00:57So all the weather extremes that we're seeing are currently occurring in a warmer atmosphere

01:26and also with warmer oceans and in an atmosphere that can actually carry more moisture.

01:32So all these actually contribute to the fact that heat waves as we've experienced them in the past

01:38become more intense and obviously also more frequent. Heavy rainfall events can also be more

01:44intense because the atmosphere can carry more moisture and interestingly the same effects the

01:49fact that the atmosphere can carry more moisture also implies that it can actually extract more

01:54moisture from the vegetation and from the surface and therefore also may make droughts more intense.

02:52I don't know.

03:22So

03:52So wildfire is a complex type of event, so there are many factors playing in, that's

04:20the management of the forest, that's where we build our homes, how much they are affected.

04:25But climate change can also play a role into all of this, and that's particularly that wildfire,

04:34that means very warm temperatures and very dry atmosphere becomes more frequent.

04:42And the reason is really typically the atmosphere that warms could actually take up more water,

04:48which also makes it, as a colleague of mine recently called it, thirstier, so it means

04:52that it can actually extract more moisture from the vegetation, from the surface, and

04:57that just means that this vegetation becomes easier to ignite, easier to burn, and that

05:05basically makes it easier for wildfires to spread.

06:05So climate change really changes the odds, the probability of these events to occur.

06:33So while we know that heatwaves and droughts and heavy rainfall have happened in the past

06:38for hundreds of years, today they come more frequent.

06:43That's really to do with the warming climate, the warming atmosphere that just intensifies.

06:48It's only one factor in the whole discussion of weather and climate extreme, but it can make

06:54the events more frequent.

06:56I think we've been observing a clear intensification or a clear increase in the number of heatwaves

07:04over Europe.

07:05We've seen more frequent heavy precipitation events, and in some regions we've already witnessed

07:12more dry locations of the land surfaces.

07:16So what used to be a very rare event has become much more frequent.

07:21For instance, heatwaves as they occurred only once in 50 years, they have become five to ten times

07:29more frequent.

07:31And this trend will continue as the climate continues to warm.

07:38And the weather can be quite intense.

07:39You'll see.

07:40You know what?

07:45I'll try to do the events.

07:47I'll do it all for a long time.

07:50I'll try to get to the weather and wind.

07:52I'll try to get to the weather, I'll try to get to the weather.

07:57I'll try to get to the weather, for an ocean, for a long time.
