"Who is to say that the earths natural state means ice caps "
There is no one "natural state" of the Earth as we know from geological history. Anyone who thinks the temperature of whatever year is what global temp. "should be" is denying climate changes naturally and is thus a climate change denier.

In reality the global warming scam is a political project dressed up to look like science in an attempt to make it beyond question. The number of objective scientists in this field can probably be counted on one hand. They've all got their nose in the trough or are campaigning for a ideaological "cause" to save the world.

The Earth has been cooling gradually for the last 8000y , a slight recovery on that slippery slope is certainly not a problem we should spend a lot of time or money worrying about.

You are quite right about meteor impacts , the last near miss: 2019 OK passed 70,000 km in front of our planetary nose. Considering we are moving at 30,000 km/s that means we just missed a direct hit by less than 2.5 seconds !! Take minute for that to sink in.

If you want a "moon landing" sized effort to save that planet, it seems that is a more serious risk than 0.7 deg of warming in 100 years !
