Global Warming: Mitigation Strategies and Solutions

Global Warming: Mitigation Strategies and Solutions

Introduction

The climate system is unequivocal, as is clear from the observed increase in global average air temperature and the ocean, 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 their properties, and persists for an extended period, typically decades or encryption over longer periods. Denotes any change in climate over time, either due to natural variability or is a result of human activity. Most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to increases in anthropogenic greenhouse gas 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.

These humorous verses sang once young students, hardly suggesting that at the beginning of the XXI century. Global climate change is found to be the greatest danger to any ever face by humanity. Today this problem is all the more possessed by the world's attention. About her increasingly resemble the media and politicians say. She is dedicating research and feature films. For its efforts to deepen and spread knowledge about climate generated by mankind awarded the Nobel Peace Prize in 2007 - its divided the UN Intergovernmental Panel, long-term studies which have been reflected in a series of fundamental research reports, and an American, Al Gore, former U.S. vice-president, a champion environmental protection, the creator of the famous documentary "An Inconvenient Truth" - a passionate warning about the threat of global warming.

Positive or negative human impacts

To date, the global scientific community will have irrefutable proof of the secular trend of global warming, which serves as an indicator of climate change on Earth. Over the past century surface temperature of the atmosphere has increased by 0.74 º C. Average temperatures in the Northern Hemisphere during the second half of the twentieth century; it was as higher than in any 50-year period in the last 500 years, and probably the highest in the last 1300 years. Since the phenomenon of global warming agreement, such evidenced by the huge array of empirical material phenomena such as rising sea levels, melting glaciers and polar ice sheets (particularly in the Arctic), reducing the snow-covered ice and the Earth's surface area, increasing rainfall in some regions (East North and South America, Northern Europe, North and Central Asia) and a decrease in others, the expansion of arid zones (Africa, parts of South Asia), more frequent tropical cyclones in the North Atlantic, etc., Global warming and climate change in one way or another bearing on the state of many natural ecosystems, ...
