Global Warming 101

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. This page has no sub-navigation. Skip to page content. What are greenhouse gases and how do they affect the climate? Most scientists believe that water vapor produced directly by human activity contributes very little to the amount of water vapor in the atmosphere.

The U. Ozone is technically a greenhouse gas because it has an effect on global temperature. However, at higher elevations in the atmosphere stratosphere , where it occurs naturally, ozone is needed to block harmful ultraviolet light. At lower elevations of the atmosphere troposphere , ozone is harmful to human health and is a pollutant regulated independently of its warming effects. How do I convert between short tons and metric tons? How much carbon dioxide is produced from U.

How much carbon dioxide is produced per kilowatthour of U. How much carbon dioxide is produced when different fuels are burned? Why do carbon dioxide emissions weigh more than the original fuel? How much of U. Is ozone a greenhouse gas? What are U. What are the energy-related carbon dioxide emissions from fossil fuels for the United States and the world? What are the greenhouse gas and air pollutant emissions factors for fuels and electricity?

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.

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.

Через тридцать секунд она уже сидела за его столом и изучала отчет шифровалки. - Видишь? - спросил Бринкерхофф, наклоняясь над ней и показывая цифру.  - Это СЦР. Миллиард долларов.

What is the difference between global warming and climate change?

Интересно, почему Стратмор его до сих пор не отключил.
