Spain to bear between 3 and 6 degrees maximum temperature with respect to the reference values for 1961-1990 in 60 years, in particular for the period 2071-2100, according to the State Meteorological Agency (AEMET). For minimum temperature, however, the increase is between 2 º C and 5 º C. Balearic Islands, especially in peak values, as a result of the dampening effect of the oceans, you will experience temperatures below those of other autonomous communities.

The report has been submitted by the Secretary of State for Climate Change, Teresa Ribera, and AEMET president, Ricardo Garcia Herrera. This is the second phase of renovation of regionalized scenarios using new data from global models that form the basis of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) adopted in Valencia in 2007.

The abundance of phytoplankton or plant plankton, the first element of the food chain in the oceans, decreased markedly over the last century, as confirmed by a comprehensive study by Dalhousie University in Halifax (Canada).

The study, published by the journal Nature, finds that the reduction was approximately 1% per year since 1900, albeit with a higher trend since 1950, likely as a result of climate change and higher surface temperatures of ocean waters, say the authors.

Threat to the marine food chain

The phytoplankton, consisting of microscopic organisms that live suspended in water, is the staple food of zooplankton both as large mammals (cetaceans), numerous seabirds and the most fish. “They are the fuel of the marine ecosystem. Their fall affects the entire food chain and humans, “write Daniel Boyce, Marlon Lewis and Boris Worm, the three principal authors of the research. Read the rest of this entry »

Mengke Touming The glacier, one of the most beautiful in China and located in the northwestern province of Gansu, is melting the effect of climate change, reported the China Daily. ”

The Touming Mengke is the largest valley glacier in the Qilian Mountains in Sunan, but due to warming caused by greenhouse gases is suffering a reduction of six meters a year.

In the last five decades Touming Mengke, 10.1 km long and covers an area of 21.9 square kilometers, has been reduced by 300 meters.

Its maximum altitude is 5483 meters above sea level and the lowest is 4260 meters and is located in the valley Laohu, on the northern slope of the mountain Daxue, in the district of Subei. Read the rest of this entry »

So what makes an ordinary rain becomes acid rain? This happens when the acidity of rain falls in reaction to common air pollutants, primarily sulfur oxides and nitrogen oxides. So when the rain water comes into contact with human pollution of the atmosphere, forms sulfuric and nitric acids. So the rain becomes more acidic yet, with a pH below 3.

What causes it? Human pollutants such as noxious fumes long run factories and power plants as clean energy from coal, gas or petroleum products. Vehicles also emit harmful gases which contribute their grain to the general pollution.

Aquatic and terrestrial animals, trees and plants and even human infrastructure suffer the damaging effects of acid rain. It’s the fault of human beings, which emits nitrogen oxide and sulfur dioxide from factories, power plants, cars, etc.

Da effects of acid rain can become devastating, since the acidification of rivers, lakes and seas hamper aquatic life, to wear and death of plant life in forests.

To make matters worse, when acid rain falls to the ground, dragging the acidified water with natural fertilizers of the land, thus giving a total poverty, ending stressing the plants, since they remove their minerals and essential ions , thus producing more carnage.

statue degraded by acid rain But not only affects living things, but corrodes buildings and human infrastructure. For example statues and monuments made of marble or limestone, dissolve with each acid rain. Read the rest of this entry »

Increasing temperatures will lead to increased rainfall, but the effect is less clear on the storm. Extra-tropical storms partly depend on the temperature setting, which would weaken in the northern hemisphere as the polar regions warmer than the rest of the hemisphere, this would lead to low rates of melting ice and increased the cycle all over the world.

There are many potential impacts of global warming than hypothetically affect the environment and human life according to the theory of global warming. The main thing is the average temperature increased gradually.

From here, there are a number of different effects such as rising sea levels, changes in agricultural ecosystems, the spread of tropical diseases, the increasing intensity of natural phenomena. Some of this phenomenon will produce today, but it is difficult to determine a direct relationship to global warming.

One problem that seems to be given some advantage in the international opinion is whether or not we even have time to reverse the effects of greenhouse gas emissions are causing our global climate.

Here, climate change across the planet, except for natural disasters such as the fall of meteorites 365 million years ago caused the sudden change – they grow naturally a very gradual, ie they have to spend more than 100 lives a man to see only small changes.

Cycle of the earth have many years to someone who could barely understand, because we can not have a clear understanding of what they mean two or three million years, when we live only 100.
However, both by advances in technology and how they developed society, we have the ability to accelerate the process, change and even to overcome the planet’s remarkable ability to absorb and distribute these changes, adapt to their own time.

Planet since its inception has never failed to mutate from the time of the coldest ice, but the heating stage. However, this change is always a “slow” that no living creature must have sensed.

Tumbes develop a regional strategy to address climate change impacts

Tumbes.-Tumbes Regional Government in the north, forming a technical group will be responsible for developing strategies to address climate change impacts in this jurisdiction.

The team is led by the assistant manager of Civil and Environmental Defense, and consists of the Natural Resource Management, Regional Directorate of Production and Energy and Mining, and Port Captain Zorritos, among others.

The formation of this working group was formed during the meeting of the Regional Environmental Commission (RAC), which also created the Regional Technical Group on Water Resources.

Climate change poses the greatest threat to human health in the twenty-first century, says a joint article in the British medical journal The Lancet and scientists from University College London (UCL). Global warming brings with different patterns of infection and new ranges of insect-borne diseases. In addition, the report will cause more deaths from heat waves. Also at risk is the supply of clean water and food, which could result in as many cases of malnutrition and diarrheal diseases.

Furthermore, man is more prone to extreme weather events like hurricanes. “Climate change is a health issue that affects billions of people. It is not just an environmental issue, which revolves around the polar bear or logging, “said professor
UCL Anthony Costello.

The effects will be felt worldwide. And not in the distant future but in the course of our lives and the lives of our children. Costello noted that scientists are pressing for quick action against the emission of greenhouse gases and deforestation of tropical forests. He has also argued that health authorities, politicians and scientists must work closely to limit the negative effects of climate change on health.
