Yes
Almost certainly
Perhaps not but sensible to try

No - Yes climate is changing, but no, nothing in nature is unidirectional.

Minor roll - CO2 nowhere near the most important. Water vapour of course, is THE most significant greenhouse gas at between 36% and 85% of greenhouse effects. No one wants to talk about clouds though.... The focus is always on the number two, CO2. Water vapour though, is by far the number one and it's not even on the agenda.

No - Humankind, especially the democracies, will never change their profligate lifestyle. They will never vote for a lower standard of living. Developing countries are not going to accept a lower lifestyle than the West.

You need to tell NASA then, as they must have it wrong...

"Water vapor is the most abundant and potent greenhouse gas in the atmosphere. "

But maybe that this is symptomatic of the propaganda in play. People have been so convinced for so long by the constant focus on CO2 that they start to defend that narrative, even when the science that created it actually says something different.

"The scientists are right, they know what they are talking about, trust the science"
"The science says water vapour"
"Don't believe the scientists!"
"But...."

The latest bilge is to claim that the hosepipe ban is necessary because of climate change.

No, the hosepipe ban - taking this policy response at face value - is because of concerns about the supply of water.

This is partly a result of a period of dry weather conditions, in certain parts of the country. However, there have been drier years than this on numerous occasions over the past century, and these did not lead to bans on the use of water.

So what is different now?

It rains.

Next someone will tell me hydrogen is no good as a replacement for diesel.
