Getting a Better Handle on CO2, NASA Will Help!

From all the news about how anthropogenic emissions of CO2 are increasing tremendously (remember the hockey stick graph?) you would think that these emissions are causing all the atmospheric increases of CO2. And, our use of fossil fuels is increasing exponentially, with more than half of all fossil fuels ever used by humans being consumed in the last 20 years.

However, in comparison with the amount of carbon that enters the atmosphere from natural sources, our fossil fuel emissions are modest. “Carbon dioxide generated by human activities amounts to only a few percent of the total yearly atmospheric uptake or loss of carbon dioxide from plant life and geochemical processes on land and in the ocean,” said Gregg Marland, a professor in the Geology Department of Appalachian State University, Boone, North Carolina. “This may not seem like much, but humans have essentially tipped the balance.”

Scientists are able to accurately measure the amount of carbon dioxide in the atmosphere, both today and in the past, and the impact of our activities is apparent in those measurements. Before the Industrial Revolution, there were about 280 molecules of carbon dioxide out of every million molecules in the atmosphere, that is, 280 parts per million. By 2014, the concentration had risen to about 400 parts per million.

Although we know the concentration of carbon dioxide, much about the processes that govern the gas’s atmospheric concentration remains a mystery. We still do not know precisely where all of the carbon dioxide comes from and where it is being stored when it leaves the air. That information is crucial for understanding the impact of human activities on climate and for evaluating options for mitigating or adapting to climate change.

Scientists expect to get some answers soon to these and other compelling carbon questions, thanks to the Orbiting Carbon Observatory-2, a new Earth-orbiting NASA satellite scheduled to launch on July 1. OCO-2 will allow scientists to record detailed daily measurements of carbon dioxide — around 100,000 measurements of the gas around the world every day.

“Now that humans are acknowledging the environmental effects of our dependence on fossil fuels and other carbon dioxide-emitting activities, our goal is to analyze the sources and sinks of this carbon dioxide and to find better ways to manage it,” Marland said.

“remember the hockey stick graph?”

My first thought was, “Is this guy serious”? That he is only shows that he thinks we’re idiots. Prof. Mann’s hockey stick graph is generally regarded as the most debunked meme in global warming history. He conveniently started it AFTER the Medieval Warm Period turned into the Little Ice Age, and yes, the world has been getting warmer ever since — as worlds often do after ice ages.

If you’re interested in the subject, you’ve got to read this:

And this is even more serious:


I am looking forward to the facts, as actual data gathered, rather than the guessing game we are playing now. Unfortunately we have been terrorized by politics masquerading as science for a long time now. As carbon dioxide is one of the building blocks of life on this planet it behooves us to allow the data to be put together in the scientific process and avoid the use of the completely useless political fearmongering that currently describes the IPCC process.
