If the amount of incoming solar radiation that the Earth absorbs is greater than the amount of outgoing radiation the Earth emits to space, Earth's temperature will increase A decrease in Earth's average albedo would lead to more incoming solar radiation being absorbed by the sun Over the last 600,000 years, the highest pre-industrial concentration of carbon dioxide in atmosphere was _____ ppm. aprox 300 The loss of sea ice in the Arctic is an example of a [ Select ] , where an initial warming will cause there to be less sea ice which will decrease the albedo and lead to [ Select ] positive feedback loop, additional warming If you wanted to reconstruct ocean temperatures on short timescales (decades to centuries) with annual resolution, which of these archives would be the best target? corals What is the direction of the trend in Western U.S. snowpack over the last several decades? decreasing What is the current estimate for how much Earth's temperature will increase if the concentration of CO2 in the atmosphere is doubled? 2-4.5 degrees C An increase in temperature would cause the equilibrium line to __________ in elevation. move up A glacier will grow or advance if accumulation is ____________ than ablation. greater than What happens to sea-level when glaciers melt? sea level rises globally, local isostatic depression Earth's energy balance refers to the balance between incoming radiation from the sun, radiated emitted by the earth to space. A decrease in the concentration of greenhouse gases in the atmosphere would lead to _______________. a decrease in Earth's average temperature, a decrease in the amount of long-wave radiation that is absorbed by the atmosphere 00:02 01:41 When did Earth's current warming trend begin? 150 years ago because of fossil fuel use during the Industrial Revolution
