The globe has been warming for over 250 years at a rate of 1/4 deg C per century.
Yet the experts say that by 2050 temperatures will rise by 1.5 to 2.0 deg C.
What will cause this this 6 to 8 times rate increase in global temperatures?
The false suggestion is that CO2 levels are rising quickly, and that this is the reason why temperatures will rise rapidly.
CO2 is <1% of our atmosphere, so it doesn't take much to alter this. However the major sources of CO2 are not manmade. The sea, volcanos, animals etc make up the majority of CO2.
Also CO2 is not a "greenhouse gas" as claimed. Instead CO2 increases as the sea warms up, ie it is an effect of global warming, not the cause.
What's the cause? The best explanation is solar activity. Our sun is one of the most stable in the universe, but that does not mean it is totally stable. It appears to have medium term and long term cycles, but is on the upward part of a LT cycle currently.
Is the Earth hotter than its ever been? No it was hotter in the 1500s apparently.
We don't bother about global warming because we live in a created world that is designed not to overheat.
Manmade global warming is a big deception.
