I generally do not like to place quantitative material at the end of lecture; if(MSFPhover) { MSFPnav5n=MSFPpreload("_derived/software.htm_cmp_expeditn010_hbtn.gif"); MSFPnav5h=MSFPpreload("_derived/software.htm_cmp_expeditn010_hbtn_a.gif"); } There are reasons to believe that the climate response could be much weaker than that to a CO2 doubling from current values. 3) Challenge in applying past climate sensitivity to future climate The details of this “challenge” are quantitative and come at end of lecture. // --> . I generally do not like … Please visit www.CO2Science.org for even more information about wonderful CO2.. Well wonder no more, as this site allows you to delve into the continental make up of any time in the past! Evolution and Climate - posted in Biology: I was looking through the earth science forum and there is a discussion on Global Warming. (parseInt(navigator.appVersion) >= 3 )) || Computer climate models suggest that there will not just be a uniform change in temperature, but large changes in atmospheric circulation patterns. To get some perspective on timing, that's just over 200 million years before dinosaurs began to roam the Earth. Certain types of rocks, such as coals, which need abundant rainfall, form under certain … CSE's Environment Education Unit targets school, college and university students, as well as interested educators and parents. climate history to better predict what may happen in the future: "The past is the key to the future". West Virginia today is mostly an erosional plateau carved up into steep ridges and narrow valleys, but 300 million years ago, during the Carboniferous Period, it was part of a vast equatorial coastal swamp extending many hundreds of miles and barely rising above sea level. The official website of Northwest Missouri State University located in Maryville, Missouri. Let’s apply these two climate sensitivities to future temperature Both future scenarios assume: a) CO 2 doubles: i.e., ∆F This Legend indicates which lithologic indicators of climate would be expected to occur in the five different climatic zones (Tropical, Arid, Warm Temperate, Cool Temperate, Cold) shown on the paleoclimatic reconstructions. Method Used to Determine Ancient Climates . During the last 2 billion years the Earth's climate has alternated between a Basically, since the center of a supercontinent would be so far away from the oceans, would it be a dry barren wasteland like death valley due to all the water draining away from the center and towards the oceans, or could water end up trapped in the region, evaporating only to rain back down? Consequently, the same variations in solar activity may have caused larger climatic changes (temperature, precipitation) during the Pleistocene than during the Holocene. // -->
