Something is wrong

I sense something is wrong because it has been raining incessantly for 3 months now and some districts in the center of Britain has flooded. That is not how winter works here on this island. What normally happens is we get lots of frost in the night and it stays dry and it snows a bit. Even the trees are confused, some of them have opened their spring blossom flowers in February. 

If this is all down to global warming from the greenhouse effect then I would think about Venus because that is a super greenhouse. 

Venus is only about 40 million killometers closer to the sun then Earth but the temperature is 450 °c. To give you a sense of scale, Mars is 220 Millon killometers from the sun, twice as far as Venus. If Venus was in Mars' orbit it would still be over 220 °c on the surface, more than twice the boiling point of water. Even if Venus was placed in the orbit of Jupiter it would still be too hot.

Venus would still be slightly hotter than Earth at the surface if it was as far from the sun as  the planet Saturn. The atmosphere of Venus is very thick so it traps more heat and is even hotter than Mercury which is twice as close to the sun. 

It makes me wonder really perhaps a slow burning star like a red dwarf that is dim could have planets with liquid water on them without being tidally locked if the atmosphere was better at trapping heat. Perhaps such a planet would be fine recieving 5% of the sun's energy if it trapped more heat and it could be at Venus' orbit.  Who knows?

Greenhouse nonsense

Many governments around the world think there is a big problem with global warming, I don't. I will tell you why.

I think that global warming is real and is a hazard but I don't think there is enough fossil fuels on Earth to cause a lasting greenhouse chain reaction.

In my opinion, global warming is a problem that is fixing itself. The inconvenient truth is that is is more and more inconvenient to harvest crude oil. It costs more and more money to get oil and coal out of the ground so people are motivated to get more fuel efficient cars and electric cars are getting cheaper and cheaper to make. Solar panels are also getting be cheaper to make.

Oil and coal near the surface is running out so bigger drills and diggers are needed that cost more money to get to the oil that is deeper and more out of reach. Eventually there will be no fossil fuels left.

Why should leaders like President Macron steal money from people to fix a problem that is fixing itself?

First Frost

One of the biggest issues of my time is global warming. Scientists believe that Carbon Dioxide (CO2). Is reflecting some of the heat energy from the sun back towards the Earth's surface. I don't think it is a big issue and I will tell you why.

I make my own crude observations, I see if the first frost comes before daylight saving or after. This year the first frost came one day before daylight saving. My car was covered in frost one day before daylight saving time changes, so the cold period is on time.

After all these years of emitting so much carbon dioxide, I can't see the problem, I mean surely most of the fossil fuels have already been used up and we will run out before there is a runaway greenhouse effect. Perhaps the ice caps will melt and cause global flooding. I don't know but everything looks normal here for now.

I learnt last night at about 2am that Charlie Kirk was assassinated by a lone sniper purched on a rooftop. I felt a deep sadness for his dea...
