Geoengineering by Gernot Wagner review – a stark warning

Spraying aerosols into the atmosphere may be fraught with risk, but to dismiss it out of hand is irresponsible, a climate scientist argues

www.theguardian.com

Gernot Wagner has spent a large part of his life thinking about solar geoengineering, and even he thinks it is “nuts”, as he says in the first line of his book. Geoengineering is usually defined as large-scale interventions in our climate. Here, although Wagner refers briefly to carbon removal and natural climate solutions such as tree-planting, he is mainly concerned with solar geoengineering (also called solar radiation management), where aerosols would be deployed into the stratosphere to reflect sunlight back into space and reduce the amount of heat coming in. The comparison he returns to most often is that of the ash from a volcanic explosion.

Solar geoengineering could also – this is the highly imperfect part – have a long list of downsides. They include its possible impact on rainfall, leading to drought and thus potentially millions of deaths; ozone depletion; continued ocean acidification; impact on plants and whitening of skies. Then there is the governance issue: who would be in charge of the programme? What would be the best way to run such a thing?

Very interesting video by Elon on the matter of Climate Change. I strongly recommend to everybody to listen to this video by Elon who manages to deal with this delicate matter in a very unbiased way so that anybody I think can say that he speaks having in mind any particular interest but only in the Interest of mankind.

Actually it's not a matter of a game in my opinion.
CO2 produced by ICE cars is responsible of temperature increasing in the world. As temperature increases ice at the North pole melts. As ice melts the salt concentration in the sea decreases. As the salt concentration in the sea decreases the current of the Channel decreases. When the current of the Channel will stop the North side of the Earth will get frozen.
Have you seen the film "The day after tomorrow"?
This film shows what will happen when the current of the Channel will stop. So driving pure electric is useful to save the Earth.

Do you still want to game?

I would be thankful to all people disagreeing with my post which originated this thread if they also reported the scientific reasons for their disagreement.

Apple and Disney among companies backing groups against US climate bill

Some of America’s most prominent companies, including Apple, Amazon, Microsoft and Disney, are backing business groups that are fighting landmark climate legislation, despite their own promises to combat the climate crisis, a new analysis has found. A clutch of corporate lobby groups and organizations have mobilized to oppose the proposed $3.5tn budget bill put forward by Democrats, which contains unprecedented measures to drive down planet-heating gases. The reconciliation bill has been called the “the most significant climate action in our country’s history” by Chuck Schumer, the Democratic leader in the US Senate.

We need an angry button because this *sugar* makes me irate! At the same time our little ones are growing up watching Disney, now Disney+, the company is preventing any progress towards making their future planet a better place to live.

What’s the Least Bad Way to Cool the Planet? Opinion | What’s the Least Bad Way to Cool the Planet?

To cool the planet in this century, humans must either remove carbon from the air or use solar geoengineering, a temporary measure that may reduce peak temperatures, extreme storms and other climatic changes. Humans might make the planet Earth more reflective by adding tiny sulfuric acid droplets to the stratosphere from aircraft, whitening low-level clouds over the ocean by spraying sea salt into the air or by other interventions.

Yes, this is what it comes down to: carbon removal or solar geoengineering or both. At least one of them is required to cool the planet this century. There are no other options.

Think that carbon removal is much better than solar geoengineering. I read that there are many risks for the Earth with solar geoengineering.
To this concern I wish to report this article explaining the solar geoengineering technique and the risks involved in such a technique.

Fossil fuel industry gets subsidies of $11m a minute, IMF finds

The IMF found the production and burning of coal, oil and gas was subsidised by $5.9tn in 2020, with not a single country pricing all its fuels sufficiently to reflect their full supply and environmental costs. Experts said the subsidies were “adding fuel to the fire” of the climate crisis, at a time when rapid reductions in carbon emissions were urgently needed. Explicit subsidies that cut fuel prices accounted for 8% of the total and tax breaks another 6%. The biggest factors were failing to make polluters pay for the deaths and poor health caused by air pollution (42%) and for the heatwaves and other impacts of global heating (29%).

