Global warming refers to the rising average temperature of Earth’s atmosphere and oceans and its projected continuation. In the last 100 years, Earth’s average surface temperature increased by about 0.8 °C (1.4 °F) with about two thirds of the increase occurring over just the last three decades. Warming of the climate system is unequivocal, and scientists are more than 90% certain most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and burning fossil fuels. These findings are recognized by the national science academies of all the major industrialized countries
Issue of Global Warming
Despite a scientific consensus on the subject, some people don’t think global warming is happening at all. There are several reasons for this:
- They don’t think the data show a measurable upward trend in global temperatures, either because we don’t have enough long-term historical climate data or because the data we do have isn’t clear enough.
- A few scientists think that data is being interpreted incorrectly by people who are already worried about global warming. That is, these people are looking for evidence of global warming in the statistics, instead of looking at the evidence objectively and trying to figure out what it means.
- Some argue any increase in global temperatures we are seeing could be a natural climate shift, or it could be due to other factors than greenhouse gases.
Impacts of Global Warming
The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive polar regions. And the effects of rising temperatures aren’t waiting for some far-flung future. They’re happening right now. Signs are appearing all over, and some of them are surprising. The heat is not only melting glaciers and sea ice, it’s also shifting precipitation patterns and setting animals on the move.
Some impacts from increasing temperatures are already happening.
- Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
- Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
- Sea level rise became faster over the last century.
- Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
- Precipitation (rain and snowfall) has increased across the globe, on average.
- Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.
Solutions of Global Warming
Obviously there is no one magic solution to the problem of global warming. There are instead hundreds of questions that need to be asked and addressed so as to create an overall Earth plan that will develop our planet wisely. The changes we can make, both large and small when combined will curtail global warming for the better. In this section we discuss the latest green designs, products and ideas as yet undeveloped that will reduce environmental damage overall.
Stop Global Warming
Given below ideas help us to avoid global warming facts.
Reduce : The amount of energy you consume and start using renewable energy sources, such as wind power and solar power. Sign up for Green Energy with your local power provider. If they don’t have it, then tell them to get it.
Reuse : By using products made with recycled materials. Make or buy a compost bin to use your organic waste as fertilizer for your trees, shrubs, and garden.
Recycle : All materials to your best ability in your local area.
