Global warming, its consequences
and
possible steps to be taken
Global warming is the phenomenon of continually rising average temperatures recorded in the atmosphere around the ground and oceans, observed the last two centuries,especially in recent decades.
This phenomenon is due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
1. Rising sea levels and ocean
Global warming leads to melting ice layers of Greenland and Antarctica, which, according to the pessimistic scenario, will increase water levels in the oceans with minimum 2 meters. So large tracts of coastal current (in many densely populated areas of the world) will disappear, with knock-on effects on population relocation.
2. Intensification of hurricanes and storms
One thing certain is that, as global warming has emphasized, have emerged stronger hurricanes and storms more violent.
3.Drought and desertification
Intensive agriculture leads to soil erosion and the loss of its ability to support the growth of vegetation. Unsustainable use of water reserves under the earth lead to soil degradation, while inappropriate irrigation increase the soil salinity. Obviously, higher temperatures accelerate desertification, especially deforestation.
4. The danger of total extinction
Optimistic estimates say that by 2050, more than one million of known species will disappear today. Pessimistic estimates, however, say that we are on the threshold of the 6th global extinctions that could become a reality before the end of this century!

• Global warming is the phenomenon of continually rising
average temperatures recorded in the atmosphere around the

from Earth.

large tracts of coastal current (in many densely populated areas of the world) will disappear,

4. Fight against global warming
• The crisis will be solved only if we, as
individuals, we take responsibility for it.
• Learning, teaching others, to do our best in
everyone to stop using so many resources and
especially not wasting them, getting involved
in public life and demanding change.

Solutions worldwide:
• Green energy - clean energy or energy
alternative to the classic, produced from
renewable sources clean.
• Identifying and stopping illegal logging activities
followed by actions of afforestation.
• Reducing emissions of greenhouse gases.
6. Individual solutions:
• Use economic lighting.
• When buying new appliances, choose the most
economical one.
• Support an environmental organization.
• Save hot water.
• Hybrid cars.
• Recycle.
7. Conclusion
• To avoid a bleak future of humanity, it is
important to understand that nature must be
protected.
