Posts mislead about global warming impact of microwave frequencies from 5G cell towers

Several posts shared hundreds of times around the world claim that microwave frequencies emitted by 5G cell towers and radar stations contribute significantly to global warming. However, experts told AFP that while the infrastructure needed to support 5G networks may marginally contribute to global warming, there is no evidence that microwave frequencies from 5G cell towers contribute to climate change. According to the United Nations, fossil fuels are by far the biggest contributor to global climate change, accounting for more than 75% of global greenhouse gas emissions.
“You don’t cover the Earth in cell towers and radar stations that all emit constant microwave frequencies at an ever-increasing level if you’re concerned about global warming…” reads the text in a shared image on Facebook here July 25, 2022.
It was shared in a Facebook group called “We say NO to 5G in Australia”, which has over 19,000 followers.
The image shows the Earth inside a microwave whose cell towers and radar stations protrude from the top.
The hashtags “#EMFRadiation #WeaponizedWiFi #AMicrowavedPlanet #Stop5G #SinkTheSmartGrid” are also included at the bottom of the image.
However, the claim is misleading, experts say.
Claim on global warming
Doctor Sarah Loughran, “There is no evidence that radio waves, microwave frequencies or 5G technologies are linked to or contribute to global warming in any way”.
She went on to say that it is also false to state that “cell towers are emitting constant microwave frequencies at an increasing level.”
“Cell towers use radio waves to connect mobile devices and emissions must meet exposure limits set out in the Australian safety standard,” she said.
Fossil fuels – coal, oil and gas – remain the biggest contributor to global climate change, accounting for more than 75% of global greenhouse gas emissions, according to the The United Nations.
Other contributors include electricity generation, good manufacturing, forest destruction, transportation use, food production, building energy use and overconsumption, according to the UN.
On the other hand, the telecommunications industry contributes about 1.4%, as pointed out by experts in this report from the telecommunications company Ericsson, based in Stockholm.
Doctor Diep NguyenA senior lecturer at the University of Technology Sydney, told AFP that linking 5G technology to global warming is “too extreme” because every action that requires energy can contribute to climate change.
He said 5G technology is more energy efficient than 4G or 3G networks.
“5G consumes more power than 4G in terms of totality, but for power per unit of data, 5G is much more power efficient than 4G and others,” he said.
Not harmful to humans
Experts have previously told AFP there is no evidence 5G is harmful to the human body and dismissed false claims that it created the new coronavirus.
“There are no adverse health effects caused by exposure to 5G,” Rodney Croftprofessor at the University of Wollongong, told AFP.
“Radiation” refers to both ionizing and non-ionizing radiation, and although ionizing radiation (such as that from X-rays or nuclear reactions) can cause serious health effects such as cancer, radiation non-ionizing at 5G-related levels cannot cause any health effects,” he said.
According to the Australian Radiation and Nuclear Safety Agency (ARPANSE), cell phone towers in Australia emit low-level radio frequency (RF) electromagnetic energy (EME) that does not affect human health.
“No adverse health effects are expected from continued exposure to EME RF emitted from mobile phone base station antennas,” it says.
