For the warming over the last century, there is no convincing alternative explanation. Global data show that was the warmest year on record and the third consecutive year for record global average surface temperatures.

The climate of an area determines its seasons and when they come and go. This, in turn, affects the type of plants that grow and which animals survive. The species and places we love depend on intricate ecosystems, and even small changes to the climate can disrupt the delicate balance of nature.
Global warming is expected to have far-reaching, long-lasting and, in many cases, devastating consequences for planet Earth. Global warming , the gradual heating of Earth's surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide CO2 , methane and other greenhouse gases into the atmosphere. One of the most immediate and obvious effects of global warming is the increase in temperatures around the world. The average global temperature has increased by about 1.
Global Warming 101
Global Warming - Impacts and Future Perspective. Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be main contributors to such increases in average global temperatures. The climate change, caused by rising emissions of carbon dioxide from vehicles, factories and power stations, will not only effects the atmosphere and the sea but also will alter the geology of the Earth. Emissions of carbon dioxide due to our use of fossil energy will change the climate and the temperature is estimated to increase by 2 to 6 o Celsius within year , which is a tremendous increase from our current average temperature of 1. This may cause huge changes to our civilization, both positive and negative, but the total impact on our society is currently very uncertain. Forecasts indicate that major storms could devastate New York City in next decade whereas Gulf countries will get affected badly well before.
Global warming , the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Increases in greenhouse gases —i. Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately. Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy flooding , and wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure. Temperature increases related to global warming have been the most pronounced at the poles, where they often make the difference between frozen and melted ice. Polar bears rely on small gaps in the ice to hunt their prey.
Climate change includes both global warming driven by human emissions of greenhouse gases , and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change , since the midth century humans have had unprecedented impact on Earth's climate system and caused change on a global scale. Temperature rise on land is about twice the global average increase, leading to desert expansion and more common heat waves and wildfires. It further magnifies risks of flooding, infectious diseases and extreme heat, with the World Health Organization calling climate change the greatest threat to global health in the 21st century. Habitat destruction. Many arctic animals rely on sea ice, which has been disappearing in a warming Arctic.

Jump to navigation. And yes, it's really happening. Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. And scientists say that unless we curb global-warming emissions, average U. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the greenhouse effect. In the United States, the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution, producing about two billion tons of CO2 every year.
Many researchers, engineers and environmentalists are expressing deep concerns about changes in the overall climate of the planet. Fossil fuels are being continuously used to produce electricity. The burning of these fuels produces gases like carbon dioxide, methane and nitrous oxides which lead to global warming.
The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions and an increase in the number, duration and intensity of tropical storms. Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.
Climate change is a global challenge that has no borders and to combat it requires coordinated work by all countries. In these pages, we tackle the subject from an objective, scientific viewpoint , discussing the causes and consequences of climate change and how it should be tackled. One of the MOST amazing video's and explinations on climate change. The main cause of climate change is global warming, which has many negative consequences on physical, biological and human systems, as well as other effects.
Хейл - Северная Дакота. Она замерла и непроизвольно задержала дыхание, чувствуя на себе взгляд Хейла. Сьюзан повернулась, и Хейл, пропуская ее вперед, сделал широкий взмах рукой, точно приветствуя ее возвращение в Третий узел. - После вас, Сью, - сказал .
