Global Warming

The main cause of global warming

The main cause of global warmingCarbon Monoxide (CO): A colorless, odorless gas. When inhaled, the molecules enter the bloodstream, where they inhibit the distribution of oxygen. Low concentrations cause dizziness, headache and fatigue, while higher concentrations can be fatal.

Carbon monoxide results from incomplete combustion of carbon-based fuels such as gasoline, oil and wood, and natural and synthetic products, such as cigarette smoke. It is found in high concentrations in enclosed spaces such as garages and tunnels with poor ventilation, and even in congested traffic roads.

Carbon dioxide (CO2) gas is the main cause of global warming. It originates from the combustion of coal, oil and natural gas. In liquid or solid sunburn, frostbite, and blindness. Inhalation is toxic if found in high concentrations, can cause increased breathing rate, unconsciousness and even death.

Chlorofluorocarbons (CFCs) are chemicals that are used in large quantities in industry, refrigeration and air conditioning in the development of consumer goods. When released into the atmosphere, rise into the stratosphere. Once there, the CFC chemical reactions that lead to the reduction of the ozone layer that protects Earth’s surface from sunlight. The reduction of emissions of CFCs and the suspension of production of chemicals that destroy the ozone layer are fundamental steps for the preservation of the stratosphere.

Hazardous Air Pollutants (HAP): These are chemicals that affect health and the environment. The mass emissions, as the disaster that took place in a chemicals factory in Bhopal, India, can cause cancer, birth defects, nervous system disorders and even death. Read the rest of this entry »

Prevent damage from global warming

Prevent damage from global warmingSoftware capable of identifying and assessing trends in climate change because of global climate change was created by members of the Center for Environmental Geography Research (CIGA) of the National Autonomous University of Mexico.

Software called MOCLIC (Monitoring Climate Change) runs through data obtained by meteorological stations, and can identify changing trends in extreme temperatures (maximum and minimum) caused by climate change in a specific community.

Dr. Francisco Bautista Zúñiga, CIGA researcher on campus Morelia, explained that the program provides local weather data are commonly captured on paper and on the computer to analyze and evaluate the variability and climate change. The data were plotted to better understand the state of the weather.

With MOCLIC be answered what are the trends of climate change if temperatures are expected downstream or upstream, of what magnitude, months or years in which the change occurs and where it occurs.

The system allows the generation of indices and indicators for the study of climate variability and change of weather elements, as well as time series analysis with an unscientific leguaje for the user to understand it better.

In addition, the program is possible to calculate the moisture, dryness, rain or concentration erosivity of rainfall, and from the data obtained may prevent the impact of flooding in towns, detached from earth or holes in the soil and subsoil.

The objective is to analyze the trend of climate change for marginalized communities prevent sudden changes in temperature, to avoid damaging economic activities of people – like the loss of livestock and crops – and in health children and seniors primarily.

The first tests of the software took place in the city of Apatzingan, Michoacan, and in the community of Peto, Yucatan, where temperatures were detected up to 40 degrees Celsius can affect the region’s economic activities and health people.

Bautista stressed that MOCLIC Zuniga should be in all the offices of the National Water Commission and the National Meteorological System, as in the local departments of health and environment so that correct decisions are made about the damages of climate change .

Bautista Zúñiga said that thanks to MOCLIC established collaboration agreements with software engineers from the Instituto Tecnológico Superior de Tacambaro, Michoacán, particularly with the engineer Oscar Alvarez Arriaga.

Global average temperature of the sea

Global average temperature of the seaThe climate system is unequivocal, as is already clear the observed increase in global average air temperature and ocean, the widespread melting of snow and ice and rising global average sea level.

For the IPCC, the term “climate change” denotes a change in climate state identification cable (for example, by statistical analysis) following a change in the mean and / or the variability of its properties, and persists for an extended period, typically decades or encryption over longer periods. Denotes any change in climate over time, whether due to natural variability whether due to human activity.

Most of the observed increase in global average temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic GHG concentrations.

This meaning differs from that used in the United Nations Framework Convention on Climate Change (UNFCCC), which describes climate change as a change of climate attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.

Global Warming: How is it Calculated its Impact?

Global warming: how is it calculated its impact?

The fact that a collapse of civilization be no possibility unlikely, and therefore fit that in the not too distant future, instead of arguing about the feet of beach lost in the tourist areas, or about the costs marginal increase in elderly deaths from heat waves, we are estimating how many small groups of hunter-gatherers, they managed to survive in the steppes of a Europe devastated and impoverished, the fact that such a collapse is possible should be sufficient to promote policies ambitious to fight climate change. We can not continue to bury our heads in the sand and postponing the effective action: time is running out.

Some of the major disagreements have to do with the procedures used by economic analysts in translating biophysical to socioeconomic impacts. Regarding the problem of vast implications of global warming, reappear difficult scientific issues that have fueled heated debates between the orthodox economic establishment on the one hand, and secondly the new prospects opened up by the green economy (and in part by the environmental economics) over the past decades. A way of targeting the underlying problem is that suggested by Francisco Javier Rubio de Urquia: “While we continue using models limited, almost exclusively, the cost analysis of the quantitative level, we are not able to have a more comprehensive view that allows us to properly assess costs and qualitative benefits, for example, derived from the burden borne by the nature and the services it provides. The mere thought that technological progress and market forces are sufficient to alleviate environmental problems under pricing evidence, if not contempt, which has been nature. Believe that we act as if we self-sufficient and, thanks to technology, we are able to cater for all goods and services it provides, and which are vital to our existence, only reflects a high dose of arrogance and over not less than ignorance.”

Global Campaign for Climate Justice Demand

Global Campaign for Climate Justice Demand

International negotiations on climate change is one of the areas that require concerted efforts. Several organizations have worked collectively in a call for a global campaign for climate justice, from now on to Durban and beyond. We invite everyone to join this global campaign and to sign the call as an expression of their commitment.

We are movements and organizations engaged in numerous struggles for a new world, a world in which the needs, interests, rights and aspirations of all peoples have priority over the profit of corporations and the excesses of the elite. In the year ahead, our solidarity and collective action are extremely crucial. Climate change is already devastating impacts globally and is accelerating. The margin that we have to prevent rupture occurring in critical situations and to stop climate catastrophe is shrinking rapidly.

Climate change is much more than a multiplication of the sufferings of people already overwhelmed by the injustice of hunger, dispossession and violation of human rights. It is a crisis also threatens to wipe out vast populations and profoundly change life on Earth. We must act with clarity, cohesion and courage if we are to stabilize the climate system on the planet and ensure a just and sustainable world.

Like other global crises, climate change arises mainly from economic and social structures historically unequal, practices and policies pursued by rich countries, industrialized, and production and consumption systems that sacrifice the needs of most interest in terms of a minority. Affected peoples of the world have very little responsibility for the climate crisis, yet suffer its worst effects and lack the means to respond to it.
