Increased number of extreme forest fires due to climate change has become a global problem
Energetically extreme fires have a huge impact on the Earth system, releasing huge plumes of smoke into the atmosphere comparable to volcanic eruptions. They release vast stores of carbon and cause severe damage to ecosystems and societies, sometimes destroying entire cities or suburbs. A new study published in the journal Nature Ecology and Evolution has tracked the rapid increase in energetically extreme wildfires across the planet over the past two decades.
Jet fuel and fires are new global air pollutants
Wildfires in Canada have emitted more CO2 than almost all of the world’s countries combined in a year. They have released 647 million tons of carbon atoms into the atmosphere, equivalent to 2.4 billion tons of carbon dioxide. Ultrafine particles from jet fuel pose a health risk.
Forest industry entrepreneurs believe that deforestation is good for the environment
Their opponents argue that trees need time to grow again and soil needs time to store carbon again. Forestry “reduces the total amount of carbon in terrestrial ecosystems”, leading to a decline in wild flora and fauna.
Canadian scientists have achieved that 80 percent of organs for transplantation have become universal
The new technology involves replacing the second blood group of a donor organ with the first. The article says that this is already enough for 80% of organs selected for transplantation to become universal.
