Surprise: The Last Ice Age was colder than anyone thought. Blame CO2! W e panic about the next half degree of warming (above the we’ve already had) but the depth of the ice age was savagely cold. For years the experts told us what Earth’s temperature was then, but apparently they were wrong. And yet corals and rainforest survived.
Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000. So. 1ppm = %. So to convert from ppm to percent, divide the ppm by 10000:
CO2: 0 to 2000, 0 to 5000, or 0 to 10000 ppm (depending on model). Accuracy: CO2: ±40 ppm ±3% of reading. Temperature Dependence: ±8 ppm/°C at 1100 ppm. NonLinearity: 16 ppm. Pressure Dependence: % of reading per mm of Hg. Response Time: 300 s (T63). Temperature Limits: 32 to 122°F (0 to 50°C). Humidity Limits: 10 to 95% RH ...
