Will there be a snowball effect? (lol)

Really... As the Earth is still warming up from the last glacial epoch and will continue to do for at least another millennium, this is entirely to be expected. I am typing this in a location that only around 10,000 years ago was under a kilometre of ice, in a landscape now composed of U-shaped valleys, hanging valleys, moraine dams, drumlins and liberally sprinkled with erratics. all of which are the result of the glaciers receding. Now, that was some climate change that caused THAT, and not a single SUV or airliner anywhere in sight!

Nearly EVERYTHING will be different in 100 years though few living today will be here to make observations. The past 200 years especially has seen ever accelerating rates of change and we are far closer to the beginning than the end. Most of the land above sea level is concentrated at higher latitudes in the N. Hemisphere so shorter less severe winters are definitely prospective if such predictions as above are borne out.

Climate naysayers often claim that "climate is always changing" – but in fact climate only changes in response to climate forcings. Scientists have long identified those forcings - some force cooling, some warming - and the biggest impact is from manmade CO2. So while exact modeling is hard there simply are no hidden forcings lurking to jump out and massively reverse the trend. And by the way: two standard deviations away from the average is not something you often get - except maybe for cancer growth.

So who is going to get China to curb their CO2?

Catweazle, you need to read Earth's Shifting Crust by Charles Hapgood, where you will discover that at the time of the last so called "Ice Age", the north pole was located in Hudson Bay; that there is evidence that these shifts are a regular feature caused by disturbances in the rotational dynamics of the planet. Hapgood implied that the next movement was going to bring New York to the equator; except that recent analysis of data from GRACE https://www.jpl.nasa.gov/news/news.php?feature=6332 shows that that movement has stopped and now the north pole axis is accelerating towards the UK. Every day brings something new to learn.

No matter how you spin it....Human Kind will adapt! We have had thousands of years of climate changes which have caused famine and displacement in where we live. And yet, here we are! We will continue to adapt to the changes before us, or, we will die as a species, and I don't see that as a option.

Not to worry. We (humans) will die before humans can kill the earth.

That means that it will soon be back to where it was before the ''little Ice Age'' commenced. So, no real difference from its historical state, when the Northwest Passage was normal. How anyone can still cling to the ''CO2=global warming'' myth, is beyond me, but then loads of people still believe in mythical gods. Human produced CO2 is just a miserable 10% of the total, so even if humans reduced their CO2 output to zero, it wouldn't change much. [To achieve that they would all have to stop breathing! :-))]

Worzel, you'd only have to stop breathing if you killed all the plants. There's this thing called photosynthesis...
