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.

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.

The major greenhouse gases emitted by the United States as a result of human activity, and their percentage share of total U. There are other greenhouse gases that are not counted in United States or international greenhouse gas inventories:. This greenhouse effect traps radiation from the sun and warms the planet's surface. As concentrations of these gases increase, more warming occurs than would happen naturally. Source: U.

In simplest terms, "greenhouse gases" let sunlight through to the earth's surface while trapping "outbound" radiation. This alters the radiative balance of the earth see Figure A. The greenhouse gases in the atmosphere act in much the same way as the glass panels of a greenhouse, which allow sunlight through and trap heat inside. The panel refers to warming due to increased atmospheric concentrations of greenhouse gases as "greenhouse warming.

Global Warming 101

Glaciers are melting , sea levels are rising, cloud forests are dying , and wildlife is scrambling to keep pace. It has become clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than at any time in the last , years. We often call the result global warming, but it is causing a set of changes to the Earth's climate, or long-term weather patterns, that varies from place to place. Climate change encompasses not only rising average temperatures but also extreme weather events , shifting wildlife populations and habitats, rising seas , and a range of other impacts. All of those changes are emerging as humans continue to add heat-trapping greenhouse gases to the atmosphere, changing the rhythms of climate that all living things have come to rely on. What will we do—what can we do—to slow this human-caused warming?

By Agnieszka Biskup. May 7, at pm. As they hit the soil and surface waters, those rays release much of their energy as heat. Some of the heat then radiates back out into space. However, certain gases in our atmosphere, such as carbon dioxide, methane and water vapor, work like a blanket to retain much of that heat. This helps to warm our atmosphere. But there can be too much of a good thing.

What is the difference between global warming and climate change?

Greenhouse gases from human activities are the most significant driver of observed climate change since the mid th century. As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes. These changes have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations.

То, что она увидела, казалось лишенным всякого смысла. 22: РУЧНОЕ ОТКЛЮЧЕНИЕ ГЛАВА 35 Беккер в шоке смотрел на Росио. - Вы продали кольцо.

Мы говорим о математике, а не об истории. Соши замолчала. - Полезный груз? - предложил Бринкерхофф.  - Количество жертв. Ущерб в долларах. - Нам нужна точная цифра, - напомнила Сьюзан.  - Оценки ущерба всюду приводятся разные.

Беккер молил Бога, чтобы это оказалось неправдой. - Рего… Но… Она пожала плечами и произнесла по-испански: - Девушке возле парка. Беккер почувствовал, что у него подкашиваются ноги.

 - Я все объясню. Она попыталась высвободиться. Коммандер не отпускал. Она попробовала закричать, но голос ей не повиновался. Ей хотелось убежать, но сильные руки тянули ее. - Я люблю тебя, - шептал коммандер.

Беккер достал блокнот. - Итак, начнем с утра. Расскажите мне, что произошло. Старик вздохнул. - Очень печальная история. Одному несчастному азиату стало плохо.

 Мы выстрелили в него новым Джей-23, это нервно-паралитическое вещество продолжительного действия. Конечно, это чертовски болезненно, но нам нужно было его остановить. - Не волнуйтесь, мадам, - заверил второй агент.  - С ним все будет в порядке. Дэвид Беккер смотрел на экран прямо перед. У него кружилась голова, и он едва отдавал себе отчет в происходящем. На экране он видел комнату, в которой царил хаос.
