This is a brief summary of what geoscientists and climate researchers Dr. Peter Köhler and Dr. Gregor Knorr from the Alfred Wegener Institute found.
‘One of the most abrupt rises in the carbon dioxide concentration in the atmosphere at the end of the last ice age took place about 14,600 years ago. Ice core data show that the CO2 concentration at that time increased by more than 10 ppm (parts per million, unit of measure for the composition of gases) within 200 years. This CO2 increase, i.e. approx. 0.05 ppm per year, was significantly less than the current rise in atmospheric CO2 of 2-3 ppm in the last decade caused by fossil fuels.’
During a critical period in the world’s climate when the permafrost was melting naturally and releasing CO2 at the maximum rate it increased by 10 ppm in 200 years and we can do that in 5 years.
The human lifespan is relatively short in world terms but even so we are seeing changes within our lifetime. The next thirty to fifty years should see some big changes and many of them will be unexpected.
Weather is only the local expression of the climate and we are making huge changes to the climate. Expect some huge changes to the weather.
Two recent reports on normally reliable blogs are so extreme that I have to question their validity but will pass them on because they sound credible and even if they are found to be short lived, we can expect similar unexpected events.
Just as we were not expecting the jet stream to slow down and bring big changes to the weather in the northern hemisphere so other events will come out of nowhere.
The first by Robert Scribbler shows how Greenland has created its own cold wind circulation because the North Pole is so warm that it has become dysfunctional and so the extreme cold of the high Greenland plateau has taken its place.
it’s just one of those events that everyone keeps looking for because it has happened before and may happen again.
