To understand what this means for humanity, it is necessary to understand what global warming is, how scientists know it's happening, and how they predict future climate of global warming.

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.

Overview of Climate Change Science

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.

There is broad-based agreement within the scientific community that climate change is real. The U. Environmental Protection Agency, the National Aeronautics and Space Administration, and the National Oceanic and Atmospheric Administration concur that climate change is indeed occurring and is almost certainly due to human activity.

The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide.

Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases that cause climate change. Today it is at about ppm, a level not reached in more than , years. Rising sea levels due to the melting of the polar ice caps again, caused by climate change contribute to greater storm damage; warming ocean temperatures are associated with stronger and more frequent storms; additional rainfall, particularly during severe weather events, leads to flooding and other damage; an increase in the incidence and severity of wildfires threatens habitats, homes, and lives; and heat waves contribute to human deaths and other consequences.

While consensus among nearly all scientists, scientific organizations, and governments is that climate change is happening and is caused by human activity, a small minority of voices questions the validity of such assertions and prefers to cast doubt on the preponderance of evidence. While the latter is generally true, decades of data and analysis support the reality of climate change—and the human factor in this process.

In any case, economists agree that acting to reduce fossil fuel emissions would be far less expensive than dealing with the consequences of not doing so. What flashcards would you like to see?

Study of Impacts of Global Warming on Climate Change: Rise in Sea Level and Disaster Frequency

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.

The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide.

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.

Similarly, the terms "weather" and "climate" are sometimes confused, though they refer to events with broadly different spatial- and timescales. Weather refers to atmospheric conditions that occur locally over short periods of time—from minutes to hours or days. Familiar examples include rain, snow, clouds, winds, floods or thunderstorms. Climate, on the other hand, refers to the long-term regional or even global average of temperature, humidity and rainfall patterns over seasons, years or decades. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally produced warming and the effects it has on our planet. Most of the current warming trend is extremely likely greater than 95 percent probability the result of human activity since the s and is proceeding at an unprecedented rate over decades to millennia. These changes have a broad range of observed effects that are synonymous with the term.

Earth's climate is changing. Multiple lines of evidence show changes in our weather, oceans, ecosystems, and more. Human activities are contributing to climate change, primarily by releasing billions of tons of carbon dioxide CO 2 and other heat-trapping gases, known as greenhouse gases, into the atmosphere every year. The more greenhouse gases we emit, the larger future climate changes will be. Human activities, like driving, manufacturing, electricity generation, and the clearing of forests contribute to greenhouse gas emissions and warm the planet.

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.

What is the difference between global warming and climate change?

 Танкадо слишком умен, чтобы предоставить нам такую возможность, - возразил Стратмор. Сьюзан испытала от этих слов странное облегчение. - У него есть охрана. - В общем-то. - Он прячется в укрытии. Стратмор пожал плечами.

Одно дело - заставить нас рассказать про ТРАНСТЕКСТ, и совершенно другое - раскрыть все государственные секреты. Фонтейн не мог в это поверить. - Вы полагаете, что Танкадо хотел остановить червя. Вы думаете, он, умирая, до последний секунды переживал за несчастное АНБ. - Распадается туннельный блок! - послышался возглас одного из техников.

Global Warming 101

Он швырнул Беккеру ключи от веспы, затем взял свою девушку за руку, и они, смеясь, побежали к зданию клуба. - Aspetta! - закричал Беккер.  - Подождите.

Я сейчас же отправлю ее домой. - Боюсь, вы опоздали, - внушительно заявил Беккер и прошелся по номеру.  - У меня к вам предложение. - Ein Vorschlag? - У немца перехватило дыхание.

Иногда она видела в нем что-то от Дэвида. У них было много общего: настойчивость, увлеченность своим делом, ум. Иногда ей казалось, что Стратмор без нее пропадет; ее любовь к криптографии помогала коммандеру отвлечься от завихрений политики, напоминая о молодости, отданной взламыванию шифров. Но и она тоже многим была обязана Стратмору: он стал ее защитником в мире рвущихся к власти мужчин, помогал ей делать карьеру, оберегал ее и, как сам часто шутил, делал ее сны явью.
