What evidence can you find that GCMs are getting better? For example, could the change in the IPCC prediction from 3.0  1.5 C to 1.4 C to 5.8 C be considered an improvement? Explain.
 
  What will be an ideal response?

Question 2

The average kinetic energy per molecule in an ideal gas at 0 C is zero.
 
  What will be an ideal response?

Answer to Question 1

The change does represent an improvement in the prediction because it clearly
treats the upper and lower ends of the range differently. This is due to changes in the
models that give them greater believability, in particular improvements in the ocean
atmosphere interface and a substantial increase in the number of grid volumes used in the
calculations.

Answer to Question 2

Absolutely not. At 0 C, the absolute temperature is 273 K. There is plenty of
kinetic energy at this temperature.

Though methadone is often used to treat dependency on other opioids, the drug itself can be abused. Crushing or snorting methadone can achieve the opiate "rush" desired by addicts. Improper use such as these can lead to a dangerous dependency on methadone. This drug now accounts for nearly one-third of opioid-related deaths.
