WHAT DOES THE SCIENCE

80% REDUCE POLLUTION

To achieve the goal of limiting the increase in global temperatures to 2 degrees, agreement taken by the international community, it involves scientists say reducing emissions of gases that cause the greenhouse effect between 41 and 72% compared to 2010 by mid-century. At the rate of current emissions sobrepasaríamos the limit of two degrees by 2050, figure that science would lead to a concentration of 450 ppm (parts per million) of CO2 in the atmosphere, now we are at 400 ppm, growing at a rate of 1.5 ppm per year.

This is really worrying because despite the supposed global efforts to reduce them and the global financial crisis, global emissions have increased to unprecedented levels in the last decade (2000-2010) more than any of the previous three decades, mainly due to increased use of coal as an energy source.

The scientific diagnosis and prescriptions are clear: first stop broadcasting, decarbonising energy production, abandoning coal, fossil fuels and a resolutely bet on renewable, and secondly capturing the CO2 that is already in the atmosphere, slowing deforestation, promoting reforestation, and finally invest in a wide range of technologies to be more efficient with the use of energy, and capture and storage of CO2.

IPCC

Intergovernmental Panel on Climate Change

Intergovernmental Panel on Climate Change (IPCC) created in 1988 to warn of this problem, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP).

The role of the IPCC is to analyze in a comprehensive, objective, open and transparent, relevant scientific, technical and socioeconomic information to understand the scientific basis of risk of climate change caused by human activities, its potential impacts and opportunities adaptation and mitigation.

The IPCC does not conduct research or control own climate-related data or other relevant parameters, but bases its assessment mainly on scientific and technical literature and published peer reviewed previously.

One of the main activities of the IPCC is to make a periodic assessment of knowledge about climate change, through special reports and technical papers. The main reports are translated into Castilian:

1st Report IPCC_1990. Download
WWDR2 IPCC_1995. Download
Report 3 IPCC_ 2001. Download
4th Report IPCC_2007. Download
Renewable energy sources and climatico_2011 change mitigation. Download
Risk management of extreme weather events and disasters to improve adaptation to change climatico_2012. Download

The 5th Report is divided into 3 installments over the ratification of the report:

Physical bases. September 2013. Download – Guide summary-OECC
Impacts, Adaptation and Vulnerability. March 2014 Download
Climate change mitigation. April 2014 Download (English)
Conclusions and synthesis. November 2014. Download (English)
