The atmosphere is a dynamic fluid that is continually in motion. Both its physical properties and its rate and direction of motion are influenced by a variety of factors, including solar radiation , the geographic position of continents , ocean currents , the location and orientation of mountain ranges, atmospheric chemistry , and vegetation growing on the land surface.

Some scientists predict that we only have 8 months to act or it will be too late. According to NASA scientists, climate has experienced its most important change during the midth century. When we talk about climate change , we have to talk about the greenhouse effect. The greenhouse effect increases global warming when the atmosphere traps heat radiating from Earth toward space.

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. Coal-burning power plants are by far the biggest polluters. Curbing dangerous climate change requires very deep cuts in emissions, as well as the use of alternatives to fossil fuels worldwide.

And scientists continue to develop new ways to modernize power plants, generate cleaner electricity, and burn less gasoline while we drive. The challenge is to be sure these solutions are put to use and widely adopted. They also said the odds of similar droughts happening in the future had roughly doubled over the past century.

So global warming could turn, say, a category 3 storm into a more dangerous category 4 storm. In , Hurricane Katrina—the costliest hurricane in U. The impacts of global warming are being felt across the globe. Extreme heat waves have caused tens of thousands of deaths around the world in recent years. And in an alarming sign of events to come, Antarctica has been losing about billion metric tons of ice per year since This rate could speed up if we keep burning fossil fuels at our current pace, some experts say, causing sea levels to rise several meters over the next 50 to years.

The United States comes in second. And America is still number one, by far, in cumulative emissions over the past years. Our responsibility matters to other countries, and it should matter to us, too. But in order to avoid the worst effects of climate change, we need to do a lot more—together with other countries—to reduce our dependence on fossil fuels and start using clean energy instead.

In , the U. Environmental Protection Agency pledged to reduce carbon pollution from our power plants by nearly a third by , relative to levels, through its Clean Power Plan. But fast-forward to , and under the Trump Administration, the EPA proposed repealing this critical tool for curbing climate change. Likewise, while under the Obama administration, the U. Department of Transportation proposed carbon pollution and fuel economy standards intended to cut emissions through the s, under Trump administration, the DOT is working to roll back those clean vehicle safeguards that protect the climate and our health.

Fortunately, state leaders—including in car country itself—recognize that clean transportation must remain a priority if we are to address the costly risks of climate change and protect public health. And regional efforts around the country are helping to boost the electric car market , which saw an increase in sales for over Our clean energy economy is growing too, despite federal efforts to derail it.

In , wind employment grew by 32 percent and solar jobs increased by 25 percent. Globally, at the United Nations Conference on Climate Change in Paris, countries—including the United States, at the time—agreed to pollution-cutting provisions with a goal of preventing the average global temperature from rising more than 1.

Scientists say we must stay below a two-degree increase to avoid catastrophic climate impacts. Under the terms of the Paris agreement, participating nations will meet every five years, starting in , to revise their plans for cutting CO2 emissions. Beginning in , they will also have to publicly report their progress. More than 25 cities in 17 states, with populations totaling more than 5 million have adopted resolutions that will enable them to get percent of their electricity from renewable sources like wind and solar.

Even better, a new initiative by former New York City mayor Michael Bloomberg gives the urban layer of this movement a boost. Make conserving energy a part of your daily routine and your decisions as a consumer. 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. And while new federal and state standards are a step in the right direction, much more needs to be done.

The western city of Ahmedabad is preparing residents to cope with the longer and more intense heat waves sweeping across South Asia—and inspiring other Indian cities and states to follow suit. The most widespread, damaging storms on earth are getting worse, and climate change is a big reason why. The U.

Healing the planet starts at home—in your garage, in your kitchen, and at your dining-room table. Short answer: Yes. Even a seemingly slight average temperature rise is enough to cause a dramatic transformation of our planet.

What is climate change? The definition, causes and effects

The effects of climate change span the physical environment , ecosystems and human societies. It also includes the economic and social changes which stem from living in a warmer world. Human-caused climate change is one of the threats to sustainability. Many physical impacts of climate change are already visible, including extreme weather events, glacier retreat , [7] changes in the timing of seasonal events e. Climate change has already impacted ecosystems and humans.

