  1. The idea of ​​the mechanism of the greenhouse effect was first presented in 1827 by Joseph Fourier. Without the current atmosphere created by the greenhouse effect, the average temperature on our planet would be -15 degrees Celsius.
  2. The natural carbon dioxide content of the atmosphere has varied throughout history between 180 and 300 parts per million (ppm). Today, CO2 levels hover around 380 ppm, 25% more than the highest in the natural environment.
  3. In 1997, atmospheric CO2 increased by 2.87 ppm, an increase greater than in any other year in modern history.
  4. 2005 was the warmest year on record, with 1998 and 2007 taking second place in terms of temperature overall. The eight warmest years in human memory were from 1998 to 2005.
  5. From the bowels of the Earth comes a lot of natural vapors, water vapor, a large amount of carbon dioxide (CO2) and other gases, which, entering the atmosphere, absorb solar energy and radiate it in the opposite direction. This type of warming is called the "natural greenhouse effect". The “greenhouse effect”, in spite of everything else, is causing global climate change due to an increase in the concentration of CO2 in the atmosphere of our planet.
  6. Scientists predict an average global temperature rise of 2.5 degrees by 2100. In the Pliocene epoch (1.8 million years ago), when the Earth's temperature was equivalent to today's, the sea level was 3.5-4.5 meters higher.
  7. Geologists believe sea levels could rise by 20-60 centimeters by the end of the century if current warming trends continue.
  8. The first forced displacements due to the effects of climate change occurred in 2007, when 100 residents of the Pacific island of Tegua were evacuated due to rising sea levels and subsequent flooding.
  9. For the past millions of years, a cool climate has predominantly prevailed throughout the planet. It is believed that it was in these conditions that the human species was able to evolve.
  10. Earth has experienced multiple cyclical changes in climate. Temperature jumps have been recorded throughout the known history of the human race, for example: the Little Ice Age of the seventeenth and eighteenth centuries, the Medieval Warm Period of the eleventh century.
  11. According to NASA research, the average temperature around the world has increased by 1.5 degrees since 1880, while taking into account most of the changes taking place in recent decades.
  12. The Earth experienced two global warming trends throughout the twelfth century.
  13. The first significant increase in temperature peaked between 1900 and 1930, and the second is a constant increase in temperature since the 1970s.
  14. The last two decades of the 20th century have been the hottest decades in over 400 years, and arguably the hottest in terms of temperature for several thousand years.
  15. Mathematical climate models predict that Arctic sea ice will melt earlier and faster than the loss of Antarctic land ice cover, assuming current warming trends continue.
  16. Arctic ice has shrunk by 15% since 1950, and the average annual duration of ice in lakes and rivers in the northern part of the planet has decreased by two weeks.
  17. Arctic ice sheets are disappearing too quickly, and scientists believe the Arctic will begin to show its first soil covers as early as 2040.
  18. Average temperatures in arctic climates in Alaska, Canada and Russia have doubled compared to the global average of the last century.
  19. The effects of global warming could destroy habitats and threaten the extinction of over a million plant and animal species.
  20. Between 1961 and 1997, the world's glaciers lost 890 cubic kilometers of ice.
  21. In 1910, Montana's Glacier National Park had 150 glaciers at its disposal, of which only 27 remain today.
  22. Desert areas around the world are increasing as temperatures rise. At the end of 2007, Australia lost 25% of its harvest due to land desertification.
  23. Swedish scientist Svante Arrhenius realized back in 1896 that human production activity already surpasses the ability of the Earth to naturally absorb carbon dioxide
  24. The burning of fossil fuels currently adds about six billion tons of carbon dioxide to our planet's atmosphere every year. Only half of these emissions are recycled by forests and oceans.
  25. Massive deforestation is responsible for 20% of global warming due to gas pollution, inhibiting the reabsorption of carbon dioxide.
  26. From the first Earth Day in 1970 to the new millennium, human-caused greenhouse gas emissions increased by 70%.
  27. The Earth's atmosphere now contains 40% more CO2 than before the industrial revolution.
  28. The United States has a population of 5% of the global community, but the American nation creates demand for 25% of the world's commercial energy consumption and produces 22% of industrial carbon dioxide emissions compared to the world.
  29. Cars are responsible for 3/4 of all vehicle emissions. At current rates, there will be about 1 billion cars in the world by 2030, and already over a billion in 2050.
  30. About 75% of the annual increase in atmospheric carbon dioxide is the combustion of fossil fuels.
  31. More than 20% of carbon dioxide emissions are generated by gasoline engines in cars. Although the lead in environmental damage is still held by fossil fuel power plants.
  32. A significant increase in CO2 in the atmosphere can certainly increase the temperature, but not so much as water vapor, which accounts for more than 90% of the main components for creating the greenhouse effect.
  33. According to the Internal Energy Agency, the world's richest countries will invest about $ 20 trillion in new energy research over the next 25 years in the hope of slowing the effects of global warming.
