Mikhail Budyko
Mikhail Ivanovich Budykorussian: Михаил Иванович Будыко (20 January 1920 – 10 December 2001) was a Soviet and Russian climatologist and one of the founders of physical climatology. He pioneered studies on global climate and calculated temperature of Earth considering simple physical model of equilibrium in which the incoming solar radiation absorbed by the Earth's system is balanced by the energy re-radiated to space as thermal energy. Budyko's groundbreaking book, ''Heat Balance of the Earth's Surface'', published in 1956, transformed climatology from a qualitative into a quantitative physical science. These new physical methods based on heat balance were quickly adopted by climatologists around the world. In 1963, Budyko directed the compilation of an atlas illustrating the components of the Earth's heat balance. Life Ethnically Belarusian, Budyko earned his M.Sc. in 1942 from the Division of Physics of the Leningrad Polytechnic Institute. As a researc ...

Gomel
Gomel (russian: Гомель, ) or Homiel ( be, Гомель, ) is the administrative centre of Gomel Region and the second-largest city in Belarus with 526,872 inhabitants (2015 census). Etymology There are at least six narratives of the origin of the city's name. The most plausible is that the name is derived from the name of the stream Homeyuk, which flowed into the river Sozh near the foot of the hill where the first settlement was founded. Names of other Belarusian cities are formed along these lines: for example, the name Minsk is derived from the river Menka, Polatsk from the river Palata, and Vitsebsk from the river Vitsba. The first appearance of the name, as "Gomy", dates from 1142. Up to the 16th century, the city was mentioned as Hom', Homye, Homiy, Homey, or Homyi. These forms are tentatively explained as derivatives of an unattested ''*gomŭ'' of uncertain meaning. The modern name for the city has been in use only since the 16th or 17th centuries.

Arctic Sea Ice Decline
Arctic sea ice decline has occurred in recent decades due to the effects of climate change on oceans, with declines in sea ice area, extent, and volume. Sea ice in the Arctic Ocean has been melting more in summer than it refreezes in the winter. Global warming, caused by greenhouse gas forcing is responsible for the decline in Arctic sea ice. The decline of sea ice in the Arctic has been accelerating during the early twenty‐first century, with a decline rate of minus 4.7% per decade (it has declined over 50% since the first satellite records). It is also thought that summertime sea ice will cease to exist sometime during the 21st century. This sea ice loss is one of the main drivers of surface-based Arctic amplification. Sea ice area means the total area covered by ice, whereas sea ice extent is the area of ocean with at least 15% sea ice, while the volume is the total amount of ice in the Arctic. The region is at its warmest in at least 4,000 years and the Arctic-wide melt se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Engineering
Climate engineering (also called geoengineering) is a term used for both carbon dioxide removal (CDR) and solar radiation management (SRM), also called solar geoengineering, when applied at a planetary scale.IPCC (2022Chapter 1: Introduction and FramingiClimate Change 2022: Mitigation of Climate Change.

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Sulfate Aerosol
The term sulfate aerosols is used for a suspension of fine solid particles of a sulfate or tiny droplets of a solution of a sulfate or of sulfuric acid (hydrogen sulfate). They are produced by chemical reactions in the atmosphere from gaseous precursors (with the exception of sea salt sulfate and gypsum dust particles). The two main sulfuric acid precursors are sulfur dioxide (SO2) from anthropogenic sources and volcanoes, and dimethyl sulfide (DMS) from biogenic sources, especially marine plankton. These aerosols can cause a cooling effect on earth. However the UNFCCC has noted that sulfate aerosols remain in the atmosphere for only a short amount of time in comparison to well-mixed greenhouse gases, and therefore their cooling is localized and temporary. Other side effects of sulfate aerosols in the environment include poor air quality.http://unfccc.int/essential_background/background_publications_htmlpdf/climate_change_information_kit/items/72.php UNFCC, Climate Change Informat ...

Solar Geoengineering
Solar geoengineering, or solar radiation modification (SRM), is a type of climate engineering in which sunlight (solar radiation) would be reflected back to outer space to limit or reverse human-caused climate change. It is not a substitute for reducing greenhouse gas emissions, but would act as a temporary measure to limit warming while emissions of greenhouse gases are reduced and carbon dioxide is removed. The most studied methods of SRM are stratospheric aerosol injection and marine cloud brightening. Solar geoengineering appears able to prevent some or much of climate change temperature increases. Climate models consistently indicate that it is capable of returning global, regional, and local temperatures and precipitation closer to pre-industrial levels. Solar geoengineering's principal advantages are the speed with which it could be deployed and become active and the reversibility of its direct climatic effects, although the latter varies depending on method, with some c ...

IPCC First Assessment Report
The First Assessment Report (FAR) of the Intergovernmental Panel on Climate Change (IPCC) was completed in 1990. It served as the basis of the United Nations Framework Convention on Climate Change (UNFCCC). This report had effects not only on the establishment of the United Nations Framework Convention on Climate Change (UNFCCC), but also on the first conference of the parties (COP), held in Berlin in 1995. The executive summary of the WG I Summary for Policymakers report said they are certain that emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases, resulting on average in an additional warming of the Earth's surface. They calculated with confidence that CO2 had been responsible for over half the enhanced greenhouse effect. They predicted that under a "business as usual" (BAU) scenario, global mean temperature would increase by about 0.3 °C per decade during the 1stcentury. They judged that globa ...

Yuri Izrael
Yuri Antonievich Izrael (russian: Юрий Антониевич Израэль; 15 May 1930, Tashkent – 23 January 2014, Moscow) was a Soviet and Russian meteorologist. He served as the vice-chairman of the Intergovernmental Panel on Climate Change (IPCC) until September 2008, when the new bureau was elected. He was the "most influential scientific adviser" for Vladimir Putin, the president of Russia, according to CNN. Izrael was former chairman of the Committee for Hydrometeorology. He also served as director of the Institute of Global Climate and Ecology, which is a part of the Russian Academy of Sciences. He was a first vice-president of the World Meteorological Organization and helped develop the World Weather Watch. In 1992, Izrael won the International Meteorological Organization Prize and the UNEP Sasakawa Environment Prize for, among other accomplishments, contributing to the "success of Working Group I I" of the IPCC.

Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately and is known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is t ...

Polar Ice Cap
A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice. There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land, but only that it must be a body of solid phase matter in the polar region. This causes the term "polar ice cap" to be something of a misnomer, as the term ice cap itself is applied more narrowly to bodies that are over land, and cover less than 50,000 km2: larger bodies are referred to as ice sheets. The composition of the ice will vary. For example, Earth's polar caps are mainly water ice, whereas Mars's polar ice caps are a mixture of solid carbon dioxide and water ice. Polar ice caps form because high-latitude regions receive less energy in the form of solar radiation from the Sun than equatorial regions, resulting in lower surface temperatures. Earth's polar caps have changed d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Sensitivity
Climate sensitivity is a measure of how much Earth's surface will cool or warm after a specified factor causes a change in its climate system, such as how much it will warm for a doubling in the atmospheric carbon dioxide () concentration. In technical terms, climate sensitivity is the average change in global mean surface temperature in response to a radiative forcing, which drives a difference between Earth's incoming and outgoing energy. Climate sensitivity is a key measure in climate science, and a focus area for climate scientists, who want to understand the ultimate consequences of anthropogenic global warming. The Earth's surface warms as a direct consequence of increased atmospheric , as well as increased concentrations of other greenhouse gases such as nitrous oxide and methane. The increasing temperatures have secondary effects on the climate system, such as an increase in atmospheric water vapour, which is itself also a greenhouse gas. Scientists do not know exactly h ...
