John Kerry: "We're on the brink of needing to declare a climate emergency, which is what we really have. And we need to get people to behave!"
The world is in a state of climate emergency, and we need to shift into emergency gear. Humanity’s burning of fossil fuels has emitted enough greenhouse gases (GHGs) to significantly alter the composition of the atmosphere and average world temperature has risen between 1.1 and 1.2°C.

OK So the cause is the world's average temperature as of today:According to current data, the average global surface temperature is approximately 15°C (59°F).
HMMM so how does Kerry et.al. explain the world's temperature 500 million years ago when the CO2 PPM was 4,000?
Concentrations of CO2 in the atmosphere were as high as 4,000 ppm during the Cambrian period about 500 million years ago.

HMMM... who was burning fossil fuels then?
According to recent studies, the average world temperature around 500 million years ago was likely significantly warmer than today, with estimates placing it around 86°F (30°C) or higher, indicating a "hothouse" climate with no polar ice caps and generally high temperatures across the globe; this data is based on analysis of the Phanerozoic era, which covers the past 500 million years of Earth's history.

Hmmm 86° C! Again where was the 4,000 PPM coming from then if we are concerned about
world temperature has risen between 1.1 and 1.2°C.
Would someone please care to explain where did the fossil fuels burning coming from 500 million years ago that caused 4,000PPM and 86°F (30°C) or higher?

The Climate Emergency
The science is clear. The world is in a state of climate emergency, and we need to shift into emergency gear. Humanity’s burning of fossil fuels has emitted enough greenhouse gases (GHGs) to significantly alter the composition of the atmosphere and average world temperature has risen between 1.1...

What's the hottest Earth's ever been?
Earth’s hottest periods occurred before humans existed. Those ancient climates would have been like nothing our species has ever seen.
