Document Summary
What determines earth"s surface temperature? the sun! Solar radiation reflected, absorbed, and re-radiated as long-wave heat. Earth"s radiation balance increased concentrations of gases trap heat incoming solar radiation = 100% Warming of climate is unequivocal - 5th ipcc report. Scientific study of interactions between organisms and their environment (biotic and abiotic) interactions across many levels of biological interaction/organization from molecules to organ systems. Albedo - capacity of a surface to reflect the sun. Weather = temp, humidity, wind, cloud cover, precipitation, etc. Global climate change: directional change in climate over at least 3 decades. Plants intake co2, when plants add leaves and roots, they suck co2 out of the air when co2 is at its lowest, it is doing heavy growing. Why is 0. 8c more for life than it seems? it is the global average. Extreme events matter to organisms time frame is short (130 years) this is measured over the beginning of global industrialization.
