Study Notes

SST in Climate Change and Geoscience

Sea surface temperature (SST) is a critical parameter in the ongoing conversation about climate change. It serves as a barometer for the health of our planet's oceans, and its fluctuations heavily influence global weather patterns, ecosystems, and the earth's energy balance.

SST and Climate Change

SSTs are rising globally due to climate change, with an average increase of about 0.13°C per decade from 1987 to 2018. This warming trend is driven by the greenhouse gases accumulating in the atmosphere, which trap heat and lead to an increase in global temperature. SSTs account for about 90% of the earth's additional heat storage during climate change.

SSTs play a crucial role in transforming climate change into tangible impacts on our planet. Warmer SSTs result in:

  • Intensification of storms. Warmer SSTs provide more energy for the development of tropical storms, such as hurricanes and typhoons.
  • Rising sea levels. Warmer water expands, and melting ice from polar regions contributes to the increase in sea levels.
  • Impact on marine ecosystems. Warmer SSTs can lead to shifts in ocean circulation, result in the expansion of certain species, and cause the decline or extinction of others.

Geoscience and SSTs

Understanding SSTs is fundamental to geoscience research. SSTs influence ocean currents and general circulation patterns, such as El Niño and La Niña, which can have a substantial impact on global weather and climate.

SSTs play a crucial role in the water cycle, as they determine the amount of water vapor the atmosphere can hold. Warmer SSTs lead to an increase in evaporation, and this water vapor helps fuel storms and precipitation patterns.

Instrumentation for measuring SSTs has advanced greatly over the years. Satellites have become a significant source of data, providing global coverage and high temporal resolution. In-situ observations, such as buoys and Argo floats, also contribute to our understanding of SSTs.

Future Challenges and Conclusion

As climate change continues to intensify, SSTs will remain a critical parameter in understanding and predicting our planet's future. The interactions between SSTs and other elements of the climate system will require a continued focus on research, monitoring, and collaboration between scientists from various disciplines.

The consequences of rising SSTs are already evident, such as the increase in extreme weather events and the bleaching of coral reefs. The challenge for scientists, policymakers, and society as a whole is to develop adaptive strategies to manage these impacts and mitigate the effects of climate change. Understanding SSTs and their role in the climate system will be vital in meeting this challenge.

In summary, SSTs have a profound impact on our planet's climate and its ecosystems. As the global temperature continues to increase, understanding and monitoring SSTs will be crucial to our efforts to address the challenges posed by climate change.
