Tectonics in the tropics trigger Earth’s ice ages, says study

Glacier in Patagonia

The latest Ice Ages theory rolls off the production line. This one relies on ‘pulling enough carbon dioxide out of the atmosphere’, so we can see how they’re thinking. A possible problem there is that historical data from ice cores usually show carbon dioxide changes following temperature changes by a few hundred years, which seems to contradict the findings here. It’s the old chicken and egg conundrum – effects can’t precede causes. An important part of the carbon cycle is ocean outgassing of CO2 (response to warming) and absorption (response to cooling).

Over the last 540 million years, the Earth has weathered three major ice ages—periods during which global temperatures plummeted, producing extensive ice sheets and glaciers that have stretched beyond the polar caps.

Now scientists at MIT, the University of California at Santa Barbara, and the University of California at Berkeley have identified the likely trigger for these ice ages, reports Phys.org.

In a study published in Science, the team reports that each of the last three major ice ages were preceded by tropical “arc-continent collisions”—tectonic pileups that occurred near the Earth’s equator, in which oceanic plates rode up over continental plates, exposing tens of thousands of kilometers of oceanic rock to a tropical environment.

The scientists say that the heat and humidity of the tropics likely triggered a chemical reaction between the rocks and the atmosphere.

Specifically, the rocks’ calcium and magnesium reacted with atmospheric carbon dioxide, pulling the gas out of the atmosphere and permanently sequestering it in the form of carbonates such as limestone.

Over time, the researchers say, this weathering process, occurring over millions of square kilometers, could pull enough carbon dioxide out of the atmosphere to cool temperatures globally and ultimately set off an ice age.

“We think that arc-continent collisions at low latitudes are the trigger for global cooling,” says Oliver Jagoutz, an associate professor in MIT’s Department of Earth, Atmospheric, and Planetary Sciences. “This could occur over 1-5 million square kilometers, which sounds like a lot. But in reality, it’s a very thin strip of Earth, sitting in the right location, that can change the global climate.”

Jagoutz’ co-authors are Francis Macdonald and Lorraine Lisiecki of UC Santa Barbara, and Nicholas Swanson-Hysell and Yuem Park of UC Berkeley.

A tropical trigger

When an oceanic plate pushes up against a continental plate, the collision typically creates a mountain range of newly exposed rock. The fault zone along which the oceanic and continental plates collide is called a “suture.” Today, certain mountain ranges such as the Himalayas contain sutures that have migrated from their original collision points, as continents have shifted over millenia.

In 2016, Jagoutz and his colleagues retraced the movements of two sutures that today make up the Himalayas. They found that both sutures stemmed from the same tectonic migration. Eighty million years ago, as the supercontinent known as Gondwana moved north, part of the landmass was crushed against Eurasia, exposing a long line of oceanic rock and creating the first suture; 50 million years ago, another collision between the supercontinents created a second suture.

The team found that both collisions occurred in tropical zones near the equator, and both preceded global atmospheric cooling events by several million years—which is nearly instantaneous on a geologic timescale.

After looking into the rates at which exposed oceanic rock, also known as ophiolites, could react with carbon dioxide in the tropics, the researchers concluded that, given their location and magnitude, both sutures could have indeed sequestered enough carbon dioxide to cool the atmosphere and trigger both ice ages.

Interestingly, they found that this process was likely responsible for ending both ice ages as well. Over millions of years, the oceanic rock that was available to react with the atmosphere eventually eroded away, replaced with new rock that took up far less carbon dioxide.

“We showed that this process can start and end glaciation,” Jagoutz says. “Then we wondered, how often does that work? If our hypothesis is correct, we should find that for every time there’s a cooling event, there are a lot of sutures in the tropics.”

The Next Wave of Extremists Will Be Green

Militant environmentalism is coming. And we aren’t ready for it.

If military strategists are always fighting the last war, the same is true of those who work on countering radicalization. In 2001, Western intelligence services, mostly focused on localized terrorist groups like the Irish Republican Army and ETA, were stunned by al Qaeda. Come 2011, they were then blindsided by Anders Behring Breivik and the growth in far-right extremism. By the mid-2010s, the Islamist threat had evolved into the Islamic State — and they were slow to spot that, too.

Today, we are about to make the same mistake. We will not easily forgive ourselves if our attention is exclusively occupied by the Islamic State or the far-right when the coming wave of environmental radicalization hits.

There’s nothing new about radical environmentalism. In 2001, the Earth Liberation Front — a militant, violent environmentalist group — was described by the FBI as one of the top domestic terrorist threats. Academics have estimated that “REAR” (Radical Environmentalist and Animal Rights) cells can be found in at least 25 countries and were responsible for more than 1,000 criminal acts between 1970 and 2007 in the United States alone — mostly vandalism and attacks on animal testing facilities. Over the last 30 years, there have been periodic fears about new waves of “eco-terrorism,” which have never quite materialized.

But, until recently, radical environmentalism had been a victim of its own success. Green ideas went mainstream years ago. Most major political parties in Western democracies (Donald Trump and the Republican Party notwithstanding) now accept the facts of climate change and have promised to respond. Environmentalism has also become part of the broader anti-capitalism movement, which is — mostly — characterized by a commitment to nonviolence and bottom-up change. As a result, climate activism that crosses from peaceful protests, like marching in the streets, to civil disobedience — shutting down mines or monkey-wrenching machinery — remains stubbornly small. There are no exact figures, but people on the inside have told me that, in the U.K. at least, it’s just a few hundred hardcore activists, and a few thousand in the United States.

There are clues, however, that this may be about to change. The necessary conditions for the radicalization of climate activism are all in place. Some groups are already showing signs of making the transition. And when they do, we may be ill-equipped for handling these new green hard-liners.

Climate Control: Brainwashing In Schools

GWPF report finds eco-activism is being given a free rein in many UK schools. In every case of concern, the slant is on scares, on raising fears, followed by the promotion of detailed guidance on how pupils should live, as well as on what they should think.

Executive summary

We have found examples of serious errors, misleading claims, and bias through inadequate treatment of climate issues in school teaching materials. These include many widely-used textbooks, teaching-support resources, and pupil projects.

The National Curriculum has recently been reviewed by the government, but the proposed changes seem unlikely to prevent such practices.

Surveys show that many children are upset and frightened by what they are told is happening to the climate.

Teachers and administrators have a fairly free hand to choose textbooks, other materials, visiting speakers and school trips for pupils provided they fit in with curricular goals. This raises the risk that some may select alarming and politically loaded sources in order to win children over to the ‘environmental cause’.

This ‘cause’ is often presented through the notion of ‘sustainability’, a poorlydefined catchword covering political and personal actions for which fundamental criticism is rarely entertained.

Many campaigning NGOs and other organisations with vested interests such as energy companies proffer teaching materials and other resources for use in schools. Some of it is presumably being used.

There are clear grounds for very serious concern. We therefore call upon the Secretary of State for Education and his counterparts in Scotland, Wales and Northern Ireland to undertake urgent inquiries into climate change education in our schools. Only a systematic evaluation of what is going on can determine the extent of the indoctrination as well as the emotional and educational harm to pupils that is undoubtedly resulting.
