Himalayan forests burned by fires: especially in the state of Uttarakhand in India's Himalayan region. Wildfire intensifying in April as northern India enters its hot, dry summer, reports the Financial Times. Scientists say the driest winter of the past decade has worsened the situation in the mountains.
Nepal is also faced with a serious series of fires, to the point that the capital Kathmandu is enveloped in smog caused by the fires. Experts told: "Forests are our main resource. If we lose them it will be a loss not only for our state, but for all of India and for the world.
We are degrading the natural environment. There are fewer and fewer places that we can define as wild."
Fossil Vegetation under Greenland ice!
Incredible discovery made on the largest frozen island on the planet: Geologists have discovered that at Camp Century in Northwest Greenland, the ice has completely melted at least once in the last million years.
And the landscape was completely different from today's frozen wasteland: there were mosses and trees there, according to paper published in Proceedings of the National Academy of Sciences. Andrew Christ, a research fellow in the Department of Geology at the University of Vermont, said: "The subglacial sediments from the Century Camp ice core were collected in 1966.
The sediments were stored frozen, initially at the University of Buffalo since. 1966, until they were transferred to the Niels Bohr Institute in 1994 and 1996. We used a number of advanced analytical techniques, none of which were available to researchers 50 years ago, to examine the sediments, fossils and coatings of leaf wax at the bottom of the Horn Ice Camp core.
We measured the rare isotope ratios for aluminum and beryllium, which forms in quartz only when the Earth is exposed to the sky and can collide with cosmic rays Normally, ice caps crush and destroy everything in their path.
But what we discovered were delicate structures of vegetation, perfectly preserved or fossils, but it looks like they died yesterday. It is a time capsule of what lived in Greenland and we will not be able to find anywhere else.
Another test used rare forms of oxygen, found in the ice within sediments, to reveal that precipitation must have decreased at altitudes well below the current ice sheet height, indicating the absence of ice cover. Our study shows that Greenland is more sensitive to natural climate warming than we thought and we already know that global warming beyond human control is well above the natural range."