How solar panels can improve farming

Trashing the planet and hiding the money isn’t a perversion of capitalism. It is capitalism | George Monbiot

England, in 1847, was at the centre of an empire whose capitalist endeavours had long eclipsed those of the Portuguese. For three centuries, it had systematically looted other nations: seizing people from Africa and forcing them to work in the Caribbean and North America, draining astonishing wealth from India, and extracting the materials it needed to power its Industrial Revolution through an indentured labour system often scarcely distinguishable from outright slavery. When Jane Eyre was published, Britain had recently concluded its first opium war against China.

Financing this system of world theft required new banking networks. These laid the foundations for the offshore financial system whose gruesome realities were again exposed this week. “English funds” were simply a destination for money made by the world-consuming colonial economy called capitalism.

The fire front still rages across the world, burning through people and ecologies. Though the money that ignites it may be hidden, you can see it incinerating every territory that still possesses unexploited natural wealth: the Amazon, west Africa, West Papua. As capital runs out of planet to burn, it turns its attention to the deep ocean floor and starts speculating about shifting into space. The local ecological disasters that began in Madeira are coalescing into a global one. We are recruited as both consumers and consumed, burning through our life support systems on behalf of oligarchs who keep their money and morality offshore.

How solar panels can improve farming

I do not know for sure, of course. I think this would be a nonstarter here in the Valley. The acreage per farm is huge--very few 20 and 40 ac parcels. Most are quarter or half sections of almonds, stone fruit, pistachios, grapes, and citrus. Grapes might work OK, but I seriously doubt that other permanent crops would realize a sensible balance between electricity and yield. Row crops would include processing tomatoes, melons, a little cotton, and the occasional cool season plantings of lettuce, broccoli, and perhaps garbs and baby limas.

It might be more receptive near Watsonville and the Salinas Valley with all the strawberries, artichokes, and leafy vegetables grown thereabouts throughout the year. Perhaps even the Delta and the asparagus fields there would benefit.

Interesting video, and likely a workable situation for smaller farms in cooler areas.

Which Climate Threats Are Most Worrisome? U.S. Agencies Made a List. Which Climate Threats Are Most Worrisome? U.S. Agencies Made a List.
Less food. More traffic accidents. Extreme weather hitting nuclear waste sites. Migrants rushing toward the United States, fleeing even worse calamity in their own countries. Those scenarios, once the stuff of dystopian fiction, are now driving American policymaking. Under orders from President Biden, top officials at every government agency have spent months considering the top climate threats their agencies face, and how to cope with them.

Why California’s enormous oil spill won’t be its last

While the US Coast Guard believes a ship’s anchor may have damaged the pipeline months ago, California’s ageing oil infrastructure will also bear increasing scrutiny. Experts say that the devastating spill is unlikely to be the last, especially in a rapidly changing industry where equipment is primed to suffer from underinvestment and lack of attention.

Kammen says that some companies may take this moment of change to invest well, harden their lines, and use the pipes to transport a greener fuel, such as hydrogen. But others are likely to phase down and underinvest in the upkeep of the infrastructure. “High-level decisions made by companies have a direct feed down to management,” he says. “Accidents and spills are likely to happen as the amount of vigilance goes down.”

Indigenous protesters urge Biden to stop approving fossil fuel projects

Outside the White House, the words “Expect Us” were spray-painted on the base of a statue of Andrew Jackson, the seventh US president who is infamous for, among other things, leading the violent and lethal repression of Native American peoples in a displacement known as the Trail of Tears. “Expect Us” is part of the phrase “Respect Us, or Expect Us,” which many Indigenous women have been using while demonstrating against the Canadian oil company Enbridge’s $9bn upgrade of an oil pipeline designed to carry oil from Alberta, Canada, to Wisconsin.
