Frozen Antarctica 37 million years, and is now covered by grasses

Now Antarctica — one of the places on Earth where warming is occurring most rapidly. Before that, for 37 million years, Antarctica cooled. During this period, the temperature there is not increased even once, and only the last 50 years, scientists have observed the reverse process, when the coldest continent was warming up.

This conclusion is a team led by Dr. John Anderson (John B. Anderson) Rice University (Rice University) (Houston, USA) based on palynological studies, ice drilling and seismic measurements in the Antarctic Peninsula — the northern tip of Antarctica.

The history of the continent —

Glaciation makes land vulnerable to repeated offensive ice

Glaciation of some of the land and the appearance of characteristic glacial landforms makes them highly vulnerable to re-attack the ice, which can serve as a reason for even small climate change, climate scientists say in a paper published in the journal Nature.

It is believed that during its existence, Earth has experienced several ice ages, as in the past, at the dawn of life, and more recently — 2.5 million years ago. These events were accompanied by a significant expansion of the polar ice caps and lower average temperatures. Traces of the last glaciation preserved as fjords, hills, drumlins,

Of clean fuel can cause an increase in mortality in the EU by 2020

Increased production of biofuels, which is considered an environmentally clean and renewable source of energy, can 2020 be killing almost 1.4 thousand people in Europe each year and reduce crop yields, Reuters reported with reference to the published in Nature Climate Change report.

"The production of biofuels is a good thing, because it reduces the amount of carbon dioxide (CO2) in the atmosphere. However, this source of energy can affect the air quality. Large-scale production of biofuels in Europe will have a significant impact on mortality, as well as on productivity" — leads Agency words of one of the authors

Climate change will make more ozone is dangerous to plants

Ground-level ozone is a pollutant of the atmosphere, harming both people and plants, and a huge influence on the extent of damage have the climate and weather. Researchers from the University of Gothenburg (Sweden) showed that by the end of the century, climate change can significantly increase the effects of ozone on plants of North and Central Europe.

"The most important effects of rising temperatures — premature aging cultures, resulting in lower yields and quality," — said study co-author Jenny Klingberg.

Ozone — atmospheric gas, located at an altitude of 10-40 km. There, the ozone layer protects

Sea off Antarctica warmed up to the bottom

During the expedition for seven months, scientists have studied the changes in the Southern Ocean. The main conclusion drawn by the oceanographers — poslenie for 26 years in the Weddell Sea deep water warmed even, not just superficial.

May 20 scientific research vessel "Polarstern" Institute for Polar Marine Research Alfred Wegener returned to the port of Bremerhaven (Germany) from an expedition to the Weddell Sea (it is in the Southern Ocean off the coast of West Antarctica). The expedition lasted for seven months, and in the studies involved 200 scientists from 15 countries. Members of the

Season of storms: how not to become a victim of the heavenly electricity

 

According vesti.ru, Rain — not uncommon for the summer in our latitudes. Climate change — in the middle lane in the summer weather, at times, is in the subtropics. And storm warning — not an event for us. How to behave when the gale breaks around the trees, and in the sky and then flashes of lightning? What to do to not get hurt in the storm?

It would seem — walked into the room, and you're safe. Apartment buildings, high-rise buildings in the city, with running water and central heating, well

So fast Greenland is not melting away

Last year, the ice sheet in Greenland melting faster than in the past half century. The National Oceanic and Atmospheric Administration of the United States, reported this in a statement, said that it is one of a number of certainties will climate change. "The world continues to heat up — the scientists say. — No evidence much, one conclusion: a clear and obvious signal from the tops of the atmosphere to the ocean floor."

Annual climate survey, based on the work of researchers from 45 countries, states: never in the history of observations, which began in 1958, Greenland was losing

Climate change is happening too fast

The climate is changing much faster than is the adaptation rights. This imbalance has led to the fact that the temperature increase caused a sharp outbreak of infectious and parasitic diseases in the past two years.

Damage estimated at more than 18 billion rubles. This was stated by the director of the Arctic Institute of Medicine at the SSMU Galina Degteva VII Northern Social and Environmental Congress. This was reported in the press service of the Northern Arctic Federal University (Safa).

Global climate change, according to WHO experts, rather strongly affected is Arctic territory. The climate is changing the

Flood risks in the Russian Federation in the next 5 years there will be more — MES

Russian Emergencies Ministry forecasts the coming five years, growth in the number of dangerous floods and their consequences on the territory of most of the federal districts and global climate change. "By 2015, due to the projected increase in the maximum water storage capacity in snow spring floods may increase in the rivers of the Arkhangelsk region, Komi Republic, the subjects of the Russian Federation in the Ural region, rivers catchment Yenisei and Lena," — told RIA Novosti on Tuesday the head of the Center " Antistikhia "Emergency Situations Minister Vladislav Bolov. He added that at this time "about half

Unprecedented heat in England

The scorching sun in most areas of the UK in the last few days has forced health officials to warn of extreme heat and remind safety rules that must be followed in this weather. The country seems to come abrupt climate change, the day the temperature rises to 33 ° C, it is even higher than in Miami and Barbados, and experts believe that the hot summer weather may persist for at least another five years.

Meanwhile, thermometers such hotspots Caribbean such as Miami and Florida, show only 29 ° C. But meteorologists also predicted heavy rain and thunderstorms in
