  1. What did you do in lab today? Temperature:  My group did temperature, as seen on ICON Precipitation:  rising global temperatures are driving major shifts in precipitation snow harms crops by allowing deep soil freezing-snow acts as a insulator which protects soil from freezing. Iowa city is seeing more extreme precipitation, 50% increase in days with more than 4 inches of rain bigger storms = more flooding  regionally there has been more precipitation more floods when it rains --> more drought stress when it doesn't  wet times wetter, dry times drier.  precipitations has increase in inches, numbers of days, and extremities because of an increase in global temperature.  Ag & Plant Life:  We know climate change is happening because Iowa temperatures have increased 1 degree since 1980. Iowa now gets about 4 more inches of rain per year. heavy rainstorms are happening more often. longer growing seasons and increased temperatures allow oppo...

  1. What did you do in lab today? Climate Change  1. What are the primary points in the video? Climate change is not a future problem, it's happening now and affecting millions of people. the documentary showed how burning fossil fuels, deforestation, and industrial farming are major contributors to global warming. Political and economic systems often slow down action, even when solutions already exist. 2. What are the major issues? Not enough people or leaders are taking this issue seriously. Developing countries will suffer the most, even though they contribute the least to the problem. We might reach a point where the damage can't be reversed. 3. What questions do you want us to teach you? What I can personally do to make a difference. Is the world on track to meet the goals from climate agreements?  How can countries switch to renewable energy sources effectively? AI affecting Climate Change Comparisons of Climate Trends  Data collection for Climate Change Corpo...

   1. What did you do in lab today? Water Cycle Evaporation, condensation, precipitation Transpiration Sublimation and De-sublimation Weather occurs in the Troposphere Weather is short term, climate is long-term How did we forecast weather before modern technology? old wives tales Joints hurt biting flies smell the rain Why does weather typically come from the west? direction of rotation of Earth Less dense = warm more dense = cold As the sun comes up, air "warms" up and moves creating a convection cell. Yes, that same convection cell that makes plates move it is windiest when the sun is at it's peak so early afternoon  Air pressure: how much weight the air is pressing down on earth Which brings the moisture? High Pressure vs Low Pressure Low pressure system is when storms are happening or anything other than sunny, pressure is leaving High pressure system is when the warm air is coming down, pressure increases heat rises, cool sinks  Warm Front:  where a warme...
