(CNN)The Paris climate talks hope to set out how we can reduce the amount of carbon we're pumping into the atmosphere. But emissions cuts alone may not be enough. Atmospheric CO2 is the blanket that keeps our planet warm and any further emissions will mean more global warming. Observations in recent years show that warming is accelerating, that polar ice and glaciers are all melting, that sea level is rising ... it all looks rather bleak.
