Impending Crisis: By 2100, 66% of the Global Population to Face Water Scarcity

A new study anticipates a worsening global water scarcity scenario, projecting that by 2100, as much as 66% of the population could be impacted, particularly in regions of the Global South. This highlights the urgent necessity to address both the quantity and quality of water in forthcoming water management strategies. Conducted by researchers at Utrecht […]

Protein-Fortified Microalgae Gets a Nutritional Lift from an Unexpected Source

In the pursuit of eco-friendly protein sources surpassing traditional livestock, insects and microalgae emerge as leading contenders. Recently, scientists have developed a technique that utilizes waste from insects as nourishment for microalgae. The United Nations’ Food and Agricultural Organization highlights that meat production contributes to roughly 14.5% of worldwide greenhouse gas emissions. These emissions primarily

Giant Iceberg Calves Off in Major Event in Antarctica

Climatology, Earth Science, Environmental Science / Jorge Paka

On May 20th, 2024, a 380 square kilometer (~147 mi²) iceberg separated from the Brunt Ice Shelf in Antarctica. This event, known as A-83, marks the third major iceberg calving in this area in the last four years. In 2021, the first significant event occurred when A-74 separated from the ice sheet, followed by an

The Largest Antarctic Ice Shelf is Acting Unusually

Climatology, Earth Science, Environmental Science / Jorge Paka

In Antarctica, massive glaciers are constantly shifting, with ice streams acting like conveyor belts that transport most of the ice and sediment debris from these glaciers to the ocean. According to new research from Washington University in St. Louis, one such ice stream displaces the entire Ross Ice Shelf at least once daily. This is

Alaska’s Colorful Rivers are Rapidly Growing, and We’ve Discovered Why

Earth Science, Environmental Science, Science / Jorge Paka

For the first time, a large team of North American scientists has mapped Alaska’s ‘rusting’ rivers and streams, tracking 75 areas in the remote Brooks Range. These rivers have a bright, unusual hue visible even from space. Researchers from the National Park Service (NPS), US Geological Survey, University of California, Davis (UC Davis), and other

Major Meta-Study Confirms the Effectiveness of Carbon Pricing

Climatology, Earth Science, Environmental Science, Science / Jorge Paka

Carbon pricing systems have empirically reduced emissions by 5 to 21% in their initial years of operation. A research team has compiled findings from 17 real-world climate policies worldwide, offering a more comprehensive understanding than ever before. They employed artificial intelligence to consolidate existing surveys and made them comparable through a new calculation method. The

This Ancient Ice Block Unveils Current CO2 Levels

2 Comments / Earth Science, Environmental Science / Jorge Paka

Although there’s increasing evidence suggesting that we’re experiencing unparalleled levels of atmospheric greenhouse gases, our limited historical understanding has impeded our ability to contextualize current CO2 emissions over the long term. What if we could utilize the Earth’s natural historical records to fill in these crucial gaps? In a daring move, researchers from Oregon State

Earth’s Gateway to Hell Expands by 35 Million Cubic Feet Annually

Earth Science, Environmental Science, Science / Jorge Paka

Whether you admire John Carpenter’s creations or have a fascination with biology, the thawing of subterranean permafrost in polar areas presents notable apprehensions. In a recent discovery, researchers revealed a ‘zombie virus‘ dating back 48,500 years, extracted from Arctic permafrost, contributing to the mounting concerns linked with climate change. This new threat highlights the potential

Brazil Launches urgent Rescue Operation as Floods Kill Over 78

Climatology, Earth Science, Environmental Science, Science / Jorge Paka

Southern Brazil authorities worked urgently on Sunday to rescue individuals from severe floods and mudslides, marking the area’s worst-ever climate disaster. The calamity has resulted in a death toll of at least 78, with 115,000 individuals displaced from their residences. Entire cities found themselves submerged under floodwaters, isolating thousands of individuals due to days of

Research Identifies Early Signs of African Humid Period’s End

Earth Science, Environmental Science, Science / Jorge Paka

The shift from the African humid period (AHP) to arid conditions in North Africa stands out as a prominent example of climate tipping points in recent geological records. These tipping points occur when minor disturbances provoke significant, nonlinear reactions in the climate system, leading to a transition to a distinctly different climate state, often with
