According to IPCC Sixth Assessment Report, in the last 170 years, humans have caused the global temperature to increase to the highest level in the last 2,000 years. The current multi-century period is the warmest in the past 100,000 years. [3] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890.
Climate spirals use changing distance from a center point to represent change of a dependent variable (archetypically, global average temperature). [1] The independent variable, time, is broken down into months (represented by constantly changing rotational angle about the center point) and years (line colour that evolves as years pass). [1] [12]
In the years 2000–2021 the southwestern North American megadrought persisted. Climate change increased temperature, reduced the amount of precipitation, decreased snowpack and increased the ability of air to soak humidity, helping to create arid conditions. As of 2021 the drought was the most severe in the last 500 years. [65]
As a result of the increase in CO 2 dissolved in seawater, the oceans are acidifying. This results in a dissolution of the carbonates; global sedimentation becomes essentially clayey. This process takes place in less than 10,000 years while it will take about 100,000 years for the carbonate sedimentation to return to its pre-PETM level mainly by CO
The transient climate response (TCR) is defined as "the change in the global mean surface temperature, averaged over a 20-year period, centered at the time of atmospheric carbon dioxide doubling, in a climate model simulation" in which the atmospheric CO 2 concentration increases at 1% per year. [27]
The initial concept of visualizing historical temperature data has been extended to involve animation, [10] to visualize sea level rise [11] and predictive climate data, [12] and to visually juxtapose temperature trends with other data such as atmospheric CO 2 concentration, [13] global glacier retreat, [14] precipitation, [4] progression of ...
In recent decades, new high temperature records have substantially outpaced new low temperature records on a growing portion of Earth's surface. [1] Comparison shows seasonal variability for record increases. The list of weather records includes the most extreme occurrences of weather phenomena for various categories. Many weather records are ...
Logo of the ETTU Cup. The ETTU Cup is the second most important continental tournament for clubs in European table tennis, after the European Champions League.The European Table Tennis Union (ETTU) has organized this cup since the 1964-65 season for men teams, and also for women teams a year later.
