Climate change goal ‘unreachable’

In public, climate scientists and European politicians are generally optimistic that rising carbon dioxide levels and temperatures can be curbed.

In private, some are less sanguine; but there has been a widespread unwritten code of optimism to avoid being accused of scaremongering or creating despair.

Now, science advisors to two governments with claims to leadership in global climate politics, Germany and the UK, have told BBC News it is unlikely that levels of greenhouse gases can be kept low enough to avoid a projected temperature rise of 2C (3.6F).
