The feasibility of getting to Net-Zero carbon dioxide

Here is an optimistic article on achieving net-zero carbon emissions:

Getting to Net Zero – and Even Net Negative – is Surprisingly Feasible, and Affordable – New analysis provides detailed blueprint for the U.S. to become carbon neutral by 2050

“Reaching zero net emissions of carbon dioxide from energy and industry by 2050 can be accomplished by rebuilding U.S. energy infrastructure to run primarily on renewable energy, at a net cost of about $1 per person per day, according to new research published by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), the University of San Francisco (USF), and the consulting firm Evolved Energy Research. The researchers created a detailed model of the entire U.S. energy and industrial system to produce the first detailed, peer-reviewed study of how to achieve carbon-neutrality by 2050. According to the Intergovernmental Panel on Climate Change (IPCC), the world must reach zero net CO2 emissions by mid-century in order to limit global warming to 1.5 degrees Celsius and avoid the most dangerous impacts of climate change.”

Refreezing the arctic ice cap seems riduclous and impossible, but it is being suggested before weather patterns go crazy

This article states the problem…

We need to start refreezing the Arctic Ocean as soon as possible to save our megacities

“Rising carbon levels have already led to a 4C rise in Arctic temperatures, which has led to a 75 per cent loss of Arctic summer-ice volume. This has led, in turn, to the dark waters of the Arctic Ocean being exposed, which absorb heat from the sun. If they were covered with white ice, this would reflect it and thus keep the earth cooler. But the warmer Arctic waters are now melting the adjacent enormous ice-cap on Greenland at a rate seven times faster than in the 1990s, which in turn is raising global sea-levels faster than predicted.”

The ultimate solution, as mentioned in other posts on this blog, is to stop burning fossil fuels and simultaneously start extracting carbon dioxide from the atmosphere.

But the situation is so dire in the Arctic that at least one scientist thinks humans should be artificially creating ice in the Arctic to create more reflective area. Here’s how:

“We now have to literally refreeze the Arctic Ocean, otherwise the heat from its open seas will continue to accelerate the melting of the Greenland ice-cap – which has enough water stored in it to raise the world’s oceans by seven metres. Research at Edinburgh University has proposed that if the clouds over the Arctic in summer are sprayed with sea-water, the salt in it would make the clouds whiter. This would reflect the sun’s heat and the ocean waters below them would start to refreeze.”

Can the nations of the world get their act together enough to implement something like this? This is the many-trillion dollar question, because once sea levels start rising to that degree, we will lose many important cities to flooding.

Many parts of the world will become uninhabitable to humans and animals as the planet heats up

Planet Earth is growing warmer, and as it does we will see parts of the planet become uninhabitable due to heat and humidity. The southeastern United States is vulnerable to this – it will be impossible to go outside without an air conditioned vehicle or suit:

Climate Change Will Make Parts of the U.S. Uninhabitable. Americans Are Still Moving There.

From the article:

The data shows that the warming climate will alter everything from how we grow food to where people can plausibly live. Ultimately, millions of people will be displaced by flooding, fires and scorching heat, a resorting of the map not seen since the Dust Bowl of the 1930s. Now as then, the biggest question will be who escapes and who is left behind.

It’s crazy to think that it will come to this – that humans will choose to destroy the planet instead of taking action to stop the burning of fossil fuels. Nonetheless, this is the path humanity is following right now, and it will have gigantic economic and social costs for all human beings unless we as a species change course. See the Global Warming chapter for details. And this video paints a dire picture:

Extreme Heat Could Make One Third of Planet Uninhabitable

Scientists Increasingly Shocked by the Loss of Sea Ice in the Arctic

Many articles over the last several weeks have been pointing out the gigantic warning that humanity is receiving from the massive loss of ice in the Arctic. It is an undeniable sign of the planet’s warming, and it is only going to get worse unless humanity takes action:

Drone footage shows extent of Arctic ice loss

“The Arctic is warming twice as fast as the rest of the world,” Dr. Enric Sala, executive producer and National Geographic’s Explorer-in-Residence said in a panel discussion following the film’s premiere on Oct. 7. “The Inuit are really the human face of global warming, and all these activities that produce all this carbon pollution are not in the Arctic region, they are mostly in a world where we are or farther south, but they are suffering the consequences.”

Climate scientists and activists responded with alarm Thursday to reporting that this is the latest date in recorded history that “the main nursery of Arctic sea ice in Siberia has yet to start freezing,” another example of the present-day consequences of human-caused global heating. According to the Guardian, “The delayed annual freeze in the Laptev Sea has been caused by freakishly protracted warmth in northern Russia and the intrusion of Atlantic waters, say climate scientists who warn of possible knock-on effects across the polar region.”

In August, Adrienne White – an ice analyst at the Canadian Ice Service who monitors the Canadian Arctic for changes in sea ice – was reviewing satellite imagery when she spotted something remarkable. The enormous Milne ice shelf, which was the last intact ice shelf in Canada and which White had studied closely before as a PhD student, was dissolving. A huge chunk larger than Manhattan, roughly 43% of the shelf, broke off in one piece. And as it collapsed into the ocean, it took with it much of the equipment her former colleagues had left there.

What a ‘sobering’ report on Arctic ice loss means for global sea levels

Will humanity do anything to solve this crisis? Will it undertake the immense global effort necessary to reverse all of the damage that has been done?

How green sand could capture billions of tons of carbon dioxide

How green sand could capture billions of tons of carbon dioxide

Later this year, Project Vesta plans to spread a green volcanic mineral known as olivine, ground down to the size of sand particles, across one of the beaches. The waves will further break down the highly reactive material, accelerating a series of chemical reactions that pull the greenhouse gas out of the air and lock it up in the shells and skeletons of mollusks and corals.

Megaprojects to reverse climate change

This video covers technologies to control the temperature of the planet, either by reducing greenhouse gases or by diminishing the amount of sunlight hitting the planet:

4 Megaprojects That Could Reverse Climate Change | Answers With Joe
  • Biomass energy with carbon capture storage (BECCS)
  • Direct Air Capture
  • Carbon capture and sequestration
  • Artificial volcanoes
  • Stratospheric aerosol injection
  • Satellites in orbit

It is time to start capturing carbon out of the atmosphere

This article makes the case for pulling carbon dioxide back out of the atmosphere starting now:

There Are So Many Ways Of Capturing Carbon Dioxide: We Must Start Using Them Now

The article offers several options:

The article does not think highly of the value of direct air capture, but there is a lot to like about this technology:
