Extreme Temperatures Raise Stroke Death Risk in Low-Income Countries

Climatology, Earth Science, Science / Ana Kiesse Zeleme

Extreme temperatures raise stroke death risk in low-income countries. Both extreme heat and cold are linked to higher death rates from ischemic and hemorrhagic strokes, as found in a new study by Harvard T.H. Chan School of Public Health. The connection between extreme temperatures and stroke deaths was more pronounced in low-income countries compared to […]

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

Volcanic Ash: Efficient and Budget-Friendly Solar Storage

Earth Science, Science, Volcanology / Jorge Paka

When a region finds itself covered in volcanic ash, it’s usually not a positive development. However, researchers from the University of Barcelona have uncovered a unique set of beneficial characteristics in volcanic ash, rendering it remarkably valuable as an energy storage medium. We’ve discussed both incredibly affordable thermal energy storage solutions and remarkably efficient heat

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

Human Activities have a Big Impact on Deep Subsurface Fluid Flow

Earth Science, Environmental Science, Geology / Jorge Paka

The effects of human activities, including greenhouse gas emissions and deforestation, on Earth’s surface have been extensively researched. Recently, hydrology experts from the University of Arizona delved into the influence of human actions on the deep subsurface of the Earth, an area located hundreds of meters to several kilometers below the surface. “We examined the

5 Corporations Responsible for 24% of Traceable Plastic Pollution

Earth Science, Environmental Science / Jorge Paka

A recent study revealed that nearly 25% of identifiable plastic pollution originates from just five large corporations. Analyzing 1.87 million instances of environmental plastic waste from 2018 to 2022, researchers found that over half of these instances couldn’t be attributed to any specific company. Furthermore, among the remaining plastic waste, 24% could be linked to
