Extreme fire weather in Chile driven by climate change and El Niño–Southern Oscillation (ENSO) - Scientific Reports
2024-01-23 in NatureA string of fierce fires broke out in Chile in the austral summer 2023, just six years after the record-breaking 2017 fire season. Favored by extreme weather conditions, fire activity has dramatically risen in recent years in this Andean country. A total of 1.7 million ha. burned during the last decade, tripling figures of the prior decade. Six of the seven most destructive fire seasons on record occurred since 2014. Here, we analyze the progression during the last two decades of the weather conditions associated with increased fire risk in Central Chile (30°–39° S). Fire weather conditions (including high temperat...

Robust acceleration of Earth system heating observed over the past six decades - Scientific Reports
2024-01-02 (or before) in NatureGlobal heating of the Earth system is unequivocal. However, detecting an acceleration of Earth heating has remained elusive to date, despite suggestive evidence of a potential increase in heating rates. In this study, we demonstrate that since 1960, the warming of the world ocean has accelerated at a relatively consistent pace of 0.15 ± 0.05 (W/m2)/decade, while the land, cryosphere, and atmosphere have exhibited an accelerated pace of 0.013 ± 0.003 (W/m2)/decade. This has led to a substantial increase in ocean warming, with a magnitude of 0.91 ± 0.80 W/m2 between th...

Will the Globe Encounter the Warmest Winter after the Hottest Summer in 2023? - Advances in Atmospheric Sciences

The consecutive record-breaking mean surface temperature has caused many to speculate upon how the global temperature will evolve in the coming 2023/24 boreal winter. In this report, as shown in the multi-model ensemble mean (MME) prediction released by the Institute of Atmospheric Physics at the Chinese Academy of Sciences, a medium-to-strong eastern Pacific El Niño event will reach its mature phase in the following 2–3 months, which tends to excite an anomalous anticyclone over the western Nort...

Estimating the impact of new high seas activities on the environment: the effects of ocean-surface macroplastic removal on sea surface ecosystems
2023-11-21 (or before) in PeerJThe open ocean beyond national jurisdiction covers nearly half of Earth’s surface and is largely unexplored. It is also an emerging frontier for new types of human activity. Understanding how new activities interact with high seas ecosystems is critical for our management of this other half of Earth. Using The Ocean Cleanup (TOC) as a model, we demonstrate why it is important to account for uncertainty when assessing and evaluating impacts of novel high seas activities on marine ecosystems. TOC’s aim is to remove plastic from the ocean surface by collecting it with large nets. However, this approach also results in t...

Ocean circulation and climate during the past 120,000 years - Nature
2023-07-28 (or before) in NatureOceans cover more than two-thirds of our blue planet. The waters move in a global circulation system, driven by subtle density differences and transporting huge amounts of heat. Ocean circulation is thus an active and highly nonlinear player in the global climate game. Increasingly clear evidence implicates ocean circulation in abrupt and dramatic climate shifts, such as sudden temperature changes in Greenland on the order of 5–10 °C and massive surges of icebergs into the North Atlantic Ocean — events that have occurred repeatedly during the last glacial cycle.

Impacts on cloud radiative effects induced by coexisting aerosols converted from international shipping and maritime DMS emissions
2023-07-05 (or before) in ACP - Atmospheric Chemistry and PhysicsAbstract. International shipping emissions (ISE), particularly sulfur dioxide, can influence the global radiation budget by interacting with clouds and radiation after being oxidized into sulfate aerosols. A better understanding of the uncertainties in estimating the cloud radiative effects (CREs) of ISE is of great importance in climate science. Many international shipping tracks cover oceans with substantial natural dimethyl sulfide (DMS) emissions. The interplay between these two major aerosol sources on CREs over vast oceanic regions with a relatively low aerosol concentration is an intriguing yet poorly addressed issue conf...

2023-06-01 (or before) in NatureAnthropogenic aerosols mask the climate warming caused by greenhouse gases (GHGs). In the absence of observational constraints, large uncertainties plague the estimates of this masking effect. Here we used the abrupt reduction in anthropogenic emissions observed during the COVID-19 societal slow-down to characterize the aerosol masking effect over South Asia. During this period, the aerosol loading decreased substantially and our observations reveal that the magnitude of this aerosol demasking corresponds to nearly three-fourths of the CO2-induced radiative forcing over South Asia. Concurrent measurements over the northern India...

It’s Happened Before: Paleoclimate Study Shows Warming Oceans Could Lead to a Spike in Seabed Methane Emissions - Inside Climate News

Cold temperatures and high pressure on sea floors currently sequester about one-sixth of the world’s methane, a potent but short-lived greenhouse gas, in an ice-like form […]

Antarctica's ice shelves could be melting faster than we thought
2022-08-14 (or before) in Phys.org - News and Articles on Science and TechnologyA new model developed by Caltech and JPL researchers suggests that Antarctica's ice shelves may be melting at an accelerated rate, which could eventually contribute to more rapid sea level rise. The model accounts for an often-overlooked narrow ocean current along the Antarctic coast and simulates how rapidly flowing freshwater, melted from the ice shelves, can trap dense warm ocean water at the base of the ice, causing it to warm and melt even more.

On avoiding dangerous anthropogenic interference with the climate system: Formidable challenges ahead

The committed warming is inferred from the most recent Intergovernmental Panel on Climate Change (IPCC) estimates of the greenhouse forcing and climate sensitivity. The estimated warming of 2.4°C is the equilibrium warming above preindustrial temperatures that the world will observe even if GHG concentrations are held fixed at their 2005 concentration levels but without any other anthropogenic forc...

Few realistic scenarios left to limit global warming to 1.5°C
2021-05-16 (or before) in Science DailyOf the over 400 climate scenarios assessed in the 1.5°C report by the Intergovernmental Panel on Climate Change (IPCC), only around 50 scenarios avoid significantly overshooting 1.5°C. Of those only around 20 make realistic assumptions on mitigation options, for instance the rate and scale of carbon removal from the atmosphere or extent of tree planting, a new study shows. All 20 scenarios need to pull at least one mitigation lever at 'challenging' rather than 'reasonable' levels.

Burning fossil fuels helped drive Earth’s most massive extinction
2020-11-20 in Deccan HeraldPaleontologists call it the Permian-Triassic mass extinction, but it has another name: “the Great Dying.” It happened about 252 million years ago, and, over the course of just tens of thousands of years, 96% of all life in the oceans and, perhaps, roughly 70% of all land life vanished forever. The smoking gun was ancient volcanism in what is today Siberia, where volcanoes disgorged enough magma and lava over about a million years to cover an amount of land equivalent to a third or even half of the surface area of the United States.

Like many people, in the 1990s I believed 550 was the target needed to avoid climate catastrophe -- but now it's clear that: 550 ppm would lead to the greatest disaster ever experienced by human civilization -- returning us to temperatures last seen when sea levels were some 80 feet higher.
