The Japanese conglomerate Toshiba has forecast a loss of £7bn, the Guardian and others report, putting its future in doubt. The firm has finally released twice-delayed third quarter results, without the approval of auditor PricewaterhouseCoopers Aarata, the paper adds. Toshiba’s filing says there is “substantial doubt about the company’s ability to continue as a going concern”, says the Times. Toshiba could be delisted from the Tokyo stock exchange over PWC’s refusal to approve the accounts, the Financial Times notes, because this raises “new questions” about internal controls found inadequate in a 2015 accounting scandal. The firm is considering selling a stake in its planned Moorside new nuclear project in Cumbria, reports the Telegraph. The troubles at Toshiba mean UK nuclear plans are “in meltdown”, says the Daily Mail. The Press Association and the Independent also have the story. Earlier this year, Carbon Brief looked at how important the Moorside project was to UK climate plans.

The government should explain its failure to publish the long-delayed emissions reduction plan within 21 days, says environmental law NGO ClientEarth, according to a report in the Independent. In a letter to climate minister Nick Hurd, ClientEarth does not threaten legal action, the paper notes, but it does say it would “appreciate a response within 21 days”. The NGO told the Independent it might take the government to court if it does not receive a response to its letter, though it would prefer not to. The Press Association also covers the story.

The BASIC group of China, India, Brazil and South Africa have called on rich nations to honour financial commitments on helping developing countries fight climate change, reports Reuters. Following a BASIC meeting in Beijing, China led calls on the the US to stick with the Paris climate accord, reports Bloomberg. The BASIC group says there is a gap of at least $40bn between existing financing commitments and a pledge to reach $100bn annual contributions by 2020, reports the Financial Times, with India expressing scepticism over estimates of current flows. A meeting two weeks ago between the EU and China involved “‘uncharted waters’ regarding ‘differences in approaches to climate financing'”, according to EU climate commissioner Miguel Arias Cañete, in comments to the FT.

The first quarter of the 2017 saw a 17% fall in clean energy investment, according to Bloomberg New Energy Finance figures reported by Bloomberg. Falling support for renewables in China and the US explains the reduction to $54bn, from $65bn in the same period last year, Bloomberg says, adding that analysts believe it is too early to say whether 2017 as a whole will see lower investment than 2016.

The so-called little ice age, when the Thames regularly froze over, had scorching summers as well as very cold winters, according to new research by the Royal Astronomical Society covered by the Guardian’s Weatherwatch column. The findings suggest it was not an ice age at all, the column notes, with average temperatures during the period at most half a degree lower across the northern hemisphere.

Statements about climate science from president Trump, US Environmental Protection Agency administrator Scott Pruitt and US House Committee on Science, Space and Technology chair Lamar Smith are “misguided”, say climate scientists Kevin Trenberth and Reto Knutti, in an article republished by DeSmog Blog. “They show a woeful ignorance about science and how it works, and in particular about climate science,” they write, before going on to explain how scientists use models to make projections and how their work is both “transparent and reproducible”.

The main sources of uncertainty in measures of global temperature are not those that have been subject to the most scrutiny, says McGill University’s Shaun Lovejoy, in a guest article for RealClimate. Rather than urban heat island effects, it is missing data and time scales that are the largest source of uncertainty, Lovejoy says, explaining his recently published research.

The heads of Shell Canada, Canada’s largest oil company Suncor, Shell, BP and ExxonMobil have all expressed recent support for a carbon tax, writes Tina Rosenberg in a comment for the New York Times. Nearly half of Trump voters support a carbon tax, she adds, noting a recent proposal put forward by prominent Republicans “has at least started a debate”. Rosenberg goes on to give examples of effective carbon taxes, citing Carbon Brief analysis showing the UK’s carbon price floor has helped cut emissions to levels last seen in 1894.

Rice yields in Mainland Southeast Asia could decline by more than 10% per degree of temperature rise, a new study suggests. Using a regional rice model and projections for future climate, the researchers find that positive effect of CO2 fertilisation only partially offsets the negative impacts of climate change on rice. The use of heat tolerant rice varieties and shifting planting dates are adaptation options that may help limit a fall in yields, the study says.

A new study compares public perception in Germany of three options for geoengineering: solar radiation management (SRM), large-scale afforestation, and carbon capture and storage under the seabed (CCS). Surveys indicate that afforestation is most readily accepted as a measure for addressing climate change, followed by CCS and lastly SRM, which is widely rejected. The acceptance of all three options is influenced by perceived seriousness of climate change, the researchers say, while respondents dislike the measures more if they perceive them as a way of shirking responsibility for emissions or as a manipulation of nature.

The has been a significant reduction in CO2 emissions intensity of new cars since 2007 across most EU member states, new research finds. This is likely a result of EU-wide policies – such as the CO2 vehicles regulation – along with the economic recession, the researchers say. Generally, countries with CO2-specific vehicle taxes are more likely to have achieved greater reductions in CO2 emissions, the study finds.
