Rachel Carson’s landmark book “Silent Spring” was published in 1962. It, alone, of the important environmental best-sellers of that era, had a significant impact: it led to the banning of DDT (at least in the Western world) and major shifts in agricultural practice.
Paul Ehrlich, a noted American biologist, best known for his warnings about the consequences of population growth and limited resources, was the author of a famous book “The Population Bomb” (1968), in which he claimed (as Malthus had claimed in 1798) that increasing population – demographic catastrophe — would inevitably outstrip food and resources, and that hundreds of millions of people would starve to death in the 1970s.
Everything you always wanted to know about global warming. But were afraid to ask.
Most carbon emissions are absorbed by the ocean, but it’s running out of capacity, which could make global temperatures rise even faster.
The bottom line is that there is no alternative non-anthropogenic theory to explain rising temperatures, melting glaciers, sea level rise and ocean acidification. If we don’t act, the existing mechanisms of the climate will only reinforce the damage already done.
A Dangerous Crack in Economic Theory:
Why growth is slow and world trade is not always win-win.
As Larry Summers and many other economists have lamented (and even Donald Trump has said in several campaign speeches), it is true that the global recovery from the financial collapse of 2008 has been extraordinarily slow. Explanations vary widely. My own explanation up to now has focused on the shift from growth based on the exploitation of natural resources (especially oil and gas) to growth based on ICT technologies incubated in Silicon Valley but employing very few people. Another explanation centers on the working class reaction (in the US) to globalization and “free trade deals” favoring the export of manufacturing jobs to low wage countries.
A related explanation centers on the rise of the financial industry, along with its preference for moving money into the creation of asset bubbles rather than investment in small businesses in the “real” economy. A cousin of this explanation is that the money available for investment by the richest few is increasingly devoted to increasing the power of money in the political process. There is probably some truth in each of them.
The end of the era of increasing debt, with near zero interest rates is coming very soon. When it does, the cost of those deficits will explode, and the pressures for a major revolution in economics, capitalism and democracy, will also explode.
Scientists are closer than ever to definitively proving that climate change exists and putting the deniers to rest. Despite the recent climate agreement in Paris (COP21), where 195 countries adopted the first legally binding treaty to curb climate change, the debate about whether climate change exists or whether it’s the fault of human beings still rages on.
The first article in a three-part series, originally based on an interview, followed by a publication in “INSEAD Knowledge”. I undertook it, at first, to compensate for the influence of certain climate deniers on the faculty and among the readers.
See “On EROI, as a measure of what’s left in the barrel” at http://wp.me/p55vqx-95
Happy to see a website devoted to the (mostly) good ideas of Robert Ayres. As the originator of the term if not the concept of EROI I would like to clarify a few things from my own perspective. The energy invested is usually and appropriately considered the energy diverted from society to get energy to society. Thus natural gas used to pressurize an oil/gas field or energy used in society to make a drill bit or oil rig or fertilizer for corn-based ethanol would be considered part of the investment. Geological energy to make radioactive uranium or oil would not.
