Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

GHG Concentrations Hit Yet Another Record

Warming amplified by interaction between CO2 and water vapor: WMO

The concentration of greenhouse gases (GHGs) in the atmosphere continue to set new records.

A 36% increase in radiative forcing due to long-lived greenhouse gases including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) from industrial, agricultural and domestic activities, has affected the climate in the past 25 years, according to WMO’s Greenhouse Gas Bulletin.

The WMO report also highlights the interaction and amplification effect between rising levels of CO2  and water vapour, which is itself a major greenhouse gas, albeit short-lived. Warmer air holds more moisture and so increased surface temperatures caused by CO2 would lead to a rise in global water vapour levels, further adding to the enhanced greenhouse effect.  Further increases in CO2 concentrations will lead to disproportionately high increases in thermal energy and warming from water vapour.

“Every year we report a new record in greenhouse gas concentrations,” said WMO Secretary-General.  “Every year we say that time is running out. We have to act NOW to slash greenhouse gas emissions if we are to have a chance to keep the increase in temperatures to manageable levels.”

[“Manageable levels of temperature?” Is this crotch science or the more scientific “argument of the pubic hair?”]

Atmospheric concentrations of CO2 reached 397.7 parts per million (ppm) in 2014.  “In the Northern hemisphere CO2 concentrations crossed the symbolically significant 400 ppm level in 2014 spring, when CO2 is most abundant.  In spring 2015, the global average concentration of CO2 crossed the 400 ppm barrier.”

Caught in a massive positive feedback loop, Earth’s surface is heating up rapidly. The excess energy trapped by atmospheric GHGs is resulting in increasing levels of water vapor, which in turn generates even more heat.

Atmospheric GHG Break Record

Concentration of greenhouse gases in the atmosphere reached record high in 2010: WMO

The atmospheric GHG rose faster in 2010 than the decadal average.

Disaster Calendar 2011 – November 21

[November 21, 2011]  Mass die-offs resulting from human impact and the planetary response to the anthropogenic assault could occur by early 2016.  SYMBOLIC COUNTDOWN: 1,577 Days Left to the ‘Worst Day’ in Human History

  • Global Mega Disasters. The concentration of greenhouse gases in the atmosphere reached record high in 2010, according to WMO. The atmospheric GHG rose faster in 2010 than the decadal average.
    • Carbon dioxide (CO2) concentration has risen by 39 percent to 389 parts per million (ppm) since 1750.
    • Methane (CH4) concentration has climbed by 158 percent since 1750 to a record high of 1,808 parts per billion(ppb), and up by 5 ppb since 2009.
    • Nitrous oxide (N2O) levels were 20 percent higher at 323.2ppb   than the pre-industrial era.
    • According to the latest Greenhouse Gas Bulletin, the seventh in the series that began in 2004, there has been a 29 percent rise in radiative forcing from greenhouse gases between 1990 and 2010.
    • The atmospheric CO2 rose by 2.3ppm in 2010 compared to 2.0ppm in the previous year and the annual average of 1.5 ppm in the 1990s.
    • “The atmospheric burden of greenhouse gases due to human activities has yet again reached record levels since pre-industrial time,” said WMO Secretary-General.
    • “Even if we managed to halt our greenhouse gas emissions today, and this is far from the case, they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate,” he added.

  • Week of November 13, 2011:     390.32 ppm
  • Weekly value from 1 year ago:     388.40 ppm
  • Weekly value from 10 years ago:     369.79 ppm
