CNN just put out a story titled There is more CO2 in the atmosphere today than any point since the evolution of humans. The article stated:

According to data from the Mauna Loa Observatory in Hawaii, the concentration of CO2 in the atmosphere is over 415 parts per million (ppm), far higher than at any point in the last 800,000 years, since before the evolution of homo sapiens.

The article went on to describe just how bad life is going to be when the planet is only 2 degrees warmer then current temperatures. If you are paying attention we are already clearly seeing signs of this.

I suggest reading the full article. Perhaps the strongest point is the finish that stresses:

We are running out of time to avoid a world that we literally do not know how to handle.

I couldn’t agree more.
