New Delhi, A more humid atmosphere than before, rising sea levels, relentless heat oriented drought in the US, crops destroyed by drought in Russia and Ukraine, rain scarcity in Somalia, flood threatening North Korea of food shortages and Finland recording highest rainfall in a single year in the last 150 years. Is the world worldwide is being influenced by climate changes that are taking place on earth.
The trend of climate change can already be seen. The mean temperature has rises, the quantity of sea ice has decreased in the north due to melting of Arctic glaciers, the snow cover has lessen, the ocean surface has rises, the water has become warmer, both high and low temperatures turned extreme more frequent than before.
Global scale researchers say that the signs are evident. The average temperature of the earth has increased by 0.8 degrees from the beginning of the 20th century. There is more water in the seas, as the water level is rising at a rate of three milimetres a year - 30 Centimeters in a century. In the Baltic Sea the impact is less because of isostatic uplift. But the ice is coming from the polar icecaps, which are melting faster than predicted. In Finland, the average temperature has risen at a rate of about one degree in 100 years. The greatest increase in warmth has been in the spring, and snows are melting earlier than before. The snow cover has become thinner, and the period has become shorter when lakes are covered with ice.
There has been record heat, record drought, and record amounts of rain. These weather functions have become usual events and these are taking place according to the predictions made by Climate scientists all around the world. They had predicted that extreme weather phenomena - heat waves, dry spells, tropical storms - will become more common as climate change sets in.
