The Earth has been going through ice ages and interglacial warming periods for 4.5 billion years. There is no reason to suspect that this has suddenly stopped.
12.000 years ago the Arctic was free of ice and human interference cannot be blamed for this!
The human effect of 'Global Warming' probably has some effect but the governmental scientists have never tried to explain how much - other than saying it is all our fault.
This is probably because they receive a generous remuneration from respective governments, so why should they ever say anything that would take away their moment of glory and pay package.
For governments it is a very welcome cash cow by way of green levies so why should they admit anything that could reduce these.
Our Sun which is 93 million miles away has controlled the climate of out Earth since it was formed and its sheer power has held us in a tight orbit around it.
When someone can prove that the Sun is not the controlling influence of our climate, I might sit up and listen, but until then any net zero initiatives are virtue signalling and just reasons to raise taxes.
