2020 & 2021 were/are Lockdown Years.But if you look at the Mauna Loa data, there is nothing to suggest that 2020 or 2021 (so far) were in any way different from any other year in terms of temperature and CO2 concentration. Which casts a shadow of doubt on the importance of the anthropogenic contribution to either.
Most of Us sat Indoors.
Lot of pattern changes in the ambience of the environment, Right?
Perhaps Our drastic change in actions might somehow explain the " Weird " Climate.

But does the Water have to be Heated?Dishwasher tablets and solutions are designed to work at higher temperatures and deliver a higher pH than handwashing detergents. Their ability to scour and saponify grease is greater than you can achieve with a simple surfactant, and is positively harmful to bare hands.

Interesting how the simplest of everyday observations has drawn a complete blank from all the resident geniuses, but everyone has an opinion on dark matter, the evolution of consciousness, and the quantisation of time!
And just for the record, I don't know either.

Islam is very focused on communal operation, ie Afghanistan new beard and Burka trend for everyone and the importance placed on community. Judaism seems far more individual based, personal achievement.All religions attempt to control people's dress and behavior. They are despicable because these controls are based on an imaginary authority, not common sense or common benefit.

And you have swallowed the propaganda.The Road Haulage Association has always been pro-EU, for obvious reasons. If they say the present shambles is not the fault of Brexit, they may just have a point.
Petrol queues will grow for as long as the Press say there is a problem, and garages do not impose a minimum charge.
A few months ago I heard of a bloke trying to return an entire pallet full of toilet paper and claim a £200 refund. Supermarket manager said the product did not appear to be faulty and was eminently suitable for purpose, including wiping egg off the face of an idiot, so no, thanks.

Most military commanders will not reveal tactics in advance.This is policy and strategy, not tactics. JC was a lifelong nuclear disarmer, until the opportunity arose for doing it, thus demoting him to the level of "politician".

the people were known to have changed their minds.To state that 33,000,000 voters have changed their minds is an assertion of psychic power beyond the wildest imaginings of a raving lunatic.
Fortunately we have elections and referenda to eliminate the need for psychics.

The conservatives have trouble swallowing Islam , Labour Judaism.Too simplistic.
All politicians want is votes.
Time was (1930 - 1970) when the Left opposed fascism, the Right supported it, and the Muslim vote was too small to matter, so Labour was distinctly pro-Jewish and the feeling was mutual. Now there are ten times more Muslims than Jews in the UK, and some (say 10%) are distinctly anti-Jewish, so it behoves one party to secure that vote, and the other party to secure the equal number of Jewish votes by appearing anti-Muslim. Since most British Muslims have brown skin, it is logical for the party with a pro-fascist history to take the anti-Muslim line.
It doesn't really matter who you choose as the Enemy Within, but it's easier for the Press and the electorate to support you if they are visually identifiable. Remember Enoch Powell?

So the obvious thing to do - since this is meant to be a democracy- is to ask the people (again).and again and again, until they come up with the right answer. That is indeed the European way.
The problem was not a lack of mandate, but the unwillingness of the government to implement the mandate it had asked for, and the inability of the main opposition party to decide what policy to present to the electorate other than "you choose" - exactly what had got the Tories' knickers in a twist in the first place! Not helped by its leader, who, as PM, would have his finger on the nuclear button but in response to a straight question would not commit either to pressing it or to scrapping it. Two big questions, no answer, electoral suicide.
Here's a different approach (if you are determined to consider the electron as being made of "stuff"). A permananet bar magnet could theoretically be cut into little pieces, each piece turned through 180 degrees and then stuck back together again. The final bar magnet is made of the same stuff but would now have the North and South poles reversed in orientation. So, we can imagine a similar process of re-arranging whatever a electron is made of to obtain a particle where a negative charge has been switched to a postive charge.Beg to differ. A magnet is a dipole composed of a whole lot of dipoles. If you reverse each dipole, you reverse the magnet. The charge on an electron is spherically symmetric - a monopole - so flipping it over might reverse its angular momentum and magnetic dipole moment but won't change its charge.
If the electron were composed of charge dipoles, they would have to be arranged radially in a sphere with their positive ends pointing inwards. So now you need to embed them in some kind of glue to stop them flying apart or spontaneously rotating, which would give the charge a half life that is not observed.

Greek philosopher Democritus assumed that there must be some indivisible particle of matter that he called an "atom". He assumed this with absolutely no physical evidence. (Since the 1900s, we have proof that an atom is made of even smaller things...)The story I was told was that he observed a worn stone step (solid physical evidence!) and argued that
(a) bits of it must have been carried away on people's feet (by analogy with mud or water)
(b) the bits must have been very small, since nobody saw them go (unlike mud or water)
(c) the bits must have been part of the stone
(d) there was no reason to suspect that they had evaporated into nothingness as bulk stone doesn't evaporate by itself
(e) therefore the bits that disappeared must have been stone
(f) hence stone must be composed of invisibly small particles that do not disintegrate - a tomos - indivisible.
A deduction made all the easier if there are only four elements, but like all good hypotheses, it started from what was seen (the stone) and current knowledge (the elements), and was consistent with all other observations.
