The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air. Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans.
The IPCC has introduced a new high-end risk scenario, stating that a global rise “approaching 2 m by 2100 and 5 m by 2150 under a very high greenhouse gas emissions scenario cannot be ruled out due to deep uncertainty in ice sheet processes.”. We would see massive coastalerosion happening all around. meters of rise by 2100.
The ocean has absorbed nearly 33% of all greenhouse gas emissions and around 90% of the excess heat produced through climate change. If you’re not on the water or near the coast, much of this price may go unnoticed until there are disasters like stronger hurricanes, more intense flooding, coastalerosion or harmful algal blooms.
Rivers, drinking water, and farmland in southern Senegal have become too salty, a consequence of coastalerosion and seawater intrusion. Coastal communities in southern Senegal are reckoning with environmental change. In Tunisia, scarce water reserves prompt nightly shutoffs in and around the capital city.
The increased intensity of storm surges coupled with the ineffectiveness of the coral reef barrier is leading to considerable coastalerosion in the Pacific Islands. Coastalerosion is occurring at an alarming rate within the Pacific Islands. Coastal change in the Pacific Islands. 3] Gombos, M., 4] Houghton, J.,
However, its authors leave a glimmer of hope in what could be a nod to governments ahead of COP26, that strong and sustained CO2 emissions reductions, as well as cuts to other planet-warming greenhouse gasses (GHG), would limit climate change. It is clear that keeping global warming to 1.5°C
This is undoubtedly the most significant finding of the judgment as the Court specifies that each Contracting State must undertake measures for the substantial and progressive reduction of their respective greenhouse gas (GHG) emission levels, with a view to reaching net neutrality within, in principle, the next three decades (para.
The Governor articulated in the legislation, “that Hawaii’s natural environment faces significant pressure from climate change and the heavy use it receives from persons traveling to enjoy the State’s natural resources.
To offset emissions, cultivated seaweed could be used to replace more greenhouse gas-intensive products, or could be sunk in the deep sea. Dense seaweed areas may be able to protect other organisms from ocean acidification, can provide oxygen-rich habitats, and can buffer against coastalerosion.
