Re: When did climate change start then?
You're complaint is understandable as their is a lot of disinformation about.
Yes climate has changed for 4 billion years and the factors include suns output, Milankovich Cycles (earths orbital eccentricities), greenhouse gases water vapor, carbon dioxide, methane etc.
Mostly the first 2 factors have been historically responsible for climate change but they have been exceedingly stable over the holocene (the period humans have existed)
Human induced CC really began in the 1600s when Europe pretty much burnt all the forests for fuel which led to the 1st global energy crisis.
The UK discovered coal and this great energy source led to the industrial revolution.
It was discovered in 1860 that CO2 absorbed heat energy and the first hypothesis was formed that one day CO2 might become a problem.
This effect was studied much through the 1950s as the US Airforce was interested in developing heat seeking missiles and CO2 was interfering with the heat signal.
It was talked about until the late 80s when the atmospheric warming signal began to emerge from the noise which led to governments around the world to start the IPCC to keep us informed of how GW was progressing.
Since the mid 90s it was apparent that we were headed for a problem but modest adjustments to how we sourced our energy would fix the problem.
Nothing has been done since and now we find ourselves on the edge of a global emergency which will really kick in in the next 30 or so years.
If we don't act by 2100 global temps could go up by 6C...
if it does we a seriously talking about a world like Mad Max- no joke!
