Because the heat on the planet increases every year, according to NASA

Global warming is advancing and the countries of South America are going through a crisis phase a significant heat wave during the summer monthswhich causes forest fires, extreme temperatures and air degradation.

This is due to climate change, which intensifies every year. Since the 19th century, human activities have driven changes in the burning of coal, gas and oil, increasing the concentration of atmospheric carbon dioxide (CO2) and thus causing the expansion of the greenhouse effect.

Why is global warming getting worse every year?

According to a report from JAR, human activities have caused an expansion of the greenhouse effect, the warming that occurs when the atmosphere traps heat radiated from the Earth into space. Greenhouse gases they absorb that heat which should be expelled and re-radiate it, causing the planet to warm.

The five gases that have caused climate change on the planet, according to NASA:

• Carbon dioxide. Since the industrial revolution there has been a 50% increase in this gas, which is released by natural processes or human activities, such as fuel combustion and deforestation.
• Methane. This is a natural, colorless, odorless gas produced by the decomposition or digestion of organic matter. Methane is less common in the atmosphere, but its quantities have increased since pre-industrial times.
• Nitrous oxide. This colorless gas is released during the production and use of commercial and organic fertilizers, although it can also come from the burning of fossil fuels and vegetation.
• Chlorofluorocarbons (CFCs). It is used in the refrigeration industry and as a propellant for spray cans. Emissions of this compound were reduced in 2018, when an international agreement called the Montreal Protocol began regulating ozone-depleting substances.
• Water vapor. While this gas is not a direct cause of climate change, water vapor in the atmosphere responds to Earth’s warming, amplifying climate change.

In summary, the increase in carbon dioxide, nitrous oxide and methane since the industrial era “is the result of human activities, and human influence is the primary driver of many changes observed in the atmosphere, ocean , in the cryosphere and in the biosphere”.

Meanwhile, NASA has come to the conclusion that solar radiation was one of the causes of climate change in the past, but that this influence cannot be attributed to it in the last century.

“Since 1750, the average amount of energy coming from the Sun has remained constant or slightly increased,” they clarified.
