Sea level in the IPCC 6th assessment report (AR6)

Real Climate

My top 3 impressions up-front: The sea level 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.

Celebrating World Ocean Day

Law and Environment

The ocean covers 71% of the planet and holds nearly 97% of the Earth’s water, and about 40% of the world’s population lives within 100 kilometers of the coastline. What is Bluetech? Spotlight on SeaAhead.

The water south of Greenland has been cooling, so what causes that?

Real Climate

Sea surface temperature trend 1993 – 2018, from European Atlas of the Seas. Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces. Let’s compare two possibilities by a back-of-envelope calculation. (1) Greenland ice melt.

2023 appears to follow an upward trend in the North Atlantic/Caribbean named tropical cyclone count

Real Climate

It’s an interesting situation if there are different trends for all tropical cyclones on the one hand and the most intense ones on the other, or if there are trends that point in different directions over different ocean basins. 2023) observed a significant seasonal advance of intense tropical cyclones since the 1980s in most tropical oceans.

The AMOC: tipping this century, or not?

Real Climate

So the Ditlevsens used sea surface temperatures (SST) in a region between the tip of Greenland and Britain as an indicator, based on Caesar et al. 2018 ( PDF ; I’m a coauthor on that paper). that the sea surface temperature there in winter is a good index of AMOC strength, based on a high-resolution climate model.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

There is no doubt that we have changed Earth’s climate through our activities on a broad range of aspects that includes consequences for the atmosphere, the oceans, snow, ice, Earth’s fauna and ecosystems. CO 2 also has an additional effect: it makes the oceans more acidic when dissolved in seawater. mm increase every year.

Degradation of coastal regions in the Pacific Islands

Our Environment

Rising sea levels and increased intensity of storm surges are playing a considerable role in the degradation of coastal regions in the Pacific Islands. Illustrating the variation in sea levels from 1993 – 2018. Source: NASA (August 2018). Photo credit. Written by: Jack McCulloch. should be. [4]
