The timing of Earth’s biggest volcanic episodes was governed by the slowing of continental plate movement.

Earth Sciences Article
Researchers have revealed new insight into the timing and logical reason for major volcanic occasions that happened great many quite a while back and created such climatic and natural commotion that they drove probably the most crushing elimination occasions in Earth's set of experiences. Shockingly, the new exploration, distributed today in Science Advances, proposes an easing back of mainland plate development was the basic occasion that empowered magma to ascend to the World's surface and convey the staggering thump on influences. Earth's set of experiences has been set apart by major volcanic occasions, called huge molten areas (LIPs) — the

Earth’s Core-mantle Boundary Contains Rust and Diamonds

Earth Sciences News
Scientists discover that a potential 'diamond factory' may have existed at Earth's core-mantle boundary for billions of years. Steel rusts by water and air on the Earth's surface. But what about deep inside the Earth's interior? The Earth's core is the largest carbon storage on Earth - roughly 90% is buried there. Scientists have shown that the oceanic crust that sits on top of tectonic plates and falls into the interior, through subduction, contains hydrous minerals and can sometimes descend all the way to the core-mantle boundary. The temperature at the core-mantle boundary is at least twice as hot as

New seabed pictures from the West Antarctic Ice Sheet challenge previous theories of Thwaites Glacier retreat.

Earth Sciences Article
The Thwaites Glacier in West Antarctica, which is roughly the size of Florida, has been a major concern for researchers attempting to meet global ocean level rise expectations. This monstrous ice stream is as of now in a period of quick retreat (a "breakdown" when seen on land timescales), prompting boundless worry about precisely how much, or how quickly, it might surrender its ice to the sea. The likely effect of Thwaites' retreat is spine-cooling: a complete loss of the icy mass and encompassing cold bowls could raise ocean level by 3 to 10 feet.

By 2050, Climate Change will have more than Doubled the Risk of Severe Tropical Cyclones

Earth Sciences News
The atmosphere is becoming more hostile to the formation of tropical cyclones as a result of global warming. By the early 2010s, there were approximately 13% fewer storms across all oceans than in the late 1800s. Climate change has resulted in a 13% decrease in the frequency of tropical cyclones since pre-industrial times, according to new research. According to a new study published in Scientific Advances, human-caused climate change will make strong tropical cyclones twice as common by the middle of the century, putting large parts of the world at risk. According to the analysis, maximum wind speeds associated with

Food production has an influence on the Earth’s natural systems.

Earth Sciences Article
Food creation is now one of the greatest stressors to our planet, yet it's made considerably more testing by the connection of Earth's framework processes, as per new examination. Earth's framework processes allude to the normal exercises that keep the planet in a tenable and helpful state. This includes processes occurring in various biospheres, such as carbon sequestration in forests and supplement runoff into freshwater frameworks. The connections between these cycles challenge their limits and impact how well they capability. "Food creation is a significant reason for natural pressure, influencing biodiversity misfortune, the environment, and overexploitation of marine assets," co-creator

Where Coral Reefs may act as a buffer against rising Ocean Temperatures

Earth Sciences News
Scientists at the National Center for Atmospheric Research (NCAR) have successfully used an extremely high-resolution computer simulation of ocean circulation to identify possible "thermal refugia" where these biodiverse ecosystems are more likely to survive as ocean temperatures rise. The research team has created an interactive, freely accessible online global atlas that shows the locations of these areas, where ocean dynamics and cooler waters combine to provide potential havens for coral reefs. "We hope that this work serves as a starting point for other scientists interested in reefs," said NCAR scientist Scott Bachman, who led the new study, which was published

Eruption of Volcano will aid Scientists in Forecasting Weather and Climate

Earth Sciences News
Volcanoes can have an impact on climate change. Massive amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere during major explosive eruptions. Injected ash falls rapidly from the stratosphere, with most of it being removed within days to weeks, and has little effect on climate change. However, volcanic gases such as sulfur dioxide have the potential to cause global cooling, whereas volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming. The January eruption of the Hunga Tonga-Hunga Ha'apai volcano gave scientists a once-in-a-lifetime opportunity to study how the atmosphere works, unlocking keys

A New Model reveals that Earth’s Deep Mantle was Dry from the Beginning

Earth Sciences News
A scientist determined that the ancient plume mantle (the deep part) had a water concentration that was 4 to 250 times lower than the upper mantle by analyzing noble gas isotope data. The Earth's mantle is a thick layer of silicate rock that lies between the planet's crust and its molten core, accounting for approximately 84 percent of its volume. On geologic time scales, the mantle is predominantly solid, but it behaves as a viscous fluid, making it as difficult to stir and mix as a pot of caramel. But, if you must make a candy comparison, consider malt balls

The Illumination of Perplexing features deep within Earth’s Interior

Earth Sciences News
The University of Cambridge led the first detailed image of an unusual pocket of rock at the boundary layer with Earth's core, some three thousand kilometers beneath the surface. The mysterious rock formation, which lies almost directly beneath the Hawaiian Islands, is one of several ultra-low velocity zones, so named because earthquake waves slow to a crawl as they pass through them. The study, which was published in Nature Communications, is the first to detail the complex internal variability of one of these pockets, shedding light on the landscape of Earth's deep interior and the processes that operate within it.

Bird Species are not only becoming Extinct, also lose the Characteristics that distinguish each Species

Earth Sciences News
Consider a world in which all birds have become extinct. Most of us would consider a spring morning devoid of birds singing and calling, or of feathered creatures soaring through the sky. If you've ever witnessed the miracle of a wild bird egg hatching, that may be the image you cherish and would miss if the world didn't have birds. Climate change is causing a mass extinction that has never been seen before in recorded history. This biodiversity loss has consequences for birds that go beyond species loss. In a study published in the journal Current Biology, researchers predict that
