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

‘Chunyun’ Madness: World’s Largest Human Migration

Posted by feww on February 5, 2015

3.74 Billion trips in 40 days!

China’s Spring Festival, “Chunyun,” began on February 4 and will last until March 16, a 40-day travel frenzy period surrounding the Chinese Lunar New Year, which falls on February 19 this year.

The world’s most populous country is expected to make billions of trips during the 40-day Chunyun madness, 3.4 percent higher than last year.

In 2014, 3.62 Billion passenger trips were made during the spring madness.

Calculated at an estimated average carbon footprint of 100kg of CO2 per passenger trip, the Chunyun journeys will have produced a total of about 374 million metric tons of CO2.

China’s per capita CO2 emissions was 7.2 metric tons in 2013, surpassing the European Union in pollution levels [per capita 6.8 tons in Europe, 16.4 tons in the U.S. and 1.9 tons in India,] according to a study conducted by the Tyndall Center and the University of Exeter’s College of Mathematics and Physical Sciences.

The researchers projected global emissions would rise by 2.5 percent in 2014 to a record total of 40 billion tons.

Image of the Day: F*** OFF Coal Pushers

Direct action seems to be the only way to tackle soaring carbon emissions —Climate Scientist

“The first action that people should take is to use the democratic process. What is frustrating people, me included, is that democratic action affects elections but what we get then from political leaders is greenwash.

“The democratic process is supposed to be one person one vote, but it turns out that money is talking louder than the votes. So, I’m not surprised that people are getting frustrated. I think that peaceful demonstration is not out of order, because we’re running out of time.” James Hansen, NASA climatologist, said.

Corporate lobbying is undermining democratic attempts to reduce CO2 pollution. “The democratic process doesn’t quite seem to be working,” he said.

Pump, Pump, Pump Up the Volume!

Posted by feww on September 27, 2008

All CO2 Stats are Shooting Up!

Up goes the annual mean growth rate of atmospheric CO2 to 2.2 ppm for 2007.

  • Growth rate for 2006 : 1.8 ppm
  • Average rate for the period 2000-2007 : 2.0 ppm per year
  • Annual mean growth rate average for 1977-2007 :  1.5 ppm per year
  • Atmospheric CO2 concentration (2007) : 383 ppm  (37% higher than the preindustrial revolution levels of about 280 ppm (1750)
  • Current concentration of atmospheric CO2 is the highest level probably in the last 20 million years
  • Anthropogenic CO2 emissions have been growing about four times faster since 2000 than during the previous decade
  • Emissions from the combustion of fossil fuel and land use change almost reached the mark of 10 billion tons of carbon in 2007
  • Anthropogenic CO2 emissions are growing x4 faster since 2000 than during the previous decade, exceeding the worst case emission scenario of IPCC
  • These changes imply a more critical impact on climate and sooner than expected

[ppm: parts per million]

Note: Based on FEWW calculations, the anthropogenic CO2 Emissions for 2007 almost reached 10.38 PgC.


Emissions increased from 6.2 PgC per year in 1990 to 8.5 PgC in 2007, a 38% increase from the Kyoto reference year 1990. The growth rate of emissions was 3.5% per year for the period of 2000-2007, an almost four fold increase from 0.9% per year in 1990-1999. (Source: Carbon Budget 2007 – Global Carbon Project).

[PgC: Petagrams of carbon. To convert to CO2 million metric tons, MMT, divide C figure by 12 and multiply by 44; e.g., 1PgC  is the equivalent of 3,666.67 MMT of CO2.]

350 or 450ppm? Neither, Actually!

Posted by feww on June 18, 2008

Submitted by Dione, CASF Member

What would the future be like for my daughter?

Don’t know much about history
Don’t know much biology
Don’t know much about science books
Don’t know much about the French I took
But I do know that I love her

What a wonderful world this would be

Don’t know much about geography
Don’t know much trigonometry
Don’t know much about algebra
Don’t know what a slide rule is for
But I know that one and one is two

What a wonderful world this would be

[From a Herman’s Hermits song, Wonderful World, lyrics by Cooke/Alpert/Adler. Lyrics may be subject to copyright. See FEWW Fair Use Notice!]

Creating A Sustainable Future (CASF) received an emotional email from a young mother, “Kay,” who wishes to remain anonymous. Kay has a 6-year-old daughter and lives with her family in NW United States. Kay says she is not high on science, “in all probability the Herman’s Hermits famous song, ‘don’t know much about history, biology, science books, geography, trigonometry, algebra, and slide rule’ was written about me!”

She says her knowledge of climatology is even poorer than her French(!) “But I do know that I love my daughter and husband and ‘what a wonderful world this would be’ if we could rein in the greenhouse gases, and reverse the global warming.”

“I have read a number of articles about CO2 pollution in the atmosphere including a few written by the famed NASA scientist, Dr J. Hansen … but he is a government scientist …”

She wants to know the safe level of CO2 in the atmosphere and asks which of the 350, 450, or higher levels of CO2 pollution would be a “safe” level, and whether our reply could be put simply so that a “layperson” could understand the answer.

Hi, Kay – thanks for visiting our blog and email!

The CASF members believe even the lower atmospheric CO2 levels of 350ppm CO2 are unsafe! Here are the reasons why. Our findings put as simply as we could:

  1. Our climate models show that when the atmospheric CO2 levels leaped over the 330ppmv “threshold” in the mid 1970s it triggered a positive feedback loop, which is now impacting the climate. [The atmospheric CO2 inventory has risen by about 17 percent since then.]
  2. The “acid test,” if you’ll excuse the pun, of the accuracy of our models lies in the future, namely how much worse the environmental impacts will be in the 2008-2010 period. If the impacts of CO2 pollution worsened significantly, by a factor of 20% or more, by 2010 (we have a system for quantifying the adverse effects, see Index of Human Impact on Nature for an introduction), as we expect them to do so, then we know our models are accurate.
  3. The catch? By 2010 it would be too late to do anything to slow down the runaway positive feedback system [other than say a prayer for the dead!]
  4. While the preindustrial levels of 260-270ppm were [and they probably still would be ] “safe,” the longer term environmental impacts of CO2 at levels of about 290-300ppm, even if those levels were achievable [assume some miraculous means were introduced to wipe the slate clean,] in the current climatic state are uncertain!
  5. Based on the above, we recommend an immediate shift to zero-emissions, the benefits of which, although by no means immediate, would far outweigh the ultimate cost of playing Russian roulette with climate change.

We hope the above helps. Feel free to visit us anytime!

Best wishes
Dione, FEWW Moderators and rest of CASF Team
