Oman currently relies heavily on fossil fuels, generating up to 85% of its GDP from oil and gas, but its fossil fuel reserves are dwindling and becoming increasingly costly to extract. In December 2020, the country published its Oman Vision 2040 strategy, a plan to diversify the economy away from fossil fuels and increase investment in renewables.
Green hydrogen could play an important role, said Eastman, thanks to the Omanâs combination of plentiful daytime sun and strong winds at night. âOman is one of the places in the world that Iâve called the âfuture renewable superpowersâ,â said Michael Liebreich, the founder of BloombergNEF, âbecause what you really want [to produce green hydrogen] is very cheap solar and very cheap wind.â

A stability analysis of the ice sheet covering a large area of Greenland suggests that the ice melting may be approaching a point of no return.
Copernicus Sentinel data, processed by ESA Satellite image of the Jakobshavn Glacier the fastest retreating glacier in Greenland. The analysis of melt rates in the last 150 years indicates the glacier might be approaching a tipping point.

Of the over 400 climate scenarios assessed in the 1.5°C report by the Intergovernmental Panel on Climate Change (IPCC), only around 50 scenarios avoid significantly overshooting 1.5°C. Of those only around 20 make realistic assumptions on mitigation options, for instance the rate and scale of carbon removal from the atmosphere or extent of tree planting, a new study shows. All 20 scenarios need to pull at least one mitigation lever at challenging rather than reasonable levels.
NASA is developing a new program to use more satellites to help the U.S. government better understand the effects of climate change and extreme weather events.
