May 25, 2015 · To put 400 ppm in perspective, consider that maximum pre-industrial CO2 levels were 280 ppm and that 350 ppm is widely considered the upper limit to avoid truly dramatic climate change. Consider that CO2 levels haven’t been as high as 400 ppm in several million years, when the world was much hotter and the oceans much higher than they are today.
May 05, 2021 · The graphs show monthly mean carbon dioxide measured at Mauna Loa Observatory, Hawaii. The carbon dioxide data on Mauna Loa constitute the longest record of direct measurements of CO 2 in the atmosphere. They were started by C. David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and Atmospheric Administration [Keeling, 1976].
99% of the solution must be to extract CO2 from the atmosphere and it must be if full operation 2025. Otherwise the Paris agreement will collapse. The mathematics behind this fact is very simple. If we choose to build the climate politics on truth we can make a quality job with the climate.
Dec 18, 2007 · CO2 levels in the atmosphere today are NOT at record high levels. Carbon dioxide is such a small component of Earth’s atmosphere (380 parts per million or 0.038%) that it shows up on the chart below as only a thin line (shown at 2x actual thickness, just so you can see it!). Compared to former geologic times, Earth’s atmosphere is “CO2 impoverished.”
Mar 29, 2019 · About 3 million years ago, horses and camels roamed on what today we know as the icy high Arctic region. In 2013, an instrument in Hawaii recorded a milestone we haven't seen since that period: the amount of carbon dioxide (CO2) in the atmosphere there exceeded 400 parts per million (ppm) for the first time since it began to be measured 55 years before.
Today, we stand on the threshold of a new geologic era, which some term the "Anthropocene", one where the climate is very different to the one our ancestors knew. If fossil-fuel burning continues at a business-as-usual rate, such that humanity exhausts the reserves over the next few centuries, CO 2 will continue to rise to levels of order of 1500 ppm.
