Texas A&M-Galveston Study Shows
Efforts to Curtail World Temps Will Almost Surely Fail 

Galveston, Texas – 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 Accord” 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 their goals are 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, PhD candidate in Marine Biology have had their work published in the journal Energy Policy. The Texas A&M researchers modelled 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 how difficult it will be to achieve the less-than- 2 degree C 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 Accord’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 in 2028.  About 13,150 were installed in 2015. So that’s a 37-fold increase in the annual installation rate in only 13 years to achieve just the wind power goal,” Jones explains.  “Similar expansion rates are needed for solar and biofuels. An increase like that has never happened in the history of the world’s energy use.”

Recent statistics show that the month of February 2016 was the warmest February ever, while 2015 was also the warmest year since records have been kept.

Jones and Warner point out that every hour of every day:

·       3.7 million barrels of oil are extracted from the Earth

·       932,000 tons of coal are removed from Earth

·       395 million cubic meters of natural gas are removed from Earth

·       4.1 million tons of carbon dioxide are put into the Earth’s atmosphere

·       9,300 more people inhabit the Earth

“There will be about 11 billion people on Earth by 2100 (compared to 7.2 billion today),” Jones adds. “So the question becomes, how will they be fed and housed and what will be their energy source?  Currently 1.2 billion people in the world do not have access to electricity, and there are plans to try to get them on the grid.  The numbers you start dealing with become so large that they are difficult to comprehend.

“To even come close to achieving the goals of the Paris Accord, 50 percent of our energy will need to come from renewable sources by 2028, and today it is only 9 percent, including hydropower. For a world that wants to fight climate change, the numbers just don’t add up to do it.  If we don’t worry about global warming and the 2- degree Celsius goal, we can continue to burn known fossil fuel reserves, but even then we will have to achieve more than 50 percent renewable energy by 2054, but warming will exceed 2.5 to 3 degrees Celsius.

“A person living today uses about four times as much energy as a person did in 1900,” Jones adds. “By 2100, that figure goes up to five times. And 87 percent to 94 percent of all energy used will be from renewable sources regardless of whether we achieve and maintain the goals of the Paris Accord.”

The authors note history shows that rarely -- if ever – have government officials agreed on making such large-scale changes happen in such a short timeframe. “Our study does not present an either-or situation, rather the world will require a significant shift to renewable energy sources whether we care about global warming or whether we are more concerned with providing society’s energy needs,” Jones says. “Hopefully, our work will serve as a wake-up call.”
