and carbon dioxide (CO2) and include a variety of other gases with middle of this century, a concentration of between 450 and 500 ppm can

In general - ventilation rates should keep carbon dioxide concentrations below 1000 ppm to create indoor air quality conditions acceptable to most individuals. Se hela listan på climate.gov CO2.Earth förbinder allmänheten med de senaste uppgifterna och informationen för att stabilisera jordens atmosfär, klimat och levande miljöer. CO2 concentrations in 2020 would be about 410 ppm (and rising over 2 ppm a year). Around 2050, we’d be at 5 billion tons and very likely over 450 ppm, rising over 1 ppm a year. 2019-05-14 · CO2 levels are now rising 3 ppm each year, up from an average 2.5 ppm over the last decade, the scientists said.

At the time, atmospheric CO2 concentration was at a whopping 3000 to 9000 ppm!

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. For example, in a space of about 4 m 2 occupied by only one person, the CO 2 value rises from 500 ppm (0.05%) to more than 1,000 ppm (0.1%) in just 45 minutes. At this level, the odorless and colorless gas can cause headaches, drowsiness, and poor concentration, often resulting in reduced productivity.

At the current rate of growth in CO2, levels will hit 500 ppm within 50 years, putting us on track to reach temperature boosts of perhaps more than 3 degrees C (5.4 ° F) — a level that climate scientists say would cause bouts of extreme weather and sea level rise that would endanger global food supplies, cause disruptive mass migrations, and even destroy the Amazon rainforest through drought and fire. Recent studies which correlate atmospheric CO2 levels with the appearance and disappearance of the polar ice sheets, define thresholds at levels no higher than about 500 parts per million CO2 — within the range of the Garnaut report’s alternative targets of 450-550 ppm. Most experts have maintained that a doubling of CO2 (near 500 ppm) is a dangerous territory.
