The searing heat that scorched western Canada and the US at the end of June was “virtually impossible” without climate change, say scientists. In their study, the team of researchers says that the deadly heatwave was a one-in-a-1,000-year event. But we can expect extreme events such as this to become more common as the world heats up due to climate change.

The deadly heatwave that hit north-western US and Canada in late June would have been “virtually impossible” without human-caused global warming, a new “rapid-attribution” study finds. The event, which saw temperature records shattered by as much as 5C, has been linked to hundreds of deaths in the Pacific north-west region. The heatwave was “so extreme” that the observed temperatures “lie far outside the range” of historical observations, the researchers say. Their assessment suggests that the heatwave was around a one-in-1,000-year event in today’s climate – and was made 150-times more likely because of climate change. The analysis also finds that, if global warming were to hit 2C, a heatwave as extreme as seen last month would “occur roughly every five to 10 years” in the region.

More than 8 billion people could be at risk of malaria and dengue fever by 2080 if greenhouse gas emissions continue to rise unabated, a new study says. Malaria and dengue fever will spread to reach billions of people, according to new projections. Researchers predict that up to 4.7 billion more people could be threatened by the world’s two most prominent mosquito-borne diseases, compared with 1970-99 figures. The figures are based on projections of a population growth of about 4.5 billion over the same period, and a temperature rise of about 3.7C by 2100.

George Monbiot: How the BBC let climate deniers walk all over it. The fossil-fuel multinationals fund ‘thinktanks’ and ‘research institutes’. But it’s gullible public service broadcasters that give them credibility.

Thirty years ago the explorer Robert Swan walked 700 kilometres (435 miles) across Arctic sea ice in a 56 day springtime trek to the North Pole. Today, that ice is mostly water, according to Mr Swan, the first person to walk to both the North and South Poles and perhaps the world’s greatest “climate witness”.

Record-breaking heatwaves have dominated the news recently, affecting large parts of North America, Eastern Europe and even the Arctic, and bringing with them headlines of infrastructure collapse, suffering and death more commonly associated with major natural disasters such as floods or wildfires. In Portland, America, where residents used to a more temperate climate do not have air conditioning in their homes as standard, cooling centres were opened to provide brief respite. And in Islamabad, Pakistan, 20 children in one class fell unconscious – with some suffering nose bleeds – amid sweltering 40C heat, according to local reports. On Wednesday the EU’s Earth observation programme confirmed that June was the hottest on record for North America, and the second hottest for Europe.
