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.

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.

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.

Today, on January 4, 2018, NASA has published an amazing GeocolorNotes 1 image of so-called “Bomb Cyclone”, a very powerful storm off the East coast of the United States. It was taken from National Oceanic and Atmospheric Administration (NOAA) GOES-16 satellite (previously known as GOES-R).Notes 2

The US government keeps a massive archive of ancient ice inside the National Ice Core Laboratory (NICL) in Denver, Colorado. This ice could hold important information about Earth and its climate.

According to the scientists who drilled into the Chicxulub crater buried underneath the Yucatán Peninsula and the Gulf of Mexico, the famous dinosaur-killer 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.

External cameras on the International Space Station captured views during an 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.

Our civilization emit so much CO2 into the Earth’s atmosphere, that only planting trees is not enough, according to a new study.

Have you ever wondered what would Antarctica look like if all its ice melted? This may seem extraordinary and unlikely, but, this has actually happened in the past. In fact, there have been no major ice sheets over the South Pole for most of the Earth’s history.
In the video below, NASA Goddard strip away Antarctic ice to reveal a new, and much more detailed map of the bedrock below. This map, called Bedmap2, was compiled by the British Antarctic Survey and incorporates millions of new measurements, including substantial data sets from NASA’s ICESat satellite and an airborne mission called Operation IceBridge.
