Adapting to hotter temperatures is sensible – but ignoring their causes is dangerous

Weather systems are highly complex and scientists are cautious about assigning specific causes to one-off events. But experts are already pointing to global warming as a driver for the current heatwave, with a study based on computer models and temperature data due to be published by scientists at Oxford University on Friday. Meanwhile, a new report from the environmental audit committee points to the likelihood of more frequent heatwaves in future, and the UK government’s failure to prepare adequately for them.
There’s nothing wrong with enjoying the heatwave, as many people are. Such a long spell of warm weather is extraordinary and, for sun lovers, a treat. No doubt many are hoping it doesn’t break before they take their holidays. But whether or not any more records are broken, or wildfires ignited in the coming weeks, the claim that rising temperatures have nothing to do with the global state of extreme weather must not go unchallenged.
When the former US environment secretary Scott Pruitt was asked about climate change following Hurricane Harvey last year, he said that it was not the right time to talk about it. The opposite case is that the aftermath of an extreme event, when the atmospheric conditions have become the news, rather than the backdrop to the news, can be a “teachable moment”, when different kinds of conversations become possible.
One of those conversations is the one about adaptation. Since some effects of climate change are now inevitable, we must deal with them. As this week’s committee report says, building regulations must be altered to ensure heat resilience, and new measures must be brought in to improve drainage and water efficiency.
Treating the symptoms of climate change makes no sense if the causes are not tackled at the same time. British laws – as well as the Paris agreement – commit the UK government to doing this, meaning decarbonisation of the electricity supply, heating and transport. These measures have cross-party support, but commitment by politicians is inconsistent. Just a few weeks ago, parliament approved a new runway at Heathrow, a decision that now faces a legal challenge. This week, the government gave approval for fracking in Lancashire, enraging all those who fear that this is proof – combined with slashed solar subsidies, the de facto ban on new onshore wind farms, and the rejection of the Swansea bay tidal scheme – that the government is unenthusiastic about renewables.
Enjoy the sun if you can. We only live once and in countries with temperate climates such as the UK not all of the effects of climate change are necessarily harmful. Domestic tourism could even benefit. But don’t lose sight of the suffering caused by higher temperatures. In all our hands rests the future of life on earth.
