The Biden Effect

Memorial Day weekend will be the coldest on record by a wide margin in Washington DC. The average maximum temperature at Laurel, MD (just north of DC) is forecast this weekend to be 53F. The average May 29-30 temperature at Laurel is 78F and the previous coldest was 63F in 1996. The hottest years were 1969 and 1991 at 97F.

Across the US, May afternoon temperatures peaked in 1934 and have been declining since ever since.

The first warm day is coming later.

The frequency and extent of hot weather during May has been declining.

May 1911 brought 104 degree temperatures to New England.

May 1934 was the hottest May of the past century, but the following May was the coldest.

Besides being cold, this weekend in 1935 brought world record rainfall to Colorado and Texas. On May 31, 1935 Woodward Ranch, Texas set the world record with 22 inches of rain in less than three hours.

Colorado got nearly that much rain a few hours earlier.

This came a few weeks after record dust storms and a few weeks before the most intense hurricane in US history.

But never mind history, science, reality or veracity – The National Post says heat from climate change is driving people to suicide.

Prior to air conditioning, many people did commit suicide from the heat – like during the record heatwave of 1911.

The National Post article has nothing to do with reality. Heatwaves in Toronto are no worse than 80 years ago.

Heatwaves in the US have plummeted as CO2 has increased.

Nothing that Biden is doing will have any impact on the growth of CO2

Fossil fuels make air conditioning and central heating possible, which make all kinds of unlivable climates livable. And Joe Biden wants to take them away. On Memorial Day weekend 49 years ago I travelled to Kanab, Utah in very hot weather and testified at a Congressional hearing in support of a wilderness area. The venue was sweltering. This year I have the heat turned on.
