00:00Heat waves in Europe and the United States are breaking old records by big margins.
00:05And even scientists are being caught off guard by the pace of climate change.
00:09The rate of warming has sped up in recent years.
00:11It's not clear exactly what's driving that, but it's affecting every corner of the world.
00:16Ocean temperatures just reached a new high for the early summer.
00:20Satellites are detecting more heat building up in the atmosphere
00:23instead of being reflected back out into space.
00:26And ice sheets and glaciers are melting more quickly than before,
00:29meaning more sea level rise and a weakening of ocean currents.
00:32That doesn't just mean your electricity bill is spiking.
00:36Changes on the ground can be abrupt and dramatic, hurting people and damaging property.
00:41Melting ice sheets are a threat to ports and coasts,
00:44leaving the future of harbours in New York, London and Shanghai unknown.
00:49But at the same time, cheap and plentiful renewable energy is helping to keep global emissions steady.
00:54While that's a reason to be hopeful, it comes a little too late.
00:57A lot of warming is already locked in.
01:00That means a hotter, more extreme future is guaranteed.
01:03The next question is how best to cope.
01:06I'm going to go through my office.
01:06Let's take a moment.
01:06You told me, I saw the task and I'm going to go away.
01:06I'm going to go through my office for a year.
