Aerosols are tiny particles suspended in the air. Most occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray (Figure 1). Human activities, such as the burning of fossil fuels and the alteration of natural surface cover, also genera...
SO2 emissions (SO2 is sulfur dioxyde), which are aerosol precursors (aerosols “cool down” the climate), are also represented. The IS92a scenario is an older scenario that was used for the 1995 IPCC report. Between the most “optimistic” and the most “pessimistic” of...
In what feels like a predictable turn, scientists say injecting the stratosphere with reflective aerosols would not help climate change enough to balance out the unwanted side effects. While the idea sounds outlandish, it’s a surprisingly old one, and it’s not the wildest thing ever suggested...
the science began to mature as researchers unearthed the most prominent factors such as the cooling influence of aerosols and the warming influence of greenhouse gases like carbon dioxide —
There are other natural climate drivers, also known as “climate forcings”. Large volcanic eruptions qualify as climate forcings because sulfur dioxide emissions from eruptions can have a temporary cooling effect. Sulfur dioxide converts into sulfuric acid that condenses into aerosols in the atmosphe...
You can also scribble your own rising, falling, or squiggling line representing different levels of intervention across the decades to see what might happen as reflective aerosols are released. I tried to simulate what’s known as the “termination shock” scenario,...
The asteroid impact caused massive fires, tsunamis and an "impact winter" by ejecting dust and aerosols into the atmosphere, blocking sunlight and disrupting the climate. This led to a collapse in photosynthesis, affecting the food chain. What other factors might have contributed to the dinosaurs'...
These aerosols also have a cooling effect on the Earth's climate by reflecting solar radiation back into space. Volcanoes release substantial amounts of CO2, a well-known greenhouse gas contributing to global warming. While volcanic CO2 emissions are relatively small co...

the dramatic extremes in temperature and sea ice extent are best explained as natural variabilityon top of long-term warming. In other words, they sit within a natural range that is rapidly shifting upwards as a result of global warming. Emissions ofsunlight-reflecting aerosols from shippingalso ...
