And we seem to think we're top of the pile.

We're not.

90% of our cells, by number, are bacteria.

15% of our weight is bacteria.

If you want to die, a good bacterial infection will do it.

The dominant life form on Earth are not wilds, they're not trees, they're bacteria.

And most of them are beneath your feet for the top four kilometres in the crust.

So we tend to think we're pretty important.

We're not.

Well, two things.

The records haven't been around that long and the temperature record is a contaminated record.

These have a cluster of measurements in the UK, Europe and the US.

These were, many of them were in rural areas, which are now in cities and suburbs.

And so you have the urban heat island effect.

And these figures are changed.

So the primary data is changed.

And often you see that in a rural area, when it's been changed, it gives a warming trend.

So I think the data is contaminated.

And a number of people have commented on that, including people at climate institutes like your Phil Jones.

You've got to be very careful of the records.
