Most species hold their geographic range if we limit global warming to 1.5°C, study says

If we limit global warming to 1.5°C rather than 2°C above the pre-industrial levels by the year 2100, the impacts of climate change would be much less dramatic, a new study says. According to the researchers, for vertebrates and plants, the number of species losing more than half their geographic range by 2100 will be […]

Atmospheric Carbon Dioxide Reached the Highest Levels in 800,000 years

According to measurements from Mauna Loa Observatory in Hawaii, with 410.31 ppm (parts per million), the level of carbon dioxide in Earth’s atmosphere hit a new high in April 2018. This is the highest point for the last 800,000 years. Last year’s (April 2017) value, 409.00 ppm, was also a record high. As you can […]

What Would Happen If the Earth Started Spinning Backward?

The dynamics of the ocean and the atmosphere are strongly influenced by the Earth’s rotation. Currently, our planet rotates from west to east (prograde, which appears counterclockwise) with a linear velocity of 465.1013 m/s (1674.365 km/h or 1040.40 mph) at the equator. What would happen if the Earth started spinning backward (from east to west)?

Global Warming: Future greenhouse gas emission scenarios

The future of our carbon dioxide and greenhouse gas emissions will decide how many degrees will planet Earth be warmer by 2100 (relative to pre-industrial temperatures). Using the data from Climate Action Tracker, the online publication that shows how living conditions are changing, Our World In Data has published a chart showing future greenhouse gas […]

You can help NASA on some projects: for instance, citizen scientists helped NASA identify an aurora-related celestial phenomenon, now called STEVE. Want to become a citizen scientist? You can find projects on the NASA website.

Watch: Iceland Is Growing New Forests for the First Time in 1,000 Years

Iceland was extensively forested when it was first settled. When the Vikings first arrived in the 9th century, the Nordic island was covered in 25 to 40 percent forest, compared to 1% in the present day. In the late 12th century, Ari the Wise (Ari Thorgilsson, 1067–1148 AD), Iceland’s most prominent medieval chronicler, described it […]

Climate Reanalyzer: Visual Climate and Weather Datasets

Today I stumbled upon on a beautiful web site: the Climate Reanalyzer. In fact, Chris Hadfield, the retired Canadian astronaut and also who was the first Canadian to walk in space, tweeted about the web site, saying “The current bulge of cold”. Then I visited the web site and found it really informative.

2018 Arctic Wintertime Sea Ice Extent is the Second Lowest On Record

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 […]

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 […]

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 […]
