Chapter 3. Converging CrisesClimate

Morton (2013). Hyperobjects. Philosophy and Ecology after the End of the World.

Morton, Timothy. Hyperobjects. Philosophy and Ecology after the End of the World. Minneapolis: University of Minneapolis Press, 2013.

Summary:

Global warming is fundamentally different from many other threats we as humans have faced. We are actually inside this threat; we are part of it and responsible for it. Dealing with global warming is therefore utterly difficult. Right now we are in denial – which is logical because the danger is really coming from unusual dimensions (a hyperobject). We should pause to see it, and then take responsibility.

Opinion:

As a work of philosophy, this book offers new and original ideas. As a practical guide to living in times of hyperobjects the book takes way to many words to describe what has been summarized above in five sentences. Morton is bold and graceful, however, in his use of art and artworks to construct his argument, and pointing out a role for the arts in communicating the intricate world of hyperobjects into the realm of our unconsciousness.

State of the Climate

Since the beginning of the Industrial Revolution, CO2 levels have increased 40% and methane levels over 250%.

Greenhouse gasses have the effect of preventing heat leaving the planet. Over 90% of the extra trapped heat is absorbed by the oceans.

Global temperatures have risen 0,8C in the last century.

The Arctic ocean is losing ice at about 3000M3 per decade since 1979. Back then there was about 17,000 cubic meters of Arctic ice in September (just after northern summer). If the trend continues then it takes only 17,000/3,000 = 5.6 decades since 1979 before the arctic will be free of ice in summer. In about two decades, in 2034 the Arctic might be free of ice. Given the variance, it will probably occur somewhat sooner.[1].

The Arctic is warming up more rapidly because ice reflects heat (albedo) much better then water. This extra warming of the Arctic region, called Polar Amplification, is currently the largest positive feedback in the climate system.

A second albedo change comes from darkening of the snow cover, due to black sooth from increasing forest fires and old particles that emerge from the melting snow, collecting in the top layer.

Methane eruptions in the Arctic are increasing because of the heating Arctic. Russian scientists Nathalia Shakova and Igor Semiletov estimate that methane clathrates (gas molecules frozen in water) in the shallow ocean north of Siberia can be destabilized in a matter of decades, saying “It might happen today”.

Feedback loops like albedo and methane clathrates have the potential of leading to an abrupt change in global climate.

Sea levels rising indicate rising temperatures, because two sources contribute to sea level change: water temperature and melting land ice.[2]. Projections of sea level rise are uncertain, because the feedback loops seem to be highly unpredictable. Estimates for ‘business as usual’ range from about 1 meter by 2100 [3] to about 7 meters by 2070[4]. The last number is based on Paul Beckwiths observation that glacial melt rates have been doubling about every 7 years in the last few decades.

Extreme weather events are increasing rapidly. For people in coastal regions, like Miami, Bangladesh or the Netherlands, that means it will be even more difficult to keep the rising water out. The 90% of extra warming energy going into the oceans means more energy for storms and tornadoes is available. Other areas face increased drought, heat or cold.[5]

Arctic Methane and the Mind

In the chaotic process of global warming, methane release from permafrost is a wildcard. The possibility of a sudden release of huge quantities of methane seems to be increasing. Russian researchers Igor Semiletov and Natalia Shakova have found indications of increasing methane release off the coast of Siberia. If such a sudden release were to happen, a mass extinction event on earth is likely.

This is a short video, “Arctic Methane and the Mind” showing some evidence and questioning the way the human psyche deals with this intangible news.

 

Why Climate Change is Happening and Catastrophic

For the first time in human history we are altering the climate of the planet in a way that is threatening our own subsistence. Global warming can make the Earth uninhabitable – at least for the nine billion people that could be alive halfway the current century, and certainly for the poorest part.

The climate crisis is interlinked with other crises. Biodiversity is threatened by global warming because forests can’t cope and die, taking the animals for which they are the habitats with them.[1] Floods, droughts, hurricanes, rising seawater levels and disappearing glaciers affect the poor in developing countries the most, so social inequality is increased as well.
