youtube.com/watch?v=7zUUZAomj6E


There are links to the transcript and to the complete set of slides of the presentation at Jennifer Hynes' blog.

The Arctic Methane Monster's Rapid Rise


Researcher Jennifer Hynes recently gave a frightening presentation about the situation in the Arctic and the odds that things will rapidly spiral out of control soon, escalating into runaway global warming a few decades from now. 




Above, a slide from the presentation, warning about the danger of earthquakes causing methane hydrate destabilization (from: Smoke Blankets North America). As the map below shows, 77 M4+ earthquakes did hit locations around Greenland in the year 2014 up until August 4.


Below is Jennifer's presentation, also on youtube at youtube.com/watch?v=a9PshoYtoxo



The image below shows sea surface temperature anomalies in the Arctic at August 7, 2014.


Warm water is carried into the Arctic Ocean by the Gulf Stream, as illustrated by the image below.
[ click on image to enlarge ]
The image shows how the Gulf Stream brings warm water to the edge of the sea ice. Waters close to Svalbard reached temperatures as high as 15.6°C (60.1°F) on August 8, 2014 (green circle). Note that what the image shows are sea surface temperatures only. At greater depths (say 300 m), warm water is pushed through the Greenland Sea by the Gulf Stream. Since the passage west of Svalbard is rather shallow, a lot of this warm water comes to the surface there. The high sea surface temperatures west of Svalbard thus indicate that the Gulf Stream is carrying very warm water (warmer than 15°C) at greater depths and is pushing this underneath the sea ice north of Svalbard.

As said, the situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan blog at climateplan.blogspot.com and as illustrated by the image below.
