Carbon levels highest in 800k yrs, temp up 1.1°C, Arctic ice melting 12.8% per decade, ocean absorbs 93% heat, methane up 150%, deforestation 10M ha/yr.
6 advanced facts with statistics about how humans are causing climate change for primary 7
1. Carbon dioxide levels are at their highest in 800,000 years: Human activities such as burning fossil fuels and deforestation have caused a significant increase in carbon dioxide levels in the atmosphere. The current levels of carbon dioxide are at their highest in the last 800,000 years.
2. The global temperature has increased by 1.1°C since the pre-industrial era: The increase in greenhouse gases in the atmosphere has caused the global temperature to rise by 1.1°C since the pre-industrial era. This increase in temperature is causing a range of impacts such as melting glaciers, rising sea levels, and more frequent extreme weather events.
3. The Arctic sea ice is shrinking at a rate of 12.8% per decade: The Arctic sea ice is melting at an alarming rate due to the increase in global temperature. The rate of melting has increased in recent years, and the Arctic sea ice is now shrinking at a rate of 12.8% per decade.
4. The ocean has absorbed 93% of the excess heat caused by greenhouse gases: The ocean has absorbed a significant amount of the excess heat caused by greenhouse gases. This has caused the ocean temperature to rise, leading to coral bleaching, ocean acidification, and changes in ocean currents.
5. The concentration of methane in the atmosphere has increased by 150% since the pre-industrial era: Methane is a potent greenhouse gas that is released from sources such as livestock, rice paddies, and landfills. The concentration of methane in the atmosphere has increased by 150% since the pre-industrial era, contributing to the warming of the planet.
6. The rate of deforestation is estimated to be 10 million hectares per year: Deforestation is a significant contributor to climate change as it reduces the number of trees that absorb carbon dioxide from the atmosphere. The rate of deforestation is estimated to be 10 million hectares per year, which is equivalent to the size of Iceland.
