Climate change is influenced by humanity, that goes without saying. The basic fact is that all species effect it, a problem occurs when one species effects it too much.
This is usually the result of the population growing out of control, crowding out all other organisms. The ultimate end result is the extinction of that species, not a very pleasant outcome.
Humanity has an added problem, many of our machines double our output of climate changing chemicals. This increase, combined with our population growing beyond tolerable limits, has caused the environment to "tip."
This tipping has begun to destroy environs that we depend on for a more balanced atmosphere, we are eradicating the organisms that can process our outputs into chemicals we can use. By doing this we are causing a huge change in the climate's standard and slowing pattern.
In essence, we are returning the planet to a state before our species could survive. Due to lack of natural pressures, our species is unlikely to evolve to survive that climate.
The arguments against cleaning up our act are all hilariously ignorant of facts. One is "more CO2 means more plants," which is a definitive no.
Increasing the CO2 will not cause more plants to grow, at least not until we move out of the land they need to grow in. Our growth is so fast now that we are encroaching on the last few untouched areas.
When we move into that land, we destroy everything to make room for us. This reduces the plant life to a dangerously low level, so there are fewer plants to process CO2.
I have recently heard claims that CO2 and CO are not dangerous, let that sink in a moment. They have grown so desperate as to deny a fact known for over a century.
A life threatening medical condition known as carbon dioxide poisoning occurs when you inhale too much CO2. Astronauts learn about this as they face the possibility all the time.
Carbon monoxide is worse, it bonds to cells in the lung preventing those cells from absorbing oxygen. Healing from this event has a very high chance of cancer, most causes of CO also produce radioactive particulates increasing the chances further.
Car exhaust carries carbon monoxide well, the particulates keep the gas in a cloud until they fall inert. Any form of burning organic material will create carbon particulates, petroleum is organic.
So is coal, coal is actually concentrated carbon, burning it causes that carbon to bond with oxygen. This can produce carbon monoxide and dioxide, which are currently pollutants because of their quantity in the atmosphere.
There is only one short term solution, replace the lost plants with carbon converters that simulate photosynthesis. This is another huge profit for corporations, assuming we develop them in time.
The only long term solution is to stop population growth and reduce the carbon use. No other solution will have lasting effects, nor will any other solution be sane.
The simple fact of the matter is that we must take responsibility for our use of the planet's resources instead of avoiding accountability.
