Here is the text that goes with the chart:
The new data, compiled from more than 3,000 measuring points on land and sea, was issued quietly on the internet, without any media fanfare, and, until today, it has not been reported. [My bolding]
Had the reverse been the case, the news would have, of course, been front page and top of the bulletin across the world. If we had been worrying about being hit by a meteorite, the whole world would have been in collective relief that we had escaped. Not with this. Here we are dealing with people with other agendas running, not just a selfless desire to save the planet from a rise in temperature. Without the data to support them, those agendas will not go away, but it will be harder to make the case given just how contrary to the facts the global warming argument has become.
