Global Warming is the increase of Earth’s average surface temperature attributable to result of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which entice heat that would otherwise escape from Earth. This is an often a kind of atmospheric phenomenon and is called a greenhouse effect. Scientific understanding of global warming has been increasing. In its fifth assessment (AR5) in 2014 the Intergovernmental Panel on climate change (IPCC) reported that scientists were more than 95% bound that the majority of world warming is caused by increasing concentrations of greenhouse gases and alternative human activities.
Global warming is predicted to have far-reaching, long-lasting and, in several cases, devastating consequences for planet Earth. For some years, heating, the gradual heating of surface, oceans and atmosphere, was a subject of heated discussion within the scientific community. Today, the overwhelming agreement of researchers is that heating is real and is caused by human action, primarily the burning of fossil fuels that pump greenhouse emission (CO2), gas and alternative greenhouse gases into the atmosphere. Global warming is having a measurable effect on the planet right now, in a variety of ways. Ice is melting in both polar ice caps and mountain glaciers. Lakes around the world, including Lake Superior, are warming rapidly – in some cases faster than the surrounding environment. Animals are changing migration patterns and plants are changing the dates of activity likes shedding of leaves and pollination of plants. One of the foremost immediate and obvious effects of global warming is the increase in temperatures round the world. The average global temperature has multiplied by about 1.4 degrees Fahrenheit over the past 100 years, according to the National Oceanic and Atmospheric Administration. A report by the World Meteorological Organization released July 3, 2014, said that deaths from heat increased by more than 2,000 percent over the previous decade. Extreme weather is an impact of global warming. Whereas experiencing some of the hottest summers on record, much of the United States also has been experiencing colder than normal winters.
Global warming may also lead to extreme weather apart from cold or heat extremes. For instance, hurricane formations will change. Although this is still a subject of active scientific research, current computer models of the atmosphere indicate that hurricanes are more likely to become less frequent on a global basis, though the hurricanes that do form may be more intense. Lightening is another weather feature that is being affected by global warming. The researchers of the study found a 12 percent increase in lightning activity for every 1.8 degree F of warming in the atmosphere.
Scientists project that extreme weather events, such as heat waves, droughts, blizzards and rainstorms will continue to occur more often and with bigger intensity because of heating, according to Climate Central. Climate models forecast that global warming will cause climate patterns worldwide to expertise vital changes. These changes will likely include major shifts in wind patterns, annual precipitation and seasonal temperatures variations. Glacial retreat, too, is an evident result of global warming.
Only 25 glaciers bigger than 25 acres are currently found in Montana’s Glacier National Park, where about 150 glaciers were once found. An identical trend is seen in glacial areas worldwide. Global ocean levels have risen up about 8 inches since 1870, in keeping with the Environmental Protection Agency, and therefore the rate of increase is predicted to accelerate within the coming years. If current trends continue, several coastal areas, wherever roughly half the Earth’s human population lives, are inundated. Agricultural systems will likely be dealt a crippling blow. Though growing seasons in some areas will expand, the combined impacts of drought, severe weather, lack of snowmelt, greater number and diversity of pests, lower groundwater tables and a loss of productive land might cause severe crop failures and livestock shortages worldwide.
There are several ways through which we can help reducing global warming. If climate change continues unchecked, these impacts are almost certain to get worse. Unfortunately, those who will be hit hardest and first by the impacts of a changing climate are likely to be the poor and vulnerable, especially those in the least developed countries. Developed countries must take a leadership role in providing financial and technical help for adaptation. Planting trees is one suggested response to climate change, because trees absorb carbon dioxide, the most abundant greenhouse gas produced by human activity, as they grow. Renewable energy sources such as solar, wind, geothermal and bio-energy are available around the world. Renewable technologies can be deployed quickly, are increasingly cost-effective, and create jobs while reducing pollution. Research into and development of the next generation of low-carbon technologies will be critical to deep mid-century reductions in global emissions.
