The Weather of June 2021 – A June with rejuvenating rain

June 2021 was marked by the long awaited rainy weather brought by tropical cyclone Koguma, troughs of low pressure and the active southwesterly airstream. The rain was particularly heavy and persistent on the morning of 28 June and the incessant downpour necessitated the issuance of the first Black Rainstorm Warning this year.

IPCC Working Group I will release its contribution to AR6 on 9 August 2021

The Intergovernmental Panel on Climate Change (IPCC) will release its next report, the Working Group I contribution to the Sixth Assessment Report (AR6), on 9 August 2021. The report will provide the latest assessment of scientific knowledge about the warming of the planet and projections for future warming, and assess its impacts on the climate system.

Fengyun 3E satellite to improve morning weather forecasts

Fengyun 3E, lifted into orbit by a Long March 4C carrier rocket launched from the Jiuquan Satellite Launch Center on 5 July, is tasked with obtaining data and images at 5:30 am and 5:30 pm.

Major ocean-observing satellite starts providing science data

After six months of check-out and calibration in orbit, the Sentinel-6 Michael Freilich satellite will make its first two data streams available to the public on June 22. It launched from Vandenberg Air Force Base in California on Nov. 21, 2020, and is a U.S.-European collaboration to measure sea surface height and other key ocean features, such as ocean surface wind speed and wave height.

Death Valley breaks into top 5 again with 130-degree reading

But as hot at 130 may be, it is not the hottest temperature ever for Death Valley — which is 134 degrees, set in 1913. That is also considered the official world record, but it is a bit of a controversial one. The WMO determined the Libya measurement (136.4 degrees Fahrenheit in 1923 in Al Azizia, Libya) was faulty in 2012 and officially de-certified it as the official all-time highest global temperature, giving that designation instead to the Death Valley temperature on July 10, 1913.

The amount of heat the Earth traps has doubled in just 15 years, study shows

The planet is trapping roughly double the amount of heat in the atmosphere than it did nearly 15 years ago, according to an alarming new analysis from NASA and the National Oceanic and Atmospheric Administration. The excess energy being taken up by the planet is going to mean further increases in temperatures and more melting of snow and sea ice, which will cause sea level rise — all things that society really cares about.

North America heatwave almost impossible without climate change

The record-breaking heatwave in parts of the US and Canada at the end of June would have been virtually impossible without the influence of human-caused climate change, according to a rapid attribution analysis by an international team of leading climate scientists. Climate change, caused by greenhouse gas emissions, made the heatwave at least 150 times more likely to happen.

Antarctica hit record-high temperatures in 2020

The World Meteorological Organization confirmed this week that temperatures in Antarctica reached a new record high in 2020. The continent reached 64.94 degrees Fahrenheit (18.3 Celsius) in February of last year, compared to the previous record of 63.5 degrees (17.5 Celsius) recorded in 2015. Both temperatures were recorded at the Argentine Esperanza Research Station.
