Sea Level Rise
Sea Level Rise
The gradual increase in the average level of the Earth's oceans, driven by climate change.
Impact on Agriculture
Impact on Agriculture
Climate change negatively affects agriculture by reducing crop yields in many areas, increasing temperatures, altering precipitation, and more extreme weather events.
Threat to Biodiversity
Threat to Biodiversity
Climate change, along with other human actions, endangers the variety of life on Earth, including plants, animals, and other species.
Study Notes
Sea Level Rise
- Global sea levels have risen 8-9 inches since 1880
- Scientists predict a further rise of 1-8 feet by the end of the century
- The rate of rise varies based on coastal geography, erosion and ocean currents
- Sea level rise is a concern for densely populated coastal regions.
- Many major cities (e.g., Jakarta, Bangkok) are at risk from rising seas and flooding.
- "Sunny-day flooding" is already affecting some coastal areas
Impacts on Agriculture
- Climate change impacts crop yields globally
- Crop yields are projected to decline in many regions
- Rising temperatures, changing precipitation, and extreme weather reduce crop yields
- Increased carbon dioxide reduces the nutrient levels in key crops (e.g., zinc, iron, protein, vitamins) in staple crops
- Some regions may see increases, but these are outweighed by projected decreases.
Biodiversity Threats
- Climate change, combined with pollution, threatens biodiversity.
- Increased temperatures and altered precipitation patterns make it hard for species to adapt
- Loss of biodiversity could lead to extinctions of animal and plant species.
- 1 million animal and plant species are threatened.
