| An amber warning means the whole health service is likely to be affected by the hot weather. | |
| Among examples given by UKHSA are difficulties managing medicines, the ability of the workforce to deliver services and internal temperatures in care settings exceeding the recommended thresholds. | Among examples given by UKHSA are difficulties managing medicines, the ability of the workforce to deliver services and internal temperatures in care settings exceeding the recommended thresholds. |

| Some locations in Lincolnshire and Suffolk have already had two consecutive days where the temperature has exceeded the heatwave threshold of 27C. Thursday would make it a third day which would therefore place these parts in an official heatwave. | Some locations in Lincolnshire and Suffolk have already had two consecutive days where the temperature has exceeded the heatwave threshold of 27C.

| Climate change is continuing to drive global temperatures upwards and make extreme weather events more likely. | |
| Leading scientists on Thursday warned that there were as little as three years left to limit global warming to 1.5C - the target that had been set by the Paris agreement in 2015. | |
| Nearly 200 countries agreed to try to limit global temperature rises to 1.5C above levels of the late 1800s, with the aim of avoiding some of the worst impacts of climate change. | |
| Last year was the hottest year on record and the first above the threshold - though a single year does not constitute a breach of the agreement. | |
| The Met Office said heatwaves were 30 times more likely to occur than before the industrial revolution - and were projected to become even more common, potentially occurring every other year by the 2050s as greenhouse gas concentrations continue to rise. |
