Climate change: a major global threat.

The climate change, that is, the change of the global climate and in particular the changes in meteorological conditions that extend on a large time scale, is a major global existential threat. The greenhouse effect causes the increase of temperature of the planet primarily due to the tremendous increase in carbon dioxide, which has increased by 35 percent since the beginning of the industrial revolution. And of course the lion's share in pollution of the atmosphere with 50 percent of all carbon dioxide have Europe and North America. All other countries together are responsible for the other half, while the poorest countries are the least responsible. However, the people who live in these countries it is they who will suffer more strongly of the consequences.

The causes of climate change are mainly identified in combustion of fossil fuels (coal, oil, gasoline, natural gas, etc.) which account for 50 percent of total emissions, in the production and use of synthetic chemicals, in disaster of forest areas, which contributes to the production of additional gases in the atmosphere and of course to the greenhouse effect by 15 percent and in conventional agriculture and livestock farming, which account for 15 percent of emissions.

The expert scientists knock the danger bell and warn that if there is no urgent global coordinated action by political leaders, governments, industries and citizens around the world, the temperature of the planet is likely to rise above 2AdegC relative to pre-industrial levels by 2060 and the increase could even reach 5AdegC by the end of the twenty-first century, fact that will make the lives of future generations problematic.

Such an increase in the temperature of our planet will have a devastating impact on nature, bringing about irreversible changes in many ecosystems and consequent loss of biodiversity, that is, all living organisms and species that make up life on the planet, that is, animals, birds, fish and plants (fauna and flora). Many species are expected to disappear from areas that will be directly and severely affected by climate change.

Today, compared to 1850 - from when recording data began - a temperature increase of 1.1AdegC is observed. So, it is vital importance, the increase not to exceed 1.5AdegC, because as scientists estimate, beyond this crucial point there will be no way back.

The climate change, however, is due to human activities, is a tangible ominous reality and is already adversely...
