The Fight against Global Warming and what can be done. Slow the pace of climate change through agriculture has been proven by a California University. Low-tech ways of improving soil quality on farms and range-lands worldwide. The study has proven that the rising temperatures around the world could be reduced by seeding the grasslands with carbon eating plants.
The researchers found that well-established agricultural management practices could do it. Planting cover crops, optimizing grazing and sowing legumes on range lands. If instituted globally, could capture enough carbon from the atmosphere and store it in the soil to make a significant contribution to international global warming targets.
Their initial aim was to determine if such practices could reduce global temperatures at least 0.1 degree Celsius (0.18 degrees Fahrenheit). This is one-tenth of the Intergovernmental Panel on Climate Change’s goal. Limiting the average global temperature increase between now and the year 2100 to 1 degree Celsius (1.8ºF), or 2″ degrees Celsius (3.6ºF)” above temperatures before the industrial revolution.
When combined with aggressive carbon emission reductions. The best scenario for limiting warming from climate change. The study found that improved agricultural management could reduce global temperatures 0.26 degrees Celsius. Nearly half a degree Fahrenheit by 2100.
Will sequestration in soils make a difference with climate change at a global scale? We found that there are a wide range of practices deplorable on a large scale that could have a detectable worldwide impact. A big take-home message is that we know how to do this, it is achievable.
Hope for Climate Change
By throwing in biochar, a controversial soil additive essentially charcoal obtained by burning crop residue in an oxygen-free environment. These practices could offset even more warming, potentially as much as 0.46 degrees Celsius (0.7ºF). The caveat is that this is only achievable if you couple sequestration with aggressive emissions reduction. If carbon concentrations increase in the atmosphere, then sequestration becomes less effective at reducing temperature. We would have to pull much more carbon out to realize the same reductions. She and her colleagues, including lead author Allegra Mayer, a UC Berkeley graduate student, will publish their findings Aug. 29 in the online journal Science Advances.
The IPCC has established carbon-reduction goals to limit average global warming in 2100 to 2 degrees Celsius (“3.6°F” ) above global average temperatures before the industrial revolution, or about 1760. Earth is already halfway to that limit, having warmed 1 degree Celsius since 1880.
Increasing Food Production
Not only was the study revealing a drastic decrease of carbon in the atmosphere through soil management a major increase in soil quality would also be realized. This would lead to a massive increase in the quality of world food production. Higher crop yields pulling even more carbon out of the atmosphere. The point of the paper was to look at the temperature effect of implementing existing low-tech technologies already practiced within agriculture, in developing as well as developed countries. There could theoretically be an immediate and widespread adoption of many of these practices.
With aggressive emissions targets, improved land management could pull about 1.78 petagrams of carbon from the atmosphere each year, while adding biochar to the mix could raise the yearly sequestration rate to 2.89 petagrams. So one petagram is equal to one quadrillion grams, or one trillion kilograms. That is a lot of carbon being taken out of the atmosphere through agriculture.
Turning the Villain into the ally
Agriculture is often portrayed as the villain in climate change. What is exciting in the study is that agriculture can now be used to solve the problem. Rain forest devastation has often been seen as a major contributor to the weird weather the earth has been seeing lately. Now with new improvements to world wide agriculture methods it can now be turned into the savior of the planet.

Solutions are there
Simple practices like changing our driving habits and improving our soils could easily turn the tide of climate change. The war on climate change has just begun. It is going to be a long and bitter war. Already in forest covered provinces like B.C. Canada and drought inflicted states like California fires are raging. Fires are raging out of control across thousands of hectares, destroying everything in their path. What is causing these fires? We have never seen anything like this before.
So, while you should be concerned about the growing frequency of wildfires and their attendant effects on global warming, don’t lose too much sleep over the issue. There is a limit, the Lantern presumes, to how much anxiety you can sustain. It might be best if you conserved your angst for more readily tackled issues, such as our appalling fossil-fuel dependence.
Carbon Dioxide Emissions: Human Sources
Since the Industrial Revolution, human sources of carbon dioxide emissions have been growing. Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.
87 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil. The remainder results from the clearing of forests and other land use changes (9%), as well as some industrial processes such as cement manufacturing (4%).1
The Melting of the Ice Caps
The worst scenario of climate change just could be the melting of the ice caps. Planets like Mars have gone through similar changes billions of years ago and the outcome is not pretty. Rising oceans would devastate the coastal regions around the world. Unfortunately a lot of the agriculture land along the fertile rivers would be flooded. Millions of acres of food supplies would be gone.
Alarmed, you should be. Sometimes it takes a little alarming to wake people up to the fact that climate change is here and it’s real. The greedy oil cartels of the world have no intention of giving up their trillion dollar industry to save you. They don’t care if you drown or starve. It would be good for the planet to get rid of most of the population. Only one thing can save yourselves and that is you. Every one of us must take control and fight the oil cartels. Who do you think rules the world?
