causes of climate change

 Climate change refers to long-term changes in temperatures and weather patterns.

These changes may be natural, but since the 19th century, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels, such as coal, oil and gas, which produce gases that trap heat. . If the current rate of emissions continues, extreme heat waves will become more frequent. This could lead to a 4-fold increase in heat-related deaths, with more than a third of the population experiencing water shortages with 2°C of warming; double if 3°C is reached. This would lead to greater economic losses in the sectors dependent on water and energy; Analyzes show that by 2050, unless global emissions are significantly reduced, ecosystems such as posidonia marina meadows in the Mediterranean will become extinct.
