Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation, mitigate hail or disperse fog. The usual objective is to increase rain or snow, either for its own sake or to prevent precipitation from occurring in days afterward.
So as you can see any kind of weather modification raises unknown effects. You can image what could happen if we tried to modify not the weather but the climate, which are almost same thing.
In fact weather reflects short-term conditions of the atmosphere while climate is the average daily weather for an extended period of time at a certain location.
Yeppers, something I've learned about in recent days due to this:

A Secretive Experiment Released Salt Crystals Over San Francisco Bay—Could It Help Curb Warming?
The technology could make clouds reflect more sunlight, cooling the Earth below. But even the scientists leading the study say letting go of fossil fuels is a much-preferred response to climate change

Yes the consequences of GEOENGINEERING are unknown! Much better to work out the Climate Change issue in a natural way by reducing the use of fossil fuels. Believe me!Yeppers, something I've learned about in recent days due to this:

The lengths people will go through to keep oil & gas and find ways not to give Elon Musk anymore money!
In April 1938, Guy Callendar published his seminal paper showing that Earth’s land areas had warmed over the previous 50 years.
He also suggested that man-made Carbon Dioxide CO2 emissions had caused around half of the observed Anthropogenic Warming.
This happened 86 years ago.

Our fatal shortcomings as human beings have been that we treat the earth as just an object,” Grand Imam Nasaruddin Umar said. “The greedier we are toward nature, the sooner doomsday will arrive.” Then he prescribed the cure as laid out by their faith, which guides almost a quarter of humanity. Like fasting during Ramadan, it is every Muslim’s Fard al-Ayn, or obligation, to be a guardian of the earth. Like giving alms, his congregants should give waqf, a kind of religious donation, to renewable energy. Like daily prayers, planting trees should be a habit.
He is not alone in this country of more than 200 million people, the majority of them Muslims, in trying to kindle an environmental awakening through Islam. Top clergy have issued fatwas, or edicts, on how to rein in climate change. Neighborhood activists are beseeching friends, family and neighbors that environmentalism is embedded in the Quran.
Actually also in our Catholic religion the Gospel says to treat fine the Garden of Eden and to leave it better than when we entered it.

So we have the Pope and Imams on board... Just not the corrupt politicians.
All people of GOOD WILL independently from their Religious Faith, political color, race, sex, age and so on are WELCOME to fight the Climate Change issue.

A new paper in Nature says that it will be expensive to fix climate change... But much cheaper than not fixing it.
Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate and empirical uncertainty). These damages already outweigh the mitigation costs required to limit global warming to 2 °C by sixfold over this near-term time frame and thereafter diverge strongly dependent on emission choices. Committed damages arise predominantly through changes in average temperature, but accounting for further climatic components raises estimates by approximately 50% and leads to stronger regional heterogeneity.

Analysis of projected sub-national damages from temperature and precipitation show an income reduction of 19% of the world economy within the next 26 years independent of future emission choices.

Plastic-production emissions could triple to one-fifth of Earth’s carbon budget – report
Exclusive: By the middle of the century, pollution from plastic industry could ‘undermine world’s effort’ to control climate crisis
www.theguardian.com
By the middle of the century, global emissions from plastic production could triple to account for one-fifth of the Earth’s remaining carbon budget, an analysis has found. The stunning new estimates from Lawrence Berkeley National Laboratory, published Wednesday, provide yet more evidence the plastic industry is “undermining the world’s efforts to address climate change”, said Heather McTeer Toney, executive director of the Bloomberg Philanthropies’ Beyond Petrochemicals campaign, which helped fund the new report. ‘Basically it’s a propaganda campaign.’ The production of plastic, which is made from fossil fuels, is greenhouse gas-intensive. Coal, oil or gas must first be mined or extracted, and then those materials must be refined and processed in another emissions-heavy procedure. In some cases, other chemical compounds such as formaldehyde must also be produced, creating more pollution.

