The Not-So-New Climate Economy Report

An alliance of the most influential global institutions, including the UN, World Bank, IMF and OECD, just issued a report of the Global Commission on the Economy and Climate, chaired by Felipe Calderón and Nicholas Stern. The report’s title is Better Growth, Better Climate: The New Climate Economy. In a nutshell, it says that not only is climate action compatible with economic growth, but the two may actually work as a positive feedback loop: more climate action leading to more growth, “smart” growth-spurring policies reducing emissions of greenhouse gases. By and large, the report does not contain any new arguments, as it is more of a synthesis of existing research. Alas, it is a synthesis of only a part of existing research, which can be already seen in the title: economic growth is a main objective along with the mitigation of climate change. You’ll vainly look for any reference to the degrowth and a-growth debates, and so the report, while valuable in some respects, reproduces many of the common errors of growth-enthusiasts.

Talking About Green Jobs Might Impede Action on Climate Change

Advocates of true action on climate change do not have an easy job to do. Scientists keep producing evidence of dangerous man-made climate change, the IPCC keeps producing reports that summarize that evidence, activists keep doing their activism… Meanwhile, politicians, and decision-makers more generally, keep talking and the society at large sticks to business-as-usual. No wonder that the “alarmists”, as we are sometimes called, are steadily looking for new powerful arguments. In hope either that a specific single argument will suddenly make people wake up and act on climate change, or that the accumulated mass of arguments will do. One such argument is about so-called “green jobs”. Clean technology investments are presented as a great opportunity to create jobs, as a growth booster. However, in this specific case, the well-intentioned pro-climate-action argument might actually be a shot in the cause’s foot. Continue reading

Emissions Trading and Feed-In Tariffs: Do We Need Both?

When I started this blog some 3.5 years ago, the focus was on climate issues, particularly climate economics. More recently, however, I have neglected this topic a little. Fortunately, working at a research institute gives one the opportunity to learn a lot about things other scientists do–e.g., regarding the quite popular question whether the EU needs both emissions reduction and renewable energy deployment targets such as the 20-20-20 target. In other words: do we need an energy mix consisting, e.g., of emissions trading and feed-in tariff schemes? Or is emissions trading enough to reach policy goals? And, by the way, what are these goals? Continue reading

Nuclear Power or Fossil Fuels?, Revisited

More than two years ago I wrote here a piece about nuclear power. I critisized in it a commentary authored by Bjorn Lomborg, who argued that nuclear power is the all-environmentally friendly energy source. Then, I replicated a “green dogma” and wrote that

first, we cannot but abandon both [nuclear power AND fossil fuels], and, secondly, it is not necessarily true that we cannot afford a switch to renewables.

I do not longer think this is true. While still not sharing Lomborg’s and others’ enthusiasm about nuclear fission, I view it as the lesser evil. Continue reading

What If We Are Wrong about Global Warming?

No, I do not intend to present some other “sweeping” Climategate-like “proofs” that all those climate scientists warning since the 1960’s that human activities influence the global climate have been wrong. Quite the contrary, to date, science tells us clearly that the Earth is warming and that we are those responsible. Moreover, it tells us that it is likely to keep warming unless we do something about it, and if we do not, the consequences may be very unpleasant. So, the title question is entirely hypothetical. Nevertheless, I still find it very interesting because climate science may be wrong. Continue reading

Climate Change and the Long Winter 2013

Where is the global warming? After a rather long and hard winter this year, many Europeans ask this question. The media have been spreading the terrible scenarios of a human-made global warming for years. But in Europe and many other parts of the Northern Hemisphere, in April there was still a lot of snow outside. Reason enough to become doubtful. Seemingly. Actually, however, the winter of 2013 is perfectly fitting the picture drawn by climate science. To understand why, we have to answer a few preliminary questions first. Continue reading
