A research team claims to have found evidence that China has successfully changed its climate on at least one occasion.
The document, written by the researchers of theTsinghua Chinese University, denounces the fact that the Chinese authorities have managed to alter the climate through cloud seeding technology.
It happened with certainty this year, the report said, in Beijing for the celebration of the centenary of the Communist Party (CCP). Thousands of participants in the celebration found the sky clear and less pollution: a kind of "blessing from heaven", but of anything but divine origin.
Altering the climate in China, a success story
Cloud seeding technology consists of shooting silver iodide particles into clouds, causing water droplets to clump together and substantially change the climate on a local scale.
It is not the country's first attempt at this technology, but it appears to be the most successful and largest-scale example to date in the world. A result that adds credibility to government reports according to which the China it will expand its climate-altering program to nearly 9 million square kilometers (5,5 million square miles) by 2025. It's a larger area than the whole of India.
Clues and evidence
The researchers' paper refined the evidence that the change did indeed occur. The team attached to the document not only eyewitness accounts of rockets launched into the sky from the mountains just outside the capital, but also the discovery of rocket residues after the July 1 event.
Pollution in Beijing in the days leading up to the celebration was particularly serious. Yet the pollution index in the area went from "moderate" to "good" on the day of the event, complete with providential rain in the middle of the day. The success of the climate-altering operation could lead to questions and concerns about the wider use of such technology, especially in the military.
In fact, several researchers are very skeptical about the long-term effects of cloud seeding. Currently (especially in the Arabian Peninsula) it has only proved effective in the short term to mitigate drought. Furthermore, altering the climate of an entire country is an unknown factor also for the effects on neighboring countries: if making it rain effectively on one's territory worsens the drought in the neighboring one, the diplomatic crisis is on the horizon.
