200 megaton https://en.wikipedia.org/wiki/1883_eruption_of_Krakatoa https://en.wikipedia.org/wiki/1883_eruption_of_Krakatoa Such a huge asteroid may be exactly what we need to slow down global warming - fighting one catastrophe with another: "In the year following the 1883 Krakatoa eruption, average Northern Hemisphere summer temperatures fell by as much as 1.2 °C (2.2 °F).[12] Weather patterns continued to be chaotic for years, and temperatures did not return to normal until 1888.[12] The record rainfall that hit Southern California during the water year from July 1883 to June 1884 – Los Angeles received 38.18 inches (969.8 mm) and San Diego 25.97 inches (659.6 mm)[13] – has been attributed to the Krakatoa eruption.[14] There was no El Niño during that period as is normal when heavy rain occurs in Southern California,[15] but many scientists doubt that there was a causal relationship.[16] The Krakatoa eruption injected an unusually large amount of sulfur dioxide (SO2) gas high into the stratosphere, which was subsequently transported by high-level winds all over the planet. This led to a global increase in sulfuric acid (H2SO4) concentration in high-level cirrus clouds. The resulting increase in cloud reflectivity (or albedo) reflected more incoming light from the sun than usual, and cooled the entire planet until the suspended sulfur fell to the ground as acid precipitation."
