The Weather of April 2022 – An extremely dry and sunny April With dry northeast monsoon affecting Hong Kong and less moisture supply to the south China coast for most of the time in the month, April 2022 was much drier than usual in Hong Kong. The total rainfall in the month was 3.5 millimetres, only about 2 percent of the normal figure of 153.0 millimetres and the lowest on record for April. The month was also much sunnier than usual, the total duration of bright sunshine in the month was 191.1 hours, about 69 percent above the normal.
Massive amount of water found below Antarctica’s ice sheet for 1st time Hidden deep below the ice sheet that covers Antarctica, scientists have discovered a massive amount of water. The groundwater system, found in deep sediments in West Antarctica likely to be the consistency of a wet sponge, reveals an unexplored part of the region and may have implications for how the frozen continent reacts to the climate crisis, according to new
Climate change: Key UN finding widely misinterpreted In the latest IPCC climate report, researchers wrote that greenhouse gases are projected to peak “at the latest before 2025”. This implies that carbon could increase for another three years and the world could still avoid dangerous warming. But scientists say that’s incorrect and that emissions need to fall immediately.
Extremely high pre-monsoon temperatures over Pakistan and northern India April 2022 was globally around the sixth warmest April since records began. April temperatures over much of Europe were close to average values for 1991-2020. Temperatures were unusually high from north-eastern Africa across the Middle East to central and southern Asia. Pre-monsoon temperatures were extremely high over Pakistan and northern India.
Climate change and farming driving insect decline Insect numbers have plunged by half in some parts of the world due to climate change and intensive agriculture, a study has found. The combined pressures of global heating and farming are driving a “substantial decline” of insects across the globe, according to UK researchers. They say we must acknowledge the threats we pose to insects, before some species are lost forever.
NASA’s EMIT will map tiny dust particles to study big climate impacts NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission, set for launch in June, aims to deepen researchers’ understanding of these fine particles of soil, silt, and clay from Earth’s deserts and, ultimately, how they affect climate. Researchers at NASA and elsewhere have long focused on dust’s flight. Its atmospheric impacts are included in climate models, but it remains unclear whether dust has a net warming or cooling effect on the planet, and how this is changing over time(video).
Life below water: Interactive status of world coral reefs The Status of Coral Reefs of the World: 2020 is a report by the Global Coral Reef Monitoring Network, a network of the International Coral Reef Initiative. Its findings show that between 2009 and 2018 there was a progressive loss of about 14 per cent of the coral from the world’s coral reefs primarily caused by recurring, large-scale bleaching events. In all, about 11,700 square kilometres of hard coral, which is more than all the coral currently living on Australia’s coral reefs, were lost.
