Global warming is related to species diversity

 Paleontologists have found that global warming has a positive effect on species diversity. Article (at the time of this writing, it has not been posted on the Internet) appeared in the scientific journal Proceedings of the National Academy of Sciences, and its summary results in Nature News.

In the study, researchers analyzed data on the diversity of the biosphere over the past 540 million years. As a result, it was found that the temperature peaks coincide with an increase in biodiversity. The researchers say that their results apply to the present time it is impossible — the fact is that the key factor is the rate of climate change. It is believed that they are now going too fast for organisms to adapt to them.

It is noteworthy that the new results are directly opposite to the results of a similar study in 2008. According to the researchers, the matter in difference techniques. In previous work, scientists analyzed information on all living things, which they are known. At the same time as the start and end points in the history of a species were taken, the oldest and the most recently known fossils.

According to the researchers, this approach ignores the fact that, due to geological features, some time intervals studied better than others. To get rid of the distortions to which this fact is brought into the analysis, the researchers chose only periods that were sufficiently well understood. As a consequence, the result has changed almost the opposite.
