Deteriorating nature of our planet is going to run. Sea level is rising. The number of natural disasters is increasing. Organism - are animals and plants are becoming extinct. The climate is becoming contaminated. Pole covered with snow and glaciers are melting. Water, forest and land are shrinking. They are the face of climate change. Identify the magnitude of these faces and therefore required to cope with the Earth Day theme this time "in the face of climate change 'has been fixed.
Global Warming:
In the last century, the earth's atmospheric and oceanic temperatures slowly but steadily increased. Every single human activity such as cutting trees or vehicle usage contributes to this process.
Climate Change:
Global warming will have on the Earth's weather system adds the impact of climate change. Like - like air and water are becoming hot, unexpected changes in Earth's climate cycle is visible. The world today has become a major problem for the side effects.
Warm the heart: Greenhouse Effect
- Solar energy reaches Earth as sunlight passing through the atmosphere.
- A third of the energy returns to space.
- The rest is absorbed by the Earth.
Which is becoming progressively warmer Earth.
Effect of change:
One billion people in the world due to climate change threatens to affect. This change will impact negatively on the economic situation.
Changes in weather systems:
World climate change will speed up the process. Excess heat will never ever will create the conditions for floods and droughts. Storm - storm, cyclone and avalanche will begin rapidly.
Sea level:
Increased melting of ice Ctranon heat is intensified. In surface waters of the ocean is increasing. According to a study, in the past two decades, the average global sea level has increased by eight cm. It is estimated that by the end of this century may rise from 10 to 90 cm. In such a situation will threaten the sinking of coastal areas.
Drinking water and food crisis:
1 to 2 billion people in the world are grappling with the problem of water. As a result of climate change, increasing drought and cut the forest can be substantial in this issue. Melting glaciers to affect a large population of the world is in danger. Because of the extreme heat and drought have affected agricultural production, food security of the world to hell.
Diseases and health crises: climate change and the threat of infectious diseases may be wider geographical distribution. According to an estimate by the World Health Organization, in 2000, the death toll due to climate change, increased by 1.5 million. Qualitative growth is expected in the future.
Manipulating ecosystem: the human development process water, air pollution and climate change and the profound impact of the housing can be eliminated. Glaciers, coral reefs, mangroves, tropical forests, polar and alpine ecosystems can cause severe damage to many natural systems.
Crisis on the species:
Climate change, loss of biodiversity by 2050, easing would be visible everywhere. Which species are on the verge of extinction, will increase the risk for them.
What if global temperatures:
0-1 degree rise -
Increase crop yields in developed countries altitude, the smaller glaciers end of the world, the water crisis in many areas, maritime threat to coral reefs.
Rise 1-2 degrees -
The decline in crop yields, curry increase in the number of people at risk of suffering from starvation, most of Africa and western Asia, Amulcul changes in water availability, Amazonian rain forests at risk of extinction, in large numbers, the nature of the challenge to save the ecosystem , floods, droughts, storms and increase the intensity of heat.
2-3 degree rise -
Many species may be extinct organisms, hurricane damage in the U.S. doubled.
Rise 3-4 degrees -
Despite strong carbon fertilization crop yields in many less developed regions.
4-5 degree rise -
Unexpected decline in crop yields, rising sea levels Mumbai, Kolkata, London, Shanghai, New York, Tokyo and Hong threat.
Fireball:
Carbon dioxide is deposited in the atmosphere for centuries. The momentum of industrialization 70 per cent of the total accumulated gas emissions by developed countries this has been.
By 1731 the volume of gas emitted by major countries per cent of all emissions.
