What have people learned from global warming?

Answer 1

Not much, I'm afraid. We know what causes it, burning fossil fuel, but we won't stop burning it. Governments know this, but they are only interested in getting re-elected and not disturbing the economy. There are no great statesmen and women who are looking fifty years ahead.

We know that cutting down trees means that more carbon dioxide is left in the atmosphere, but we still cut down trees, all over the world.

We can see the pine forests of British Columbia destroyed by the pine beetle, because winters are now not cold enough to kill it. We see all this, but we do nothing!

Answer 2

People have learned that global warming is primarily caused by human activities, such as the burning of fossil fuels and deforestation. It is leading to rising global temperatures, more severe weather events, melting ice caps, and rising sea levels. This knowledge has spurred efforts to reduce greenhouse gas emissions and transition to more sustainable practices.
