Global Warming

Attribution of recent climate change is the effort to scientifically ascertain mechanisms responsible for recent global warming and related climate changes on Earth. This is the period when human activity has grown fastest and observations of the atmosphere above the surface have become available. According to the Intergovernmental Panel on Climate Change IPCC , it is "extremely likely" [5] that human influence was the dominant cause of global warming between and Some of the main human activities that contribute to global warming are: [8]. In addition to human activities, some natural mechanisms can also cause climate change , including for example, climate oscillations , changes in solar activity , and volcanic activity. Multiple lines of evidence support attribution of recent climate change to human activities: [9]. The IPCC's attribution of recent global warming to human activities is a view shared by the scientific community, [10] [11] [12] and is also supported by other scientific organizations worldwide [13] see also: Scientific consensus on climate change.

Some of the incoming sunlight is reflected directly back into space, especially by bright surfaces such as ice and clouds, and the rest is absorbed by the surface and the atmosphere. Much of this absorbed solar energy is re-emitted as heat longwave or infrared radiation. The atmosphere in turn absorbs and re-radiates heat, some of which escapes to space. Any disturbance to this balance of incoming and outgoing energy will affect the climate. For example, small changes in the output of energy from the Sun will affect this balance directly.

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.

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.

In the following viewpoint, Canadell argues that recent efforts to improve energy efficiency and increase the use of clean energy have contributed to a stalling in fossil fuel emissions. However, Canadell contends that governments will need to increase their efforts to meet the climate goals established in the Paris Agreement. He compares the successes and shortcomings of China, the United States, India, Australia, and the European Union in reducing emissions. He examines the practice of storing carbon dioxide underground through carbon capture and storage CCS and concludes that thousands of CCS facilities will be necessary to meet climate goals. In the following viewpoint, Thomas argues that politicians use the issue of climate change as an excuse for the government to interfere in the lives of private citizens.

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.

Global Warming is viewed as an overall warming of the planet based on average temperature over the entire surface and climate change are changes in regional​.

Attribution of recent climate change


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. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities.

Так и есть, примерно через каждые двадцать строк появляется произвольный набор четырех знаков. Сьюзан пробежала все их глазами. PFEE SESN RETM - Альфа-группы из четырех знаков, - задумчиво проговорила Сьюзан.  - И частью программы они явно не являются. - Да бросьте вы это, - проворчал Джабба.  - Хватаетесь за соломинку.

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 немного погорячилась.

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.
