Bill Gates Claims 'Discovered' the 14-Year Formula on Climate Change
Bill Gates has just released a climate science equation that describes how the world can reduce carbon dioxide emissions "to zero".
This is broadcast online February 22, in the form of the 2016 edition of the annual letter Bill Gates and his wife, Melinda, publish.
The problem is, these equations are not entirely new. This is widely recognized in the climate science community as Rich's identity, and was reviewed in the scientific literature in 2002 in the journal Proceedings of the National Academy of Sciences.
But instead of roasting Gates about the formula's origins, climate scientists love him talking about it, said Michael Mann, a leading professor of atmospheric science at Pennsylvania State University.
My guess is, he's seen this somewhere in the past, and kind of forgot where it came from. And thought that maybe he did it. I will give him the benefit of the doubt, "said Mann, quoted by the page LiveScience, Sunday (31/1/2021).
The origin of the Gates equation may remain a mystery for the time being, the Bill & Melinda Gates Foundation did not reply to Live Science's requests for comment.
According to Mann, no matter where the equation comes from, it can help scientists keep tabs on carbon dioxide emissions.
This is a way of breaking down our carbon emissions into a number of factors, each of which we can try to focus on separately, "explains Mann.
However, none of the factors are independent of one another, so they cannot be looked at in isolation, says Mann.
Here is an excerpt from Gates' annual letter explaining the variables:
"Here's what I got: P * S * E * C = CO2," Gates wrote. "That may seem complicated. It's not.
"On the right you have the total amount of carbon dioxide (CO2) we put into the atmosphere. This is what we need to get to zero. This is based on four factors on the left side of the equation: World population (P) times services (S) used by each person; the energy (E) needed to provide each of these services; and, finally, the carbon dioxide (C) that that energy produces. "
Both sides of the equation must hit zero, Gates said. So, one of the variables on the left must equal zero for the world to reach its goal of zero emissions.
The first variable is population. The world supports about 7 billion people now, a figure projected to reach at least 9 billion by 2050.
The population will only continue to grow, or as Gates said in his letter, "it cannot be zero."
Services, such as food, clothing, cars and heating, are also developing, "so (S) also cannot be zero," he said.
"However, the energy required for each service is getting less and less thanks to advances in technology, such as LED light bulbs," said Gates.
He added that developing technologies, including solar and wind power, reduce carbon emissions.
"In short, we need an energy miracle to achieve zero carbon dioxide emissions. But the world is far from reaching zero for both energy and carbon emissions," he said.
Mann said he strongly disagreed.
He is doing injustice to the very dramatic breakthroughs made by renewable energy and energy efficiency, "said Mann, although he added that some of the developments were quite recent.
For example, scientists at Stanford University in California have peer reviewed, published research (the most respected type of research) that has a very credible outline of how we can achieve 100 percent non-carbon energy generation by 2050.
Different regions will require different strategies, but a mix of renewable energies - such as wind, solar and geothermal - can help reduce energy emissions substantially, "concluded Mann.
Study: Climate Change Risks to Increase Malnutrition in Children
The temperature rise caused by climate change is contributing to low food quality. This has resulted in the problem of malnutrition or malnutrition in children in various countries.
According to researchers from the University of Vermont, climate change is just as bad as other causes of malnutrition, such as low quality diets, poverty, poor sanitation, and so on.
"Of course, future climate change has been expected to affect malnutrition, but it surprises us that higher temperatures are already showing an impact," said study co-author Meredith Niles as quoted by Medicinenet. Niles is an assistant professor of nutrition and food science.
Launching Medicinenet, researchers assessed the diversity of food among 107,000 children aged 5 years and under in 19 countries in Asia, Africa and South America. They used three decades of temperature, rainfall, socioeconomic, ecological and geographic data.
