[[snippet]]

The passage does not state or imply that temperatures are currently rising. We only know that climate change has caused detrimental effects on endotherms, but these results could be from either rising or decreasing temperatures.

Excellent!

The second sentence of the third paragraph tells us that endotherms are currently suffering drastic and detrimental effects because of climate change. The third sentence goes on to tell us that scientists cannot be sure that it is climate change that is the cause for these effects because the studies have been conducted over relatively short periods of time.

So, how is it that the author is able to say in the second sentence that climate change is indeed responsible for these effects? He or she uses the information in the first sentence to show that climate change over a very long period of time did indeed have a proven effect on endotherms.

Incorrect.

Incorrect.

[[snippet]]

Although it may seem that the author is unsure about the effects of climate change, she or he still states in the second sentence of the third paragraph that the effects of climate change on endotherms is drastic and detrimental. Although this seems like a paradox, this first sentence is crucial in explaining why it is not.

suggest that climate change is detrimental to endotherms
draw a parallel between the results of climate change in the past and its results in the present
show that the contradictory nature of information from the past does not allow scientists to draw conclusions about the effects of climate change on endotherms
imply that the current rise in temperatures is greater than the change that occurred during this period
provide proof that climate change has an effect on endotherms
