What is global warming?

Global warming is an increase in the average temperature of the atmosphere near the earth’s surface and oceans observed since the mid-20th century, simultaneous cooling of the stratosphere and the expected future warming resulting from the Earth’s radiation imbalance.


Global warming definition

Global warming is an increase in the global average temperature of the Earth. According to the IPCC Fifth Report of 2013, the global average surface temperature of oceans and land areas increased in the period 1901-2012 by approximately 0.89 ° C. The increase in temperature is probably the result of a higher than in the industrial era of reverse radiation of the atmosphere, and it is currently estimated that 80% of carbon dioxide emitted by humans is responsible for this additional stream of returnable radiation.


Causes of global warming

Human activity – burning fossil fuels, cutting down rainforests or farming livestock – has an increasing impact on the climate and temperature on Earth.

As a result, the amount of greenhouse gases naturally occurring in the atmosphere greatly increased, and this has increased the greenhouse effect and global warming.


Consequences of global warming

It would seem that increasing the average temperature just by a few degrees Celsius would not have a greater impact on the climate, but it can have a number of different effects.

It is obviously very difficult to properly predict them and you may come across conflicting information. However, over time, scientists are able to better interpret facts and forecast events that could happen. Here are some of the most important changes that global warming can cause:

* Raising the sea and ocean level from 9 cm to 88 cm by 2100. Such an increase in water levels can cause floods during storms and storms, seasonal flooding, and in some regions, total flooding (Florida peninsula, San Francisco Bay region, the Netherlands, and Beijing) .

* Unprecedented drought and hot weather can cause water shortages, fires and the deaths of tens of thousands of people (such as during the heat wave in Europe in 2002). Paradoxically, at the time of drought and hot weather, in other regions there may be unusual storms, rainfall and mudslides.

* Decrease in the population of some plants and animals. In some cases, an increase in temperature can cause the extinction of some species of fauna and flora that will not be able to adapt to climate change.

* The threat of diseases transmitted by mosquitoes, insects and rodents in regions where previously these diseases were unheard of.


Global warming and climate change

Global warming is “An overall increase in world temperatures which may be caused by additional heat being trapped by greenhouse gases.”

That means, the increase in the average temperature of the Earth, which may be the result of the inflow of additional heat captured by the greenhouse gases to the Earth.

The greenhouse effect, as we already know, is to raise the Earth’s temperature compared to the lack of greenhouse gases in the atmosphere, and global warming is an increase in the global average temperature of the Earth, in the period after the industrial revolution in the world, caused (probably) to intensify the natural process (i.e. greenhouse effect) by human activity (ie by the emission of large amounts of greenhouse gases into the atmosphere).
