“Record-shattering” extremes – which break weather records by large margins – will become more likely as a result of climate change, a new study finds. The paper, published in Nature Climate Change, finds that the northern mid-latitudes are particularly vulnerable to record-shattering heat. This is exemplified by the recent heatwave over north-western US and Canada, in which many long-standing temperature records were broken by as much as 5C.

A new study tracking the planet’s vital signs has found that many of the key indicators of the global climate crisis are getting worse and either approaching, or exceeding, key tipping points as the earth heats up. Overall, the study found some 16 out of 31 tracked planetary vital signs, including greenhouse gas concentrations, ocean heat content and ice mass, set worrying new records.

The water war of the 21st century could come in two forms. The first would be in a mismanaged or panicked response to rising seas. Around 150 million people live one metre or less above current sea levels. Many will be displaced and become climate refugees, creating huge instability. The second kind of war may be just around the corner. The Egyptian leader Abdel Fattah al-Sisi has warned Ethiopia he wouldn’t rule out using military force if the huge new “Grand Ethiopian Renaissance Dam” means Egyptians going without water further down the Nile. The ambition of the Nobel peace prize-winning Ethiopian premier, Abiy Ahmed, is to fill a reservoir to create the biggest hydroelectric plant in Africa and thus become a major energy exporter. Sisi worries that the Ethiopians are unilaterally discarding the colonial-era share-out of the Nile waters between Egypt and Sudan. He fears not only the loss of drinking water — the Egyptian population is growing at the rate of 1.5 million a year and by 2025 water supply will drop below 500 cubic metres per capita, a level that hydrologists call “absolute scarcity” — but also a loss of face. Ethiopia’s leader is staying cool. “No force can stop Ethiopia from building a dam,” Ahmed says. “If there’s a need to go to war we could get millions readied.”
