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.
Scientists have linked the development of life with a magnetic field and concluded about magnetic fields on other planets
The weakening of the Earth’s magnetic field has led to a dramatic acceleration in the evolution of multicellular life. Fossil evidence has been found in Brazil and South Africa that the strength of the Earth’s magnetic field was about 30 times weaker than today’s values at the end of the Ediacaran period, about 590 to 560 million years ago. One of the defining features of the Earth is its magnetic field. It forms a protective shield against high-energy particles ejected by the Sun, and thus may have provided a safer place for life to grow into the complex array of organisms we see today.
Scientists have found that life on our planet could not have appeared without the Earth’s magnetic field
The movement of the iron core generates electricity, which results in a magnetic orientation of the entire planet. Scientists can trace the magnetic history of our planet through cooled lava. Because the planet’s magnetism deflects solar radiation, it allows life to exist on Earth. In fact, throughout the history of our planet, the poles have even changed their position several times, and the magnetic field strength has increased and decreased. The rocks indicate that Earth had a strong magnetic field 3.7 billion years ago, but scientists are not sure where the field might have come from. Magnetized boulders have also been discovered on the Moon.
Global warming will allow species of flora and fauna to colonize previously uncharacteristic territories
In Russia, it was revealed that the fauna of Siberia is becoming more southern due to climate change. Global warming will allow tropical species from the Atlantic to colonize the Mediterranean Sea. Global warming is making some species of marine animals more susceptible to the spread of diseases such as avian influenza due to the animals congregating in breeding and feeding areas or changing migration patterns. Some researchers are concerned that current rates of warming could make oceans as warm and acidic as they were during the end of the Permian extinction, 250 million years ago, when up to 90 percent of marine species died out.
Microplastics have been found in the bodies of people, animals and in various parts of the world – from snow in the distant Arctic to the clouds of Mount Fuji
Researchers are already finding microplastics in all environments and organisms. There is still no clear opinion about the dangers of micro- (particles less than 5 mm) and nanoparticles (less than 100 nm) plastic to humans and to the terrestrial biota in general. Apparently, common plastics such as polyethylene and polypropylene are harmless in themselves. However, additives added by manufacturers to plastics to improve their performance properties and which are secret know-how to society and regulatory authorities can cause serious harm to the environment. And most importantly, plastic particles are adsorbents and carriers of chemical and bacterial pollution.
More than 100 world leaders have pledged to end deforestation by 2030
More than 100 world leaders have pledged to end deforestation by 2030 in the first major deal at the Glasgow climate summit. Countries that supported the decision include Brazil, Russia, Canada, Colombia, the US, the UK and Indonesia. It is noted that in total these countries account for about 85% of the world’s forests. The agreement includes the allocation of $20 billion, part of which will be used to restore already damaged forest areas and fight forest fires. The governments of 28 countries also pledge to stop deforestation for agricultural production, in particular for the production of palm oil, cocoa and soybeans.
The largest living organism on Earth is the mycelium of the honey fungus, its age is more than 2.5 thousand years
The honey mushroom is recognized as the largest living organism in the world. Or rather, not he himself, but his mycelium, which amazes even experienced mushroom pickers and biologists with its parameters. This giant creature grows in the Malheur Wildlife Refuge in eastern Oregon (USA). Its territory covers about 1,000 hectares; about 1,600 football fields could fit on it. The weight of the mycelium Humongous Fungus subspecies Armillaria ostoyae exceeds 600 tons, and its age is more than 2500 years.
