how to calculate ppm for co2 of in ocean

There are a variety of reasons, some more obvious than others. So why does it matter when we hit a new CO2 milestone? And why monitor carbon dioxide concentrations instead of just paying attention to global temperatures? Same when nations experience their hottest heat waves or when winter temperatures are the highest ever recorded. It’s major news when yearly or monthly temperature records are broken. World nations participating in the Paris climate agreement have chosen to set their goals in terms of global temperatures, aiming to keep the climate from warming more than 2 degrees Celsius, or 1.5 C if possible, above its preindustrial condition.Īnd, indeed, global temperature milestones may make even bigger headlines when they occur. But it’s the warming, itself, that often captures the most international attention. The last time CO2 concentrations hit 415 ppm was likely close to 3 million years ago.Ītmospheric CO2 levels are directly correlated with rising global temperatures. Every year, the world sees new levels that were previously unrecorded in modern human history. Atmospheric CO2 is rising at accelerating rates-currently climbing at close to 3 ppm each year, and getting faster. It’s the latest in a long list of broken records, and like the others, it promises to hold the title temporarily.

Another climate milestone soared by last weekend when scientists announced that atmospheric carbon dioxide levels hit 415 parts per million for the first time ever ( Climatewire, May 7).
