Yes, they are lovely trees, but if they are looking at the world's biggest trees, I wonder why the ancient kauri tree known as Tane Mahuta, king of the forest, in North Island, NZ, wasn't included. This tree has reached the age of 1500 years, is more than 51 metres high and has a girth of 13.7 metres. Kauris have been cut down in the past for building Maori canoes and homes; and by European newcomers for the timber trade. Now the emphasis is on conservation.
That looks like a series of the clouds called "Morning Glory" that were shown on QI the other night. In that case it was just one rope of cloud which stretched for miles and was a regular tourist attraction in a little town at the back of beyond. Must be a result of the landscape and the wind patterns.
Just for balance to the misinformation published with the second of the images (that of the McClure Strait which the blurb says has been fully open since 2007), here is an up-to-date image of the state of Arctic sea ice from the National Snow and Ice Data Center.
Methinks they missed out an important phrase from the blurb, one saying that the McClure Strait "has been open for a short period at the end of summer each year since 2007" before it freezes up again for the winter. Just for balance, it's important to remember that it had been open in some summers before that too.
I bet you watch this more than once ...make sure you have the volume up too ...I love the sound track that goes with it...and if you click on the image it will go full screen. enjoy
