The value distribution is similar to floating point, but the value-to-representation curve (i.e., the graph of the logarithm function) is smooth (except at 0). Conversely to floating-point arithmetic, in a logarithmic number system multiplication, division and exponentiation are simple to implement, but addition and subtraction are complex.
2 March: a study published in Science said that boreal fires, typically accounting for 10% of global fire CO 2 emissions, contributed 23% in 2021, by far the highest fraction since 2000. [ 34 ] 2021 was an abnormal year because North American and Eurasian boreal forests synchronously experienced their greatest water deficit.

The triple point is at a temperature of 273.16 K (0.01 °C; 32.02 °F) and a pressure of 611.657 pascals (0.00604 atm; 0.0887 psi); [71] it is the lowest pressure at which liquid water can exist. Until 2019 , the triple point was used to define the Kelvin temperature scale .
According to this revised World Bank methodology, India had 179.6 million people below the new poverty line, China had 137.6 million, and the world had 872.3 million people below the new poverty line on an equivalent basis as of 2013. India, in other words, while having 17.5% of total world's population, had 20.6% share of world's poor.
Dioxygen gas currently constitutes 20.95% molar fraction of the Earth's atmosphere, though this has changed considerably over long periods of time in Earth's history. Oxygen makes up almost half of the Earth's crust in the form of various oxides such as water , carbon dioxide , iron oxides and silicates .
Ancient Germanic paganism was a polytheistic religion practised in prehistoric Germany and Scandinavia, as well as Roman territories of Germania by the first century AD. It had a pantheon of deities that included Donar/Thunar, Wuotan/Wodan, Frouwa/Frua, Balder/Phol/Baldag, and others shared with northern Germanic paganism. [13]
