Global warming is a real disaster in this modern world. It is the Earth’s global temperature which would rise in the future, but not sure by how much. If we continue to emit as much GHG(greenhouse gas ) as we are producing right now, then the 21st century would be hotter than the 20th century.
The earth’s temperature would go up by 1.8 to 4 degrees. Global warming and the
Different climate models have different things to say about warming that is to take place. Heat would differently be warmer over lands and ocean. It would be hotter on earth, and colder comparatively over the seas. The temperature would be higher on high latitudes than it would be over tropics and mid-latitudes.
The water cycle would speed up; more water vapor means more rains. It would rain more by 3-5%. This could be a 1% or 8% level. Some places there would be more snow, and other areas will see less precipitation.
Grievous Effects on the Earth Due To Global Warming
In this article “Global warming and the changing face of the earth”. we will see as the climate becomes hotter, the snow and ice would start melting, this amount of melting of ice sheets and glaciers is one extreme and on the other extreme is something which means lesser rains during winters.
The amount of ice and snow melts over the Arctic and Antarctica which says this would continue in the 21st century and there is nothing specific about how much ice would melt in all.
There is a new phenomenon which is melting glaciers and ice streams and rising sea level, the ocean water gets warmer which means it expands, the volume increases, and thus the sea level goes higher.
RISING SEA LEVEL
By 2100, the estimates are that the sea level would rise between 20 cm to 50 cm. The heating up of the ocean floor means 75% future sea-level rise according to the most estimates. It is the oceans which would take care of the climate of the earth by absorbing extra heat and carbon dioxide from the atmosphere. But, this could create problems such as CO2 mixing with seawater to form carbonic acid.
The pH of oceans goes down by 0.1 pH since we were in the pre-industrialized era and this means further acidification of .14 to .35 by 2100 and which means organisms of the sea would die, and so would what is called marine microorganisms.
The other aspect of the climate that would be affected is the thermohaline circulation. Differences in salinity and temperature drive this. Salinity and temperature are affected by global warming, in some places, large ocean currents could be stopped, or shut down in some ocean parts, which would change the climate.
As is well known, hurricanes, typhoons, and cyclones would change condition in the global warming era. The hot surface of waters replaces the natural phenomenon. Warmer oceans mean more intense storms, the number of storms would not rise, but the intensity of the storms would magnify.
These storms would be higher in strength. More people are convinced about this than the number of people who are not confident about this happening.
Clouds are unpredictable when it comes to the global warming of the climate. Warm climates mean more evaporation and hence more clouds. There is a different kind of clouds, and various locations of these clouds, which affect the environment differently. Some clouds change the way that the clouds are affected, and some tap more GHGs. Scientists think that a warmer climate means more clouds.
Climate commitment means the warming that would be taking place because of the GHGs already present in the atmosphere. This is the common phenomenon which is that these GHGs leave the Earth’s body very slowly.
There are certain tipping points which are those greenhouse gas problems which cannot be handled at the last moment. We cannot decide the effect something would have on the climate and especially the exact location and the time when it would happen.
The climate model does not predict when it would rain on March 11 but a question such as the when the next rain would be over NY after ten winters can be judged as per a climate model. The information needed by someone to predict climate changes is parameters such as humidity, air pressure, and wind and so on.
Climate models are not simple, it is many supercomputers running simultaneously, and this is what decides how the climate would change over the decades. Will, there be more carbon dioxide in the atmosphere in a given few years is such things that scientists decide with the help of these supercomputers. The UI of these machines is simple to analyze once all the information is fed into it.
Something which is called the climate time machine looks at parameters of climate change occurring over time. The simple answer to that puzzle is that more fossil fuels we burn, the more climate change would happen. Here is how the decisions of regional, state level, national level, and international level need to be taken.
There are four scenarios. You should eliminate CO2 quick, or somewhat fast, fast or not at all. This, in turn, would affect the predicted sea-level rise. Imagine how far we have come since the 1960s. How many heatwaves there would be each year can also be calculated. Whether there would be more snow and more rain or less rain and less snow also depend on climate change.
The climate change would affect villages, cities, towns, and capitals and no place or location would not bear the brunt of climate change. One hundred million people would get affected. Low lying islands can go extinct and face the biggest brunt of climate change. It is not only significant places which would get concerned, but also highways, airports, railway stations, and sewage treatment plants.
The droughts are going to become warmer and hotter, hurricanes would bring more rain, cyclones would be ghastlier, and floods would engulf more land. There would be deaths by drowning, deaths by burning, and more extreme weather. Agriculture would be affected which means everything would change cyclically.
