London (CNN)UK summer temperatures are set to hit new highs and deadly heat waves are projected to become a bigger problem because of climate change, according to a report from an official government adviser on Thursday.
Killer heat waves will become more common in UK, lawmakers warn
The country is currently in the midst of one of the hottest summers on record, according to the Met Office. A "level three heat-health watch" has been issued for much of southern and eastern England with temperatures predicted to rise to 35 degrees Celsius (95 Fahrenheit).
The Environmental Audit Committee -- a cross-party panel of UK lawmakers -- found that Britain is unprepared for increasingly common periods of extreme heat.
It warned that the number of heat-related fatalities in the UK will triple to 7,000 a year by the 2050s, especially among older people who are "vulnerable and suffer increased fatalities from cardiac and respiratory disease during heatwaves."
Homes and buildings, including hospitals and care homes, built to keep the heat in, are at risk of overheating, the committee found.
