Weather- Meant to be short-term, local, point in time atmospheric conditions such as temperature, precipitation, pressure and humidity.
Climate - Meant to be average weather patterns over a longer period of time (years, decades) across the globe.
Greenhouse Effect - Global Warming i.e. sustained rise in average temperatures across the planet due to heat (solar radiation) being trapped by anthropogenic emissions called greenhouse gases in the atmosphere
Greenhouse Gases - CO2 (about 80% of US GHG) comes mainly from fossil fuel combustion for energy,
Methane (CH4), which comes from landfills, coal mines, agriculture, and oil and natural gas operations,
Nitrous oxide (N2O), which comes from using nitrogen fertilizers and certain industrial and waste management processes and burning fossil fuels,
High global warming potential (GWP) gases, which are human-made industrial gases,
Sulfur hexafluoride (SF6),
Nitrogen trifluoride (NF3) - source U.S. Energy Information Administration
Climate Change Climate change is a gradual rise in global teperatures since the industrail revolution began circa 1850 due to GHG emissions and other second order effects, resulting in extreme weather events - floods, hurricanes, droughts and the long term effects such as melting ice and rising sea levels.`
