Causes of climate change

The effects of climate change span the physical environment , ecosystems and human societies. It also includes the economic and social changes which stem from living in a warmer world. Human-caused climate change is one of the threats to sustainability. Many physical impacts of climate change are already visible, including extreme weather events, glacier retreat , [7] changes in the timing of seasonal events e. Climate change has already impacted ecosystems and humans.

What is global warming? What causes global warming? What is climate change? Is it different from global warming? What is a climate change impact? What does global warming have to do with severe weather, like storms, heat waves, droughts, and hurricanes? If global warming is real, why is it so cold and snowy this winter?

Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed vast areas of land from forests to farmland. Burning fossil fuels produces carbon dioxide, a greenhouse gas. The greenhouse effect makes the earth warmer, just as a greenhouse is warmer than its surroundings. It stays in the atmosphere for a very long time.

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.

Greenhouse Gases: Causes, Sources and Environmental Effects

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. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter.

Global Warming / Climate Change Frequently Asked Questions (FAQ)

Behind the struggle to address global warming and climate change lies the increase in greenhouse gases in our atmosphere. A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. Global warming isn't a new concept in science. The basics of the phenomenon were worked out well over a century ago by Svante Arrhenius in His paper, published in the Philosophical Magazine and Journal of Science, was the first to quantify the contribution of carbon dioxide to what scientists now call the "greenhouse effect. The greenhouse effect occurs because the sun bombards Earth with enormous amounts of radiation, which strike Earth's atmosphere in the form of visible light, plus ultraviolet UV , infrared IR and other types of radiation that are invisible to the human eye.

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases i. Part of this radiation is directed towards the surface, thus warming it. The temperature rises until the intensity of upward radiation from the surface, thus cooling it, balances the downward flow of energy. Earth's natural greenhouse effect is critical to supporting life, and initially was a precursor to life moving out of the ocean onto land. Human activities, mainly the burning of fossil fuels and clearcutting of forests, have increased the greenhouse effect and caused global warming.

Solar radiation and the "greenhouse effect"

 Это нацарапал мой дружок… ужасно глупо, правда. Беккер не мог выдавить ни слова. Проваливай и умри. Он не верил своим глазам. Немец не хотел его оскорбить, он пытался помочь.

Что бы ни произошло на самом деле, мы все равно выглядим виновными. Яд, фальсифицированные результаты вскрытия и так далее.  - Стратмор выдержал паузу.  - Какой была твоя первая реакция, когда я сообщил тебе о смерти Танкадо. Сьюзан нахмурилась.

ME TOO, что означало: Я. Беккер расхохотался. Он дожил до тридцати пяти лет, а сердце у него прыгало, как у влюбленного мальчишки. Никогда еще его не влекло ни к одной женщине. Изящные европейские черты лица и карие глаза делали Сьюзан похожей на модель, рекламирующую косметику Эсте Лаудер. Худоба и неловкость подростка бесследно исчезли.

Все звонки принимались единственным оператором на двенадцатиканальный терминал Коренсо-2000. Телефонистка, державшая трубку у уха, мгновенно поднялась и поклонилась, увидев босса. - Садитесь! - рявкнул Нуматака.

Сьюзан чувствовала, как кабина набирает скорость, двигаясь в сторону главного здания АНБ. Наконец она остановилась, и дверь открылась. Покашливая, Сьюзан неуверенно шагнула в темный коридор с цементными стенами.

Очевидно, он ошибался. Девушка обвила его руками. - Это лето было такое ужасное, - говорила она, чуть не плача.  - Я вам так признательна. Я так хочу выбраться отсюда.

 Да будет.  - Хейл вроде бы затрубил отбой.  - Теперь это не имеет значения.

 Данные? - спросил Бринкерхофф.  - Какие такие данные. Танкадо отдал кольцо. Вот и все доказательства.
