    en.wikipedia.org/wiki/Environmental_issues_in...

    Landscape of United Arab Emirates Environmental issues in the United Arab Emirates (UAE) are caused by the exploitation of natural resources, rapid population growth, and high energy demand. The continuing temperature rise caused by global warming contributes to UAE's water scarcity, drought, rising sea level, and aridity. The UAE has a hot desert climate, which is very vulnerable to the ...

  5. Effects of climate change on the water cycle - Wikipedia

    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.

    [3] Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries.

  8. Nonpoint source pollution - Wikipedia

    en.wikipedia.org/wiki/Nonpoint_source_pollution

    Nonpoint source (NPS) pollution refers to diffuse contamination (or pollution) of water or air that does not originate from a single discrete source. This type of pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. It is in contrast to point source pollution which results from a single source.

  9. Climate system - Wikipedia

    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).
