What pattern do you observe between CO2 and temperature? What evidence is there to support?
Over the past century, there has been a significant relationship between global temperatures and atmospheric carbon dioxide (CO2) concentrations. Global temperatures have risen along with CO2 levels as a result of human activities like burning fossil fuels and deforestation.
The warming of the climate system is mostly caused by greenhouse gas emissions, according to the Intergovernmental Panel on Climate Change (IPCC), which has declared that there is conclusive evidence for human-induced climate change. The IPCC has also discovered that human activities, such as the burning of fossil fuels, are to blame for the rise in atmospheric CO2 concentration since the pre-industrial era, which is warming the planet's climate.
Ice cores are one source of data supporting the link between CO2 and temperature. Drilling deep into ice sheets allows scientists to retrieve long cylinders of ice that contain air bubbles from tens of thousands of years ago. Scientists can ascertain the atmospheric CO2 content and temperature at the time the air was caught by examining the makeup of these bubbles. According to this data, CO2 levels and temperature have been rising and dropping in a pattern that is tightly associated for at least the last 800,000 years.
Direct observations of atmospheric CO2 concentrations and global temperature records provide additional proof. Since accurate measurements of the atmospheric CO2 concentrations started in the 1950s, levels have continuously increased from about 315 parts per million (ppm) to over 400 ppm at this time. Global temperatures have also increased by roughly 1°C (1.8°F) throughout the same time period. There is no other known mechanism that might account for the observed warming because of the tight link between these two trends.
