The website discusses the potential of geoengineering to mitigate the effects of El Niño by using aerosols to brighten clouds and create a cooling effect, based on simulations and past events like the Australian wildfires.
Infact verdict: True (86/100).
The claims regarding the use of aerosols and marine cloud brightening to influence climate patterns, such as El Niño and La Niña, are generally supported by scientific evidence. The concept of using aerosols to brighten clouds and create cooling effects is well-documented in scientific literature and supported by multiple reputable sources. However, some claims are based on simulations, which introduces a degree of uncertainty. Overall, the evidence suggests that these geoengineering techniques have potential but require further research to fully understand their impacts and effectiveness.
Individual Claims

True
Science
Adding aerosols to the atmosphere over a particular patch of the Pacific Ocean can increase and brighten clouds in the region, creating a cooling effect.
The claim is supported by multiple sources, including a detailed explanation of marine cloud brightening, which involves adding aerosols to increase cloud reflectivity and create a cooling effect. This method is discussed in scientific literature and is considered a potential geoengineering technique to mitigate global warming. Sources such as Science News and the Marine Cloud Brightening Research Program corroborate this claim.

Science
New computer simulations show that adding aerosols can trigger atmospheric changes that might reduce the strength of an El Niño event.
The claim is supported by simulations and studies indicating that marine cloud brightening could potentially reduce the strength of El Niño events by altering atmospheric conditions. This is discussed in sources like UC San Diego and NASA, which provide evidence of the potential effects of aerosols on El Niño. However, the evidence is based on simulations, which introduces some uncertainty.

Science
Marine cloud brightening proposes that certain aerosols injected into the atmosphere could brighten the ocean’s cloudiest regions, making them whiter and more reflective.
The claim is well-supported by multiple sources, including Wikipedia and the Marine Cloud Brightening Research Program, which describe the process and goals of marine cloud brightening. This technique involves using aerosols to increase cloud reflectivity, thereby cooling the planet. The evidence is consistent and comes from reputable sources, supporting the claim's validity.

Injecting particles from June through the following February led to the strongest cooling of the 2015–2016 El Niño event.
The claim is supported by evidence from Science News and Wikipedia, which discuss the use of marine cloud brightening to reduce the intensity of the 2015–2016 El Niño event. The timing of particle injections is noted to have significantly affected the cooling effectiveness. However, the evidence is primarily based on simulations, which introduces some uncertainty.
