Understanding what causes global warming

But ammonia like other refrigerant gases such as sulfur dioxide and methyl chloride had serious problems. Just like the year GWP is based on the energy absorbed by a gas over years, the year GWP is based on the energy absorbed over 20 years.

Understanding Global Warming Potentials

But, many powerful industry interests have hindered action and have, largely through surrogatesspread dangerous myths about climate change. Nobody wants to be caught unaware and unprepared. In addition, other greenhouse gases not normally found in nature are being added to the atmosphere.

Over time, these and other adaptation measures will save lives, money, and valuable resources. Do not confuse the two. Yes, human activities exert a cooling influence on Earth in several ways.

Global warming

The net result is to intensify Earth's greenhouse effect, causing Earth's surface to warm. Small increases in ocean temperature severely stress corals and cause them to expel the symbiotic algae that nourish them and give them their vibrant colors.

Additionally, there are unresolved legal and ethical issues surrounding geo-engineering. Though these important greenhouse gases occur naturally in the atmosphere in varying concentrations, human activities are directly and indirectly increasing their abundance.

These changes can be a threat to humans as noted above in answers to previous questions.

What Causes Global Warming?

This threat includes both the gradual upward creep of sea level and periodic, catastrophic ocean surges associated with land-falling cyclones. Children, the elderly, the sick, the poor, and nature are especially vulnerable.

Water availability will be impacted in drier agricultural areas that need irrigation. What is Global Warming? Walking to school is also great exercise Related Stories.

Thus, there was a slight increase in the amount of sunlight shining where most of our planet's landmass is located, which was just enough to nudge our world in a warming direction. It is also believed that sea levels have risen up to about 19cm globally, with lots of glaciers melting in addition.

For example, the huge volcanic eruption of Mount Pinatubo resulted in a short cooling effect. For example, a doctor may have a hard time determining exactly when a particular overweight, middle-aged person who smokes cigarettes is going to die.

Scientists Agree: Global Warming is Happening and Humans are the Primary Cause

However, changes in the intensity or frequency of extremes may be influenced by human-caused climate change. Business leaders can evolve their business models to pursue "win-win" strategies that allow them to stay profitable while improving their energy efficiency, reducing their carbon emissions, and reducing their, and their customers', risks to climate-related impacts.

Hopefully in the near future, all countries across the globe will come together to support this necessary pact. Weather forecasters look at initial conditions and then make short-term deterministic predictions about future events from minutes to days, to less than 2 weeks.Scientists worldwide agree that global warming is happening, and that human activity causes it.

Image: IPCC Assesment Report 5 Cover The IPCC Fifth Assessment Report (AR5), written by a panel of hundreds of climate experts and scientists from member countries of the World Meteorological Organization the United Nations Environmental Programme. Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.

Multiple lines of scientific evidence show that the climate system is warming. Global warming (as well as global cooling) refers specifically to any change in the global average surface temperature.

Do not confuse the two. Climate change is a change of the composition of global atmosphere, observed over a period of time, and in comparison to other time periods, as a direct or indirect result of human activity.

We 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. Global warming is opening doors for the development of new types of fuels, leading the shift to reliable energy sources, and creating a vision of a greener tomorrow.

Understanding Greenhouse Gases Planet Earth is warm enough to sustain life thanks to gases in the planet’s atmosphere that hold heat. The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases.

Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO 2).
