Question
Sea level will rise and some coastal cities may be submerged.
“The land is part of me...”
"The future kind of scares me, just thinking about how we're going to survive." says 18-year old Harlie Potter, an Inuit living in the autonomous area of Nunatsiavut in Newfoundland, Canada. Today, warming is most noticeable in the polar regions, especially in the Arctic.
How Will Climate Change in the Future?
Earth’s temperature will keep rising unless greenhouse gas emissions are curbed. The temperature in 2100 may be as much as 5° C (9° F) higher than it was in 2000. Is 5° C (9° F) a lot? It's more than the increase in temperature from the the times of maximum ice during the Pleistocene to now. Since the end of the Pleistocene, the temperature has only risen about 4° C. That's just 4° C from abundant ice to the moderate climate we have today. How might a 5° C increase in temperature affect Earth in the future?
Warming will affect the entire globe by the end of this century. The map in Figure below shows how much temperatures will change by 2050 based on NOAA’s Coupled Climate 2.1 model. The Arctic and inland areas are predicted to see a higher temperature increase, while the temperature increase in coastal areas and the Southern Ocean are likely to be more moderate.

[Figure 2]
The Arctic will experience the greatest temperature changes.
What Will Happen?
As temperature rises, more sea ice will melt. The figure below shows how much less sea ice there may be in 2050 if temperatures keep going up (Figure below). This would cause sea level to rise even higher. Some coastal cities could be under water. Millions of people would have to move inland. How might other living things be affected?

[Figure 3]
In the 2050s, there may be only half as much sea ice as there was in the 1950s.
Weather will become more extreme. Heat waves and droughts will become more frequent and more intense. Areas that previously were humid, like the Amazon rainforest, will become drier. Cropland worldwide will be affected by drought. Other places may flood more frequently as hurricanes and other storms become more severe.
Plants and animals will move or die out. Some will thrive in a warmer world, but most will not. The biosphere may become quite different.
These are only a few of the impacts warmer temperatures will have. The vast majority of scientists agree that this is what is happening

and that immediate action is necessary to mitigate the effects of climate change. The potential consequences of a 5° C increase in temperature are staggering and can reshape our planet and life as we know it.
### Key Impacts of Rising Temperatures
1. **Melting Ice and Rising Sea Levels**:
- The continued melting of polar ice caps and glaciers will contribute to rising sea levels. If significant amounts of ice, particularly in Greenland and Antarctica, melt, we could see several feet of sea-level rise over the coming decades. This would inundate coastal cities and habitats, forcing millions of people to relocate and leading to significant economic disruptions.
2. **Extreme Weather Events**:
- Increased temperatures are linked to more intense and frequent weather events. Heatwaves could become commonplace, particularly in areas that traditionally experienced milder climates. Additionally, hurricanes and storms are likely to become stronger, bringing heavier rainfall and flooding to coastal communities.
3. **Ecosystem Disruption**:
- Changing temperatures will disrupt ecosystems worldwide. Some species may adapt to warmer climates, but many others will struggle to survive in altered habitats. This could lead to significant biodiversity loss as species either migrate to cooler areas or face extinction.
4. **Agricultural Challenges**:
- Rising temperatures and shifting weather patterns will impact agricultural productivity. Drought conditions may prevail in once fertile areas, reducing food supplies and increasing the risk of famine. Regions that depend on specific crops may become unviable, necessitating a shift in agricultural practices and crop varieties.
5. **Public Health Risks**:
- The increasing frequency of heatwaves and the spread of disease-carrying vectors like mosquitoes can pose serious public health risks. Vulnerable populations, such as the elderly and those with pre-existing health conditions, may face heightened danger from extreme temperatures and vector-borne diseases.
6. **Social and Economic Impacts**:
- The migration of populations away from affected areas will create humanitarian crises, with potential conflicts arising over resources like water and arable land. Economies that rely on coastal tourism or traditional agriculture may suffer greatly, necessitating adaptation strategies to cope with these transitions.
7. **Psychological Effects**:
- The fear and uncertainty surrounding climate change can lead to anxiety and despair, especially for younger generations who may face a reality significantly altered by these changes.
### Conclusion
The future painted by a potential 5° C increase in temperature is, indeed, alarming. However, it is essential to remember that the trajectory is not predetermined. Global coordination on reducing greenhouse gas emissions, investing in renewable energy sources, and promoting conservation can help mitigate the impacts of climate change. Community-led initiatives, government policies, and individual choices all play a role in influencing the future of our planet. Inaction is not an option; the time to act is now.
