Many model pathways designed to meet the climate goals of the Paris Agreement rely heavily on large-scale carbon dioxide removal (CDR), also known as “negative emissions”. This has prompted concerns that the promise of being able to use CDR in the future might dilute incentives to cut fossil fuel use today, a phenomenon known as “mitigation deterrence”. Heavy reliance on negative emissions is problematic because the feasibility of large-scale CDR is highly uncertain. The promise of carbon removal could be used to delay or deter action in the present, but it could then fail to show up at scale when needed. In new research published in Environmental Research Letters, we explore the implications of uncertainty over whether CDR will become available as expected. Our analysis finds emissions should be cut twice as fast during the 2020s to keep warming “well-below” 2C while insuring against CDR failure, even if the chances of non-delivery are small.

There’s likely to be a significant increase in the number of lawsuits brought against fossil fuel companies in the coming years, say researchers. Their new study finds that to date, lawyers have failed to use the most up-to-date scientific evidence on the cause of rising temperatures. As a result, there have been few successful claims for compensation. That could change, say the authors, as evidence linking specific weather events to carbon emissions increases.

Canada has recorded its highest temperatures on record as the country’s west, along with the US Pacific north-west, suffer an unprecedented heatwave. The village of Lytton, in the interior of southern British Columbia, saw the mercury hit 46.6C on Sunday – an all-time high in the country’s 84-year-old record, officials said. The previous national record was 45C, which was set in Yellow Grass and Midale in Saskatchewan in July 1937.

When the full midsummer heat hits Jacobabad, the city retreats inside as if sheltering from attack. The streets are deserted and residents hunker down as best they can to weather temperatures that can top 52C (126F). Few have any air conditioning, and blackouts mean often there is no mains electricity. The hospital fills with heatstroke cases from those whose livelihoods mean they must venture out.

Experts have warned that climate crisis and land-use changes could be creating a conducive environment for flesh-eating leishmania parasites to infect more people in the US. Numerous studies by climate researchers across the world have already highlighted the increasing risk of insect and pest-borne tropical diseases spreading to temperate and colder parts of the world like Europe and parts of the US with rising global temperatures.
