Global Climate Change

I think we're missing a lot of aspects of contributing factors because it is easy to fight over the two big arguments:
1 - whether it is man-MADE or not
2 - whether CO2 is the cause or not.

Sound is, essentially, the same as heat but at a MUCH lower frequency. Humanity makes a lot of noise. That HAS to have an effect.
Car engines, light bulbs, computers, etc all generate HEAT. It is an undeniable side-effect to what they do. That has to have an effect on things.
Furnaces generate heat. That is their core purpose. That has to affect things tremendously.

Our process of making CO2 generates a lot of HEAT and then traps that heat. It's not just the CO2 but all the things we do (per capita) multiplied by the number of people.

Also - the earth's natural equilibrium is for the northern sore of Canada to be a tropical rain forest. So says the paleontological evidence..... so on top of what we are doing the planet is still recovering from the last ice age to bring itself back to its normal.

In short - unless we figure out how to make the earth's equilibrium match OUR needs or figure out how to move underground / under the ocean - we're screwed on this planet.

200,000 years of human history is nothing next to the 80,000,000 that held the northern tropical rain forests and the 65,000,000 that held the tropical-temperatures around the globe before the impact prior to the Chicxulub impact... and all of the other epics prior to that one were also HUGELY larger than the time humanity has existed and all show the same thing - tropical temperature in the moderate and cold zones of this planet.

Is global climate change happening: yes, absolutely
Did we cause it? Nope.
Are we a contributing factor: certainly.
Are we a significant contributing factor: probably.
Do we ignore a lot of the ways we are contributing: this is as certain as the change itself.
Can we do anything about it: yes, but only if we, as a species, can accept the scientific truths about it and dedicate the resources to modeling ways to change the energy output of our industry and residences as well as figure out a way to properly sequester excess CO2 (secret: there are a lot of simple answers to the latter... some of them are even relatively easy to do).

For starters we need to accept that this is a very complex problem and stop outlining it as simple to the mass populace. We need to stop saying that we know, with certainty, that we CAUSED it. Many of the climate change naysayers are fighting back because they don;t believe humanity is so powerful that we could cause such a problem. Whether this view is ignorant of them or not we can stop their counter-arguments by eliminating the causation argument from the climate-change-is-happening camp.

From there we can focus our efforts on solar and wind technologies like several other "1st World" countries have done. Their usable lands for such energy sources are a fraction of the land available in the US for this and their capture rate is MUCH higher.

We could also engineer our buildings to support rooftop gardens and preserves to reduce the conversion rate of biological heat absorbers and carbon sinks into heat sinks that do not absorb carbon.
We could convert streets in cities into tunnels and cover the roofs of these tunnels with plant-supporting ground to do the same.
We could build buildings that allow for pockets of plants to grow on the sides of the buildings. This would provide additional insulation and further absorb carbon from the air.

These are just some things we could do to lessen our contributions to this problem.
