They are often used as synonyms in a wrong way, the terms climate change and global warming when they mean two completely different things. It is clear that the two concepts refer to the havoc it is suffering all the planet due to the hand of man and those who must remedy quickly.
I will explain clearly below what does each term consist of so that it is clear to you.
When experts use the term climate change, refer to significant changes in the climate that affect aspects such as temperature, rainfall or wind and that occur for several decades. By contrast, global warming refers to the continuous rise in the average temperature throughout the planet.
This warming is caused by concentrations of greenhouse gases that is in the atmosphere and in itself is nothing more than an aspect of called climate change.
There is no doubt that climate change it's a real real problem and that the entire planet is warming by leaps and bounds. According to some reliable data, the average temperature of the planet has risen more than 7 degrees throughout the last century. Scientists predict that the average temperature will increase by 1.1 degrees to 6.4 degrees throughout the XNUMXst century, these are really worrying data that will cause very dangerous changes in the weather.
These negative effects of climate change occur every day and in any area of the planet. In many places the rains have increased and caused flooding, while in other regions of the Earth, on the contrary, there have been severe droughts . Heat waves during the summer months are more and more frequent, causing a greater number of deaths and a greater number of forest fires.
Hello, good note, I just think you make a mistake when you say that the temperature has increased 7 degrees in the last century, the correct thing would be 0.7, I leave you this link that may be useful.
