A ton of climate change wisdom in just two sentences !

Today's temperature is colder than most of the last 10,000 years. 

 

I  like to compare today's temperature with the Little Ice Age centuries, which were coldest in the 1690s.

 

Since then, there has been 325+ years of intermittent global warming.

 

Unfortunately, the global average temperature is just a rough estimate before the use of weather satellites in 1979. 


So I can't say exactly how much warming since the 1690s -- certainly over +1 degree C., and probably +2 degrees C.

 

I should more often mention the late 1600s and early 1700s were the coldest period of the last 10,000 years.

 

Two sentences near the end of a new article (today) by two geologists on historical climate reconstructions were brilliant. 

 

While climate reconstructions, using climate proxies, are real science, they are very rough estimates of past temperatures and CO2 levels.

 

Climate proxies, such as Antarctica ice cores, tell us the climate of our planet has always been changing, long before humans began burning fossil fuels.

 

It's a long article, but near the end I found these two sentences:

 

"The supposedly "four warmest days on record" have occurred only about 300 years after the coldest century of the past 100 centuries. 

 

This could only be described as a “climate crisis” or “climate emergency” by someone who was unversed in the basic scientific principles of Quaternary geology and signal processing."  

 

And here is one of the charts from the article:
