What should the ideal average temperature of the earth be?

The temperature of the earth is going to be what it is, no matter what people do.

That makes it kind of pointless to even discuss what it ought to be.

We are incapable of changing the temperature, but we're very capable of adapting to changes int the temperature... so you really have no worries. (People live in hot African deserts and in places that are mostly covered with ice. We'll be fine, really.)

The global average temperature has never in the history of the world been stable. Right now the earth is not as warm as it was during the Cretaceous and we are not as cold as it was during the last ice age. There is nothing constant in this world, so get over it.

The only thing ever stable about the earths climate is that it has for the last several million years spent more than 80% of the time in ice ages and a little more than 10% of the time in warm interglacial periods. Because of this the liberals feel that the world warms up when man sins and so to cool the world off and save it from hell all moderates and conservatives must either convert to liberalism or die. They tried this several hundreds years several places in Europe and it failed miserably except several million non believers in liberal politics were executed by the liberals for sins against god, it was called the inquisition.

good question. Why do they spend so much time and money on it? Perhaps because the money isn't being used for the purposes the claimed it would be used for.

I agree with dana, a stable one, like one in which you would only see a <1 degree temp rise in 100 years. Oh wait, we have only seen a <1 degree temp rise in 100 years.

for our current biosphere, the current temperature range is best. if the climate changes faster than organisms can evolve, or move, to compensate, then a mass extinction occurs.

The ideal temperature is a stable one.

The species living on the planet, including humans, are adapted to the current climate. Migratory patterns are based on the climate being relatively the same from one year to the next.

Once you start rapidly changing the Earth's temperature and climate - which is what we're doing - that's when problems arise. Change it too fast, and species can't adapt.

I don't know of any efforts to regulate it, just mass efforts to avoid ruining it, with or pollution.

72 degrees would be nice.

People spend the money because it is political.
