Climate change is a long-term shift in temperatures and weather patterns. These shifts can be natural, but since the 1800s, human activities such as burning of fossil fuels (like coal, oil, and gas) produce heat-trapping carbon emission gases.
Severe heat and drought due to climate change can fuel wildfires. Hotter temperatures evaporate more moisture from soil and vegetation, drying out trees, shrubs and grasses and turning leaf litter and fallen branches into kindling.
Climate change impacts rising sea levels; shrinks mountain glaciers; accelerates ice melt in Greenland, Antarctica and the Arctic; and shifts flower/plant blooming times.
