Question

• Greenhouse gases provide some benefits for life on Earth. So why is the greenhouse effect considered a problem?

Answer 1

The greenhouse effect is a natural phenomenon and is beneficial for us. Certain gases in the atmosphere retain part of the thermal radiation emitted by the Earth's surface after being heated by the sun, this maintains the planet's temperature at a level suitable for the development of life. Human action, however, has increased the presence of these gases in the atmosphere  mainly, carbon dioxide and methane , causing them to retain more heat and to increase the temperature on the planet. The increase in the average temperature on Earth is changing living conditions on the planet and result in a following consequences -

Hurricanes will be more devastating
The intensification of the greenhouse effect does not cause these extreme climatic events, but it does increase there intensity. Hurricanes are connected with sea temperature , they only form over waters that have a temperature of at least 26.51 ºC

Desertification of fertile areas
Global warming is having a profound impact on the processes of soil degradation and is contributing to the desertification of the most arid areas on the planet. Desertification destroys all the biological potential of affected regions, turning them into barren and unproductive land.

Migration of species
Many animal species will be forced to migrate in order to survive the changes in the main climatic patterns altered by the progressive increase in temperatures.

Impact on agriculture and livestock
Global warming has already altered the length of the growing season in large parts of the planet. Similarly, changes in temperatures and seasons are influencing the proliferation of insects, invasive weeds and diseases that can affect crops
