How is climate change a problem when the earth has gone through periods in the past where the poles became tropical?

Climate change is no problem……………………..At least: for the earth.

The earth will continue to exist, but there will undoubtedly be plant and animal life.But whether humanity survives is not so certain, and undamaged it will certainly not come from it. The current rapid warming is caused by human action and if we want to prevent people from getting into trouble we will have to do something like humanity.

These periods have been there, but there were no people yet.Global warming is in the first instance a problem for and by people.

Of course it is also a problem for the animal species that are threatened in their existence, but such extinction events (where more than 90% of all existing animal and plant species die out) has already experienced the Earth five times before, And every time she has come on top.Although the extinction is now far faster than in the other events, thanks to man.

But well, the earth will come above the global warming again, it is only the question of whether humanity will survive it.Currently, some 80% of the world’s population live in areas that will suffer from rising sea levels, 40% won’t be within a 60 kilometer radius of the coast. Three-quarters of the world’s largest cities are located by the sea. [1 Those people will all have to migrate, and just count that this will take care of conflicts.

In addition, an increasing proportion of the fertile soil is affected by soil erosion and pollution from wrong agriculture and forest, which means that we have to feed more people with less than a country (because the world population is still growing).

By melting glaciers and snowtops, the disappearance of large water depots such as the Aral Lake, and the ever-increasing and extreme droughts in many parts of the world, a percentage of the available fresh water is also disappearing every year on the World.This comes into the sea, but it is very expensive and time-intensive to make saltwater usable fresh water, which is simply not possible on a large scale.

But yes, it is therefore a problem for humans, because of the threat of habitat, possible future conflicts, soil erosion and resultant desertification, disappearing freshwater springs, decline in biodiversity, etc.

Oh and then I have not even heard about the ancient viruses stored in the now defrosted Permafrostlayer, such as anthrax and the Plague[3, which have now both been signalled again, and the further spread of tropical diseases now the animals that Spreading in many more places can survive thanks to a warmer climate.

Well, but the earth will come on top of it, man might not.

We will probably not be experiencing the worst of them, but it is a problem for future generations.

Normally there was a cycle of hot and cold periods for millions of years:
Warmer climate-> More plants (trees in particular)-> more carbon dioxide is converted into oxygen-> Greenhouse effect decreases-> colder climate-> fewer plants-> less carbon dioxide is converted into oxygen-> Greenhouse effect Strengthened-> warmer climate.
The problem is that this is now too fast and unnatural.Far too much carbon dioxide comes into the atmosphere much too quickly, more than the trees can take on. And now that we are talking about the trees, that is another thingy where it goes wrong now. Normally more trees would grow when the earth heats up, but many more trees are cut down than planted, so we can no longer go back to the colder climate unless we change it.
