The latest fake news from the BBC: Dry heat to torrential rain – enter the age of ‘weather whiplash’
After weeks of dry, sunny conditions in Scotland, torrential downpours over the bank holiday weekend marked a sudden change in weather.
Barely a drop of rain was recorded over almost the entire month.
March and April were far drier than normal, with May seeing only 4% of the normal rainfall by the middle of the month.
This flip between extremes has introduced a new phrase to our forecasting vocabulary – weather whiplash.
Some scientists believe we will have to get used to the idea that our weather will see wild swings from one extreme to another over short periods of time because of climate change….
Before the weather turned last weekend, Scotland had only recorded 41% of its usual spring rainfall, with just seven days left of the season.
This switch is driven by a warming world speeding up the water cycle and allowing the atmosphere to hold more water. So when it does rain, the rain is heavier, which in turn can lead to flooding.
We know that our weather will continue to become more extreme, because global temperatures are rising due to human-induced climate change.

Obviously the weather has never swung from one extreme to another!
And true to form, the BBC, or their so-called scientists, offer no data at all to back up their assertion.
Indeed, no such evidence exists; on the contrary the data shows nothing has changed over the years.
Here’s some of the evidence:
Although April was drier than average, it was not unusually so, nor is there any trends either way.
Secondly, we can look at the month to month changes during spring.
UK rainfall is inherently variable, sometimes extremely so. For instance, rainfall in May is often considerably greater, and equally often lower. But there is no evidence whatsoever the swings have been widening over time.
Exactly the same can be said for changes from May to June.

The BBC repeat the same old lie that rainfall is heavier because of a warmer atmosphere.
The actual daily data for Scotland quite clearly shows this claim to be baseless.
The most dishonest part of the BBC report is this graph, which claims that “when it rains, it now rains more”
But Ed Hawkins’ graph does not show daily rainfall, but seasonal average rainfall.
Taking spring as an example, although the average has increased since the 19thC, that does not mean individual springs are getting wetter. What has changed is that unusually dry springs are now less common.
