Sea level rise. As greenhouse gas emissions have increased since the Industrial Revolution, both the earth’s atmosphere and its oceans have warmed. Causes. Since 1880, the average sea level has risen by about 1.6 mm (0.06 inches) per year. However, this rate has not been constant. New research by NASA’s Jet Propulsion Laboratory shows that […]

Are We Facing a Climate Apocalypse? Recently media reports have referred to “apocalyptic” effects of global warming. These headlines remind us of Vincente. B. Ibañez’s novel, The Four Horsemen of the Apocalypse. Set in France during the early days of the WW I, Julio Desnoyers is conversing with one of his neighbors, a Russian named

Carbon Dioxide Removal Carbon dioxide is removed from the atmosphere slowly by natural processes, mainly absorption in earth and plants, but this process takes hundreds of years.It is technically feasible to remove carbon dioxide from the atmosphere mechanically. However, it’s not an economical or practical way to reduce CO 2 in the atmosphere at present.

Global Warming Tipping Points A tipping point is defined as a hard-to-predict threshold beyond which there could be rapid and irreversible changes. Exceeding one or more of many potential tipping points could accelerate global warming and increase weather extremes. The only way to avoid tipping points is to stop global warming. The importance of tipping

Global Warming by Deforestation Deforestation, the destruction of dense forests in the tropics, is a significant contributor to global warming. The countries responsible for deforestation lack the economic incentive and the resources needed to stop deforestation without assistance from the major industrial countries. The importance of deforestation Deforestation reduces the amount of CO 2 that

What does it take to stop global warming? We have to reach net zero, the elimination of man-made fossil fuel emissions. Any emissions that can’t be eliminated have to be offset by the absorption and sequestration of greenhouse gases on earth. This would require an expansion of the earth’s forests and plants that absorb and

How to Reach Net-Zero Emissions? What is Net Zero? Net zero is when CO 2 and other greenhouse gas emissions are reduced to zero so no additional man-made greenhouse gases are added to the atmosphere. Emissions that cannot be reduced have to be offset by sinks such as forests that absorb and sequester CO2, or

October 19, 2020 Should we count on removal of CO2 from the atmosphere to meet global warming objectives? It is technically feasible to remove CO2 from the atmosphere. There are several processes under development. However, there aren’t yet any large industrial plants that could remove enough CO2 from the atmosphere to make a difference. Even
