surface temperatures at the moment, somewhere between 87 and 95 degrees. so many people don't think that climate change is real.

itjust was extremely hot and everyone was starting to get worried, day by day, until it happened. temperatures will climb well into the 40s, making conditions even worse on ourfire grounds. the footage that i took of the fire was shot on the gopro that i had actually got for christmas five days before the event. it was on a very hot day to begin with, so that made the fire, i think, a lot more aggressive. in the afternoon, i got the first glimpse of the fire coming over one of the mountains in front of us.

it's so much smokier over there. it then started behind our house and i was just standing up there, thinking, "bleep, this is happening. "i need to get off the roof now and start fighting." whoa, kangaroo! ok, it's coming this way! should i get the other pump going? what? what should i do? the fire was just too intense and out of my control. dad! and if india had been in earshot at the time, i was wanting her to get into that fire shelter and just give up. n-s — we've done the best we can. oh, no! no, no, no! it did get really intense and i thought we were going to lose the house. um...but itjust calmed down for a second and the fire kept

going up the mountain. oh, yeah. it has completely and utterly changed the landscape here for the rest of my life, if not forever. as far as any of the tall trees, mostly all of them have been wiped out. we are right still in

the middle of this heatwave, so as we head into the christmas period... that is what happens when you wake at 5:30am! so there's very strong evidence — irrefutable evidence, in fact — that the climate of australia has changed, especially over the last 50 or 70 years. i specialise in heatwaves so i study how heatwaves have changed over time and what's causing those changes. i have a 2—year—old and a 4—year—old daughter. it really bothers me that the world that they're experiencing now is a lot different to my childhood. i've experienced days of 45 and 47 degrees celsius and that was appalling. it was atrocious. you couldn't do anything. the only way we could stay cool in western sydney was to have the air con

running all day, and that was a really hard thing for me to do. during my first pregnancy, it was so hot that i actually struggled to go and put the washing on the line. while i was literally about to bring this child into the world, i was thinking, what would summers be like for her in the future? it was the hottest day ever recorded in the sydney basin. incredibly, the mercury rising to almost 49 degrees. because population increase in sydney is continuing, it's spreading out west. the australian dream, where you had your half acre or acre block and your own house — this australian dream could become, basically, australia's nightmare. you need a car to actually get from your house to work, because we are also not

providing work where you live, you have to commute. also, there are no shops. people living indoors and you don't see anyone outside, i don't see any kids playing outside. they even put black roofs on top of these houses and then they build them so close together that you have no more space left to actually put trees in, which is crazy when you think of the next 20 or 30 years when we know it is getting hotter out there. in australia, we're producing our energy to a large proportion by burning fossil fuels, meaning we're producing more co2 by having all these air—conditioning units running high, flat—out. but there could be simple changes made, and these changes relate to materials. one of the projects where we are demonstrating change is the cool roads trail.

let's take the heat—stress trekkers and put them out in this cool street, and we'll collect some measurements on this stinking hot day. this yellow concrete is only at about 60 degrees, so nearly 10 degrees cooler than the asphaltjust out on the road, which is 70—72 degrees. it is quite interesting. they removed all the bitumen and you can see the different surface materials bringing in the verges, planting more trees, so i think it's a great idea. beyond 42 degrees, mortality increases substantially. this is what climate change looks like, ladies and gentlemen. in november2018, up to one—third of the entire australian spectre of flying fox population just died — in a matter of two days. in two hot afternoons. just like that. so, over the last few years, we've begun installing sprinklers in flying fox camps

in the hope that they can prevent some of the worst of the mortality. the international report has australia last when it comes to policies that protect the climate, trailing countries like russia, iran and china. if he said we were doing better than anyone else, he must have looked at the table upside down. our goal is to reach net zero emissions as soon as possible, and preferably by 2050.

we're not going to reduce our emissions to 2 degrees warming by the end of this century. i know that we're probably going to reach 3 or 4 degrees, and i know what that means for how many more heatwaves we're going to see and how much hotter those heatwaves will be. sweetheart, you're meant to be unpacking, not packing! as a scientist, i know how bad the future looks. i understand that, i comprehend all that, that's what i do for a living. but as a mum, as a person, i guess, as a human being, i really struggle with just how bad those impacts will be. i'm worried for my future. i'm worried that this house won't be here in another five years, and i'm worried that no—one really cares enough to do anything.

so, what plants do you think we should plant in our backyard in our new house? strawberries. - you want strawberries? the brand—new house is going to be awesome. we're going to make it energy efficient and we're going to have lots of solar panels and a white roof and lots of insulation and it's going to be oriented the right way and we will have an electric car, when we can buy it. i know we've caused some problems, and i know we also hold the key to the solutions. what else do you like to eat that you think we can grow in our yard? how about some apples? ooh, mummy likes apples!

hello. from friday a little bit cooler. this is the pattern across the north atlantic and cream and coping around and then we are right underneath then we are right underneath the jet stream. it means that the jet stream. it means that the to the south of us and actually quite extreme heat. a

carving of a much of europe at the moment. you'll be seen to be on the edge of those high temperatures and, in fact, in parts of spain and into northern italy, those values could hit extreme figures around the mid 40s, is quite possible. at any point during the summer, would be on the anyway, back to our neck of the woods. here is thatjet stream at 30,000 feet and you can see it really is right over us. this is where the more temperate weather is. wednesday's early forecast, then, she has plenty of clear weather or mostly clear across much of the country. a little bit of rain getting into parts of wales in the morning so perhaps thicker cloud and some dampness for swansea and for cardiff but, generally speaking, it is advised out. that should away as well and then, part mesh few showers around the western isles it is going to be a bright day if not a sunny day and the best of the

sunshine will be a little bit further towards the east and south. look at these temperatures. high teens for loath into scotland and across northern ireland. let's have a look on thursday. and here we have the pressure is over us and that means thicker cloud and that means thicker cloud and with weak weather fronts crossing the country i think a greater chance of catching a shower across the south of the country but you can see, certainly, water. plenty of big gaps between the showers. on thursday, a generally dry day. 19 in belfast, not bad at all. still holding on to the warmth in the south and the south—east at around 25. on friday, this area of low pressure would get the drift towards the east and, following the size of boris, the wind will start to start to come in from the north so that means that temperatures will ease. they will probably use more in the south and in the north. in the north were still talking the high teens for

belfast made by newcastle but in the south, about 21 or 22. and again, fairamount in the south, about 21 or 22. and again, fair amount of dry and bright weather with just there and on saturday it is such a sluggishly slow area of low pressure moving towards the east. high pressure is, in fact, building and in the wake of this low. out in the west. the winds northerly. the temperatures are not going to be particularly high but it is a pretty decent today. this is the forecast for friday, then, for the end of the week ended the weekend. we are expecting temperatures in the low 20s. how about the outlook for the west of the weekend? and into next week, temperature stabilising in the high teens across the north of the country. will stay about 20 in the south end, i think, bright spells but occasional showers. no real need changes expected to our weather, at least not for now.

live from washington. this is bbc news. wildfires kill at least 18 people in greece. officials say they're likely migrants crossing from turkey. a legal shadow hangs over a political showdown. donald trump, the republican presidential debate , and the elephant not in the room. and, building a case for the brics alliance. leaders of brazil, russia, india, china and south africa try to present a united front injohannesburg. we begin in greece where 18 bodies have been found in a national forest where wildfires have been raging for days.
