State of the Climate in Asia 2024

The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …

For a pilot project on deep sea storage of CO2

Wallace S. Broecker One of the world's leading climate scientists challenges Greenpeace's opposition to storing CO2in the depth of the oceans. Most of us who are concerned about global warming agree that an important part of any strategy designed to stem the ongoing build-up of greenhouse gases in the atmosphere …

Improved estimates of upper-ocean warming and multi-decadal sea-level rise

Here the authors report improved estimates of near-global ocean heat content and thermal expansion for the upper 300m and 700m of the ocean for 1950

EU Court Dismisses Challenge To Sea Pollution Laws

The European Union is entitled to set tougher standards and criminal penalties on sea pollution than measures included in international conventions, the EU's highest court said on Tuesday. The European Court of Justice dismissed a challenge to the 27-nation bloc's marine pollution laws by an international coalition of ship operators. …

In Singapore, garbage island rises from the sea

Singapore: Once there was a dirty bit of sea next to the world's busiest port here. Today it is an island where birds nest and people play, though the entire island is made of rubbish. You wouldn't know unless you were told. There's no sight or smell at Semakau landfill …

Rising ocean acidity threatens islands

Rising acidity in the ocean caused by seas absorbing greenhouse carbon dioxide could make low-lying island nations like Kiribati and the Maldives more vulnerable to storms as their coral reefs struggle to survive, say scientists. Carbon dioxide in the atmosphere is at its highest level in the past 650,000 years …

Stemming decline of the coastal ocean: rethinking environmental management

The coastal marine environment provides enormous value in fishery and other products and in ecosystem services including coastal protection, water purification, and appropriate locations for ports, harbors, urban centers, tourist destinations, and numerous recreational pursuits. Current management practices are ineffective and to continue them will endanger coastal economies and ecosystems …

Marinoan meltdown

The termination of the Marinoan glaciation 635 million years ago is one of the most spectacular climate change events ever recorded. Methane release from equatorial permafrost might have triggered this global meltdown.

Atlantic cooling may be temporary respite

even though the earth is heating up there could be some relief, say recent studies. And we have to thank the Atlantic Ocean for this respite. Researchers at Leibniz Institute of Marine Sciences, Kiel, Germany, who studied the Atlantic say the ocean's natural phenomenon could slow down global warming. The …

No breaks for the Arctic

While studies indicate that global temperatures may not increase over the next decade, there is no respite for the Arctic sea ice, this year at least. There are very high chances, about 60 per cent, that the ice may shrink below the record minimum seen last year, says a press …

rat find: A team of scientists has rediscovered the greater dwarf cloud rat (Carpomys melanurus), last seen 112 years ago. It was in the canopy of a large tree, on a large horizontal branch covered by a thick layer of moss, orchids, and ferns, about five metres above ground at …

A large discontinuity in the mid-twentieth century in observed global-mean surface temperature

Data sets used to monitor the Earth's climate indicate that the surface of the Earth warmed from 1910 to 1940, cooled slightly from 1940 to 1970, and then warmed markedly from 1970 onward. The weak cooling apparent in the middle part of the century has been interpreted in the context …

Snowball Earth termination by destabilization of equatorial permafrost methane clathrate

Authigenic carbonates within the Reynella Member of the glacial Elatina Formation occur in coastal cliff exposures of the Marinoan type section in South Australia and provide constraints on the magnitude and timing of methane influence during deglaciation.

Climate anomaly is an artefact

The humble bucket turns out to be at the bottom of a perplexing anomaly in the climate records for the twentieth century. The time series of land and ocean temperature measurements, begun in 1860, shows a strange cooling of about 0.3

To stop your CO2 emission, bury it

Millions Of Tonnes Buried By Norwegian Platform Sleipner Platform: With planet Earth engaged in a heated race against global warming, "carbon capture and storage' (CCS) has brought a ray of hope, and a Norwegian gas platform is leading the way. The Sleipner platform in the North Sea, a mammoth steel …

Marine calcifiers in a high-CO2 ocean

New results show that the response of marine organisms to ocean acidification varies both within and between species.

A sprinkle of limestone could help oceans absorb CO2

Grind it down, pour in a sprinkle here and a dash there, and wait for results. That's the recipe for helping the oceans to absorb more of our carbon dioxide emissions: add limestone. It may not only help reduce global warming but could even reinvigorate ailing coral reefs.

Impacts of atmospheric anthropogenic nitrogen on the open ocean

Increasing quantities of atmospheric anthropogenic fixed nitrogen entering the open ocean could account for up to about a third of the ocean's external (nonrecycled) nitrogen supply and up to ~3% of the annual new marine biological production, ~0.3 petagram of carbon per year. This input could account for the production …

Study: Warming water means less oxygen for sea life

Low-oxygen zones where sea life is threatened or cannot survive are growing as the oceans are heated by global warming, a new study warns. Oxygen-depleted zones in the central and eastern equatorial Atlantic and equatorial Pacific oceans appear to have expanded over the last 50 years, researchers report in Friday's …

Global Warming Could Starve Oceans Of Oxygen - Study

Global warming could gradually starve parts of the tropical oceans of oxygen, damaging fisheries and coastal economies, a study showed on Thursday. Areas of the eastern Atlantic and Pacific Oceans with low amounts of dissolved oxygen have expanded in the past 50 years, apparently in line with rising temperatures, according …

Mother nature cools the greenhouse, but hotter times still lie ahead

A new paper shows that regional and even global temperatures are being temporarily held down by a natural jostling of the climate system, driven in large part by vacillating ocean currents.
