because of emissions produced by burning fossil fuels like oil, gas and coal. yet global temperatures oil, gas and coal. yet global temperatures are oil, gas and coal. yet global temperatures are heading . temperatures are heading towards 1.5 celsius above preindustrial levels, and if they go to 1.8 celsius, scientists want that half the world s population could be exposed to life threatening heat and humidity. exposed to life-threatening heat and humidity.- heat and humidity. climate scientists heat and humidity. climate scientists have heat and humidity. climate scientists have warned - heat and humidity. climatei scientists have warned that change needs to come from the top, from governments and companies. once science and innovation will play an important part.- innovation will play an important part. innovation will play an imortant art. . , important part. yeah, so this week we re important part. yeah, so this week we re going important part. yeah, so this week we re
here is a thermal imaging camera and you can see the temperature is about room temperature. but when i point this at the air that is coming out of the moss when you switch the ventilation on, look how much cooler it is. so not only does this clean the air, it cools it as well. and of course, pulling pollutants out of the atmosphere could help cool more than just your local surroundings. flair cool more than ust your local surroundings. cool more than ust your local surroundings. air pollution and climate change surroundings. air pollution and climate change are surroundings. air pollution and climate change are also - climate change are also directly related. you have pollutants in air pollution, for example black carbon, which speed up the heating of the planet. and by binding those pollutants, we also help to decelerate climate change. you will already decelerate climate change. you will already see decelerate climate change. you will already see these biofilter s in seve
kills an estimated 7 million people worldwide every year. now we are not all going to move back to nature, but what if we could bring nature into the cities? just outside berlin, this company is trying to freshen up our urban air. this is a biofilter which is sucking air in through the bottom and pumping it back out through this wall of moss. to illustrate, we have a smoke machine from the local discotheque and if ijust show you, there you go, it is straining out through the moss. and as the air comes back out through the moss is where the magic happens. moss eats pollution. it sticks to its tiny leaves, it is absorbed, digestive and then is turned into more moss. so as fans draw dirty air in, the bad stuff is left on the moss s leaves,
