NOAA Warns Record High CO2 Concentration: Global Warming Will Worsen Updated in October 2018
A report by NOAA (United States National Oceanic and Atmospheric Administration) announced that 德赢vwin登录 average atmospheric concentration of carbon dioxide, 德赢vwin登录 major cause of global warming, reached an all-time high in 2017. 德赢vwin登录 report also points out that 德赢vwin登录 temperature of land surface and sea level are both on 德赢vwin登录 rise, indicating that global warming is actually worsening.
In 德赢vwin登录 report titled “State of 德赢vwin登录 Climate in 2017,” 德赢vwin登录 average atmospheric concentration of CO2 was 205 ppm (1 part per million amounts to 1/1,000,000) in 2017. In comparison to 德赢vwin登录 past 38 years, it was 德赢vwin登录 highest. 德赢vwin登录 average temperature of 德赢vwin登录 earth’s surface for 2017, including both land and sea exceeded 德赢vwin登录 annual average temperature data for 1981-2010 by 0.43 degrees Celsius. Moreover, 德赢vwin登录 average for global sea level in 2017 was 7.7 centimeters higher than in 1993. 德赢vwin登录 report mentions that 德赢vwin登录 world’s sea level has risen by an average of 3.1 centimeters for every 10 years in 德赢vwin登录 past.
德赢vwin登录 report also pointed out that 德赢vwin登录 largest Arctic sea ice was 25 % smaller than 德赢vwin登录 average figure obtained from past records, and that sea ice in Antarctica had shrunk to 2.1 million square kilometers. This is 德赢vwin登录 lowest figure since 1978, when satellite data-collection first started. In 2017, 德赢vwin登录 number of tropical cyclones totaled 85, exceeding 德赢vwin登录 average figure of 82 from 德赢vwin登录 periods during 1981-2010.
德赢vwin登录 Paris Agreement, an international framework to prevent global warming hauls a long-term goal to hold global average temperature increase to well below 2 degrees Celsius. To achieve this goal, we must suppress CO2 concentration on at average of 420 ppm worldwide.
In October 2016, WMO (World Meteorological Organization) announced that 德赢vwin登录 average atmospheric concentration of CO2 in 2015 had reached a “hazardous” record-high level of 400 ppm. 德赢vwin登录 NOAA report confirmed that 德赢vwin登录 carbon dioxide concentration is definitely on 德赢vwin登录 rise.
