Warmest years since 1880

Our planet is alive

The Earth is a living planet, now this "macro body" is feverish and humanity that dwells in panic every flood, storm, tsunami and another earthquake.
And yet we continue, year after year, to help increase the temperature inside the greenhouse that protects us for millions of years.
The 9 warmest years since 1880, are between 2000 and 2012, according to NASA scientists.
The medium-term forecasts are alarmist, a warming of 1.4 to 5.8 degrees Celsius is foreseen by the end of the 21st century. This will be the largest increase in Earth's temperature since 10,000 years.
Between the ice age, 20,000 years ago and the hottest period, there are 7000 years, there were only 7 ° C difference. If the temperature of the Earth increases by a century of 5.8 degrees Celsius as advertised, the living world will have to adapt very quickly. The first consequences of global warming are already visible. Indeed we see every day as glaciers retreat, floods are more devastating, that periods of drought return more frequently, the Arctic sea ice decreases... However, the scale of humanity is so small compared to the geologically it is pretentious to believe that warming of this magnitude has never happened in the past. There are certainly many factors that can influence the Earth's climate and we are far from knowing all. However, many analyzes show that our involvement in global warming temperatures on the surface of the Earth. We are aware of this and it is likely, despite "all our efforts," we will not be able to change the temperature curve started. The global ecological footprint, created in the 1990s by MM. Mathis Wackernagel and William Rees, two researchers from the University of British Columbia in Vancouver, is the pressure exerted by humanity over nature.

 

It assesses the productive area required for a population to meet its consumption of resources and needs to absorb waste.
Since 2007 this demand exceeds the capacity limits of ecosystem restoration.
The human economy is in ecological overshoot.
The overall ecological footprint of humanity has increased by 50% between 1970 and 1997, an increase of approximately 1.5% per year.
The increasing proliferation of the human species on the planet can cause a real environmental collapse as humanity uses water faster than it is recharged into the ground. it cut forests faster than they can regenerate, emits CO2 into the atmosphere faster than it can absorb.
Human societies are still animal societies, they exploit until exhaustion total resources available to them. Sooner or later, we must reorganize and adapt as we needed every time the "Nature".

The 10 warmest years

    

The temperature at the surface of the globe in 2012 was higher by 0.55 ° C (1 ° F), compared to the average temperatures from 1951 to 1980 (source data from the Goddard Institute for Space Studies published in January 2013). The temperature of the planet varies from year to year, so quickly that it is possible to represent a color map, this increase as a sensitive indicator of the frequency of climate anomalies. Global average temperature over 5 years, has stagnated since ten years, which we interpret as a combination of natural variables and a slowdown in the growth rate of climate forcing. The analysis reveals that in 2012 NASA had almost the same global temperature in 2011, well below the peak reached in 2010. These short-term global fluctuations are mainly associated with natural oscillations of surface temperatures of the tropical Pacific sea. But 2012 is nominally the ninth warmest year since 1880. We reject more CO2 and other waste and that odorous likely to continue because the energy needs of the world population increases, with demographics. We note at once that nature unleashes more violently and at the same time that the living world is struggling to adapt to these climatic fluctuations, leaving the weakest. Everything happens as if our "macro body" Earth is currently undergoing a small "fever".
Just as in warm-blooded animals, fever is a reaction of defense against internal aggression which requires him to activate certain immune mechanisms to regain his balance.
Let's just hope that these mechanisms are not fighting man as if it were an infectious agent abroad. Humanity now advised has to prove it is a constituent own and not alien from the planet Earth.

Nota: The 10 warmest years have all been recorded since 1998.
The warming trend in the long term, including warming steadily since the 1970s, has been definitively associated with greenhouse gas anthropogenic become important in the early 20th century.

 

Image: The analysis of the NASA surface temperature of the Earth shows that 2012 is the ninth warmest year since 1880. This is from 1880, as global temperature data are recorded with sufficient weather stations around the world. Scientists at the Goddard Institute compared the average temperature of each year, the average from 1951 to 1980. This 30-year period provides a basis for measuring global warming due to increasing atmospheric levels of greenhouse gas emissions.
