Concern grows over rich nations controlling sunlight

Say hello to an umbrella term for outlandish climate intervention schemes, or maybe scams: SRM (solar radiation management).

Radical climate interventions — like blocking the sun’s rays — could alter the world’s weather patterns, potentially benefiting some regions of the world and harming others, says E&E News.

That possibility, climate scientists say, means any research on such methods must consider those risks and involve the countries that already bear the greatest impacts from a warming planet.

“If you’re actually talking about actively deploying technologies to alter the climate, then you need to engage all of us in the discussion,” said Andrea Hinwood, chief scientist at the United Nations Environment Programme in Nairobi, Kenya. “And that means those who are the most vulnerable to these effects need to be able to have a say.”

The push for inclusive research comes alongside growing interest — and debate — over solar radiation management, a little understood way to avoid catastrophic climate change by injecting sunlight-blocking particles into the stratosphere or changing the density of clouds.

Climate scientists are, by and large, wary of such intervention. While limiting the amount of sunlight that reaches the Earth could rapidly cool the planet, they say, such efforts wouldn’t address ocean acidification and other harms associated with burning fossil fuels, the primary cause of global warming.[Talkshop comment – so they say, offering no empirical evidence].

It’s also unclear how solar radiation management, or SRM, would affect global weather patterns, such as the monsoon rains that are crucial in some regions of the Global South. While it could ease climate impacts in one area of the world, SRM might reduce crop yields or threaten water supplies in another area.

The Global North is home to most of the experts and institutions that conduct research into climate change — and to the funding to deploy new climate technologies.

That threatens to exacerbate the growing divide between the wealthy countries that have contributed most of the emissions warming the planet and the poorer ones forced to bear the resulting impacts in the form of more extreme storms, heat, droughts and rising seas.

“If the Global South is not included, any geoengineering activity has the potential to tilt the balance of power towards nations that are already powerful,” Govindasamy Bala, a professor at the Indian Institute of Science and an author of the UNEP report, said in an email.

    Having spent billions – perhaps trillions – curbing sulphur dioxide emissions to prevent the dreaded acid rain, now they’re wittering about pumping it back in again to prevent global warming.

    You couldn’t make it up!

    I don’t hear any discussion about lowered farm yields due to weaker insolation. Seems more like another plot to reduce the food supply and starve us.

    Not surprising, when they don’t understand the climate 🙄

    But there’s a plan…

    Old bomber will sniff the sky for geoengineering aerosols

    The United States hopes the mission will provide more data to help it and other members of the United Nations engage in an informed debate about solar geoengineering.

    “We have to know more about how aerosols act in the climate system to better understand the costs and benefits of climate intervention,” said Karen Rosenlof, a senior scientist at NOAA’s Chemical Sciences Laboratory, in a statement released last week.

    “We are already seeing detrimental impacts on the biosphere and the economy due to climate change, and we should expect that they’re only going to get worse.”