Global heating pushes coral reefs towards worst planet-wide mass bleaching on record
The percentage of reef areas experiencing bleaching-level heat stress is increasing by about 1% a week, scientists say
www.theguardian.com
Global heating has pushed the world’s coral reefs to a fourth planet-wide mass bleaching event that is on track to be the most extensive on record, US government scientists have confirmed.
Some 54% of ocean waters containing coral reefs have experienced heat stress high enough to cause bleaching, the National Oceanic and Atmospheric Administration’s Coral Reef Watch said.
A global bleaching event is declared when at least 12% of corals in each of the main ocean basins – Pacific, Atlantic and Indian – experience bleaching-level heat stress within a 12-month period. The declaration also requires confirmed reports of bleaching.
Coral Reef Watch also confirmed the world’s largest coral reef system – Australia’s Great Barrier Reef – had been through its most widespread heat stress event on record in 2024.
The first global bleaching event happened in 1998 with 20% of the ocean’s reef corals exposed to a level of heat stress high enough to cause bleaching. The second event, in 2010, saw 35% reaching that threshold, and the third from 2014 to 2017 peaked at 56%.
Dr Derek Manzello, the Coral Reef Watch director, told the Guardian the current bleaching was likely to surpass the previous most widespread event soon “because the percentage of reef areas experiencing bleaching-level heat stress has been increasing by roughly 1% per week”.
NOAA’s threshold for the onset of bleaching relates to the amount of accumulated heat corals are facing at any given time, known as degree heating weeks (DHWs).
For example, a 1 DHW is accumulated if corals are subjected to temperatures 1C above the usual maximum for seven days. Coral Reef Watch considers 4 DHWs as a bleaching threshold.

Coral reef ecosystems
Coral reefs are some of the most diverse ecosystems in the world. Coral polyps, the animals primarily responsible for building reefs, can take many forms: large reef building colonies, graceful flowing fans, and even small, solitary organisms. Thousands of species of corals have been discovered...
From the mentioned article:
Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection. Fishing, diving, and snorkeling on and near reefs add hundreds of millions of dollars to local businesses. The net economic value of the world’s coral reefs is estimated to be nearly tens of billionsoffsite link of U.S. dollars per year. These ecosystems are culturally important to indigenous people around the world.
As I informed TMC, 2 days ago we were close to reach a Global 365-day Temperature Deviation of 1.6°C. I am sorry to inform you that today we have reached a Global 365-day Temperature Deviation of 1.6°C.
We have overtaken the threshold of 1.5°C set by the Agreement of Paris for the Global Temperature Deviation!
This is bad news. Please don't look up this post.

Xi Thinks China Can Slow Climate Change. What if He’s Right?
https://www.nytimes.com/2024/04/19/opinion/china-climate-xi-jinping.html?unlocked_article_code=1.lk0.53LQ.N1vEW5RPoRGj
It has already begun. In recent years, the transition away from fossil fuels has become Mr. Xi’s mantra and the common thread in China’s industrial policies. It’s yielding results: China is now the world’s leading manufacturer of climate-friendly technologies, such as solar panels, batteries and electric vehicles. Last year the energy transition was China’s single biggest driver of overall investment and economic growth, making it the first large economy to achieve that.
This raises an important question for the United States and all of humanity: Is Mr. Xi right? Is a state-directed system like China’s better positioned to solve a generational crisis like climate change, or is a decentralized market approach — i.e., the American way — the answer?
Climate change is, similarly, a global problem, one that threatens our species and the world’s biodiversity. Where do Brazil, Pakistan, Indonesia and other large developing nations that are already grappling with the effects of climate change find their solutions? It will be in technologies that offer an affordable path to decarbonization, and so far, it’s China that is providing most of the solar panels, electric cars and more. China’s exports, increasingly led by green technology, are booming, and much of the growth involves exports to developing countries.
China’s government knows that it must make this green transition out of rational self-interest or risk joining the Soviet Union on history’s scrap heap, and is actively positioning itself to do so. It is increasingly led by people with backgrounds in science, technology and environmental issues. Shanghai, the country’s largest city and its financial and industrial leading edge, is headed by Chen Jining, an environmental systems expert and China’s former minister of environmental protection. Across the country, money is being poured into developing and bringing to market new advances in things like rechargeable batteries and into creating corporate champions in renewable energy.
So it is crucial for Americans to recognize that, for most of the world, perhaps for all of us, China’s ability to provide low-cost green technology is, on balance, great news. All of humanity needs to move toward renewables at a huge scale — and fast. America still leads in innovation, while China excels in taking frontier science and making its application in the real world cost-effective. If American politicians, investors and businesses recognize that climate change is humanity’s biggest threat, that could open pathways for diplomacy, collaboration and constructive competition with China that benefit us all.
