The highest R-values are assigned to the materials that provide the ___________
Greatest amount of insulation and the greatest resistance to heat flow
R value
Insulation of wall, roofs and floors. has to do with capacity of a material to resist heat flow. Lower the R value, lower insulation.
Kyoto Protocol
International treaty that stated CO2 is culprit of climate change caused by humans. Nations must come together.
Why is night time light pollution a problem?
It can affect our safety as it takes time for human eyes to adjust from dark to light surroundings It limits our view of the night sky It can adversely affect sleep and migration patterns of nocturnal animals
