Three examples of evidence of global warming:
1. The ice sheets at the poles (north and south) are melting and retreating, which can only happen when the temperature is above the freezing point of the ice.
2. The air temperature today is, on average, warmer than the historical average from the late 1800s through about 1950.
3. The weather patterns are becoming more extreme, with more powerful and unusual storms coming earlier or later in the year than what is historically typical. The summers are tending to be warmer and the winters are tending to be colder, and the areas and amounts of precipitation are also shifting. All of these items are predicted based upon an overall warmer atmospheric temperature.
The cause of global warming is human activity, specifically the burning of fossil fuels which releases millions of tons of carbon dioxide into the atmosphere every year. As the amount of carbon dioxide increases in the atmosphere, more of the sun's radiant energy is trapped as heat, causing global warming. Other activities that are contributing to global warming include massive deforestation projects and the emission of methane and several other air pollutants.
Global warming has occurred across the globe, impacting various regions differently. However, some regions that have experienced significant effects of global warming include the Arctic, where temperatures are rising at twice the global average, and low-lying island nations like the Maldives and Tuvalu, which are threatened by sea-level rise. Additionally, areas with glaciers have witnessed rapid melting due to global warming.
Not at all. By giving space to the opposing side, that variously claims that global warming is not happening, is happening but is not a problem, or is happening and is a problem but we have no power to stop it, the news media is unintentionally playing down the problem of global warming. This is a concern for scientists, who say global warming is real but can be stopped if we take decisive action before it is too late.
Global warming has had a variety of effects in different places. Many glaciers have melted or are in the process of melting. Permafrost is thawing. There have been droughts in some locations and floods in others. Hurricanes and other storms are generally getting stronger and more frequent. Climate zones are shifting and various species of animals and plants are changing their ranges.
Islands in the world that are not so high above sea level have already started to be hit by the rising sea levels. Floods have ruined homes already, and if it continues some whole islands will be lost underwater.
It may well be too late to stop some serious effects of global warming. However, we should be optimistic. If we make serious changes now we may be able to live with a future climate for a while (several hundred years) till it cools again.
Some examples of global issues are global warming, human population, health issues...
Global warming.
One of the destructive effects that consumerism has had would be that of "global warming". As society's use of certain chemicals have increased, so has irreversible damage to the environment.
humans cause global warming and pollution
driving cars, pollution and lots more?!
First you try to understand the harmful effects of global warming. Then go to peoples house in your locality and show some percentage of global warming in their house. Then explain them its harmful effects. Then try to tell them how to prevent it. Make posters and stick it on walls. Take out a rally with your friends.
Increased levels of atmospheric carbon dioxide might cause global warming.
While global warming may have some localized benefits, such as longer growing seasons in certain regions, the overall impact is negative. The negative effects of global warming, such as rising sea levels, extreme weather events, and loss of biodiversity, far outweigh any potential positive side effects. It is important to focus on mitigating and adapting to the negative consequences of global warming rather than seeking out potential benefits.
Global warming, Deforestation and Decreasing Biodiversity,etc.
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
There are many dicesases due to air pollution. Also it cause for global warming.
