Climate Letter #1393

An opinion piece by Michael Mann about the Republican Party’s climate change dilemma, published by Newsweek.  The party’s strategy has mostly turned from denial to delay, but anything more would require a clean break with the fossil fuel industry that provides much of its funding.  “Fortunately, it seems that GOP climate denial may be starting to thaw, as they evolve from a party of outright denial to one that at least pays lip service to solutions. The only question is which will melt first, Republican denial and delay, or the polar ice caps?”

David Roberts, who frequently writes about climate change for Vox, takes a somewhat more combative stand toward Republican obstructionism.  He sees climate change as a catastrophe in progress that requires a radical change in the status quo.  He concludes with:  “Enacting sweeping reform, in the face of a US political system heavily weighted in favor of the status quo, requires a groundswell. A popular mandate. And that in turn requires an agenda that can spark the public imagination and pull in apathetic and infrequent voters. Policy that is designed not to bother anyone won’t do that.”

A British professor of ecological sustainability makes observations about the carbon emissions attributed to the Earth’s richest people (The Conversation).  Using statistics provided by Oxfam, he argues that the root of the problem does not lie with overpopulation, or with nations, but with a specific class of people.  This same group has more than ordinary access to control over lawmakers and lobbyists.

A retired professor of horticulture believes almost everyone could cut back on purchases of consumer goods (Yale Climate Connections).  That is truly an easy way to shrink one’s carbon footprint, and perhaps do even more for personal well-being.  “In reality, according to historian David Christian, many components of a good life – friendship, empathy, kindness and generosity, good conversation, an appreciation of beauty, a sense of physical well-being and security, a sense of contentment, a sense of intimacy, a sense of humor, and a delight in good ideas – require no consumption and are “renewable resources” that emit no greenhouse gases.”

Loss of ocean oxygen  had a central role in an early mass extinction.  The cause of the extinction that took place 430 million years ago has long been a mystery.  “Now, for the first time, a Florida State University team of researchers has uncovered conclusive evidence linking the period’s sea level rise and ocean oxygen depletion to the widespread decimation of marine species.”  The study found that “you don’t necessarily need the entire ocean to be reducing to generate these kind of geochemical signatures and to provide a kill mechanism for this significant extinction event…..Today, like 430 million years ago, sea level is on the rise and ocean oxygen is hemorrhaging at an alarming rate. As parallels continue to emerge between today’s changes and past calamities, peering into the Earth’s distant past could be a critical tool in preparing for the future.”
