 Worrisome! The US media says the atmospheric CO2 concentration is high.


The report said that the values measured by the Hawaii nanroya Observatory showed that the gas that caused the climate warming was more than 410ppm on average in April. This concentration exceeded 410ppm for the first time in April 18, 2017, almost a year ago. The report points out that, as the famous serrated curve - its more formal name is the base line curve - it shows that the concentration of carbon dioxide has been rising for decades. But they also fluctuate year by year, which is controlled by the type and seasonality of plant growth in different parts of the world. Ralph Keeling, head of the carbon dioxide project at the Scripps Institute of Oceanography, who is responsible for observing these values, says the increase in carbon dioxide concentration is about 2.5ppm a year. This speed has been rising, and the second ten years of twenty-first Century are rising faster than the first ten years. (the base line was originally named after Ralphs father, Charles David Keeling). This is another landmark event in the process of increasing carbon dioxide concentration, he said of the latest measurements. It brings us closer to some of the goals we are very reluctant to achieve, such as stepping over 450ppm or 500ppm. That would be a very dangerous area. As a scientist, Catherine Hayho, a climate scientist at the Texas Technical University, said, as a scientist, what I am most worried about is not that we have crossed another threshold, but the true meaning of this continuous rise: we are constantly on our side. The earth -- our only home -- carries out an unprecedented experiment. It is reported that atmospheric carbon dioxide levels have reached such levels, even higher, in the history of the earth, but that was a long time ago. Scientists worry that the present concentration is much faster than the rate that the earth used to change. In the middle of the Pliocene about 3 million years ago, the concentration of carbon dioxide had reached about 400ppm, but it was known that the earths sea level was 66 feet higher than now (about 20 meters) or even more, and the earth was warmer than it was now.
