Everybody speaks about flu shots – but there might be no seasonal flu this winter because of social distancing and hygienic measures against COVID-19.

Richard Betts Misunderstands Basic Science
By Paul Homewood
When in a hole, stop digging Richard!
From NTZ:
Just recently Anthony Watts posted an article on wildfires penned by Paul Homewood. Lately alarmists have been blaming the active forest fire season on global warming. They warn that warmer temperatures will lead to more wildfires.
Is it so?
First it’s important to note that warmer temperatures don’t necessarily lead to more drought and wild fires. For example in 2018 I reported here how the Sahara desert has shrunk by a whopping 700,000 sq km over the recent decades, even though this is a region with very warm temperatures.
Also we know that the earth’s surface has often been drier during cooler times.
Moreover, aspiring meteorologist Chris Martz here explains that long-term forest fires have not been getting worse in the USA, and “are nowhere near as bad as they used to be”.
U.S. wildland fire counts by year since 1926 (Figure 5a – left) and U.S. wildland fire burn acreage over that same time period (Figure 5b – right).
Climate scientist doesn’t understand why forests dry
On the WUWT article I commented at Twitter that when it comes to wildfires, temperature is not a factor behind them, to which University of Exeter, Met Office, IPCC. UK Climate Prof. commented:
Most laypersons of course believe that higher temperatures “dry out” surfaces and fuel faster, as climate expert Prof. Richard Betts obviously did. After all, we use a hair dryer to dry our hair more quickly, or throw our wet laundry in the dryer. So most people think that it’s the high temperature that is doing the drying. But that’s not quite how it works.
Astonishing misunderstanding of fundamental science
We can forgive a layperson for misunderstanding this fundamental science, but it is spectacularly astonishing that a supposedly distinguished climate professor such as Prof. Betts would misunderstand it. How on earth could someone with such a fundamental misunderstanding be expected to explain climate to us, let alone model it?
Or perhaps, in his desire to be dramatic, he got sloppy and miscommunicated it.
It’s the relative humidity, stupid!
There’s only one factor behind drying forest, grassland, ground surface: the relative humidity of the air next to the surface (difference temperature and dew point) and precipitation.
If the air has a very high relative humidity, then drying will take a long time, no matter what the temperature is. If temperature was the main factor behind drying, then places like the Amazon, Congo or Southeast Asian rainforests would have dried up and burned long ago. But they haven’t.
In fact the planet’s biggest deserts are the Arctic and Antarctic. Last I checked they are still cooler than the Amazon.
It’s not the temperature!
To help drive the point home to the MetOffice climatologist, veteran meteorologist Jörg Kachelmann at Twitter joined in, asking Prof. Betts:
Kachelmann added:
Remember, these are the scientists who provide the input into the climate models.

UGLY: ‘Climate emergency’ soon to justify ‘house arrest’
Anthony Watts / 3 hours ago September 30, 2020
‘Climate emergency’ means house arrest: COVID ‘has revealed the inner-tyrants of many politicians’
By Peter Murphy – Policy Analyst, Committee For A Constructive Tomorrow (CFACT)
“Under the pretense of a ‘climate emergency,’ politicians and bureaucrats will increasingly impose Covid-like restrictions on our jobs, transportation, food choices, housing and much else based the purported need to ‘reduce greenhouse gases.’
Not surprisingly, the once Golden State is leading the way. The Metropolitan Transportation Commission, a government agency in the San Francisco Bay area…recommends billions of dollars for job training, affordable housing, high-speed internet, adaptions for “sea-level rise” (est. cost: $19 billion), “retrofit” residential buildings ($15 billion), and “enable carbon neutrality” for all existing public and commercial buildings ($18 billion).
…
This central planning scheme also includes this doozy: “allow a variety of housing types at a range of densities” including in areas “with the region’s best schools and economic opportunities.” Translation: public housing projects are coming to suburban communities.
