Later this year the UK will host a huge meeting called COP26, where leaders from all over the world will come together to discuss climate change, the effect it is having, and make commitments on how to reduce them.

Extreme weather and its effect on countries around the world will be a talking point at this year’s event.

So how do extreme weather events tell us more about how our climate is changing? And what can be done about it? To find out more visit the Newsround website: https://www.bbc.co.uk/newsround/57912333

Attribution studies is the name that weather experts give to the process of linking weather events to human-influenced climate change.

So far scientists have published more than 150 attribution studies looking at weather events around the world.

Here are some of the things the Met Office says it has discovered:

Heatwaves – Almost all studies on extreme heat events found that they are becoming more likely and more extreme because of climate change influenced by human actions. The Earth has warmed by about 1.2C already since pre-industrial levels – so that extra heat is added to every naturally-occurring heatwave.
Drought – About half of the studies on drought showed significant human influence.
Extreme rainfall (which can cause flooding) – Many factors contribute to flooding, but an increasing number of studies on extreme rainfall have found that a warming atmosphere caused by climate change makes extreme rainfall more likely.
Tropical storms and hurricanes – This one is complicated, according to the Met Office. There is strong evidence that warming sea temperatures increase the intensity of tropical storms. As well as this, rising sea levels also increase the risk of coastal flooding. However, there may be an overall decrease in the total number of global tropical cyclones.

This video was recorded on April 16th, 2021, and was first published on this channel on July 14th, 2021.

Items discussed include the following:
– Given the land and oceans continue to warm, EWEs will increase in frequency, severity, and duration.
– The toll EWEs are placing on our infrastructure and food supply.
– Both Hurricane Harvey and Katrina are discussed.
– The inevitable need for people to migrate inland from coastal cities as a result of Sea Level Rise (SLR) and EWEs.
– The reasons for the increase in EWEs is discussed.
– The EWEs we are seeing today can no longer be considered ‘natural.’
– The fact that according to the UN, EWEs have doubled in frequency over the last 20 years
– The fact that we can no longer count on the relatively stable climate of greater than 50 years ago, ‘The Holocene’, and that we have moved to a new age, ‘The Anthropocene’, where the climate will be much less stable
– The need for more aggressive activist movements to spur government action such as Extinction Rebellion.
– The impact of EWEs on crop yields
