Story of the Week...

Seven charts show why the IEA thinks coal investment has already peaked

Global investment in coal-fired power plants is set to decline “dramatically” after passing an all-time high during the past several years, says the International Energy Agency (IEA).

That’s one of the most striking messages from World Energy Investment 2017, published today. The report, now in its second year, offers a comprehensive picture of energy investment from fossil-fuel extraction through to transport, energy efficiency and power networks.

The IEA report is not only backwards looking, reporting money already invested. It also offers a glimpse of forthcoming trends, by reporting the value of decisions taken to invest in future.

Overall, investment fell again last year, as the oil-and-gas sector continued to cut back in response to low prices. Steady investment in renewables, along with falling costs, saw 50% more capacity being added in 2016 than in 2011. But gains for low-carbon wind and solar are being offset by declines in hydro and nuclear.

Carbon Brief has seven charts with the key messages from this year’s energy investment report.

El Niño/La Niña Update

The latest ENSO forecast by CPC/IRI is holding steady since last month and favoring ENSO-neutral conditions (50-55% chance) into the winter of 2017-18. Although not favored, El Niño development has an elevated chance of occurring (~35-45%) relative to the long-term average (~25-35%), so we still need to keep our eyes on this possibility.

Climate Feedback Reviews...

Climate Feedback asked its network of scientists to review the article, Nearly All’ Recent Global Warming Is Fabricated, Study Finds by James Delingpole, Brietbart News, July 9, 2017.

Seven scientists analyzed the article and estimate its overall scientific credibility to be 'very low'. A majority of reviewers tagged the article as: Biased, Inaccurate, Misleading.

Review Summary

This Breitbart article by James Delingpole claims that the observed warming of Earth’s surface temperatures is largely a fabrication by scientists who have altered the measurements. The source for this claim is a document written by three individuals who have no track record of publishing scientific research on the topic, and have not submitted their work to peer-reviewed scientific journals, but simply uploaded a pdf on a wordpress blog.

Scientists who reviewed the article found that its claims are false and misleading. Data are indeed adjusted to accurately account for things like changes in the instruments used to make measurements or the relocation of weather stations. However, the impact of these adjustments on the global temperature record is actually small, and the warming trend of the last century would appear to be larger without the adjustments, in contradiction with the claims in the Breitbart article.
