It is widely believed in the scientific community that human activities are driving global climate change, but a video shared on Instagram on November 13th shows what are known to be confusing claims. people are not wrong.
In the video, Piers Corbyn, an astrophysicist, said the heat waves are caused by “some circulation patterns” from the sun’s activity and the phases of the moon.
“These things are marked by the work of the sun and the moon,” Corbyn said in the video, an excerpt from his 2010 appearance on Russia Today, a news channel of the Russian government. “It has nothing to do with people.”
He accused people who say human activity contributes to climate change “just trying to make money.”
The Instagram post’s caption reads, “this guy gets it, pay attention,” along with hashtags like #globalwarminghoax and #climatechangehoax.
The Instagram post was marked as part of Instagram’s efforts to combat false and misleading information on its News Feed. (Read more about our partnership with Meta, which owns Facebook and Instagram.)
Climate scientists say the sun and moon influence Earth’s climate, but not enough to contribute to the dramatic climate changes of the past decades.
PolitiFact has rated the news as undermining the human role in climate change.
NASA and the Environmental Protection Agency concluded that humans began to influence Earth’s climate during the Industrial Revolution, when the construction and burning of fossil fuels led to the release of greenhouse gases such as carbon dioxide in the atmosphere.
Nearly 200 scientific organizations have concluded that human activities are driving climate change.
Corbyn, the younger brother of British politician Jeremy Corbyn, earned a doctorate in astrophysics in 1981. He launched a weather forecasting company in 1995 called WeatherAction, which he has used to on climate change as a “promotion” and promoting anti-vaccination conspiracy theories about the COVID-19 pandemic.
In 2021 he compared the release of the COVID-19 vaccine in the United Kingdom to the Holocaust.
The influence of the sun and moon on the sky
If the sun is responsible for climate change, it has been more than measured solar radiation since the late 1970s when scientists began to see a rapid increase in global temperature, according to the National Oceanic and Atmospheric Administration.
However, according to NASA, scientists have not seen a significant increase in solar radiation since 1978, when they began using satellites to measure the amount of energy of the sun will be received by the earth. A 2008 study conducted in the United Kingdom found that there has been a 20-year decrease in solar activity, but no decrease in global temperatures.
If the sun plays a large role in climate change, it will affect the warming of every layer of the Earth’s atmosphere. NOAA and NASA report that it is warming the lower atmosphere but cooling the upper atmosphere, consistent with climate change due to the creation of greenhouse gases in the lower atmosphere of the earth, which holds the heat.
That’s not to say that the sun doesn’t affect the country’s climate, but it has less of an effect on Corbyn’s claims.
The video refers to “some circulation patterns” related to the flow of air around the Earth through the circulation. Due to the intense heat of the sun near the equator, the warm air from that area flows to the north and south.
As the air moves through the poles, it cools and returns to the equator to warm again, repeating the pattern, according to the University of Atmospheric Research. This wind movement influences daily weather and local weather, but not global change.
Researchers at the University of Reading in the United Kingdom have studied the effect of the moon on climate change. The study, which has not yet been peer-reviewed, found that shifts in the moon’s orbit could increase or decrease the Earth’s climate by up to 0.04 degrees Celsius based on a change in the light.
Ed Hawkins, the lead author of the study, told New Scientist, a British magazine, that the moon has a “small effect” on the climate and does not explain the observed long-term trends. and global warming.
Our decision
The Instagram post says that climate change is “supposed to be caused by the sun and moon” and “has nothing to do with humans.”
Scientists have discovered that the sun and moon affect the Earth’s climate, but their influence is small and does not take into account the rapid changes in the Earth’s climate over decades. it has passed.
Many scientists and scientific organizations agree that human activity will have a significant impact on climate change.
We conclude this claim to be false.
