The average annual temperature in Tbilisi is 13.8 °C (56.8 °F). January is the coldest month with an average temperature of 2.7 °C (36.9 °F). July is the hottest month with an average temperature of 25.4 °C (77.7 °F). Daytime high temperatures reach or exceed 32 °C (90 °F) on an average of 22 days during a typical year.
The water cycle is essential to life on Earth and plays a large role in the global climate system and ocean circulation. The warming of our planet is expected to be accompanied by changes in the water cycle for various reasons. [3] For example, a warmer atmosphere can contain more water vapor which has effects on evaporation and rainfall.
Milankovitch emphasized the changes experienced at 65° north due to the great amount of land at that latitude. Land masses change temperature more quickly than oceans, because of the mixing of surface and deep water and the fact that soil has a lower volumetric heat capacity than water. [5]
The chlorine added to water in swimming pools and the salt in seawater allow the water to remain liquid at sub-zero temperatures. Swimming in such water is significantly more challenging and dangerous. The experienced winter swimmer Lewis Gordon Pugh swam near the North Pole in −1.7 °C (28.9 °F) water and suffered a frostbite injury in his ...
The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
Higher temperatures also directly degrade water quality. This is because warm water contains less oxygen. [185] Changes in the water cycle threaten existing and future water infrastructure. It will be harder to plan investments for water infrastructure. This is because there are significant uncertainties about future variability of the water ...
The onset and termination of the African Humid Period both occurred when the insolation cycle reached a value of roughly 4.2% higher than today. However, shifts in the insolation cycle are too gradual to cause abrupt climate transitions like those seen at the onset and termination of the African Humid Period all on their own.
The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.
