00:00The main reason we've got really high temperatures across southern Europe at the moment is due to
00:22something called a heat dome and that's where we've got an area of high pressure that's got
00:26blocked and with high pressure the air is descending and when air is descending it means that we're not
00:32going to see any clouds forming we're not going to see any unsettled weather but we are tending to
00:36see the air getting trapped and when the air is sinking it warms there's something called adiabatic
00:41warming as well and we end up with a situation where day on day if the high pressure gets stuck
00:45where it is which is what's happening we get homegrown heating adding to that so we've already
00:50got high temperatures because of the time of year but the longer the high pressure stays in place the
00:54temperatures keep rising day by day because the heat dome is almost acting like the lid in a pot and
00:58it's trapping that hot air underneath it we've seen extremely high temperatures and very dry conditions
01:03too across spain portugal france and also parts of hungary have also had extremely high temperatures
01:08and drought conditions as well so it's not just affecting one area it's quite a wide area of europe
01:13struggling with these very high temperatures at the moment which according to climate central if you
01:18take a look at the previous temperatures over like decades we can see that these temperatures are
01:25three to five times more likely than they would have been without the impact of human induced climate
01:30change so we're seeing these higher temperatures as a direct consequence of climate change unfortunately
01:36it does seem quite likely that we will be seeing more of this in the future we've had quite a few studies
01:41out earlier in the year so for example we're in the uk we're now um 50 50 chance we'll see another 40
01:48degree day within the next 12 years we're going to be seeing more days above 40 degrees certainly more
01:54days above even 34 or 35 degrees and across europe of course the temperatures are even higher and it is
02:00more likely to see more days like that but when it comes to the reality if we're talking about 40 degrees
02:05in in terms of a shade or an air temperature if you're in direct sunlight if you're on the underground
02:11if you're in a house it's not well designed then those temperatures are so much higher and that's
02:17why you know obviously such high temperatures have a really bad impact on people because we can't cool
02:21down well at night and even if the thermometer's not that high it can be so much hotter especially
02:27if the humidity is an issue as well so i think it's also worth bearing in mind that the numbers we talk
02:31about aren't the be-all and end-all it's how it feels to people that really has an impact on our health
