Not taking into account the month of June was cooler than normal, July, August and September so far has become the warmest period since 1970, according to the Meteorological Agency (AEMET). “Temperatures are recorded to confirm the gradual warming” related to climate change, has clarified the Agency spokesman, Angel Rivera.

An analysis of the June-August quarter, average temperatures were recorded 1.4 degrees above average, making it the eighth warmest summer quarter 1971. Five of the eight most sweltering summer periods have occurred in the XXI century, which again confirms the trend towards global warming, according to AEMET.

The quarter has been extremely warm in Extremadura and Western Andalusia, Read the rest of this entry »

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 »

It is true that human beings require a number of minerals to meet some of their needs, basic or not. But it is also true that excessive consumption of some humans are destroying their livelihoods and the environment on the other side of humanity, who live in areas affected by mining.

Because of its impacts, mining is one activity that should be tightly controlled at all stages, from exploration and exploitation for the transportation, processing and consumption. In many cases, the only means strict control restrictions.

To claim that the mining company itself controlled is more than naive: it makes sense. Even the control of the government are not sufficient, considering the economic and political power that has proven mining company on them. It should empower all citizens to participate directly in this control.

Between 19 and 23 kilometers above the earth in the stratosphere, a thin layer of gas, the ozone layer, surrounds and protects the earth from harmful solar rays.

Ozone is produced by the effect of sunlight on oxygen and is the only substance in the atmosphere that can absorb harmful ultraviolet radiation (UV-B) from the sun. This thin layer makes life possible on Earth.

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.
