Both global climate simulations and worldwide ocean temperature reconstructions indicate that the cooling in the tropics during the last cold period, which began about 115,000 years ago, was much weaker than in the temperate zone and the polar regions...

New model more accurately predicts how massive glaciers melt Statistical models of the topography of glacier beds will lead to more accurate predictions of heat flow and subsequent ice melt for decades to come By Lisa Ercolano / Published Feb 23, 2021 New research by a team that included a Johns Hopkins engineer promises to enable more accurate ice-flow predictions, helping scientists better forecast how melting glaciers will contribute to rising sea levels, which have been linked to coastal and wetland flooding and destructive erosion around the worl...

Bond rating and has technology that puts faa to shame. they have digital pilot control or messaging across the country and north atlantic which we don't have yet and won't have for another eight years on a nationwide basis. they have -- they are putting in global satellite surveillance through an entity they created that 70% of the world's earth surface doesn't have a radar. planes are just up there and they have to have huge buffer zones around them because the controllers don't know exactly where they are but with satellite-base surveillance started in 2018 will know exactly where they are o...
