Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture.

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.

What is climate change? Is it the same as global warming? What are its main causes and consequences?

Climate Change: Meaning, Definition, Causes, Examples And Consequences

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.

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. This, in combination with extreme weather events, leads to negative effects on human health.

Although the scientific process is always open to new ideas and results, the fundamental causes and consequences of climate change have been established by many years of scientific research, 1 are supported by many different lines of evidence, and have stood firm in the face of careful examination, repeated testing, and the rigorous evaluation of alternative theories and explanations. This chapter provides a brief overview of some basic facts about the risks posed by climate change see Box 2. Earth is warming. Warming has also been observed specifically in the lower atmosphere 3 and the upper oceans.

Causes of climate change

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 emission of greenhouses gases GHGs , 6 which move about in the atmosphere, is a major cause of global climate change. Even with drastic GHG reductions, almost half of humans will face deadly heat. Although a number of U.

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.

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. That year Earth's surface temperature was 1.

К тому же Сьюзан написала свой маячок на новом гибридном языке, именуемом LIMBO, поэтому не приходилось удивляться, что Стратмор с ним не справился. - Я возьму это на себя, - улыбнулась она, вставая.  - Буду у своего терминала. - Как ты думаешь, сколько времени это займет. - Ну… - задумалась Сьюзан.

Стратмор сощурил. - А ты как думаешь. И уже мгновение спустя ее осенило. Ее глаза расширились. Стратмор кивнул: - Танкадо хотел от него избавиться. Он подумал, что это мы его убили. Он почувствовал, что умирает, и вполне логично предположил, что это наших рук .

Такси все еще продолжало крутиться, и в ожидании столкновения он сжался в комок. Раздался оглушающий треск гофрированного металла. Но Беккер не ощутил боли. Неожиданно он оказался на открытом воздухе, по-прежнему сидя на веспе, несущейся по травяному газону. Задняя стенка ангара бесследно исчезла прямо перед .
