Today, we'll distinguish between climate and weather. Remember, 'Climate is what we expect; weather is what we get.' Can anyone tell me how they would prepare differently for climate vs. weather?
If it's winter and I know it will be cold in Minnesota, I would buy heavier clothes for the climate.
But for the weather, I would check the forecast and decide if I need an umbrella today or not!
Exactly! Climate gives you an idea for long-term preparations, while weather is more immediate. Let's remember it as C for Climate and W for Weather.
So, climate is like planning for a trip, and weather is checking what to wear on that trip?
Great analogy! Now, let’s explore how these definitions lead into understanding seasonal variance.
As climate change progresses, we observe shifts in seasonal variance. For example, what do you think happens to regions like Scandinavia that used to have distinct seasons?
I've heard it's changing! There's less snow now, isn’t there?
Absolutely! Snow cover has reduced from 8 months to just 6 months. This is because climate change is causing gradual warming. Can anyone think of why that matters for plants and animals?
Animals rely on the seasons for food and habitat. If seasons blend, won't it confuse them?
Yes! It can lead to habitat loss and even extinction of certain species. This highlights how interconnected our ecosystems are.
Now let's touch on the global temperature rise. An increase of just 1 degree Celsius can have vast impacts—what are some?
I think it would melt glaciers and raise sea levels, but what other effects?
Great point! It affects ocean temperatures, which can lead to extreme weather patterns! Can you see how that's a concern?
Yes, and it affects biodiversity too! Maybe certain birds won't migrate correctly anymore.
Exactly! This intricate web of interdependencies shows the importance of understanding these changes for effective planning.
Long-term atmospheric patterns in a region.
Short-term atmospheric conditions.
Changes in season characteristics due to climate change.
Effects of rising global temperatures on weather patterns, ecology, and human systems.
Emissions that contribute to the greenhouse effect.
Weather can surprise, like rain in mid-July, climate is steady, like seasons passing by.
Imagine a bird that prepares for winter; each season it migrates, but if winter doesn’t come, it struggles to find food. This shows how vital distinct seasons are.
C - Climate is long-term, W - Weather is short-term, S - Seasons can vary; remember which is which!

The long-term heating of Earth’s climate system due to human activities.
Gases in the atmosphere that trap heat, contributing to global warming.
This section explores how climate change affects seasonal variance, impacting the environments of various geographic areas.
The section emphasizes the distinction between climate and weather, elucidating how changes in global temperatures due to climate change are reducing seasonality, with significant implications for biological, ecological, and human systems.
The section discusses the impact of climate change on seasonal variance. It begins with the distinction between climate, defined as the average weather conditions over a long period in a specific area, and weather, which is the day-to-day state of the atmosphere. The teacher explains the effects of global temperature increases, which have risen by approximately 1 degree Celsius, on seasonal patterns. There is a notable reduction in seasonality across regions, illustrated through a comparison of current conditions in locations like Scandinavia—a shift from 8 to 6 months of snow cover
The conclusion emphasizes the need for understanding these changes to develop strategies for adaptation and mitigation, crucial for disaster management and urban planning in the face of climate change.
