Little Ice Age

We have every reason to expect the most dramatic consequencesof global warming, both predictable and unpredictable.Doing all in our power, putting in every effortto decrease the speed of global warming is, no doubt, the most crucialproblem, mankind is faced with today.

It should not be forgotten, however, that the Earth has already survivedcli­mate changes that were not less dramatic for its inhabitants.The nature of the


other well-known climate change was diametrically opposed to global warming. It was global cooling. The most recent period of this kind is called the Little Ice Age. Althoughthere is no scientifically agreedopinion concerning the begin­ning of the Little Ice Age, there is a consensus that it only ended in the mid-19th century.

The Little Ice Age brought bitterly cold winters to many parts of the world. Rivers and lakes were frozen, fields were covered with a thick layerof snow, which inevitablyaffected the crops. The most severelyaffected social group of people was the peasants. Some historians assertthat famine, diseases and massive deaths resulted in important political events, such as the French Revo­lution of 1789.

Beginning with 1850, the world's climate began warming again and the Little Ice Age may be said to have come to an endat that time. Some global warming critics believe that the Earth's climate is still recovering from the Little Ice Age and that human activity is not the decisivefactor in present temperature trends.

However, the prevailing scientific opinionon climate change is that warm­ing over the last 60 years is caused primarily by the increased proportion of СОг in the atmosphere dueto human activity. History shows that we have a good chance to survive global warming. A lot depends on ourselves.

If anyone had a bet that there is no life on any other planet except for the Earth, he would be most likely to lose it because astronomers have recently discovered a planet that actually has all the necessary properties for life to exist on it.

The planet is five times heavier than the Earth, and orbits a Red Dwarf (a little sun). In spite of its small size, it emits enough heat to keep temperature of the planet's surface similar to that of the Earth's.

There is water on the planet, and correspondingly some kind of atmo­sphere. That is why the scientists do not eliminate the possibility of some forms of life on it. It would be extremely difficult, however, to find out whether it is really so.

The planet is far beyond the scope of the solar system at a distance of about 200 trillion kilometers from the Earth!
