The Weather of July 2022 – A July with record-breaking high temperatures With a stronger than usual subtropical ridge persisting over southern China and bringing prolonged high temperature weather to the region in the month, July 2022 was the hottest month in Hong Kong since records began in 1884, breaking the previous record set in July 2020. With a total of 25 hot nights, July 2022 was the month with the highest number of hot nights on record and the 21 consecutive hot nights that started from 9 July also set a new record.
“This heatwave is the new normal,” says WMO Secretary-General “In the future, this kind of heatwaves are going to be normal. We will see stronger extremes. We have pumped so much carbon dioxide in the atmosphere that the negative trend will continue for decades. We haven’t been able to reduce our emissions globally,” said Prof. Taalas. “I hope that this will be a wake-up call for governments and that it will have an impact on voting behaviors in democratic countries”, he said.
Climate change: More studies needed on possibility of human extinction Catastrophic climate change outcomes, including human extinction, are not being taken seriously enough by scientists, a new study says. According to this new analysis, the closest attempts to directly understand or address how climate change could lead to global catastrophe have come from popular science books such as The Uninhabitable Earth and not from mainstream science research.
Climate impacts have worsened vast range of human diseases More than half of the human diseases caused by pathogens have been worsened at some point by the sort of impacts associated with the climate crisis, a new and exhaustive study of the link between disease and climatic hazards has found. Diseases such as Zika, malaria, dengue, chikungunya and even Covid-19 have been aggravated by climate impacts such as heatwaves, wildfires, extreme rainfall and floods.
Chinese companies seek global carbon market for green hydrogen A project that supplied green hydrogen for buses at the Winter Olympics could be the first of its kind to sell carbon credits through the UN’s Clean Development Mechanism (CDM). Three Chinese organisations are leading the charge to create an international carbon market for green hydrogen. They have proposed a methodology, pending approval from CDM, for calculating emission reductions from green hydrogen projects to sell as carbon credits. The buyers of those reductions – mainly countries and companies – could use them towards their net zero goals.
