#40- Huge Iceberg ready to clave away from ANTARTICA


We're nearly observing one of the ten biggest ice shelves ever recorded, by from Project Midas, entrusted with checking a crack in Antarctica's Larsen C ice rack (BBC). The break all of a sudden developed by 18km through the span of two weeks in December, and now just 20km of ice holds a 5,000 square kilometer area of ice to whatever remains of the rack. The Swansea-based Project Midas group caution that the loss of such an expansive lump of ice will put the whole Larsen C rack at danger of separating.

An iceberg that would be one of the 10 biggest ever recorded is prepared to split far from Antarctica, researchers say.

A long-running break in the Larsen C ice rack developed all of a sudden in December and now only 20km of ice is keeping the 5,000 sq km piece from skimming without end.

Larsen C is the most northern real ice retire in Antarctica.

Specialists situated in Swansea say the passing of a piece a fourth of the measure of Wales will leave the entire rack defenseless against future separation.

Larsen C is around 350m thick and buoys on the oceans at the edge of West Antarctica, keeping down the stream of ice sheets that nourish into it.

Analysts have been following the fracture in Larsen C for a long time, watching it with some fear after the crumple of Larsen An ice retire in 1995 and the sudden separation of the Larsen B retire in 2002.
A year ago, specialists from the UK's Project Midas reported that the Larsen C crack was developing quick.

Be that as it may, in December the speed of the break went into overdrive, developing by a further 18km in only two or three weeks. What will end up being a monstrous icy mass now clings to the rack by a string only 20km long.

"This iceberg will change the landscape there."

#29- 2016-The Year in Climate Change


2016 burned through heat records, and the year is poised to be the hottest year since recordkeeping began 122 years ago, by a significant margin. At only the halfway point of 2016, NASA had announced that each of the first six months (from January to June) set new temperature records. Also, July and August were tied as the hottest month the world has seen in the last 136 years. By November, global temperatures had averaged 2.2 degrees Fahrenheit (1.2 degrees Celsius) above pre-industrial levels, according to the World Meteorological Organization. The Copenhagen Accord in 2009 stated that warming should not increase by more than 2 degrees C (3.6 degrees F) this century, to hopefully avoid the worst impacts of climate change.

  • Scientists predicted that this year the global atmospheric carbon dioxide concentration would pass the 400 parts per million mark, permanently. In September, a month when carbon dioxide is typically at its lowest, the monthly value failed to drop below 400 ppm for the first time. The 400-ppm milestone is largely symbolic, a sign of modern civilization's devastating impact on the planet, climate scientists have said. Since the industrial revolution, humans have been adding more carbon dioxide to the atmosphere than plants can take up. This process has driven carbon dioxide levels higher, adding to the greenhouse gas effect and increasing temperatures, along with many other climate change impacts.
  • The report found that in 2016 ice levels showed the strongest, most pronounced signal of persistent warming due to climate change. In fact, the Arctic has continued to warm at twice the rate of the planet as a whole. With winds pulling warmer air up from the south, some areas of the Arctic experienced temperatures 14 degrees F (8 degrees C) above average this year, according to the Arctic Report Card.

#11 Global Warming: News, Facts, Causes & Effects


Global warming is the term used to depict a steady increment in the normal temperature of the Earth's environment and its seas, a change that is accepted to be forever changing the Earth's atmosphere. There is awesome verbal confrontation among many individuals, and now and again in the news, on whether a dangerous atmospheric devation is genuine (some call it a deception). However, atmosphere researchers taking a gander at the information and realities concur the planet is warming. While many view the impacts of a dangerous atmospheric devation to be more considerable and more quickly happening than others do, the logical agreement on climatic changes identified with a worldwide temperature alteration is that the normal temperature of the Earth has ascended somewhere around 0.4 and 0.8 °C in the course of recent years.
