	B.	Global temperatures have risen a little more than half a degree Celsius.
	C.	Plants that survive only in warm temperatures are starting to appear.
	D.	Biologists and ecologists are finding flooding in many parts of the world.

2.	According to the selection, one effect that a warmer climate has on mountaintops is that

	B.	that scientists are wrong in the way they are measuring the temperature of the globe
	C.	that the effects of global warming are not as disastrous as scientists and ecologists are claiming
