Definitely read 'Treasure islands' by Shaxson, - although there is nothing you wouldn't have guessed.

Yes. A straightforward, truth-telling book and a worthy addition to your 'unputdownable' list.

Significant flooding in Lancashire, 70 persons and 20 horses rescued.

The rainfall is said to be "unprecedented" this might be journalistic exaggeration, or might be actually true.

The flooding might be unprecedented but maybe it is setting a new precedent under our new climate changed situation.

Once-in-a-1,000 years flood hits Maryland town twice in two years

These once-in-a-1,000 years events are happening at an ever increasing intensity, aren't they?

Thanks for this which I have finally got around to reading. Yes about what I guessed and worse, offshore is groaning under with the precious weight of total arseholes intent on making bad situations worse for all and sundry.

We get what we vote for.

And in Japan the floods said to be "unprecedented" with more heavy rain forecast.

Update to add, over 100 lives now said to be lost, and many more missing.
Widely reported as being the worst ever flooding.

And in France, about 1,500 people have had to be rescued from flooding at a camp site.
One person is missing and feared to have been swept away by the flood, inside a caravan.

Monsoon flooding in India is a regular event, but some reports state that this year it is worse then usual.
Numerous lives have been lost and much property destroyed already, with significant heavy rain expected.

I wonder if a heavy monsoon season extends to higher snowfall in the Himalayas helping to balance out the recent losses to their glaciers?

Been a while since I looked at this but I think there's a relationship the other way around. When there is low winter snow cover it melts sooner in the spring, the landmass warms earlier and hotter, driving a stronger monsoon. (Remember the monsoon is driven by the differential rates of ocean and land warming). I'm not aware of a link the other way around.

I read somewhere that a more humid global atmosphere, due to global warming, actually causes global snowfall rates to rise due to that greater humidity.

Generally higher temperatures will indeed increase evaporation, and that which evaporates must come down again as snow OR rain.
Higher temperatures would however increase the chance of rain and reduce the chance of snow.
In the coldest parts of the planet the water will still fall as snow.
In the warmest parts of the planet, it has always fallen as rain in any case.

In many places of intermediate climate, the proportion of snow has decreased and will continue to reduce, whilst more rain falls.
This can have disastrous consequences.

Many large human settlements are very dependant on winter snowfall on nearby mountains.
During the Summer, the snow pack on the mountains gradually melts and results in a somewhat steady flow in the rivers upon which the settlements rely.
A warming climate results in more rain and less or no snow. The rain results in downstream floods since it promptly runs down the mountain.
The absence of snow to gradually melt during the summer results in lower river flows or even complete drying, and results in drought.
