What can turn global warming for humanity?

Iceberg.

Extreme weather conditions do not cease to amaze in almost all parts of the world. A frequent natural disasters entail, as a rule, are the inevitable economic consequences.

As such, the Earth's climate will become more humid. In this case, the amount of precipitation is not evenly distributed across the planet. In areas where it falls so today sufficient rainfall will drop them even more. In regions with a deficit of moisture during the dry Participation.

According to scientists in the twentieth century, sea levels rose by an average of 0.1-0.2 meters. According to experts, at the end of the XXI century sea level rise is to reach 1 meter. In this case, the most vulnerable, of course, will be coastal areas and small islands of the Earth. At risk would be the Netherlands, Great Britain, and the small islands of Oceania and the Caribbean. In addition, high tides will occur more frequently will increase shoreline erosion.

Species and ecosystems have long started to react to climate change. Migratory birds such as steel spring arrive earlier and much later to fly in autumn. The probability of extinction of 30-40% of the species of different plants and animals as well as their environment will change much more quickly than they would adapt to the changes. In the case of an increase in temperature of 1 ° C will modification of wood. And because the forests are natural carbon storage, change the type of forest will be marked by the appearance of large amounts of carbon.

Impact of warming on the level of agricultural productivity is very ambiguous. Thus, in some areas where the temperate climate, productivity may increase with small increases in temperature, but decrease with significant temperature changes. In the tropics and subtropics, crop yields in general, as they note, will be reduced. But the biggest shock facing the poorest countries, which are least prepared to experience all of climate change.

Another of the consequences resulting from climate change could be significant shortage of drinking water on the planet. In arid regions (Central Asia, Australia, the Mediterranean, South Africa, etc.), the situation becomes more complicated because of a significant reduction in rainfall.

Due to the melting of glaciers flow down all the major waterways of Asia — Brahmaputra, Yellow, Indus, Salween and the Yangtze. Water scarcity will touch not only the health of people and the level of agricultural development, but also increase the likelihood of political disputes and international conflicts over access to certain waters.

Also, climate change, the researchers predicted, would increase the risk to health of all people of the world and especially those sections of the population who are less assured. Thus, a gradual reduction in food production would inevitably lead to malnutrition and starvation. Abnormal temperatures can cause acute cardiovascular, increasing incidence of respiratory and other diseases.

In the end, the temperature rise threatens change the geographical distribution of any species that are vectors of disease. With climate change, heat-loving animals and insects (such as encephalitis or mites malarial mosquitoes) will spread more and more in the northern regions, while the people living in these areas, there will be no immunity to new diseases.
