Google Earth Engine protects forests

 Google Inc. presented at the meeting of the UN Climate in Cancun, a new technology for the protection of tropical forests.
This technology will be an important tool for governments and will further strengthen relations and trust between rich and poor nations.
According to a report in Reuters, the scientists via satellite platform can monitor real-time changes occurring in tropical forests.
The platform Google Earth Engine forests collect images from satellites to get the U.S. and France and stored in open database sharing.
So the scientists via computer can monitor and record changes that occur in forests.
It is an important weapon for the protection of forests, Google Earth Engine.
Noted that deforestation accounts for 17% of carbon dioxide resulting from human activities.
The UN Summit on Climate in Cancun began on November 29 and ending on December 10.
The Conference is not in the spotlight, as most predict that participants will not be able to reach, rather than a binding agreement, nor even the adoption of some smaller sub-agreements on climate (eg the agreement on protection of areas of deforestation), as quarrels and interests as they appeared clearly in Copenhagen, remain at the forefront.

Honeybees are dying out worldwide

Four species are going extinct ...

Significant reduction of the population of bees recorded American scientists, sending alarm about the bug that is so important for agriculture.

Four species of bees, which until recently were considered crowded in the U.S., tend to disappear. Scientists have recorded a reduction in the population reaches 96% and reducing the area they cover by 87%.

As regards the bees produce honey, a pathogen involved, highlighted by the scientists, who found indications of inbreeding and caused the loss of their natural environment.

Rising Ocean Levels

Many times we hear that the sea level rises due to melting ice. It now seems that today, and what are the prospects?

Since 1900, global sea level has risen from 10 to 20 cm, of which the rise occurred only 3 cm between 1993 and 2003. From time to time appear everywhere some physiological changes in sea level. Thanks mostly to satellite measurements, experts have found that globally we are probably rising, albeit unevenly distributed on Earth, due to changes in sea currents and temperatures.

Scientists have not yet what caused the rise in sea level. Most of the link with global warming, which, inter alia contributes to melting glaciers and polar ice caps in general. The water from melting ice feeds the seas, gradually raising the level but also by reducing the salinity.

The calculations show that this situation will continue. According to the Intergovernmental Committee of the UN Climate Change (IPCC), the level of the oceans by the year 2100 will rise from 9 to 88 cm. How big will the increase depends mainly on greenhouse gases in the atmosphere. But even if the release is limited, there is no doubt that the rising level will continue to some extent after 2100.

If this estimate proves to be correct, millions of people in coastal areas with low altitude at risk of homelessness in the future from flooding. Large areas of Bangladesh will come under water, and will also be threatened cities such as Calcutta, London, New York, or even Greece.

Environment - Climate Change

The problem has been for many years seen by mankind. Historically the beginning of complete human intervention occurred before in two centuries since the industrial revolution. From that point on man consumed akatapafta natural resources (especially mineral) and in a totally uncontrolled way and rather competitive.

The result of this "evolution" Accumulator created environmental problems:

- Global (over) heat (global (over) warming)

The term global warming refers to the increase in average global temperature and ocean. According to the committee of the UN or global average temperature over the past century has risen 0.6 degrees C (± 0,2). The projections of the same committee at the end of this century is a much worse and likely further increase in temperature up to 5.8 degrees C.
global warming

The phenomenon of global warming has been most directly associated with the production of greenhouse gases from human activities.
The results of this growth has become considerably. (In Drama, we see a decent snowman decade). Poles of the earth already seen huge icebergs melt rapidly. The resultant sea level is expected to go up and make similar disasters.

Already using satellites (1992) has found that the average rise in sea level is 2.8 mm / year but held reservations about the reliability (resolution) measurements.

Other adverse events due to global warming include changes in rainfall rates, increased intensity and frequency of extreme weather events. Future expected in some areas, prolonged drought, and hygiene due to climate change.

- Greenhouse gases (greenhouse gases)

As mentioned greenhouse gases are primarily responsible for global warming. These gases absorb (trap) which essentially radiation at a rate to transmit to the earth, thereby warming the surface.

The major greenhouse gases are water vapor (H20), carbon dioxide (CO2), methane (CI4), sodium oxide (NO2) and ozone (O3).

Human activity is responsible for the increase in CO2, CI4, NO2, which are excreted rapidly in the atmosphere because of the dependence of the global economy on fossil fuels.
