Global Warming

Global warming is the phenomenon of unprecedented increase in the temperature of earth. Global warming is also referred as to climate change. Glaciers are melting at very high ratio, which is very alarming for keeping the normal temperature of the earth maintain.

Climate change is caused by many issues. The issues can be divided into two categories I.e. “Natural” and “Human influences”. Natural causes of global warming are greenhouse gases and the eruption of volcano etc. human influences on global warming are industrial revolution, mining and deforestation etc. it has now been confirmed that humans have caused the increase in global warming by releasing many heat trapping gases. The release of these greenhouse gases to the atmosphere is at higher level in the past few decades compare to the last few centuries.

Global warming does not only have impact on the rising temperature of earth but it already have bad impacts on extreme weather conditions, shifting wildlife population and habitats, rising seas and a range if other impacts. These changes are caused in the consequence of human adding heat trapping gases at very high ratio with continuity to the atmosphere.

Human activity isn't the only factor that affects Earth's climate. Volcanic eruptions and variations in solar radiation from sunspots, solar wind, and the Earth's position relative to the sun also play a role. So do large-scale weather patterns such as El Niño. But climate models that scientists use to monitor Earth’s temperatures take those factors into account. Changes in solar radiation levels as well as minute particles suspended in the atmosphere from volcanic eruptions, for example, have contributed only about two percent to the recent warming effect. The balance comes from greenhouse gases and other human-caused factors, such as land use change.

The release of carbon dioxide to the atmosphere is increased by humans, the gas that would take centuries the temperature of earth now takes few years. This rise in temperature is happening no at very high level after the industrial revolution.

As the mercury rises, the climate can change in unexpected ways. In addition to sea levels rising, weather can become more extreme. This means more intense major storms, more rain followed by longer and drier droughts—a challenge for growing crops—changes in the ranges in which plants and animals can live, and loss of water supplies that have historically come from glaciers.

But the question is How to stop the global warming?

The question cannot be answered specifically but speaking generally reduce your own carbon footprint by following a few easy steps. Make conserving energy a part of your daily routine and your decisions as a consumer. When you shop for new appliances like refrigerators, washers, and dryers, look for products with the government’s Energy Star label; they meet a higher standard for energy efficiency than the minimum federal requirements. When you buy a car, look for one with the highest gas mileage and lowest emissions. You can also reduce your emissions by taking public transportation or carpooling when possible.
