The Vietnamese Bach Ma Mountain Peak station recorded one-day rainfall of 1,739 mm - close to the global one-day record and perhaps a new record for the northern hemisphere. It is part of a deluge Viet Nam has seen in October, shattering 35 precip records. e.vnexpress.net/news/news/en...
Vietnam sees 35 rainfall records broken in October - VnExpress International

Rain in the Sahara? Researchers predict a wetter future for the desert
The Sahara Desert is one of the driest areas in the world. It gets just 3 inches of precipitation per year—one-tenth of the amount of Chicago's rain, sleet and snow.

Specifically, in our paper we argue that RCP4.5 or RCP6.0 are more realistic representations of 2100 warming under current policy than the increasingly implausible RCP8.5 scenario. But the lower of those two – RCP4.5 – gives a 2100 warming range of around 1.8C to 4C!

A glacier partially collapsed in Switzerland, burying the village of Blatten in a huge landslide of ice, rock, and mud after residents had been evacuated.
Scientists called the collapse of the glacier “unprecedented” in the Swiss Alps.

Trump administration cuts to NSF will result in more than 200,000 FEWER people per year involved in basic science, training, and education - what should have been the next generation of US scientists. This isn't even eating your seed corn, it is setting your seed corn on fire and salting the earth.

The mountains feeding the Colorado River have less than 50% of the average snowpack for this time of year. This means that the Colorado River could see low water volume, putting the millions of Americans who rely on it for drinking water, agriculture, and hydropower at risk.

Scientists have been publishing climate models since ~1970.
A good way to evaluate their skill is to compare what they expected to happen in the years after the model was published to observed climate changes.
It turns out most models were pretty spot-on:
