The sea ice cover blanketing the Arctic Ocean and nearby seas thickens and expands during the fall and winter each year. It reaches its maximum yearly extent in February or March. This year (2018), on March 17, the Arctic sea ice cover peaked at only 5.59 million square miles (14,478,033.54 km2), the 2nd lowest max on record. It is only about 23,200 square miles (60,000 square kilometers) larger than the record low maximum reached in last year, on March 7, 2017.

Global Sea Level Rise Accelerating, New Study Finds
As a result of the global warming, the seas warm and ice melts. Naturally, Earth’s oceans have risen steadily – or at least, it was thought so. According to a new study based on 25 years of NASA and European satellite data, rather than increasing steadily, global sea level rise has been accelerating in recent decades. If this trend continues, by the year 2100, sea level rise will be around 65 cm (25.6 in), twice as big as previously thought. This is more than enough to cause significant problems for coastal cities.

NASA and NOAA Analyses Suggest That Long-term Global Warming Trend Continued in 2017
According to the analyses of NASA and NOAA (National Oceanic and Atmospheric Administration) data, long-term global warming trend continued in 2017. According to NASA, Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880. NOAA scientists concluded that 2017 was the third-warmest year in their record, in a separate, independent analysis. Both agencies’ records remain in strong agreement: our planet is still getting warmer rapidly. The minor difference in rankings is due to the different methods used by the two agencies to analyze global temperatures. Both analyses also show that the five warmest years on record all have taken place since 2010.

Snow In Sahara, World’s Hottest Desert
On Sunday, January 07, 2018, the residents of Aïn Séfra, a small town in Algeria, experienced a rare phenomenon: snow in Sahara, world’s hottest desert. In the video below, published by the National Geographic, snow dusted the desert’s sandy dunes. With temperatures touching 33.8 degrees Fahrenheit (1 °C), this white blanket stayed briefly through the morning before melting away. However, a few residents found the opportunity to enjoy some winter fun.

Dinosaur-killer asteroid hit “worst possible place”, say Scientists
According to the scientists who drilled into the Chicxulub crater buried underneath the Yucatán Peninsula and the Gulf of Mexico, the asteroid hit the “worst possible place”. They summarized their findings so far in a BBC Two documentary titled “The Day The Dinosaurs Died“. The documentary presented by professors Alice Roberts and Ben Garod.

Watch: International Space Station Passes Over Hurricane Irma
External cameras on the International Space Station captured views during its overhead passes of Hurricane Irma. Most intense Atlantic hurricane observed in over a decade, Hurricane Irma was an extremely powerful tropical cyclone, which became a Category 5 hurricane on September 5. It reached peak intensity with 185 mph (295 km/h) winds on September 6.
