Bill Gates donated hundreds of thousands of dollars to a project that sees the solution to climate change in the clouds

Many parts of the world have been under the pressure of extreme heat for the past week.

People living in Europe, America, and Turkey are going through challenging hours due to temperatures reaching up to 45 degrees Celsius. Dozens of individuals are seeking medical assistance at hospitals due to health issues caused by the extreme heat. There have been cases of deaths as well.

The increasing intensity of temperatures each year is primarily caused by human-induced climate change.

The rise in carbon emissions is thinning the ozone layer.

Scientists continue their work for the survival of the planet.

In June 1991, a rare natural event in the Philippines opened up new horizons for scientists.

The major eruption of Mount Pinatubo resulted in volcanic ash clouds reaching a distance of 40 kilometers in the atmosphere. The explosion was so powerful that the ash cloud blocked out the sun, causing a decrease in global temperatures by 0.6 degrees Celsius over the next two years. After two years, this effect came to an end.

The eruption of Mount Pinatubo resulted in the loss of nearly 900 lives, the destruction of hundreds of buildings and infrastructure, and caused significant damage to agricultural production in the region.

However, this disaster also inspired scientists working to prevent climate change. Over the next 30 years, researchers began exploring ways to mimic the sun-blocking effect of volcanoes and find methods to mitigate global warming. One of the most important criteria in these studies was to avoid creating a disruptive fluctuation effect.

Until a few years ago, when it came to efforts to prevent climate change, the primary focus was on limiting carbon emissions as quickly as possible. Geoengineering studies were relatively less prominent.

However, today, governments of the countries that produce the highest carbon emissions are seeking different avenues.

For example, the United States recently announced its 5-year plan for researching solar blocking techniques. A few days after this announcement, the European Union called for a global agreement that would prevent any country from “conducting experiments alone on our shared planet.”

he clouds formed after the eruption of Mount Pinatubo" is as follows.

Brighter clouds result in less warming.

One of the prominent techniques that has gained attention recently is marine cloud brightening. By injecting tiny water droplets into clouds over the ocean, the clouds are made brighter. Brighter clouds reflect more sunlight.

Kelly Wanser, the Executive Director of Silver Lining, a U.S.-based organization conducting research in the field of marine cloud brightening, stated, “There has been a significant shift in the past five years because scientists find short-term climate change, to put it mildly, quite alarming.”

Wanser further added, “The situation is worse than expected, and this means we need to take a closer look at alternatives.”

Is it possible to artificially recreate the effects of a volcano?

Another technique that has recently gained popularity is stratospheric aerosol injection. This process involves the spreading of aerosols in the form of sulfates into the atmosphere, either from aircraft or balloons, to mimic the effects created by volcanoes.

The Centre for Climate Repair at the University of Cambridge has declared one of its three priorities as restoring the Arctic to its ice-covered state as it was in the past. The institution advocates for conducting Marine Cloud Brightening by spraying seawater in the form of mist from hundreds of ships in the region.

David King, one of the founders of the center, stated in an interview with The Telegraph, “We need to buy time.” King, who has previously served as the Chief Scientific Adviser to the UK government, expressed his wish to start immediately, saying, “I wish we could start tomorrow.”

King highlighted that temperatures in the Arctic are rising four times faster than in the rest of the world, which could trigger “tipping points” leading to extreme sea-level rise and the release of methane through permafrost melting. Emphasizing that methane is a potent greenhouse gas, King added that in such a scenario, warming could reach up to 8 degrees Celsius. He stated, “Both rapidly rising sea levels and rapidly rising temperatures, these two factors as we know them today, would be the end of humanity.”

The cost is just a drop in the bucket compared to the devastation of global warming.

King mentioned that the cost of such a technology would be “a few billion dollars per year,” which he considered as “peanuts” compared to the trillions of dollars in damages caused by uncontrolled global warming.

One of the projects that King’s team is working on aims to restore fish populations in the oceans to the levels of 400 years ago. In this context, artificial whale feces are used as a type of fertilizer. This fertilizer, largely composed of volcanic ash, supports the growth of phytoplankton, a type of algae that plays a crucial role in the diet of fish.

Another function of the fertilizer is carbon capture. The algae that are not consumed by fish absorb carbon gas, eventually sinking to the ocean floor. King stated that if this method is spread over 3% of the oceans, it could remove 10 billion tons of carbon dioxide annually, equivalent to one-third of global emissions.

Bill Gates supports research efforts.

Projects like these attract the attention and financial support of renowned billionaires.

One of those billionaires is the co-founder of Microsoft, Bill Gates. Gates donated $300,000 to Silver Lining, as mentioned above.

Furthermore, Gates also supported a Harvard University initiative that proposed spraying calcium carbonate, a substance found in antacids, into the skies over Sweden. However, this project was canceled in its early stages due to protests from local communities.
