You appear to be familiar with Earth's climate history. Can you please tell me the last time Earth's climate has changed so
rapidly?
Typically, the transition from an ice age to an interglacial period (peak warming) takes several thousands of years. This gives established ecologies of plants and animals many hundreds of generations to gradually adapt and migrate north during trends of warming, and south during trends of cooling. Climate change is actually an important factor in the evolution of species -- but only if it occurs slowly enough.
In the last 100 years, we've seen roughly 4,000 years of climate change. Not only is this too rapid for our forests to adapt (the migration via seed is, after all, a slow process) -- but our sprawled cities, highway infrastructure, and agriculture has taken up so much available land that there is simply
no path for these ecologies to migrate.
Of course other forms of pollution are important -- but the issue of too high a concentration (too quickly) of greenhouse gases is translating into the death of the planet's system of filtration.
We've all been contributing to this problem our entire lives. It is a long-term problem that is impossible to solve overnight; however, if we don't commit to it
now then it will be impossible to solve, period.
