My top 3 impressions up-front: The sealevel projections for the year 2100 have been adjusted upwards again. The IPCC gives more consideration to the large long-term sea-level rise beyond the year 2100. And here is the key sea-level graphic from the Summary for Policy Makers: Source: IPCC AR6, Figure SPM.8.
Deforestation and forest fragmentation are making it harder for species to move in response to climate chnage. Some marine species also experience boundaries to movement, including ocean currents, thermoclines, and shipping lanes, but they are generally more able to track changes in sea temperatures.

that the sea surface temperature there in winter is a good index of AMOC strength, based on a high-resolution climate model. Not in summer when the ocean is covered by a shallow surface mixed layer heated by the sun and highly dependent on weather conditions.) We argued in Caesar et al. The reanalysis data show the latter is the case.
In particular, he said, “reliance upon coal, on the other hand, could aggravate the ‘greenhouse effect,’ whereby excess carbon dioxide (which accompanies coal burning) traps heat inside the earth’s atmosphere, thus possibly melting the icecaps and raising the level of the oceans.”
Some of those predicted changes are already happening such as continued sealevel rise which is now irreversible over a time span of hundreds to thousands of years. And by the end of this century, extreme sea-level events which previously occurred every 100 years could happen every year. What’s to come.
Warmer temperatures will encourage the melting of glaciers, ice fields, summer Arctic sea ice, and permafrost, some of which may be irreversible. Sealevels will continue to rise throughout the 21st century, contributing to more frequent and severe coastal flooding in low-lying areas along coasts around the world.
From the ocean oscillations to trade winds, pressure systems that drives temperature, airborne particles that influence local conditions and even the phases of the moon and Earth's wobble all affect the climate (1). The east of the ocean is colder than normal while the west is warmer than average. What Climatology Is.
SIDS face a range of risks, including extreme floods, storms, droughts, unpredictability of precipitation patterns and sea-level rise, ocean acidification and deoxygenation (World Health Organization, 2018; Douglas & Cooper, 2020, Thomas, 2020). Small Islands, Large Oceans: Voices on the Frontlines of Climate Change.
Acidification : Reducing the pH rating of a substance making it more acidic in nature, for example, increased carbon emissions lead to the oceans absorbing more of it, increasing acidification and damaging ecology such as coral bleaching. We are already seeing the depletion of the ice caps and rising sealevels. For Ecology.
Plaintiffs aim to hold the federal government accountable for worsening the dangers of climate change through increased reliance on fossil fuels and for breach of its fiduciary obligation to protect the atmosphere and oceans under the public trust doctrine. It has also inspired landmark decisions in climate protection on a global scale.
The court stated: “Plaintiffs’ claims for public nuisance, though pled as state-law claims, depend on a global complex of geophysical cause and effect involving all nations of the planet (and the oceans and atmosphere). It necessarily involves the relationships between the United States and all other nations. BP p.l.c. , 18-cv-182 (S.D.N.Y.
The California Court of Appeal upheld conditions imposed by the California Coastal Commission on the construction of a single-family residence on a bluff adjacent to the Pacific Ocean in the City of Encinitas. Brazilian Court Granted a Preliminary Injunction Ordering the Removal of Cattle Herds from Farms that Caused Deforestation.

The full Senate also confirmed Monica Medina to be assistant secretary of state for oceans and international environmental and scientific affairs by a 61-36 vote.
