Onset of modern sea level rise began in 1863: Study
Sea-level rise is an important indicator of broader climate changes. Identifying the time of sea-level rise helped researchers to pinpoint the onset of a significant period of climate change. The team used a global database of sea-level records spanning the last 2,000 years. They found that globally Industrial Revolution paved the way for the onset of modern rates of sea-level rise occurred in 1863.

New planet detected around star closest to the Sun
Proxima Centauri is the closest star to the Sun, lying just over four light years away. The newly discovered planet, named Proxima d, orbits Proxima Centauri at a distance of about four million kilometres, less than a tenth of Mercury's distance from the Sun. This candidate planet is the third detected in the system and the lightest yet discovered orbiting this star.