During the course of global warming, the energy balance and thus the temperature of the earth change, due to the increased concentration of greenhouse gases, which has a significant impact on humans and the environment. It is not scientifically possible to assign individual weather events to the current climate change, however, it can be statistically proven that global warming will increase the probability of extreme weather events. The indirect consequences of climate change, which directly affect us humans and our environment, include:. As the global climate is a highly interconnected system that is influenced by many different factors, the consequences usually result in positive or negative feedback effects. This refers to developments that are self-enhancing due to the occurrence of certain conditions. A common example is the ice-albedo feedback, which refers to the melting of the polar caps. According to this, extensive ice surfaces have a cooling effect on the global climate, as a high proportion of radiation is reflected.

What is climate change? Is it the same as global warming? What are its main causes and consequences? Is it a lie? Find everything about climate change bel ow! Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet regarding temperature, precipitation, and wind that are especially caused by human activities.

Climate change is the catch-all term for the shift in worldwide weather phenomena associated with an increase in global average temperatures. It's real and temperatures have been going up around the world for many decades.

Climate change causes a variety of physical impacts on the climate system. The physical impacts of climate change foremost include globally rising temperatures of the lower atmosphere, the land, and oceans. Temperature rise is not uniform, with land masses and the Arctic region warming faster than the global average. Effects on weather encompass increased heavy precipitation , reduced amounts of cold days, increase in heat waves and various effects on tropical cyclones. The enhanced greenhouse effect causes the higher part of the atmosphere, the stratosphere , to cool.

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.

Climate change

Компьютер открыл перед ним мир, о существовании которого он даже не подозревал, и вскоре заполнил всю его жизнь. Повзрослев, он начал давать компьютерные уроки, зарабатывать деньги и в конце концов получил стипендию для учебы в Университете Досися. Вскоре слава о фугуся-кисай, гениальном калеке, облетела Токио. Со временем Танкадо прочитал о Пёрл-Харборе и военных преступлениях японцев. Ненависть к Америке постепенно стихала. Он стал истовым буддистом и забыл детские клятвы о мести; умение прощать было единственным путем, ведущим к просветлению. К двадцати годам Энсей Танкадо стал своего рода культовой фигурой, представителем программистского андеграунда.

Он… он был?. - Да, убит. - Но… но это невозможно! - У немца перехватило дыхание.  - Я там. У него случился инфаркт. Я сам. Никакой крови.

 И где же это кольцо? - гнул свое Беккер. Клушар, похоже, не расслышал. Глаза его отсутствующе смотрели в пространство. - Странное дело, ей-богу, все эти буквы - ни на один язык не похоже. - Может быть, японский? - предположил Беккер.

What are the effects of climate change?

Прекрасное место для смерти, - подумал Халохот.  - Надеюсь, удача не оставит. Беккер опустился на колени на холодный каменный пол и низко наклонил голову. Человек, сидевший рядом, посмотрел на него в недоумении: так не принято было вести себя в храме Божьем. - Enferno, - извиняясь, сказал Беккер.

Нужно выключить ТРАНСТЕКСТ. У нас… - Он нас сделал, - сказал Стратмор, не поднимая головы.  - Танкадо обманул всех. По его тону ей стало ясно, что он все понял. Вся ложь Танкадо о невскрываемом алгоритме… обещание выставить его на аукцион - все это было игрой, мистификацией. Танкадо спровоцировал АНБ на отслеживание его электронной почты, заставил поверить, что у него есть партнер, заставил скачать очень опасный файл.

Проследите, чтобы он вылетел домой немедленно. Смит кивнул: - Наш самолет в Малаге.  - Он похлопал Беккера по спине.  - Получите удовольствие, профессор. Вы летали когда-нибудь на Лирджете-60.

Это была цифровая мультимедийная трансляция - всего пять кадров в секунду. На экране появились двое мужчин: один бледный, коротко стриженный, другой - светловолосый, с типично американской внешностью. Они сидели перед камерой наподобие телеведущих, ожидающих момента выхода в эфир.

ГЛАВА 93 Причастие. Халохот сразу же увидел Беккера: нельзя было не заметить пиджак защитного цвета да еще с кровавым пятном на боку. Светлый силуэт двигался по центральному проходу среди моря черных одежд. Он не должен знать, что я.  - Халохот улыбнулся.
