The Governments of Nigeria and the Republic of Equatorial Guinea have opened discussions regarding new partnership opportunities such as the establishment of a joint logistics base, deployment of indigenous capacities across countries, and lowering the costs of major oil and gas operations. These possibilities were discussed on Wednesday when the Minister of Planning and Economic Diversification of the Republic of Equatorial Guinea, Mr. Gabriel Mbega Obiang Lima led a delegation to engage the Executive Secretary,…

The Hunga Tonga–Hunga Ha‘apai volcano in the area of the Tonga Islands in the South Pacific Ocean blew its top in a massive eruption in January 2022. In addition to an enormous plume of gas and debris, the eruption triggered pressure waves that rippled through the entire planet’s atmosphere, set off a sonic boom heard as far away as Alaska and unleashed a tsunami that swept over nearby islands. The dramatic event was particularly intriguing to scientists focused on elusive atmospheric phenomena; a host of satellites…

A temperature map of the Pacific Ocean for December 1993 showing a cold (blue) tongue of surface water stretching westward along the equator from the coast of South America. The temperature and extent of the cold tongue changes with the seasons, but new climate simulations show that the annual change in Earth’s distance from the sun also affects the cold tongue seasonal cycle. This influences El Niño conditions that impact weather in North America and globally. Credit: John Chiang, UC BerkeleyAn unrecognized effect boosts…

Latitudinal distribution of α for the LSAT of CRUTEM5 and 60 CMIP6 models. The change in the latitudinal range of the grids in the figure is consistent with that in the CRUTEM5 dataset, and the α value for each grid is the average α at this latitude.
