Blog edited by Sam Carana, with news on climate change and warming in the Arctic due to snow and ice loss and methane releases from the seafloor.
During the past decades, the idea of acting to counteract the damage done to the ecosystem by humankind's activities has moved along at least two planning stages.
We have reviewed the first two chapters of the new book Limits and Beyond. The reviews can be found at The Yawning Gap (Chapter 1) and No More Growth (Chapter 2). In this post we take a look at the third chapter, written by Dennis Meadows, a co-author of the original Limits to Growth. Dr. Meadows reports that he has delivered over a thousand speeches to a very wide variety of audiences. In this chapter the author summarizes “19 of the most common questions, comments and objections” that he has received over the years. Some of his insights are as follows:
The book Limits and Beyond, edited by Ugo Bardi and Carlos Alwarez Pereira, provides a 50th anniversary review of the seminal report Limits to Growth (LtG). The following is from the back cover of the book. 50 years ago the Club of Rome commissioned a report: Limits to Growth. They told us that, on our current path, we are heading for collapse in the first half of the 21st century. This book, published in the year 2022, reviews what has happened in the intervening time period. It asks three basic questions:
A brutal heatwave that has enveloped parts of southern Asia since the end of April looks set to intensify, says the latest forecast from the Met Office. Nick Silkstone is a meteorologist with the Met Office’s Global Guidance Unit. He said: “Temperatures are expected to peak on Saturday, when maximum values could reach around 49-50°C in the hottest locations, such as Jacobabad, and the Sibi area of Pakistan.
Don't you stumble, sometimes, into something that seems to make a lot of sense, but you can't say exactly why? For a long time, I had in mind the idea that when things start going bad, they tend to go bad fast. We might call this tendency the "Seneca effect" or the "Seneca cliff," from Lucius Annaeus Seneca who wrote that "increases are of sluggish growth, but the way to ruin is rapid."
Which effects did the heat wave of summer 2020 have in Siberia? geologists compared the spatial and temporal distribution of methane concentrations in the air of northern Siberia with geological maps. the methane concentrations in the air after last year’s heat wave indicate that increased gas emissions came from limestone formations.
We at Sea Research Society's Environmental Affairs Department are very concerned of the melting permafrost terrain and methane clathrate deposits of the Arctic Ocean's sea bed (which are seeding Siberia's air once again with carbon-12). This is because Arctic Ocean's methane clathrates, methane (CH4) & carbon dioxide (CO₂) deposits are thought to be the world's largest reservoir of carbon.
What could bring down the industrial civilization? Would it be global warming (fire) or resource depletion (ice)? At present, it may well be that depletion is hitting us faster. But, in the long run, global warming may hit us much harder. Maybe the fall of our civilization will be Fire AND ice.
