It's one of the most powerful forces warming the Earth, leading to increasingly severe droughts, wildfires and floods. It's also invisible. So how do we see start seeing carbon?
He grabs air samples in two separate ways. The first is by hand, capturing air in pressurized bottles on a weekly basis that are sent to a lab in Colorado for analysis. The second is from a tower that is another 140 feet up. It pulls and analyzes samples on site, 24 hours a day, with hourly findings published online.
By going back 800,000 years and studying things like ice core samples, ocean sediment and tree rings, scientists have a good idea how much carbon has historically been in the Earth's atmosphere. Carbon dioxide levels go up and down over time, but they never went higher than 300 parts per million. "The CO2 in the atmosphere has never been seen this high in human history," said Colton.
"We're moving through the streets," said Herzl."That enables us to pinpoint the precise location of those measurements." , the number one source of carbon emissions is transportation, at 27% of greenhouse gases. "We're trying to get an idea of how this greenhouse effect works," said Cordero."How does CO2 have this power over controlling the Earth's temperature?"In the experiment, the candle represents the heat of Earth.A piece of glass in a picture frame represents carbon dioxide, which Cordero said acts in a similar way.
