16 Questions

What is the main reason for the decrease in snowfall events globally?

Rising temperatures due to climate change

What is contributing to the warming of winter at a faster rate than any other season in the U.S.?

Earth's heating up and this year’s El Niño

How has winter precipitation been affected according to the text?

More commonly falling as raindrops than snow

What has the Nature study confirmed about the Northern Hemisphere’s snowpacks since the 1980s?

They have shrunk due to climate change

What is a likely consequence of a warmer world that has lower likelihood of snow?

Need to go higher up a mountain to find snow

According to Liz Bentley, what has been the trend in terms of snowfall events globally?

Decreasing because temperatures are going up

What could happen if global emissions are not curbed by 2100?

Snow-free winters in a large portion of the world

How does climate change impact the process of creating snow?

By making the planet hotter and increasing moisture in the atmosphere

Why might snow dumps be used as proof that climate change isn't happening?

Because they are seen as a symptom of the larger climate problem

How does reduced snowfall impact wildlife?

It may lead to the extinction of some animals

What process do trees undergo to release water into the atmosphere?

Evapotranspiration

Why is less snowfall problematic for humans?

It affects water security as snow supplies a significant amount of drinking water

What happens when there hasn't been much snow according to Andrew Schwartz?

"When a fire does spark, it runs away as fast as possible and burns as much area as it can"

How does more extreme weather conditions affect precipitation?

"More extreme conditions create large swings between extremes"

"The wet gets wetter and the dry gets drier" refers to what phenomenon according to James Screen?

"The phenomenon of larger swings between wet and dry conditions"

"Snow on the mountains acts like a natural reservoir" implies what function of snow?

"Snow functions as a natural water storage system"

Study Notes

Global Snowfall Decrease

  • Decrease in snowfall events globally due to warming winters
  • Winters warming faster than any other season in the U.S.

Winter Precipitation

  • Winter precipitation affected, with reduced snowfall events
  • Less snowfall leads to lower likelihood of snow

Northern Hemisphere's Snowpacks

  • Nature study confirms decline of Northern Hemisphere's snowpacks since the 1980s

Consequences of Warmer World

  • Warmer world with lower likelihood of snow leads to negative consequences
  • If global emissions not curbed by 2100, catastrophic consequences likely

Global Snowfall Trends

  • Liz Bentley: global snowfall events decreasing

Climate Change and Snow

  • Climate change alters process of creating snow
  • Snow dumps may be misinterpreted as proof that climate change isn't happening

Impact on Wildlife

  • Reduced snowfall affects wildlife negatively

Tree Water Release

  • Trees release water into atmosphere through transpiration

Human Consequences

  • Less snowfall problematic for humans, especially for water supply
  • Andrew Schwartz: lack of snow leads to drought and water scarcity

Extreme Weather

  • More extreme weather conditions lead to altered precipitation patterns

Precipitation Phenomenon

  • "The wet gets wetter and the dry gets drier" refers to altered precipitation patterns

Snow Reservoir Function

  • Snow on mountains acts like a natural reservoir, regulating water supply

Explore the changing winter weather patterns and the impact of global warming on snowfall and precipitation. Understand how the planet's warming is affecting winter seasons around the world.
