It's less clear cut than the main argument, I'll give you that.There's always been severe weather fluctuations, I just had a look at weather records for the UK and it's pretty much a mixed bag in terms of dates.
You'll probably find throughout the world there is nothing to suggest now is any worse than any particular time in history.
From met office:
- Extreme heat: Almost all studies on extreme heat events indicate human influence.
- Drought: About half the studies on drought show significant human influence.
- Extreme rainfall: A smaller but increasing number of studies on extreme rainfall detect a human signal.
- Tropical storms and hurricanes: The picture here is complex. There is strong evidence that increasing sea temperatures increase the intensity of tropical storms. Rising sea levels also increase the risk of coastal flooding. However, there may be an overall decrease in the global total number of tropical cyclones.
