Sea level rises to these high values will take many centuries, or even millennia, but the implications from the geological record are clear - for a future climate with maximum warming of about two degrees Centigrade, that is with CO2 stabilized at 400 to 450 parts per million
, sea level is set to steadily rise for many centuries, towards its natural equilibrium position at around 24 +7/-15 metres, at 68 per cent confidence," Rohling said.
The theories say a star like Procyon should exhibit brightness variations amounting to 60 parts per million

In measuring solids such as plastic pellets and thin films, XRF has the same detection sensitivity - down to a few parts per million
- as classic elemental analysis techniques such as atomic absorption spectroscopy, which require samples to be dissolved in a solvent before they can be analyzed.
