What is Global warming
In simple word, Global warming can be defined as- An rise in the earth's average atmospheric temperature which may created corresponding changes in climate and that may result from the greenhouse effect.
Global Warming is majorly produced from the greenhouse effect where the greenhouse effect itself is a natural and important phenomenon controlling desirable temperatures for living beings and yes this is a best thing for life on Earth. Generally, without it, there would be no life on Earth as we know it. The neighbor planets to the Earth are Mars with a surface temperature of -53°C and Venus with a surface temperature of +450°C. Earth’s average surface temperature is a suitable with an average of +15degree°C, so just right for life and 33 degree°C hotter than it would be without the greenhouse effect. A major characteristics of this temperature is the reality that water is liquid.
The impact creates by gases in the atmosphere lowering heat loses by radiation back into space. They trap heat energy that is reflected from the Earth’s surface and emitts it some back to space and some back to the Earth. Most of the greenhouse gases are contains of-
- water vapor, H2O
- carbon dioxide, CO2
- methane, CH4
- nitrous oxide, N2O
- CFCs (chlorofluorocarbons).
- Sunlight passes through the Earth’s atmosphere.
- The ground warms up and heat is vomiting from the Earth’s surface.
- Some heat escapes into space but some is consuming by greenhouse gases. It is emitted again and does not escape.
- The Earth’s atmosphere warms up.
If we had no greenhouse gases in the atmosphere, this heat would go straight back into space and the temperature on Earth would fall drastically each night. But some of this heat is consumed by gases in the atmosphere which emit again it as heat energy back to Earth. It’s a bit like having a blanket around the Earth
So to conclude my explanation once again, greenhouse gases are not a bad thing in themselves, but too much of them in the atmosphere leads to an increase in the greenhouse effect and global warming.
What really can cause global warming?

| Causes for global warming |
The reason for current global warming is that humans have been addition of gases called as greenhouse gases to the atmosphere in big proportion for about 100 years. These gases trap heat from the sun and control it from escaping into space the way it naturally would, thus creating the air to heat up. The warmer air then heats up land and water oceans, resulting in all global warming. The major gas is Carbon dioxide produced by burning coal, oil, natural gas, or just about anything else. Other greenhouse gases containing NO2, also produced by burning things, and methane, released during the mining process for coal, oil, and natural gas etc.
We will record that I specifically said current global warming. As has already been mentioned, there have been periods of warming and cooling in the past from natural causes, such as super volcanoes releasing CO2, asteroids hitting the Earth, and tilts in the Earth’s axis. None of these are happening now, which is why we know that humans are the cause of the current warming. However, the fossil fuel companies have spent a great deal of money publicizing the fact that these warmings and cooling have happened in the past without pointing that the causes that removed back then do not exist today, in order to create the impression that the current warming is natural.
Suddenly, the word global warming and climate change are slightly different. Global warming mentioned only to the average overall warming of the globe, while climate change mentioned to overall the impacts of this warming, such as sea level rise, stronger storms, drought, and even local cold snaps due to changes in wind patterns. People who are ignorant of the science often do not understand the difference, and even try to claim that somehow the different terminology proves that global warming is not happening at all.
What is the conclusion of global warming?

| Global warming conclusion |
Reduce our production of CO2 carbon-dioxide from burning fossil fuels like coal, oil, natural gas, etc. to zero as fastly as possible. This would mean replacing fossil fuel power sources with solar, wind, tidal, and other non-fire based electric production. It will mean replacing gasoline and diesel burning vehicles such as cars, trucks, boats, etc. with electric vehicles. An alternative to that would be bio-fuels, where a gasoline or diesel like substance is produced from renewable biological material such as food waste e.g., corn stalks. This is specifically useful for aircraft, that would be harder to produce electric. We can also creates our energy absorbing products more efficient, such as LED lights bulbs and LED TV screens, better insulate our buildings, and so on. So that they needed less energy overall. We necessary to also lower other greenhouse gases for example NO2, methane, and fluorocarbons etc.
Most of these would be discard directly when we ceased burning fuel, since they are byproducts of burning fuel or mining it. We necessary to stop cutting down so several trees, or at least replant them as fast as we cut them down.
What are the environmental impacts of global warming?

| Global warming affects on Greenhouse gases |
Global warming is the rising in average Earth's temperature which majorly creates to climate change and affect Earth in different ways. As per the National Climate Assessment, human influences are the number one created global warming, mainly the carbon pollution we produced by burning fossil fuels and the pollution capturing we control by destroying forests.
More frequent and severe weather-

| Impacts of Global warming |
Increasing temperatures are worsening several types of disasters, containing storms, heat waves, floods, and droughts. A hotter climate formed an atmosphere that can collect, retain, and drop more water, changing weather patterns in such a way that wet areas become wetter and dry areas drier.
Higher death rates-
Global warming is a threat that affects all of us mainly children, the elderly, low income communities, and minorities and in a variety of ways . As temperatures spike, so does the incidence of illness, emergency room visits, and death.
Dirtier air-
Rising temperatures also worsen air pollution by enhancing ground level ozone, that is formed when pollution from cars, factories, and other sources react to sunlight and heat.
Higher wildlife extinction rates-
As humans, we face a host of challenges, but we are probably not the only ones capturing heat. As land and sea undergo fastly changes, the animals that stop them are doomed to disappear if they don't adapt fastly enough.
More acidic oceans-
The earth's marine ecosystems are under pressure as a result of climate change. Oceans are becoming more acidic, due in larger part to their consumption of some of our large amount of emissions. As this acidification accelerates, it poses a serious threat to underwater life, specifically creatures with calcium carbonate shells or skeletons, containing mollusks, crabs, and corals etc.
Higher sea levels-
The polar parts are particularly vulnerable to a warming atmosphere. Average temperatures in the Arctic are Increasing double as fast as they are elsewhere on earth, and the world's ice sheets are melting fast. This not only has grave consequences for the region's people, wildlife, and plants; its most serious effect may be on Increasing sea levels.
What are the most possible consequences of global warming?
 |
| Global warming effects |
1) Larger food production as plants use the larger CO2 level, some deaths from cold, and more living space.
2) The optimal CO2 concentration for plants is around 1200ppm. Humans barely notice any difference up to 1000ppm and beyond.
3) The fact is no one knows what the desirable temperature and CO2 concentration is and whatever anyone tells you in the media or from the activist quarter is whole arbitrary.
4) Even if there was an desirable temperatures and CO2 concentrations these fluctuate over time regardless of mans influence. If we accelerate something we are accelerating something that is going to happen anyway.
5) See on the positive side plants love CO2 and humans like being hot.
