The report also stated that the increase in industrialization, urbanization and motorization will inevitably worsen this problem. [5] Pakistan holds the dubious distinction of being the world's third-most polluted country when it comes to air quality, compounding its environmental challenges.
Factors affecting Earth's climate can be broken down into forcings, feedbacks and internal variations. [14]: 7 Four main lines of evidence support the dominant role of human activities in recent climate change: [17]
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).
One historical long-term correlation between solar activity and climate change is the 1645–1715 Maunder minimum, a period of little or no sunspot activity which partially overlapped the "Little Ice Age" during which cold weather prevailed in Europe. The Little Ice Age encompassed roughly the 16th to the 19th centuries.
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [2] [3] just below the stratosphere.
Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
The climate of Rajasthan in northwestern India is generally arid or semi-arid and features fairly hot temperatures over the year with extreme temperatures in both summer and winter.
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting.The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century.
