Climate change includes both global warming driven by human emissions of greenhouse gases , and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change , since the midth century humans have had unprecedented impact on Earth's climate system and caused change on a global scale. Temperature rise on land is about twice the global average increase, leading to desert expansion and more common heat waves and wildfires. It further magnifies risks of flooding, infectious diseases and extreme heat, with the World Health Organization calling climate change the greatest threat to global health in the 21st century.
The atmosphere is a dynamic fluid that is continually in motion. Both its physical properties and its rate and direction of motion are influenced by a variety of factors, including solar radiation , the geographic position of continents , ocean currents , the location and orientation of mountain ranges, atmospheric chemistry , and vegetation growing on the land surface. All these factors change through time. Some factors, such as the distribution of heat within the oceans , atmospheric chemistry, and surface vegetation, change at very short timescales. Others, such as the position of continents and the location and height of mountain ranges, change over very long timescales.
In the following viewpoint, Canadell argues that recent efforts to improve energy efficiency and increase the use of clean energy have contributed to a stalling in fossil fuel emissions. However, Canadell contends that governments will need to increase their efforts to meet the climate goals established in the Paris Agreement. He compares the successes and shortcomings of China, the United States, India, Australia, and the European Union in reducing emissions. He examines the practice of storing carbon dioxide underground through carbon capture and storage CCS and concludes that thousands of CCS facilities will be necessary to meet climate goals. In the following viewpoint, Thomas argues that politicians use the issue of climate change as an excuse for the government to interfere in the lives of private citizens. Noting that some climate predictions have overestimated the impact of global warming, the author disputes the widely held belief that global temperatures are rising as a result of human activity.
Human action is causing an increase in global temperature. For that reason, the greenhouse effect, far from being our great ally as was the case in the past, is now a risk to our survival. The flooding of coastal cities, the desertification of fertile areas, the melting of glacial masses and the proliferation of devastating hurricanes are just some of the main consequences. Global warming is having a profound impact on the processes of soil degradation and is contributing to the desertification of the most arid areas on the planet. The increase in the global temperature of the planet produces a rise in the level of the sea, which will cause the disappearance of islands and coastal cities. The greenhouse effect is a natural phenomenon and is beneficial for us.
Global warming , the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Increases in greenhouse gases —i. Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately. Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy flooding , and wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure.
Jump to navigation. And yes, it's really happening. Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. And scientists say that unless we curb global-warming emissions, average U.
During the course of global warming, the energy balance and thus the temperature of the earth change, due to the increased concentration of greenhouse gases, which has a significant impact on humans and the environment. It is not scientifically possible to assign individual weather events to the current climate change, however, it can be statistically proven that global warming will increase the probability of extreme weather events. The indirect consequences of climate change, which directly affect us humans and our environment, include:.

Неужели все это был сон. Сьюзан повернулась к тумбочке. На ней стояли пустая бутылка из-под шампанского, два бокала… и лежала записка. Протерев глаза, она натянула на плечи одеяло и прочла: Моя драгоценная Сьюзан. Я люблю .
- Танкадо потребовал ТРАНСТЕКСТ. - ТРАНСТЕКСТ. - Да. Он потребовал, чтобы я публично, перед всем миром, рассказал о том, что у нас есть ТРАНСТЕКСТ. Он сказал, что, если мы признаем, что можем читать электронную почту граждан, он уничтожит Цифровую крепость.
- Если только… Сьюзан хотела что-то сказать, но поняла, что сейчас-то Стратмор и взорвет бомбу. Если только -. - Если только компьютер понимает, взломал он шифр или .
