In an unprecedented step, more than 11,000 scientists from 153 nations have united to warn the world that, without deep and lasting change, the climate emergency promises humankind unavoidable “untold suffering”. And as if to underline that message, a US research group has predicted that – on the basis of experiments so far – global heating could reduce rice yields by 40% by the end of the century, and at the same time intensify levels of arsenic in the cereal that provides the staple food for almost half the planet. And in the same few days a second US group has forecast that changes to the world’s vegetation in an atmosphere increasingly rich in carbon dioxide could mean that – even though rainfall might increase – there could be less fresh water on tap for many of the peoples of Europe, Asia and North America. Warnings of climate hazard that could threaten political stability and precipitate mass starvation are not new: individuals, research groups, academies and intergovernmental agencies have been making the same point, and with increasing urgency, for more than two decades.

Sobering report from Institution of Mechanical Engineers warns governments and businesses are ill-prepared for sea level rises expected this century. Governments around the world must urgently prepare for at least one metre of sea level rise before the end of the century, with creeping tides expected to have drastic impacts on coastal communities and infrastructure, the UK’s leading engineering professional body has warned.

A vast area of Australia’s east coast – including Sydney – is bracing itself for one of the nation’s worst ever bushfire threats. More than 50 blazes are burning across the state of New South Wales (NSW) ahead of predicted “catastrophic” conditions later on Tuesday. Authorities warn that fires will spread quickly to endanger lives amid hot temperatures and strong winds.

Australia is enduring a bushfire crisis that has left three people dead, razed more than 150 homes, and prompted warnings of “catastrophic” danger. Bushfires are a regular feature in the Australian calendar, but the blazes in New South Wales and Queensland have not previously occurred on such a scale and so early in the fire season, officials say. This has led many Australians to ask how closely the fires can be linked to climate change. The science around climate change is complex – it’s not the cause of bushfires but scientists have long warned that a hotter, drier climate would contribute to Australia’s fires becoming more frequent and more intense. But the nation’s political leaders are facing a backlash for batting away questions on the subject.

The biggest and most damaging hurricanes are now three times more frequent than they were 100 years ago, say researchers. Using a new method of calculating the destruction, the scientists say the increase in frequency is “unequivocal”. Previous attempts to isolate the impact of climate change on hurricanes have often came up with conflicting results. But the new study says the increase in damage caused by these big cyclones is linked by global warming.

Richard Dixon: Climate change can cause deaths as a result of wildfires and droughts but also through the release of viruses and bacteria held in the ice. And if we carry on increasing carbon dioxide into the atmosphere, it could even affect our intelligence, writes Dr Richard Dixon. There are many ways in which climate change affects the health of people and nature. One of the most unexpected is the small but real danger of diseases from the past arriving in the present as ice and permafrost melts.
