That's wishful thinking.

Take the Earth and the Moon which are the same distance from the sun.

The Moon's average temperature is about -50C - that's minus 50. The Earth is a lot warmer because it has greenhouse gases to keep the heat in.

Greenhouse gases do actually work. Now if you double the amount of carbon dioxide in the atmosphere through burning fossil fuels what do think is going to happen?

More heat will be trapped as greenhouse gases increase of course. It's not a political thing it's simple physics.

But CO2 levels have gone from pre-industrial level of 228 to over 400 parts per million just recently and they are still rising. They've not been that high for millions of years.

You may not be able to predict what's going to happen but last weekend's flooding may be the sort of nasty outcome that will become more common as more and more heat is trapped and has to be dispersed from the equator to the poles.

This is definitely the kind of thing we might expect as this additional energy is dispersed - stronger winds, wetter weather in some places, droughts in others - California comes to mind - even the freezing cold winters of a few years back here in Castlebar when the polar vortex decided to pay us a visit are all likely to be part of this climate change brought about by 400 ppm CO2 in the air you breathe.
