In recent decades, climate change on the planet has become evident. The state of the climate directly affects the lives of all inhabitants of the Earth. Climate scientists have found a correlation between the impact of human activities on changing weather patterns and the resulting global warming. Economic calculations show that if the rate of growth of modern energy, based on the burning of fossil fuels, continues in the future, the climate of Earth will change in the direction of warming. Therefore, the problem of a warming climate on our planet is extremely urgent.
It is generally known that the average annual air temperature is steadily rising. Its increase is estimated at 0.7. °С for 100 years. Warming is accompanied by some negative phenomena: more frequent floods, hurricanes, problems of desertification. These problems harm both the nature and the man. Therefore, it is important to know how the climate will change in the future, what negative consequences can expect us in the future. Till now scientists cannot say with 100% certainty what causes climate change. Many theories and assumptions are put forward as causes of global warming.
The benefits of global warming
- Cold regions may become more vegetated.
- There won’t be a second Ice Age.
- Less energy will be needed for space heating.
- There will be fewer deaths from frostbite.
- The growing season of plants will be longer, which will increase crop yields.
Negative aspects of global warming
- Deserts will increase, rivers will dry up and millions of people will be doomed.
- The circulation of the world’s oceans will be disrupted, with irreversible consequences for the climate.
- Chronic diseases at people will aggravate, animals will die.
- Storms and other natural cataclysms will occur more often.
- If less energy is used for heating, more will be used for cooling.
Climate change, along with other natural and anthropogenic factors, has a variety of effects on human health and disease. Some existing health threats will increase, and new threats will arise. Not all people are equally at risk. Important factors include age, economic resources, and location. The health of populations can be affected by the destruction of physical, biological, and ecological systems.
