Climate Change and the Oceans

Friday, December 15 ยท 10 – 11:30am

Join us for another talk from Ian Hawker, leader of East Suffolk u3a’s Climate Change group.

71% of the worlds surface is covered by oceans which moderate climate change, capturing 90% excess heat from the atmosphere, and absorbing 1/3 excess greenhouse gas emissions.

But this also warms the oceans producing Arctic Ice Disintegration, Antarctic Ice Melting, Sea Level Rise and Ocean Acidification.

Exploitation of ocean resources is also affected by climate change. For example Ocean food stocks will reduce as the water warms so that more efficient sea farming methods are needed.

Sea Mining of minerals produces ocean pollution, through disturbance of the sea floor, and currently faces a global embargo pending further investigation.

However, extraction of tidal energy using new technologies will help replace fossil fuels.

Based on Feedback, this talk will be 60 minutes, with 30 minutes for questions.
