Cambio climático: calentamiento global

The Earth's climate is warming, affecting oceans, land, and atmosphere. Over the past century, temperatures have risen significantly, with rapid warming in recent years. This is evidenced by melting glaciers and longer growing seasons. Global warming raises concerns about its impact on life, including food production and biodiversity. Climate change is linked to more frequent and severe storms, rising sea levels, and potential flooding of coastal areas. These changes may intensify over time, affecting future generations.

• Melting of glaciers

• Thickening of ice sheets

• Expansion of deserts

• Increase in snowfall

How has the growing season been affected by climate change?

• It has become unpredictable

• It has lengthened

• It remains unchanged

• It has shortened

What potential impact does climate change have on food production?

• It will have no impact

• It could change how and where food is grown

• It will increase food production everywhere

• It will only affect aquatic food sources

What is a possible consequence of rising sea levels?

• Expansion of polar ice sheets

• Decrease in ocean salinity
