<p>Some potential impacts of climate change on Canada mentioned in the text are increased snowfall, erosion due to loss of sea ice causing more wave action at shore, the need for costly all-weather roads to support mines and communities due to the disappearance of ice roads, threats to infrastructure and remote microwave towers from wildfires below the tree line, and the melting of permafrost which threatens structures such as roads, runways, pipelines, and fuel storage.</p> Signup and view all the answers

<p>Some evidence for a warming climate mentioned in the text are CO2 increase, temperature increase, sea-surface temperature increase, sea-level rise, loss of sea ice and ice sheets, retreat of glaciers, and more weather-related disasters.</p> Signup and view all the answers

<p>The loss of sea ice and ice sheets leads to sea-level rise, which can have significant impacts on global climate and temperature. Additionally, it can contribute to the loss of albedo, further exacerbating climate change.</p> Signup and view all the answers

<p>Climate forcing refers to the drivers of climate change that can cause the climate to deviate from its normal state. Examples of climate forcing drivers mentioned in the text include greenhouse gases, aerosols, changes in solar radiation, and burning of fossil fuels.</p> Signup and view all the answers

<p>Climate tipping points refer to abrupt and irreversible shifts in the climate system. Examples mentioned in the text include ocean circulation changes leading to cooling in Europe and warming in North America, ice loss causing runaway heating, and rapid release of methane from thawing permafrost.</p> Signup and view all the answers

<p>Forests act as a carbon sink by removing CO2 from the atmosphere through photosynthesis, thus helping to reduce the concentration of greenhouse gases. This process contributes to a negative climate feedback, stabilizing the climate by reducing the effects of forcing.</p> Signup and view all the answers

<p>Ice albedo refers to the reflective properties of ice, and its loss leads to increased absorption of heat by the Earth's surface, contributing to warming. Water vapor, as the most abundant greenhouse gas, can amplify the greenhouse effect when its concentration increases due to a warmer atmosphere, leading to further warming of the climate system.</p> Signup and view all the answers
