WebbSeveral climate models accurately simulate the global warming of the late 20th century when the radiative effects of increasing levels of human-induced greenhouse gases (GHG) and sulfate aerosols are taken into account. However, the warming in the early part of the century has not been well simulated using these two climate forcings alone. Webb14 apr. 2024 · Significant leaps in understanding volcanic eruptions and their consequences often occur during and shortly after well-observed eruptions. For example, the 1980 Mount St. Helens eruption highlighted the hazards from a large flank failure and a lateral blast (Miller et al. 1981), the 1991 eruption of Pinatubo enabled the climatic … fisheries queryWebbThings that change the balance between incoming and outgoing energy in the climate system are called forcings. Natural forcings include volcanic eruptions. Manmade forcings include air pollution and greenhouse gases. A climate forcing, such as greenhouse gas increases, may trigger feedbacks like the loss of sunlight-reflecting ice. fisheries qld contact
