what I F ? Suppose you had an organic molecule such as cysteine (see Figure 4.9, sulfhydryl group example), and you chemically removed the NH2 group and replaced it with COOH. Draw the structural formula for this molecule and speculate about its chemical properties. Is the central carbon asymmetric before the change? After?
Radiative forcings for shortwave agents in current climate vs preindustrial (best estimates) 2 ● CO2 radiative forcing is currently: 1.68 W/m ● Solar radiation changes: 0.05 W/ m 2 ● Land cover changes ● Aerosol direct effect ● Aerosol indirect effect 2 Total GHG: about 3 W/m Shortwave forcings about -1 W/m 2 ● With significant scientific uncertainty here 2 Best guess of total forcing: 2.3 W/ ○ Making earth get hotter Earth has been warming over the last 150 years ● Due to greenhouse gases CO2 is still the main problems ● Global ● “Global warming”- distributed globally ○ Why temp has to change
