Interesting graph. Caused by humans/fossil fuels/the Sun? What do you think? Does it show a trend? Is it a misleading graph? If so, why?

Some climbers call heights over 8000 metres, “The Death Zone”. Above this altitude it is difficult to sleep and impossible to eat enough to maintain body weight. No one can survive at this extreme height for more than a few days.
There are only 14 mountains that reach this height, all in Pakistan and Nepal.

The Steepest Street in the World
Dunedin, in New Zealand, claims to have the world's steepest paved road. However some people challenge Baldwin Street's slope and say mapping error has given it a gradient of 1 in 2.66, or 38%. However, it is almost impossible to ride a bike up or down it. Many of the stiffest road climbs for cyclists are on the Austrian side of the Dolomites (Halltall rises to 1482m in 7km at an average of 14%, its steepest stretch being 32%).
In France from the top of the legendary 1909m Mont Ventoux, there's around 1500m of descent in 21km averaging 7.5%; Iseran's 2770m peak offers 37km of descent and Alpe d'Huez has 21 hairpins.
San Francisco in the USA has some seriousoly steep streets. Take Lombard Street, a short streetcar ride from Fisherman's Wharf. This tourist photostop appeared for years in the Guinness Book of Records under its 'steepest street' entry, despite not even being the steepest street in San Francisco. At 1 in 5.5, or 18%, it's a mere slope compared to neighbouring Filbert St, San Francisco's actual steepest at 1 in 3.2, or 31.5% (22nd St is also 31.5%).
So it looks like Baldwin Street (pictured) may be the steepest after all.
