Offbeat A third of the glaciers of the world heritage will have disappeared by 2050. A third of the approximately 50 UNESCO World Heritals with glaciers will probably have disappeared by 2050, including the Kilimanjaro and Yellowstone.
Why two Indians disappeared on a July night in Kenya
Two Indians vanished in Nairobi in July. Officials now suspect they were abducted by rogue policemen.In one of his last social media posts before he disappeared, Zulfiqar Ahmad Khan shared a video of a roaring lion in Kenya's Maasai Mara game reserve where he had been holidaying.

50 UNESCO World Heritals Hergen Glacier (a total of 18 600 glaciers with an area of around 66,000 km2 were identified in these 50 sites), which corresponds to almost 10 % of the total glacier area of the earth. These include the highest (in addition to Mount Everest), the longest (in Alaska) and the last remaining glacier in Africa, which gives a representative overview of the overall condition of the glaciers in the world.
Kampung Baru survives as a slice of village life in the middle of one of Asia's biggest cities
As our world becomes increasingly urbanised, cities have all begun to look the same. There are some exceptions — but are we about to lose them too?He's lived all his life in a traditional Malay village called Kampung Baru, which means "new village", but he considers himself a city boy.
The new UNESCO study, which was carried out in cooperation with the IUCN, shows that these glaciers have been faster and faster since 2000 due to CO2 emissions that lead to an increase in temperatures. They now lose 58 billion tons of ice cream every year, which corresponds to the annual water consumption of France and Spain, and are responsible for almost 5 % of the observed global sea level increase.
The report comes to the conclusion that the glaciers will disappear in a third of the 50 World Heritage Sites by 2050, regardless of the effort to limit the rise in temperature. In the remaining two thirds of the areas, however, the glaciers can still be saved if the temperature increase is no more than 1.5 ° C compared to pre -industrial times.

In addition to a drastic reduction in carbon emissions, UNESCO is committed to the establishment of an international fund for monitoring and maintaining the glaciers. Such a fund would support comprehensive research, promote the exchange between all participants and implement measures for early warning and disaster prevention, explains the UNESCO in an explanation.
Half of humanity depends directly or indirectly on glaciers as a water source for household, agriculture and energy. Glaciers are also pillars of biological diversity and supply many ecosystems.
On the basis of the available data, the UNESCO report determines that the glaciers will probably disappear in all world sites in Africa by 2050, including the glaciers in Kilimanjaro National Park and on Mount Kenya. In Asia, the glaciers stand out in the three-parallel flows of protection in Yunnan (China), which have the highest mass loss (57.2 %) compared to 2000 and also melt the fastest. In the study, the glaciers in western Tien-Shan (Kazakhstan, Kyrgyzstan, Uzbekistan) are also called 27 % since 2000.
In Europe, the glaciers in the Pyrenees of Monte Perdido (France, Spain) will most likely disappear until 2050, as well as the glaciers in the Dolomites (Italy).
In Latin America, the glaciers in the Los Alerces (Argentina) National Park have the second highest mass loss since 2000 (45.6 %), and the glaciers in the Huascarán National Park (Peru) have shrunk by 15 % since 2000.
in North America is very likely that the glaciers will disappear in the Yellowstone National Park and in the Yosemite Park by 2050.
The world has reached 8 billion people — but soon we'll hit a decline we'll never reverse .
This week, the world's population ticks over a historic milestone. But in the next century, society will be reshaped dramatically — and soon we'll hit a decline we'll never reverse.We never know precisely how many of us are alive at any one time, but this Tuesday is the United Nations’ best estimate on when we’ll reach 8 billion human beings.
