It's Going To Be A Bumpy Night!
By Ernest Stewart
Scientists at the European Commission released a paper describing evidence that confirms humans are causing global warming. Just the latest in about 10,000 scientific papers on the subject. You oldies may recall hearing about global warming way back on the first Earth Day in 1970?
Many in the science community sees climate change as a major threat for humans in the near future. The European Commission Joint Research Centre released a study last week with evidence that confirms that global warming is caused by humans.
A new statistical technique, analyzing data records since measuring started 150 years ago, independently confirms that man-made carbon dioxide (CO2) and methane (CH4) emissions have led to global warming, according to a JRC-led article published on 22 February 2016 in Nature Scientific Reports.
The analysis also shows that the biggest consequences of such emissions are being felt in localized regions around the globe, such as Europe, North America, China, Siberia, the Sahel zone in Africa, and Alaska.
The authors investigated the causes of global warming using a new statistical method for quantifying causality to analyze the relation between time series data on greenhouse gas emissions and those on air temperatures in the last 150 years. The results confirm that recent global warming is mainly caused by increased anthropogenic (man-made) emissions and that further CO2 emissions to the atmosphere will lead to even stronger global warming.
The authors applied the same technique to analyze historical air temperatures and CO2/CH4 data from the past 800,000 years, available thanks to the 30 meter-deep ice core drilled in Antarctica more than a decade ago, offering scientists a clue on a time scale of 800 millennia. They found a causal relationship between temperature increase and rising CO2/CH4 levels, which is the exact opposite of the results for the last 150 years. This also confirms the validity of the technique, as it's well known from the ice core data that in historical times, increase of temperatures had been followed by higher CO2/CH4 emissions. The causality relationship appears to have started reversing around 5,000 years ago. The analysis confirms this opposite trend for the last 150 years, when unprecedented amounts of CO2 started being pumped into the atmosphere in the industrial age.
Looking into the effect of anthropogenic emissions on different regions, the authors found strong causality between greenhouse gas emissions and rising temperatures in Europe, North America and China, where densely populated and industrialized areas have shown signs of strong warming.
On a personal note, I've noticed this year we got about the same amount of water that we normally would get from November to March; but it fell as rain instead of snow at about 90 percent rain and 10 percent snow, just the opposite from my childhood daze. Don't get me wrong; I'm not complaining about our warmer winter here with strings of records falling to the rising temps; in fact, the day I wrote this, we broke another record temperature. However, I wonder what wonders global warming will bring in the summertime? I fear, if it's anything like the last 15 years, to quote Margo Channing, from "All About Eve," you better, "Fasten your seatbelts, it's going to be a bumpy night!"

Thanks for the film & the service!
We get by with a little help from our friends!
So please help us if you can...?
So how do you like Bush Lite so far?
And more importantly, what are you planning on doing about it?
Until the next time, Peace!
