A new study explores the impact of sun dimming on atmospheric teleconnections, which are crucial for predicting weather regimes. The research suggests that a dimmed sun could alter the link between tropical temperatures and extra-tropical circulation, potentially affecting prevailing weather patterns.
A new study by University of Bristol researchers reveals that geoengineering would have varying impacts globally. Regions like the USA and Australia become drier with increasing strength, while others like Australia become wetter.
A University of Calgary scientist proposes two novel geoengineering approaches to mitigate global warming: releasing engineered nano-particles and sulphuric acid. These methods aim to reduce the negative effects of sulphates, which are blunt instruments for climate engineering.
A new study suggests that seeding clouds over the ocean to make them more reflective could actually increase monsoonal rains and cause continents to become wetter on average. This contradicts previous assumptions about the impact of geoengineering schemes on global rainfall patterns.
Researchers found that introducing aerosols into the model made clouds significantly more reflective, but only in certain situations. The team also tested when to spray seawater aerosols to maximize brightness.
A new study by John Anderson of the Nevada Seismological Laboratory has compiled a list of 100 earthquakes with the strongest peak accelerations (PGA) and velocities (PGV) ever recorded, exceeding thresholds of 7.31 m/s2 for acceleration and 0.65 m/s for velocity.
Experts Peter Cox and Hazel Jeffrey examine potential geoengineering initiatives, including carbon-dioxide removal and solar-radiation management, as a crucial alternative to common mitigation methods. The schemes have different benefits, costs, and risks associated, but may offer a better benefit-to-cost ratio than conventional methods.
New research suggests geoengineering techniques may cause more harm than good due to uncertainties in their effects on Earth's natural cycles. Ecologists debate the viability of geoengineering methods like atmospheric seeding and ocean fertilization, highlighting potential risks such as ozone depletion and dead zones in oceans.
A new study found that geoengineering solutions to counter global warming would have a minimal impact on ocean acidification, which threatens coral reefs and marine life. Reducing carbon dioxide emissions is considered a more effective safeguard against climate change.
Researchers at the University of East Anglia evaluated 12 geoengineering schemes and found that stratospheric aerosol injections and sunshades in space have the greatest potential to cool the climate. However, these schemes also carry significant risks.
A team of researchers found that magma is continuously supplied from deep in the crust but a valve acts below a shallower magma chamber, releasing lava to the surface periodically. The upper reservoir is open and the lower reservoir refills at half the rate it was lost during lulls in eruption.
A new study suggests that geoengineering schemes could lead to a decline in the intensity of the global water cycle. The research found that reducing sunlight through
New research suggests that injecting sulfate particles into the stratosphere to cool the planet would have a drastic impact on the ozone layer. The study finds that such an approach might delay the recovery of the Antarctic ozone hole by decades and cause significant ozone loss over the Arctic.
A new computer modeling study suggests geoengineering schemes could cool the planet within a few decades, but failure or cancellation could lead to catastrophic temperature spikes. The research highlights the need for careful consideration of these strategies.
