‘Geoengineers’ Could Hijack the Earth’s Weather Systems and Trump Approves


geoengineering

Harvard engineers who launched the world’s biggest solar geoengineering research program may get a dangerous boost from Donald Trump, environmental organizations are warning.

CONTROVERSIAL

Under the Trump administration, enthusiasm appears to be growing for the controversial technology of solar geo-engineering, which aims to spray sulphate particles into the atmosphere to reflect the sun’s radiation back to space and decrease the temperature of Earth.

TESTING

Sometime in 2018, Harvard engineers David Keith and Frank Keutsch hope to test spraying from a high-altitude balloon over Arizona, in order to assess the risks and benefits of deployment on a larger scale.

 CANCELED IN 2012

Keith cancelled a similar planned experiment in New Mexico in 2012, but announced he was ready for field testing at a geoengineering forum in Washington on Friday.

“The context for discussing solar geoengineering research has changed substantially since we planned and funded this forum nearly one year ago,” a forum briefing paper noted.

GEOENGINEERING

While geoengineering received little favour under Obama, high-level officials within the Trump administration have been long-time advocates for planetary-scale manipulation of Earth systems.

FEDERAL SUPPORT

David Schnare, an architect of Trump’s Environmental Protection Agency transition, has lobbied the US government and testified to Senate in favour of federal support for geoengineering.

SPRAY FOR CENTURY

He has called for a multi-phase plan to fund research and conduct real-world testing within 18 months, deploy massive stratospheric spraying three years after, and continue spraying for a century, a duration geoengineers believe would be necessary to dial back the planet’s temperature.

CURTAIL RAIN IN SOME AREAS

Geoengineers argue that such methods would be an inexpensive way to reduce global warming, but scientists have warned it could have catastrophic consequences for the Earth’s weather systems. Scientific modelling has shown that stratospheric spraying could drastically curtail rainfall throughout Asia, Africa and South America, causing severe droughts and threatening food supply for billions of people.

“Clearly parts of the Trump administration are very willing to open the door to reckless schemes like David Keith’s, and may well have quietly given the nod to open-air experiments,” said Silvia Riberio, with technology watchdog ETC Group. “Worryingly, geoengineering may emerge as this administration’s preferred approach to global warming. In their view, building a big beautiful wall of sulphate in the sky could be a perfect excuse to allow uncontrolled fossil fuel extraction. We need to be focussing on radical emissions cuts, not dangerous and unjust technofixes.”

REPORT

A White House report on climate change research submitted to Congress in January called for the first time ever for research into geoengineering.

GOP ADVOCATING

Within Republican ranks, former House speaker and Trump confidant Newt Gingrich was one of the first to start publicly advocating for geoengineering.

“Geoengineering holds forth the promise of addressing global warming concerns for just a few billion dollars a year,” he said in 2008, before helping launch a geoengineering unit while he ran the right-wing think tank American Economic Enterprise. “We would have an option to address global warming by rewarding scientific innovation. Bring on American ingenuity. Stop the green pig.”

REX TILLERSON

US Secretary of State Rex Tillerson has also appeared to support geoengineering, describing climate change as an “engineering problem.” ExxonMobil’s funding of the climate denial industry is under investigation by attorney generals in the United States, but it’s less well known that ExxonMobil scientists under Tillerson’s reign as CEO were leading developers of geo-engineering technologies like carbon dioxide removal.

MEETING EXXONMOBIL

Asked about solutions to climate change at an ExxonMobil shareholder meeting in 2015, Tillerson said that a “plan B has always been grounded in our beliefs around the continued evolution of technology and engineered solutions.”

“We are not unalterably committed to doing the experiment,” said David Keith on Friday. “We’re headed down the road of doing that, but depending on what an advisory committee says and what we learn technically we’re certainly willing to stop. Our long term goal is to build a sustainable effort in solar geoengineering research that allows us to say more about ways it might actually provide public benefit.”

CRITICS

Critics point out that those who don’t believe in human-induced climate change may still support geoengineering, which can be presented as a method to deal with the consequences of a warming planet without stopping the burning of fossil fuels.

UNITED NATIONS CONVENTION

The Harvard experiment may fly in the face of a moratorium on geoengineering adopted in 2010 by the United Nations Convention on Biological Diversity, which was reaffirmed in December in Mexico. The United States is one of the few countries to not ratify the UN convention, creating a potential loophole for experiments.

SITE FOR EXPERIMENT

The experiment’s site in Tucson, Arizona may also invoke issues of jurisdictional controversy with Mexico – stratospheric winds can blow up to 200 miles per hour, and the border is only 75 miles away.

CLOUD WHITENING

Other geoengineering experiments like cloud whitening may go ahead in the United States, as well as experiments supported by the governments of China and Russia, though both are signatories to the UN moratorium.
