Forests and climate change | IUCN

2021-11-20 · Forests'' role in climate change is two-fold. They act as both a cause and a solution for greenhouse gas emissions. Around 25% of global emissions come from the land sector, the second largest source of greenhouse gas emissions after the energy sector. About half of these (5-10 GtCO 2 e annually) comes from deforestation and forest degradation.

What Effect Does Acid Rain Have on Rocks?

2020-3-31 · What Effect Does Acid Rain Have on Rocks? Acid rain slowly dissolves many types of stone. Calcium-based minerals such as marble and limestone are particularly vulnerable; this is due to calcium''s reaction with the sulfuric acid in acid rain. Acid rain''s ability to dissolve marble and limestone makes it hazardous to buildings and outdoor monuments.

Thermal mass

2021-10-14 · Thermal mass refers to the material inside a building that can help reduce the temperature fluctuations throughout the course of the day; thus reducing the heating and cooling demand of the building itself. Thermal mass materials achieve this effect by absorbing heat during periods of high solar insolation, and releasing heat when the surrounding air begins to cool.
