FUNAFUTI, TUVALU - NOVEMBER 28: An aerial view of downtown and the airport runway, between the Pacific Ocean (L) and lagoon (R), on November 28, 2019 in Funafuti, Tuvalu. The??low-lying??South Pacific island nation??of about 11,000 people has been classified as ???extremely vulnerable??? to climate change by the??United Nations Development Programme.??The world???s fourth-smallest country is struggling to cope with climate change related impacts including five millimeter per year sea level rise (above the global average), tidal and wave driven flooding, storm surges, rising temperatures, saltwater intrusion and coastal erosion on its nine coral atolls and islands, the highest of which rises about 15 feet above sea level. In addition, the severity of cyclones and droughts in the Pacific Island region are forecast to increase due to global warming. Some scientists have predicted that Tuvalu could become inundated and uninhabitable in 50 to 100 years or less if sea level rise continues.??The country is working toward a goal of 100 percent renewable power generation by 2025 in an effort to curb pollution and set an example for larger nations. Tuvalu is also exploring a plan to build an artificial island. (Photo by Mario Tama/Getty Images)

The Australia-Tuvalu climate migration treaty is a drop in the ocean

Australia has offered a lifeline to the people of Tuvalu, whose island is threatened by rising sea levels. But the deal comes with strings attached – and there will be millions more climate migrants in need of refuge by 2050

Women's pelvises are shrinking – how is that changing childbirth?

Over the past 150 years, the rise in Caesarean sections and changes in diet could have led to smaller pelvises among women – which may make vaginal birth more difficult but could also reduce common conditions associated with childbirth

This is a supercell photographed near Arnett, Oklahoma on June 17th. At the moment of the picture, a tornado is ongoing in the center of the image buried in rain, and hail bigger than 55mm (2.17???) is falling and being collected by the hail hunting vehicle. The lightning was prolific because the storm was well over 65,000 feet tall during its peak strength. The lightning was so constant that in 1/8th of a second (the exposure time of this picture), I was able to capture 3 strikes. Most of the lightning was positive, which is stronger than the typical lightning strike which are negative. This can be an indicator of an abundance of hail within the storm, as hail can increase the amount of built up electrical charge within the updraft. Positive strikes typically originate from the top of the storm (anvil) and are characterized by one singular channel without much branching (leftmost strike). Typically striking within the inflow of the storm, they also only strike once instead of strobing with multiple strokes/pulses like negatively charged lightning does. Hope this is enough information about the storm! I can always share more if needed.
