Global Warming
Global Warming is a dramatically urgent and serious problem. We don't need to wait for governments to find a
solution for this problem: each individual can bring an important help adopting a more responsible lifestyle:
starting from little, everyday things. It's the only reasonable way to save our planet, before it is too late.
Global Warming effects
Green house gases stay can stay in the atmosphere for an amount of years ranging from decades to hundreds and
thousands of years. No matter what we do, global warming is going to have some effect on Earth. Here are the 5
deadliest effects of global warming.
1. Spread of disease
As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them.
Indeed some scientists believe that in some countries thanks to global warming, malaria has not been fully
eradicated.
2. Warmer waters and more hurricanes
As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes.
3. Increased probability and intensity of droughts and heat waves
Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves. Africa will receive the worst of it, with more severe droughts also expected in Europe. Water
is already a dangerously rare commodity in Africa, and according to the Intergovernmental Panel on Climate
Change, global warming will exacerbate the conditions and could lead to conflicts and war.
4. Economic consequences
Most of the effects of anthropogenic global warming won’t be good. And these effects spell one thing for the
countries of the world: economic consequences. Hurricanes cause do billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these.
5. Polar ice caps melting
The ice caps melting is a four-pronged danger.
First, it will raise sea levels. There are 5,773,000 cubic miles of water in ice caps,
glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today
the seas would rise about 230 feet. Luckily, that’s not going to happen all in one go! But sea levels will
rise.
Second, melting ice caps will throw the global ecosystem out of balance. The ice caps are
fresh water, and when they melt they will desalinate the ocean, or in plain English - make it less salty. The
desalinization of the gulf current will “screw up” ocean currents, which regulate temperatures. The stream
shutdown or irregularity would cool the area around north-east America and Western Europe. Luckily, that will
slow some of the other effects of global warming in that area!
Third, temperature rises and changing landscapes in the artic circle will endanger several
species of animals. Only the most adaptable will survive.
Fourth, global warming could snowball with the ice caps gone. Ice caps are white, and reflect
sunlight, much of which is relected back into space, further cooling Earth. If the ice caps melt, the only
reflector is the ocean. Darker colors absorb sunlight, further warming the Earth.
And the effects of rising temperatures aren’t waiting for some far-flung future. They’re happening right now.
Signs are appearing all over, and some of them are surprising. The heat is not only melting glaciers and sea
ice, it’s also shifting precipitation patterns and setting animals on the move.
Some impacts from increasing temperatures are already happening.
• Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice
sheets covering West Antarctica and Greenland, and Arctic sea ice.
• Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their
numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
• Sea level rise became faster over the last century.
• Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
• Precipitation (rain and snowfall) has increased across the globe, on average.
• Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have
chewed up 4 million acres of spruce trees.
