Global Change and Politics

It’s hard to get the general public to grasp the vast size of our carbon problem, that we will not only have to stop emitting carbon dioxide into the atmosphere BUT ALSO find a way to pull vast amounts of CO2 already in the atmosphere and put the carbon genie back in the bottle.

Pick a reason for forgetting about our grandchildren who will all be living in a new world of Global Change: Ignorance; Greed; Denial; Tribalism (following the group thinking); Short-term Thinking.

Carbon GenieAt least half of our wise leaders don’t even see our carbon emissions as a serious problem. Very few leaders will support any change because no-one in power wants what would disrupt the cosy status quo.

Here are the facts: the U.N. Intergovernmental Panel on Climate Change (IPCC) estimates that a massive amount of CO2 removal will be required this century — at least 500 billion metric tons pulled back out of the air — if we are to avoid the worst of global warming. 

There is no current magical technology to absorb all the harmful CO2 in our atmosphere. But there’s worse news. There are almost no business cases for carbon removal right now. In other words, it still costs nothing to spew CO2 into the sky, so people have no financial incentive to stop dumping, let alone pay to clean up the air.  At the very least that we can do now is to require a price to be put on CO2, making it more expensive to emit.


Nature is our untapped solution. Tropical forests are incredibly effective at storing carbon – providing up to 30% of the solution towards climate change. Despite this, nature-based solutions only receive 2% of all funding devoted to climate solutions.

What we need is a Marshall-style construction programs, and an acknowledgment that we have to escape failed paradigms. 

We don’t have the luxury of a lot of time: the best science says we have less than 10 years to reduce carbon emissions by at least 90% if we expect civilization to deal with the possibility of extreme global warming.

The irony is that it will take far more funds to recover from carbon dioxide in the atmosphere, if we decide to wait to act. The cost and consequences of inaction are too high to risk.

Hopefully, it will not take a climate catastrophe to motivate such action, such as the drowning of some coastal city like New Orleans.

What are we to do?

Reforesting the Tropics 2

Saving Humanity: Reforest the Tropics

Buying Time to develop alternative technologiesReforesting the Tropics

Planting trees remains one of the most cost-effective means of drawing excess CO2 from the atmosphere. Therefore, reforesting the tropics will act as carbon sinks, alleviating the greenhouse effect. There are millions of acres of tropical pastures available. When given proper care, orchard tropical trees bear fruit up to 50 years or more.

Reforesting the TropicsPLANT MORE TREES around the world — because… trees are carbon storage (sequestration) experts.

The United States has cut down over 50% of its original forests in the last 400 years, which would have absorbed 50% of its carbon emissions. Once carbon dioxide goes into the atmosphere it stays there for a long time. About 33% continues to cause damage after 100 years.

 It is estimated by the U.S. Forest Service that all the forests in the United States, combined, sequestered approximately 309 million tons of carbon each year from 1952 – 1992, offsetting approximately 25 percent of human-caused emissions of carbon during that period in the United States.

The world’s forests remove over one quarter (27%) of current annual human carbon emissions from the atmosphere each year, the equivalent of about 2.4 billion tons of carbon according to the latest published scientific research.

Reforesting the TropicsThe tropical zones of the world seem particularly attractive for forestation because of the high rates of productivity that can potentially be attained there, and because there appear to be large areas of land that would benefit from tree planting.

Reforesting the Tropics


Young trees absorb CO2 at a rate of 13 pounds per tree each year. Trees reach their most productive stage of carbon storage at about 10 years at which point they are estimated to absorb 48 pounds of CO2 per year and one acre of trees absorbs 2.6 tons of CO2 every year.

 For every ton of new-wood growth, about 1.5 tons of CO2 are removed from the air and 1.07 tons of life-giving oxygen is produced.


Borial zone trees absorb 0.5 Pg C/yr compared to Temperate zone trees at 0.7 while tropical trees grow at the rate of 1.3 or 185% more efficiently year-round than trees in a temperate zone

Younger and faster growing orchards generally have higher annual sequestration rates and they are given higher personal care of proper fertilizer and water: add a further 25% increase. We conclude there is an additional (185% + 25%) or 210% increase in the value of CO2 absorption.

Reforesting the TropicsThis map shows solar-induced fluorescence, a plant process that occurs during photosynthesis, from Aug. through Oct. 2014 as measured by NASA’s Orbiting Carbon Observatory-2. This period is springtime in the Southern Hemisphere and fall in the Northern Hemisphere. Photosynthesis is highest over the tropical forests of the Southern Hemisphere but still occurs in much of the U.S. Grain Belt. The northern forests have shut down for the winter.

 Commonwealth Scientific and Industrial Research Organisation (Australia), CSIRO forests researcher Dr Canadell estimate that tropical forest re-growth is removing an average of 1.6 billion tons of carbon per year. Combining the uptake by established and forest re-growth plus emissions from deforestation, the world’s forests have a net effect on atmospheric CO2 equivalent to the removal of 1.1 billion tons of carbon every year. Reforesting the TropicsReforesting the Tropics

In terms of cutting emissions a 53% reduction in 2010 emissions is equal to almost 20 Gt of CO2 emissions. For some perspective, global emissions from coal fired electricity generation were about 9 Gt CO2 in 2010.

Reforesting the TropicsThe larger predictions from climate models are due to the fact that, within these models, the more important greenhouse substances, water vapor and clouds, act to greatly amplify whatever CO2 does. This is referred to as a positive feedback. It means that increases in surface temperature are accompanied by reductions in the net outgoing radiation – thus enhancing the greenhouse warming. … Satellite observations of the earth’s radiation budget verify this fact.


Moisture created by the rain forests travel around the world. America’s Midwest is affected by the forests in the Congo which is roughly a distance of 6000 miles. Moisture from the Amazon falls as far away as Texas.
