Climate change deniers like to argue that our planet would warm up no matter what, even without the greenhouse gas emissions that humankind is releasing into Earth's atmosphere.
Maliverno, however, says that the geological record doesn't suggest that this would be the case.
"There have been several campaigns in the past when researchers drilled into the Antarctic ice sheets and took samples from deep below the surface, reaching layers that are up to 800,000 years old," Maliverno said. "They analyzed the concentrations of carbon dioxide trapped in those layers. There are tiny air bubbles in the ice, essentially samples of the atmosphere as it was back then, and they found that even during the interglacials, the maximum amount of carbon dioxide was nowhere near the amount that we see today."
Moreover, Maliverno added, computer modeling studies that tried to reproduce the current climate change using only natural variables, such as the Milankovitch cycles, couldn't match the rate of warming we see today.
I didn't reply with that information for your benefit. I replied to add context for other readers.
Either you have a specific claim against this publisher, article, or point or you don't. This is a respected science oriented publisher with interviews of scientists talking about their research in their own field.
When? When the indicators tell you that the CO2 is high. CO2 monitor is also used in industrial processes where ventilation is difficult and equipment is heavy. The monitor tells you when to leave the area.
Your question is irrelevant. The article wants to address climate change, not indoors: "This breakthrough addresses a critical need in environmental monitoring: accurately understanding "how much" CO2 is being emitted to combat climate change and global warming."
Looks like you still don't get it. The article had zero intentions to talk about indoors, and you think it's my fault, because you asked "You do realize that indoor air quality is also a thing, right?" Whatever the spirit of HN is, it would be rude to dismiss my comment just because I talked specifically about the claim of the article, which is global warming in general. If you want to talk about indoors, do it in a different thread, and stop bullshitting me. You have only been inappropriate and rude to me.
