Co2 Levels And Global Warming – Carbon dioxide (CO2) and methane levels in the atmosphere continued to rise in 2020, with CO2 reaching its highest level in 3.6 million years, according to estimates by the National Oceanic and Atmospheric Administration. This barrier was passed despite expected emissions reductions caused by the COVID-19 pandemic.
NOAA reported that average atmospheric CO2 levels reached 412.5 parts per million (ppm) in 2020, an increase of 2.6 parts per million from 2019, the fifth largest increase since atmospheric CO2 measurements began 63 years ago. The increase occurred despite a 7% reduction in global emissions due to the pandemic. Peter Tenes, senior scientist at NOAA’s Global Monitoring Laboratory, believes 2020 would have been a record year if not for the pandemic.
Co2 Levels And Global Warming
The Scripps Institution of Oceanography at the University of California, San Diego released similar findings on Wednesday, saying its measurements showed atmospheric CO2 levels at its monitoring station in Hawaii to be 417.4 ppm. Scripps noted that this raised CO2 levels in the atmosphere 50% higher than they were immediately before the Industrial Revolution.
Ice Cores And Climate Change
Scripps also noted that the amount of CO2 accumulating in the atmosphere is accelerating. “It took more than 200 years for the level to increase by 25%, but now, just over 30 years later, levels have increased by 50%,” the agency said. If current trends continue, CO2 levels are expected to be twice as high as pre-industrial levels in about 55 years.
CO2 is considered a greenhouse gas because of its ability to trap heat. According to a recent study by NASA, greenhouse gases and particulate pollution in the atmosphere caused by the burning of fossil fuels are responsible for most of the warming recorded in the last century.
According to NOAA, the amount of CO2 in the atmosphere now is equal to when the Earth was about 7 degrees warmer than pre-industrial times and sea levels were nearly 80 feet higher than today.
NOAA also found that levels of methane, another greenhouse gas, increased significantly in 2020. “A preliminary analysis by NOAA showed that the annual increase in atmospheric methane in 2020 was 14.7 parts per billion (ppb), the largest annual increase recorded since systematic measurements began in 1983 “, the administration reported.
The Myth Of Co2 Levels And Global Warming
NOAA noted that, as is often the case, this report is preliminary and the final calculation of greenhouse gas levels is generally somewhat lower than previous numbers. It said that, even with the final calculations, “the increase in 2020 is expected to remain one of the largest on record.” The concentration is almost certainly unprecedented in the last millions of years during which modern humans evolved and societies developed. Atmospheric CO
However, the concentration was higher in Earth’s distant past (many millions of years ago), when paleoclimatic and geological data indicate that temperatures and sea levels were also higher than today.
Figure 3. Ice core data used to reconstruct Antarctic temperatures and atmospheric CO2 concentrations over the past 800,000 years. The temperature is based on measurements of the water isotope content of the ice core of Dome C. CO2 is measured in the air trapped by the ice and is part of Dome C and the Vostok ice core. Current CO2 concentration (blue dot) obtained from atmospheric measurements. The cyclical pattern of temperature fluctuations is the ice age/interglacial cycles. During these cycles, changes in CO2 concentration (in blue) closely match temperature changes (in orange). Recent increases in atmospheric CO2 concentrations are unprecedented in the past 800,000 years, records show. The concentration of CO2 in the atmosphere is more than 400 ppm in 2016, and the average concentration in 2019 was more than 411 ppm.

Comparing Co2 Emissions To Co2 Levels
Last approached 400 parts per million about 3-5 million years ago, a time when global average surface temperatures are estimated to have been about 2-3.5 degrees Celsius warmer than pre-industrial levels. 50 million years ago CO
Could reach 1000 parts per million, and the global average temperature was probably about 10 degrees Celsius higher than today. Under these conditions, there was little ice on Earth, and sea levels were at least 200 feet (60 m) higher than today. Ancient air bubbles trapped in ice allow us to go back in time and see what Earth’s atmosphere was like and. They tell us that the level of carbon dioxide (CO
) in the atmosphere are higher than they have been at any time in the last 400,000 years. In the CO ice age
Levels were around 200 parts per million (ppm), and during warmer interglacial periods they hovered around 280 ppm (see fluctuations in the graph). In 2013 CO

Shows a remarkably consistent relationship with fossil fuel burning, and can be well explained on the simple premise that about 60 percent of fossil fuel emissions remain in the air.
Today we stand at the threshold of a new geological era, which some call the “Anthropocene”, an era very different from what our ancestors knew.
If the burning of fossil fuels continues at its normal rate, so that the supply for humanity will run out for centuries to come, CO
Will continue to rise to levels on the order of 1500 ppm. So the atmosphere will not return to pre-industrial levels even tens of thousands of years into the future. This graph not only conveys scientific measurements, but also highlights the fact that humans have a great ability to change the Earth.
