GREENHOUSE EFFECT

Introduction

Natural processes include changes in the Earth's orbit of the sun which causes changes in the sun's intensity, plate tectonics changing the position and size of the continents and volcanic activity changing carbon emissions. Since the early 20th century human activities have significantly changed the composition of the Earth's atmosphere due to the emission of greenhouse gasses.

These human activities include the burning of fossil fuels such as coal, oil, gas and peat in factories, the carbon emissions from car exhausts, methane and nitrous oxide emissions from agriculture and the change of how land is being used for example deforestation and urbanisation. Credit: NASA. Burning fossil fuels produces huge quantities of carbon dioxide CO 2 which is a greenhouse gas. Carbon dioxide along with other greenhouse gasses such as methane, nitrous oxide and chlorofluorocarbons CFCs are changing the composition of the atmosphere and are adding to the greenhouse effect.

These are all heat trapping gasses, as the sun shines down on the Earth its heat is trapped and prevented from escaping back into space similar to how heat is trapped by the glass in a greenhouse.

Increases in greenhouse gas emission leads to increased heat trapping. This trapped heat is causing an increase in Earth's temperature which is have dangerous knock on effects such as melting ice-caps which lead to rising sea levels and flooding.

Effects of climate change

Here, we review information on how plants face redox imbalance caused by climate change, and focus on the role of nitric oxide NO in this response. Life on Earth is possible thanks to greenhouse effect. GHG have natural and anthropogenic origin. However, increasing GHG provokes extreme climate changes such as floods, droughts and heat, which induce reactive oxygen species ROS and oxidative stress in plants. Plants have developed an antioxidant machinery that includes the activity of ROS detoxifying enzymes [e.

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.

Of those gases, known as greenhouse gases , water vapour has the largest effect. The origins of the term greenhouse effect are unclear. Fourier, however, neither used the term greenhouse effect nor credited atmospheric gases with keeping Earth warm. This radiation, unlike visible light, tends to be absorbed by the greenhouse gases in the atmosphere, raising its temperature. Despite its name, the greenhouse effect is different from the warming in a greenhouse , where panes of glass transmit visible sunlight but hold heat inside the building by trapping warmed air.

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.

Causes and greenhouse effect

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.

GREENHOUSE EFFECT

The effect is natural and not new. When sunlight hits the surface of the earth it is absorbed and the visible light short wave radiation is converted to heat infrared or long wave radiation Fig. Figure 1. Some gases in the atmosphere the so called greenhouse gases: such as carbon dioxide, water vapour, methane, etc.

Весь вечер оказался сплошной комедией ошибок. В его ушах звучали слова Стратмора: Не звони, пока не добудешь кольцо. Внезапно он почувствовал страшный упадок сил. Если Меган продала кольцо и улетела, нет никакой возможности узнать, где оно. Беккер закрыл глаза и попытался сосредоточиться. Итак, каков следующий шаг. Он решил подумать об этом через минуту.

What is the greenhouse effect?

После чего вошел в номер и включил свет. Немец не ожидал такого оборота. - Wasmachst… - Помолчите! - Беккер перешел на английский.  - У вас в номере проститутка? - Он оглядел комнату. Роскошная обстановка, как в лучших отелях. Розы, шампанское, широченная кровать с балдахином. Росио нигде не .

Лестница, ведущая наверх, была пуста. Его жертва не приготовилась к отпору. Хотя, быть может, подумал Халохот, Беккер не видел, как он вошел в башню. Это означало, что на его, Халохота, стороне фактор внезапности, хотя вряд ли он в этом так уж нуждается, у него и так все козыри на руках. Ему на руку была даже конструкция башни: лестница выходила на видовую площадку с юго-западной стороны, и Халохот мог стрелять напрямую с любой точки, не оставляя Беккеру возможности оказаться у него за спиной, В довершение всего Халохот двигался от темноты к свету. Расстрельная камера, мысленно усмехнулся .
