Earth’s climate is very difficult to predict, because there are many factors to consider: rain, sunshine, wind, temperature … So you can not specify what the effects would cause global warming. But it turns out, can be very severe climate change.
The first consequence, it is possible, is the improvement of drought: in some places less rainfall. On the other, the rain will increase, causing flooding.

Warmer atmosphere can cause the ice near the poles are melting. The amount of water would raise the sea level. Increased by only 60 cm would inundate fertile soil in Bangladesh, India, among them hundreds of thousands of people depend on for food. tropical storms may occur more frequently.

Emissions of carbon dioxide have surged 41% from 1990 to the present. This is an alarming percentage, if we consider that is a global benchmark. Carbon dioxide (CO2) pollution is one of the largest and most important greenhouse gas. The Earth begins to suffer the consequences and accelerates global warming.

These data are the result of a report prepared minuscioso the International Global Carbon Project (GPC). Corinne Le Quere, professor at the University of East Anglia in the UK is the Coordinator in charge of the investigation. As stated by the teacher: “If this continues, we will increase the temperatures of 5 or 6 degrees by 2100.

In the report prepared Global Carbon Project (GPC) has analyzed the ability of the Earth to meet this increase in emissions. Until recently, much of the CO2 caused by human activity ended in the oceans or be absorbed by vegetation. Undoubtedly, this was positive because the carbon dioxide did not reach the atmosphere and prevented the enhanced greenhouse effect. Read the rest of this entry »

The Earth’s climate is very difficult to predict, because there are many factors to take into account: rain, sunshine, wind, temperature … So you can not define exactly what effects will result in Global Warming. But apparently, climate change could be very severe.

A first consequence, very likely, is the increase of drought: in some places the rainfall decrease. In others, the rain will increase, causing flooding.

A warmer atmosphere could cause the ice near the poles are melting. The resulting amount of water would raise the sea level. An increase of only 60 feet could inundate the fertile lands of Bangladesh, India, from which additional hundreds of thousands of people to obtain food. Tropical storms may occur more frequently.

Scientists have spent decades figuring out what is causing global warming. They have observed the natural cycles and events that are known to influence climate. But the amount and pattern of warming that has been measured can not be explained by these factors alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHG) emitted by humans.

To bring all this information, the United Nations formed a group of scientists called the International Panel on Climate Change, or IPCC. The IPCC meets every few years to review the latest scientific findings and write a report summarizing what is known about global warming. Each report represents a consensus or agreement, among hundreds of prominent scientists.

One of the first things scientists learned is that there are several greenhouse gases responsible for warming, and humans are issued in a variety of ways. Most are from burning fossil fuels in cars, factories and electricity production. The gas responsible for most of the warming is carbon dioxide, also called CO2. Read the rest of this entry »

The climate has always varied, the problem of climate change is that in the last century the pace of these changes are abnormally accelerated to such an extent that affects and planetary life. In seeking the cause of this acceleration, scientists found that a direct relationship between global warming or climate change and increasing emissions of greenhouse gases (GHGs), caused primarily by industrialized societies.

A phenomenon of concern to the world: global warming and its direct impact, climate change, which occupies much of the efforts of the international scientific community to study and control it, because, they say, threatens the future of humanity.

Why so worried? Leading scientists agree that the increased concentration of greenhouse gases in Earth’s atmosphere is causing changes in climate. They also agree that emissions of greenhouse gases (GHGs) have been very intense since the Industrial Revolution, after which time the action of man over nature became intense.
