World Scientists' Warning 2022
Torstai 3.11.2022 klo 13.43 - Mikko Nikinmaa
The alliance of world scientists, with the lead of William Ripple in Oregon, have again done a report of what has been happening during the recent past. The report is published in BioScience and can be accessed freely at https://doi.org/10.1093/biosci/biac083. The year 2022 has been characterized by a multitude of climate-related disasters, which the report tabulates. I have taken the information from the table and give it below.
In addition, the film “The Scientist’s Warning” has now been released and is free to view online at https://scientistswarningfilm. Further, different climate-related resources can be accessed in the Alliance of World Scientists website https://scientistswarning.forestry.oregonstate.edu/
Climate disasters in 2022.
Many rivers in Europe have run low or dried up partly because of the worst drought in 500 years and intense heat waves. Climate change has likely played a significant role in this crisis by increasing the frequency and intensity of droughts and heat waves.
La Niña and climate change contributed to record-breaking rainfall on the east coast of Australia. This led to flooding that damaged thousands of properties and killed eight people.
Record-breaking flooding occurred along the northeastern coast of Australia, leading to standing water, which, in turn, promoted the spread of mosquitoes that carry the Japanese encephalitis virus. Such flooding is likely becoming more common because of climate change.
The number of people affected by drought in Kenya, Somalia, and Ethiopia who have limited access to safe water increased from 9.5 million to 16.2 million. This increasing drought severity may be at least partly due to climate change (Ghebrezgabher et al. 2016).
A severe drought in the Southern Plains of the United States put the winter wheat crop at risk. Although droughts are complex phenomena with many possible causes, increasing drought intensity has been linked to climate change (Mukherjee et al. 2018).
A deadly heat wave occurred in India and Pakistan, killing at least 90 people and contributing to widespread crop losses and wildfires. It was estimated that climate change made this event 30 times more likely to occur.
Climate change likely contributed to extreme rainfall in Eastern South Africa, which triggered flooding and landslides that killed at least 435 people and affected more than 40,000 people.
Widespread dust storms in the Middle East led to thousands of people being hospitalized; such dust storms may be increasing in frequency because of climate change.
Extremely heavy rainfall in northeastern Brazil resulted in landslides and flooding that killed at least 100 people. Climate change may be responsible for the increasing frequency of extreme rainfall.
A severe storm in Yellowstone (United States) caused the Gardner River and Lamar River to overflow, destroying parts of various roads in Yellowstone National Park. Such extreme flooding could be increasing in frequency because of climate change.
Several countries in Western Europe experienced a record-breaking heat wave. This heat wave contributed to major wildfires in Spain and Germany. Many other parts of the Northern Hemisphere also experienced extreme heat; for example, temperatures reached 104.4 degrees Fahrenheit in Isesaki, Japan—an all-time record for the country. Similarly, a heat dome in the United States contributed to record-breaking temperatures. Other affected countries include Finland, Iran, Norway, and Italy. In general, extreme heat is becoming more common because of climate change (Luber and McGeehin 2008).
Following extreme heat, China experienced record-breaking rainfall, which may be linked to climate change.
Bangladesh experienced the worst monsoon flooding in 100 years, killing at least 26 people. This flooding is likely at least partly due to climate change causing monsoons to become more variable.
Extreme rainfall led to flooding in some parts of New South Wales, Australia. Sydney is currently on track to experience the wettest year on record. It is likely that climate change contributed at least partly to this rainfall and flooding.
Deadly floods in Pakistan have killed more than 1,000 people and affected roughly 33 million people, including 16 million children, since mid-June. Impacts include surging rates of dengue fever, gastric infections, and malaria. These floods may be at least partly related to climate change causing monsoon rainfall to become more intense.
China experienced an extraordinary heat wave, which may be the most severe that has ever been recorded globally. Such events are likely becoming more common because of climate change. The extreme heat contributed to large-scale crop failures and wildfires, in addition to exacerbating a major drought that caused 66 rivers to dry up and led to a significant decline in hydroelectricity generation.
California and other parts of the Western United States faced extremely hot temperatures because of a heat dome, which caused seven firefighters to be hospitalized with heat-related injuries. The effects of the heat dome may have been worsened by climate change.
In the United States, Hurricane Ian caused damage across many parts of Florida and the Carolinas, killing more than 100 people and leaving at least 2.5 million without electrical power. Ian is one of the costliest and strongest hurricanes to ever hit the United States. Climate change is likely causing strong and rapidly intensifying storms such as Ian to become more common.
