  2. Climate change - Wikipedia

    en.wikipedia.org/wiki/Climate_change

    While methane only lasts in the atmosphere for an average of 12 years, [120] CO 2 lasts much longer. The Earth's surface absorbs CO 2 as part of the carbon cycle. While plants on land and in the ocean absorb most excess emissions of CO 2 every year, that CO 2 is returned to the atmosphere when biological matter is digested, burns, or decays. [121]

  3. Cub Scouts (Scouting America) - Wikipedia

    en.wikipedia.org/wiki/Cub_Scouts_(Scouting_America)

    Cub Scouts is a Scouting America program available to coeducational children from kindergarten through fifth grade (or 5 to 10 years of age) and their families. Its membership is the largest of the five main Scouting America divisions (Cub Scouting, Scouts BSA, Venturing, Exploring and Sea Scouting).

  4. Weather - Wikipedia

    en.wikipedia.org/wiki/Weather

    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.

  5. Climate system - Wikipedia

    en.wikipedia.org/wiki/Climate_system

    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).

  6. Illustrative model of greenhouse effect on climate change

    en.wikipedia.org/wiki/Illustrative_model_of...

    Earth constantly absorbs energy from sunlight and emits thermal radiation as infrared light. In the long run, Earth radiates the same amount of energy per second as it absorbs, because the amount of thermal radiation emitted depends upon temperature: If Earth absorbs more energy per second than it radiates, Earth heats up and the thermal radiation will increase, until balance is restored; if ...

  7. Here's why meteorologists launch weather balloons every day

    www.aol.com/weather/heres-why-meteorologists...

    Synchronized weather balloon launches have helped meteorologists create forecasts over the past 150 years, and now the old tradition is going high tech. Twice a day - every day of the year ...

  8. Greenhouse effect - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_effect

    Greenhouse gases make the atmosphere near Earth's surface mostly opaque to longwave radiation. The atmosphere only becomes transparent to longwave radiation at higher altitudes, where the air is less dense, there is less water vapor, and reduced pressure broadening of absorption lines limits the wavelengths that gas molecules can absorb. [56] [46]

  9. Weather forecasting - Wikipedia

    en.wikipedia.org/wiki/Weather_forecasting

    On an everyday basis, many people use weather forecasts to determine what to wear on a given day. Since outdoor activities are severely curtailed by heavy rain, snow and wind chill, forecasts can be used to plan activities around these events, and to plan ahead and survive them. Weather forecasting is a part of the economy.
