BBC News - Siberia landscape scarred by climate change
https://www.bbc.co.uk/news/world-54195656

I will like you people to click on the link above, you can check (in a video) how scientists are warning about the issue of global warning which is as a result of green house gasses which are produced as a result of human activities like deforestation and industrial gaeses produced as waste etc. Now in Siberia, scientists are warning that the frozen grounds in the country also known as the permafrost are thawing (changing from solid to liquid), in such a way certain areas can even turn into lake.

I have a post about global warming on 'politics and society board'. It reveals what green houses gases are and the danger they can pose later in the future. Aside this news, there are other news I have read about how global warming is also turning the ice in the Antarctica and Greenland Denmark into water adding to the rising water sea level.

Global warming is real, the world now know that as it is evident in the rising temperature in the world, many ice bags are melting, this is noticed in Denmark and many regions of the world and it is due to the increase in the heat from the sun that is reaching the earth, the water sea level is yearly increasing. It has also been said that increase in water level in the next 10 years will be more and will be mainly due to global warming.

Three positions on global warming are:

1. That global warming is not occurring and so neither is climate change
2. That global warming and climate change are occurring, but these are natural, cyclic events unrelated to human activity
3. That global warming is occurring as a result primarily of human activity and so climate change is also the result of human activity

But, if we can reason with the scientists, we will believe that global warming is mainly due to human activities because carbon particles and many other green house gases have been linked to it, it makes the sun heat to penetrate more into the earth.

The green house gases are
CO2 or carbon dioxide
Methane
Nitrous oxide in parean (laughing gas)
Fluorinated gases
Sulphur hexafluoride

These gases including black carbon can be responsible for global warming, that is why they should not be too much in the atmosphere but there should be some natural produced ones like CO2 to certain extent so that the world will not become too cold in a way sun will not be able to penetrate certain amount of heat also. So, the concetraction of the green house gasses are to certain level. If low, it will result to cold earth and if too much, it will lead to warm earth (global warming). But out of all, scientists link CO2 more to global warming.

The trees breath in CO2 in a way it takes up carbon, but in the world of today, trees are reducing due to several human activities, this decrease the amount of CO2 intake by tress. Humans also increase, and we breath out CO2, and contribute to the atmospheric carbon. Also there many ways CO2 and those green houses gasses listed above are produced by human activities, leading to global warming.





From the above graph, you will noticed how carbon emitted into the atmosphere as been increasing drastically which is linked to human activities.

Specifically, gases released primarily by the burning of fossil fuels and the tiny particles produced by incomplete burning trap the sun’s energy in the atmosphere. Scientists call these gases “greenhouse gases” (GHGs) because they act like the wrong way reflective glass in our global greenhouse. Scientists call the tiny particles ‘black carbon’ (you call it soot or smoke) and attribute their warming effect to the fact that the resulting layer of black particles in the lower atmosphere absorbs heat like a black blanket.

Scientists date the beginning of the current warming trend to the end of the 18th or beginning of the 19th century when coal first came into common use. This warming trend has accelerated as we have increased our use of fossil fuels to include gasoline, diesel, kerosene and natural gas, as well as the petrochemicals (plastics, pharmaceuticals, fertilizers) we now make from oil.

Scientists attribute the current warming trend to the use of fossil fuels because using them releases into the atmosphere stores of carbon that were sequestered (buried) millions of years ago. The addition of this “old” carbon to the world’s current stock of carbon, scientists have concluded, is what is heating our earth which causes global warming.

We people in the world should be able to regulate the green house gases in a constant state in a way it will not be less or too much so that we can maintain certain amount of heat emitted by the sun that will penetrate into the earth.
