Climate Change Poses Significant Risks to Wind Power, Threatening Global Energy Security

Breaking News, Climate Actions, Environment

Climate change is set to have profound effects on wind power, a crucial component of the global energy mix. With around 1 terawatt of installed wind power capacity worldwide, equivalent to the annual electricity consumption of the Netherlands, this figure is expected to double by 2030. Despite this growth, it still falls short of net-zero targets. Wind power already plays a significant role in many regions, with the UK deriving 29% of its electricity from wind in 2023 and the EU 18%. However, the future of wind power is uncertain as climate change alters wind patterns, intensifies storms, increases lightning strikes, and subjects equipment to extreme heat, potentially shortening the lifespan of turbines and increasing downtime. In the second half of 2021, Northwestern Europe experien...

Scientists Warn: Climate Change Could Bring Deadly Heat and Humidity to More Regions

Breaking News, Climate Actions, Learning & Developments

Recent weather patterns have brought extreme heat to many parts of the world, but in most inhabited regions, it typically doesn't become "too hot for people to live," especially in dry climates. In these areas, our bodies can usually cool off through the evaporation of sweat. However, in regions where hot deserts meet warm oceans, dangerous heat and humidity can combine, posing serious health risks. Regions like the Middle East, Pakistan, and India frequently experience deadly combinations of heat and humidity during summer heat waves. The humid air from nearby seas hampers sweat evaporation, preventing our bodies from cooling effectively. Hundreds of millions of people in these areas lack access to air conditioning, making the situation even more dire. Wet Bulb Temperatures and Thei...

Earth’s Atmosphere Shields Life from Deadly Supernova Explosions, New Study Reveals

Breaking News, Disasters, Space

Earth's protective atmosphere has protected life for billions of years, creating an environment for evolution to produce complex life forms like us. The ozone layer plays an important role in protecting the biosphere from deadly UV rays. Block 99% of the sun's powerful UV rays. Earth's magnetosphere also protects us. But the Sun is relatively interesting. How effectively does the ozone and magnetosphere protect us from powerful supernova explosions? Every million years - a tiny fraction of Earth's 4.5 billion years - a giant star explodes within 100 parsecs (326 light years) of Earth. We know this because our solar system exists in a space called the local bubble. A cavernous space where the density of hydrogen is lower than outside the bubble. During the previous 10-20 million ye...

Water Shortages Feared as Hindu Kush Himalaya Records Second-Lowest Snow Persistence on Record, Warns ICIMOD Report

Breaking News, Climate Actions

Snow persistence, the fraction of time snow remains on the ground, is significantly lower than normal in the Hindu Kush Himalaya this year, with serious implications for downstream communities’ water security. Leading experts from the International Centre for Integrated Mountain Development (ICIMOD), which publishes the annual Snow Update Report, warn water management officials to initiate drought management strategies and pre-emptive emergency water supply measures. The report reveals that snowmelt, a critical source of water, contributes approximately 23% of the total water flow to 12 major river basins originating in the HKH region. However, its contribution varies significantly among rivers: the Amu Darya receives 74% of its flow from snowmelt, the Helmand 77%, and the Indus 40%. ...

Nepal’s Wildfires Intensify: Over 5,000 Blazes Recorded in 2024 Amidst Climate Change and Forest Mismanagement Concerns

Breaking News, Climate Actions, Disasters

Nepal is grappling with an alarming increase in the frequency and intensity of wildfires, with nearly 5,000 incidents recorded this year alone. This makes 2024 the second-worst year for wildfires since records began in 2002, surpassed only by the devastating fire season of 2021, which saw over 6,300 outbreaks. In the past 12 months, more than 100 people have lost their lives due to wildfires, and the capital city, Kathmandu, was shrouded in hazardous wildfire smog for days on end. Climate models predict that Nepal will continue to experience more frequent drought conditions in the future, likely exacerbating the wildfire situation. However, forest scientists suggest that the increasing incidence of wildfires is not solely due to climate change. They point to changes in Nepalese communit...

Slowing of Earth’s Inner Core May Alter Length of Days, Study Reveals

Breaking News, Space

A groundbreaking study has found "clear evidence" that the Earth's inner core has slowed its rotation relative to the planet's surface since 2010, potentially affecting the length of a day by a fraction of a second. The inner core, a solid sphere of iron and nickel, is encased within the liquid outer core and stabilized by gravity. Researchers typically study the core through seismograms, which record waves generated by earthquakes. "When I first saw the seismograms showing these changes, I was shocked," said John Widale, Earth sciences professor at the University of Southern California. "But after finding dozens more observations with the same pattern, the conclusion was inescapable. The inner core has slowed down for the first time in decades," added Widale, co-author of the study ...
