SunEdison, one of the world’s largest renewable investors, has warned subsidy cuts will kill solar in the UK after Mark Group, a solar and insulation installer it had recently bought went into administration, reports the FT. The Telegraph says 1,000 jobs will be lost as two solar and insulation firms lay off staff. Solar job losses could reach 27,000 — ten times higher than at the Redcar steelworks — says theGuardian. Both solar firms to close this week blamed government cuts, says the Independent. Business Green asks if the solar industry will survive 2016. In a second article it says the government has defended its planned cuts. A third article says 3 gigawatts of onshore wind could go ahead despite an early end to another subsidy scheme. New Scientist says the government could face legal action over its “climate failures”. The Guardian explains what consumers need to know about the solar firm closures. Each of the two firms’ demise is reported by the Guardian (second closure) and Business Green (second firm).

Corals around the world are being bleached by warming oceans, combined with the warm El Niño Atlantic weather pattern, reports AP. One scientist tells AP that 10 to 20% of corals could be lost this year, calling it a “crisis”. Another tells Nature “we’re in shock and awe”. It says the previous largest-ever bleaching event saw 16% of corals die in 1998. Dot Earth explains what can be done to limit impacts. This is the third global bleaching event, says Climate Progress. The Guardian explains why we should all be worried, quoting a marine ecologist’s view that this could be “the biggest global biodiversity disaster since the last mass extinction”. The global bleaching event was declared by the US National Oceanic and Atmospheric Administration on 8 October. Fox News and Climate Central also carry the story.

Rich nations are contributing around $57bn a year in climate finance, according to a study by the OECD, reports the Financial Times. The figure — short of a $100bn annual target for 2020 — is likely to face close scrutiny, the paper says. A group of 20 climate-vulnerable nations have formed a “V20” group to press for more action, reports Reuters. A second FT article reports claims that “fossilist” financial markets have a hidden unintended bias towards unsustainable investment. Separately, the European Investment Bank stands accused of exaggerating its climate efforts, reports Business Green. Meanwhile Christine Lagarde, IMF chief, is calling for governments to back carbon pricing at a meeting of finance leaders in Peru, report Climate Home and Climate Progress. Business Green says oil giants are next week due to renew their backing for carbon pricing. The group of up to 10 oil and gas firms will pledge to tackle climate change through “cleaner” fuels, says the Financial Times.

China has raised its solar installation target for this year by 30% says Reuters, citing state media reports. The increase would see the previous goal of 17.8 gigawatts (GW) raised by another 5.3GW, it says, with 7.7GW added in the first six months of the year. China needs to spend $315-$630bn each year on green investments, says its central bank deputy government, according to a separate report from Reuters.

Climate change has real effects on the insurance industry says Mark Carney, Bank of England governor, in response to critics of his recent remarks on the topic. On top of the physical costs of extreme weather-related insurance losses there should be greater disclosure around the effects climate change could have on investments, he said.

Thousands of activists will take part in a series of “red line” protests at the Paris climate summit, reports the Guardian, symbolising key issues for the talks. Campaigners are promising non-violent direct action “on a scale Europe has not seen before”, it says. In another Guardian article, 10 green leaders explain how “ordinary people” can make a difference.

Politico has a primer on the EU’s energy union, launched seven months ago and still under development. The ambitious framework covers energy trading across borders, energy efficiency, decarbonisation, research and energy security, it explains. Carbon Brief introduced the energy unionand its underlying politics in February.

This month’s Canadian election is a “welcome opportunity” to change the government’s “controversial approach” to science, says James L Turk in a Science editorial. The government has been undermining and muzzling science for 9 years, he says, and this damage needs to be reversed. Pre-election polls suggest the result is too close to call, says CBC.

An “eagerly awaited” government review of business energy efficiency policies offers the chance to “do something transformative”, says a comment for Business Green. Improvements in the sector have stagnated, it argues, in part because of a complex policy landscape. New policies should include annual reporting, corporate reporting and potentially incentives, it says.

The Economist looks at India’s development and what it means for the climate. India is on the way to becoming the biggest contributor to emissions increases, it says, but green growth is also possible. A range of policy improvements could help India avoid the pattern of “grow first, clean up later”, the Economist concludes. The Conversation also looks at India’s choices. Climate Home covers a new IEA report, which finds coal use in Southeast Asia could triple.

It is not always appreciated that the choice of baseline period can affect conclusions about how well models simulate past climate and what the magnitude of future changes could be, a new study says. In the article, the researchers discuss some of the key issues that arise when using anomalies relative to a baseline period to generate climate projections. A long baseline is generally preferable, the researchers say, and studies should examine how alternative baseline choices affect their conclusions.

A new study reviews recent progress in reducing the common issue of climate models creating a double Inter-tropical Convergence Zone (ITCZ). The ITCZ is a huge single band of low pressure that is the main source of rain for tropical Africa. Climate models often produce a double band over parts of the tropics, simulating too much rainfall in some areas and not enough elsewhere. The study finds “virtually no improvement” in many of the aspects of double ITCZs between the third and fifth iteration of the collection of global climate models used by scientists around the world.
