Efforts to Curtail World Temps Will Almost Surely Fail

Last December, officials representing more than 190 countries met in Paris to participate in the United Nations Climate Change Conference.  The historic outcome from that conference was the "Paris Agreement" in which each country agreed to reduce greenhouse gas emissions in order to limit global warming to less than 2 degrees Celsius (3.6 degrees Fahrenheit) above temperatures seen near the start of the Industrial Revolution in the 1850s.  Such a level was considered acceptable, or "safe," by all participating countries, but the goal is unrealistic and almost impossible to achieve, according to a new study by two Texas A&M University at Galveston researchers.

Glenn Jones (professor of marine sciences) and Kevin Warner (Ph.D. candidate in marine biology), have had their paper published in the international journal Energy Policy.

The Texas A&M researchers modeled the projected growth in global population and per capita energy consumption, as well as the size of known reserves of oil, coal and natural gas, and greenhouse gas emissions to determine just how difficult it will be to achieve the less-than-2 degree Celsius warming goal.

"It would require rates of change in our energy infrastructure and energy mix that have never happened in world history and that are extremely unlikely to be achieved," explains Jones.

The Paris Agreement's overall goal is to replace fossil fuels, which emit huge amounts of carbon dioxide into the atmosphere which in turn leads to higher temperatures, with renewable energy sources such as solar and wind power and biofuels.

"Just considering wind power, we found that it would take an annual installation of 485,000 5-megawatt wind turbines by 2028.  The equivalent of about 13,000 were installed in 2015.  That's a 37-fold increase in the annual installation rate in only 13 years to achieve just the wind power goal," adds Jones.

Similar expansion rates are needed for other renewable energy sources.
