The traditional Chinese calendar divides a year into 24 solar terms. [1] Chǔshǔ, Shosho, Cheoseo, or Xử thử (traditional Chinese: 處暑; simplified Chinese: 处暑; pinyin: chǔshǔ; Japanese: 処暑; rōmaji: shosho; Korean: 처서; romaja: cheoseo; Vietnamese: xử thử; lit. 'limit of heat') is the 14th solar term that signifies the end of the hot summer season. [2]
A heat pump is a device that provides heat energy from a source of heat to a destination called a "heat sink". Heat pumps are designed to move thermal energy opposite to the direction of spontaneous heat flow by absorbing heat from a cold space and releasing it to a warmer one.
Solar radiation modification (SRM) (or solar radiation management or sunlight reflection methods [1] or solar geoengineering), is a group of large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.
Earth last year shattered global annual heat records, flirted with the world’s agreed-upon warming threshold and showed more signs of a feverish planet, the European climate agency said Tuesday.
The Intergovernmental Panel on Climate Change (IPCC) had been formed by the United Nations in 1988, [29] [30] and it presents reports summarizing the strength and extent of consensus on climate change and its numerous aspects to the member states of the United Nations, with the major reports released at 5-to-7-year intervals starting from 1990 ...
For example, with an axial tilt is 23°, and at a latitude of 45°, then the summer's peak sun angle is 68° (giving sin(68°) = 93% insolation at the surface), while winter's least sun angle is 22° (giving sin(22°) = 37% insolation at the surface). Thus, the greater the axial tilt, the stronger the seasons' variations at a given latitude.
