According to figure 4-1, temperature in the past few hundred years has spiked with CO2 levels following closely behind temperature. This spike has remained relatively constant and has yet to see the usual drop as seen in previous time periods. In the second figure given (which depicts the past 120 years specifically), it seems as though CO2 is increasing along with temperature with little to no lag. And as of more recently (past 60 years), it looks as though CO2 might be increasing before the typical temperature increase. This is unusual given how CO2 increases typically follow temperature increases.

When the water enters near Greenland and Iceland, that water dumps its heat into the air over Northern Europe, warming the region.
6-3: What do computer forecasts suggest would happen if the Gulf Stream “conveyor belt” were to stop?
Computer simulations predict that Northern Europe would become colder within decades if the conveyor ever stopped
6-4: Describe the controversy over this report in Nature that suggested the Gulf Stream might be slowing down.
Since the study only has five sets of measurements, some argue that it’s not nearly enough information to claim something's happening to the Gulf Stream. Others argue that the measurements in the Atlantic are so slight, they could simply be an error in measurement.

7-9: Describe the nature of the consensus among scientists at the American Meteorological Society meeting on the impact of climate change on hurricanes.
There didn’t seem to be a general consensus about the impact of climate change on hurricanes. Many different individuals disagreed with each other, citing their reasonings on
