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.
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.
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. As we just have seen, the greenhouse effect does have natural origin but humans have a strong responsibility in the fact that its concentrations constantly increase.

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.
Human action is causing an increase in global temperature. For that reason, the greenhouse effect, far from being our great ally as was the case in the past, is now a risk to our survival. The flooding of coastal cities, the desertification of fertile areas, the melting of glacial masses and the proliferation of devastating hurricanes are just some of the main consequences. Global warming is having a profound impact on the processes of soil degradation and is contributing to the desertification of the most arid areas on the planet. The increase in the global temperature of the planet produces a rise in the level of the sea, which will cause the disappearance of islands and coastal cities. The greenhouse effect is a natural phenomenon and is beneficial for us. Certain gases in the atmosphere retain part of the thermal radiation emitted by the Earth's surface after being heated by the sun, this maintains the planet's temperature at a level suitable for the development of life.
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.

Research has also evaluated actions that could be taken—and in some cases are already being taken—to limit the magnitude of future climate change and adapt to its impacts. In the United States, a series of reports by the U. Internationally, scientific information about climate change is periodically assessed by the Intergovernmental Panel on Climate Change IPCC , most recently in
This very real threat has dire consequences for our earth and our health. From the causes to prevention, learn the facts you need know.
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.
Он вздохнул и задал единственный вопрос, который пришел ему в голову; - Как выглядит эта девушка. - Era un punqui, - ответила Росио. Беккер изумился. - Un punqui.
Как и все другие крупные базы данных - от страховых компаний до университетов, - хранилище АНБ постоянно подвергалось атакам компьютерных хакеров, пытающих проникнуть в эту святая святых.
Мидж кивнула. В глубине души она понимала, что абсурдно обвинять в нерадивости Стратмора, который был беззаветно предан своему делу и воспринимал все зло мира как свое личное. Попрыгунчик был любимым детищем коммандера, смелой попыткой изменить мир. Увы, как и большинство других поисков божества, она закончилась распятием. - Хорошо, - сказала .
Я не намерен информировать президента за спиной директора. У нас возник кризис, и я пытаюсь с ним справиться. - Он задумчиво посмотрел на. - Я являюсь заместителем оперативного директора агентства.
Хорошо бы их вытянуть. Терпи, - сказал он. - Терпи. Потом закрыл глаза и глубоко вздохнул. Беккер не сразу почувствовал, что его кто-то подталкивает.
Zumo de arandano, - с удивлением услышал он собственный голос. - Клюквенный сок. Бармен смотрел на него озадаченно.
