What is the effect of melting permafrost?
Releases methane, a potent greenhouse gas, further accelerating climate change.
What is the effect of rising temperatures on polar bears?
Melting ice destroys their habitat, making it difficult to hunt and survive.
What is the effect of melting ice on coastal areas?
Increases ocean volume, leading to rising sea levels and flooding in coastal regions.
What is the effect of increased CO2?
Increased CO2 traps more heat in the atmosphere, leading to global warming and climate change.
What is the effect of disrupted heat distribution?
Climate change can disrupt natural circulation patterns, leading to unpredictable weather.
What are the effects of melting ice and snow?
Habitat loss for polar animals, thawing permafrost releases methane, rising sea levels cause coastal flooding, and disruption of marine ecosystems.
What is the effect of rising sea levels?
Flooding in coastal areas, loss of coastal habitats, increased erosion, saltwater intrusion into freshwater sources, and displacement of human populations.
What is the effect of thawing permafrost?
Release of methane (a potent greenhouse gas), further accelerating climate change, destabilization of infrastructure built on permafrost, and changes to local ecosystems.
Define ice cores.
Cylinders of ice drilled from glaciers or ice sheets, containing trapped air bubbles that reveal past atmospheric composition and climate data.
Define positive feedback loop.
A process where an initial change triggers a series of events that amplify the original change, leading to an accelerating effect.
Define albedo.
The measure of how much light that hits a surface is reflected without being absorbed.
