THE EFFECTS OF CLIMATE CHANGE:
·GLOBAL WARMING:
At the end of the nineteenth century, scientists have observed a gradual increase in the temperature of the planet's surface. This increase has been between 0.5 º C and 1.0 º F. The ten warmest years of the twentieth century occurred between 1985 and 2000.
This warming has reduced the snow-covered areas in the northern hemisphere, and has caused the Arctic Ocean have melted some ice masses. In Antarctica have separated portions of ice and are melting.
·CLIMATE:
Global warming has caused a temperature increase at the surface of the earth, causing the polar thaw. The sea level has risen 4-8 inches and will continue to increase. The magnitude and frequency of rainfall has also increased due to the evaporation of surface water caused by the increase in temperature. Scientists say the surface temperature can reach up to 4.5 º F increase in the next 50 years (2001-2050), and up to 10 º F during this century. This increase in water evaporation will result in an increase in the intensity and frequency of hurricanes and storms.
You can see these video of climate changes:
·HEALTH:
An increase in the temperature of the Earth's surface will result in an increase in respiratory and cardiovascular diseases, infectious diseases caused by pests and tropical mosquito.
-The cardiovascular and respiratory systems are affected because, under hot, the person must exert more effort to perform any activity.
In the tropics extend mosquitoes and other pests responsible for dengue, malaria, cholera and yellow fever in the tropics affect a larger portion of the world population, increasing the number of deaths from these diseases.
·TERRESTRIAL ECOSYSTEMS:
The result of global warming will be:
- Extend the tropics to higher latitudes, and the region of pine forests extend into areas that now form part of the tundra and taiga. In losing its moisture soils due to evaporation, many areas could be covered with dry vegetation, widening the desert region of the planet.
- In the continental plain due to water shortages as a result of the increase in temperature could make these regions (such as the pampas of Argentina and the Great Plains of North America) on land unsuitable for farming.
·COASTAL ECOSYSTEMS:
-As coral reefs, sandpipers systems, estuaries, and others, would be affected, and that the sea level rise would inundate coastal wetland areas. The buildings very close to the coast could be affected by wave action, which could flood its foundations.
If we want to live in a better world we must reduce pollution and contamination in our cities. Because if not different places in the world are going to be affected by climate change in the future.
Now, could you answer these questions?:
1-. List five ideas to prevent further pollution of our planet.
2-. What do you think about global warming?
3-. Can you tell me what has been the hurricanes and earthquakes around the world recently?
4-. What cities will be flooded if the sea level would rise?
5 -. How can we stop this catastrophe?
