Global Warming vs. Ice Period

The controversial assumption was introduced recently: regardless global warming occurrence and related species diversity decline, scientists emphasize that increasing temperature affect the number of species positively. The entire retrospective of biological investigation stresses that global warming periods led to enlargement f animals’ number unlike global cooling eras. The research covered a timeline of nearly 540 million years.

The conclusion states that peaks of temperatures corresponded to species’ increase. In contrast, the controversy of this statement does not fit contemporary situation, when global warming crucially influences on animals’ population and variety decline. Here is the time to consider the speed of climate changes. The key thing is that in previous periods climate conditions changed with much slowed speed than nowadays, and, therefore, animals and plants had more time to adapt to new environment. To date, global warming process occur faster, which takes away any opportunity to fit for natural habitat, including wildlife.

The brightest example is the Arctic meltdown. In 2012 total area of ice in the Arctic Ocean shrank to a record low in the history of observations. In practice, such a measurement was made by Japanese scholars, who even found this situation beneficial. The melting of Arctic lands releases a route for Japanese sailors and trade ships to Europe, the largest trade market on the planet. A new “warm” phase of Arctic development was recorded in 2011 particularly.

In addition, several announcements about global cooling period were made this year. On April, a member of Russian Antarctic expedition, Vladimir Lalenkov, pointed out that a next ice period will occur in 10-12 thousand years, after interglacial phase will come to an end. In fact, the mankind has already survived the half of it.
