Polar Bear Populations Decline in Greenland Over 20,000 Years Due to Climate Change

A comprehensive international study, including researchers from the University of Copenhagen, reveals a concerning decline in polar bear numbers in Greenland over the last 20,000 years. The research, combining genetic analysis, food habits, habitat study, and historical climate data, points to rising sea temperatures as the key driver behind this decline. The study, published in Science Advances, emphasizes the impact of global warming, leading to increased sea temperatures and reduced sea ice, consequently affecting the polar bear‘s primary food source – seals. Michael Westbury, lead author and assistant professor at the University of Copenhagen, highlights the non-linear relationship, where even small environmental changes significantly impact polar bear populations. The research ind...

Ice Cores data from Nevado Huascaran Provide Insights into Amazon Basin’s Climate History

Breaking News, Climate Actions

Scientists from Ohio State University (OSU) have studied ice cores from Nevado Huascaran, the world’s highest tropical mountain located in the Peruvian Andes, to gain unprecedented insights into the climate history of the Amazon Basin over the past six decades. Unlike polar regions, samples from tropical areas like Nevado Huascaran can provide valuable information about phenomena such as El Niño and the movement of monsoon winds. The research involved collecting ice core samples from the summit and the mountain col, the lowest point between two ridges. Key Points: •Nevado Huascaran, standing at nearly 7,000 meters above sea level, is the world’s highest tropical mountain. •Ice core samples were collected from the summit and the mountain col to analyze the impact of climate change ...

NASA’s Fermi Gamma-Ray Space Telescope Captures 14 Years of the Universe’s Gamma Radiation in Stunning Timelapse

Breaking News, Space, Tech

A timelapse compiled from data collected by NASA’s Fermi Gamma-Ray Space Telescope between August 2008 and August 2022 reveals a captivating view of the Universe’s gamma radiation. Fermi, launched in 2008, has been instrumental in studying gamma radiation sources, including those emanating from supernova remnants, pulsar stars, quasar and blazar galaxies, and other energetic celestial phenomena. Gamma radiation, being the most energetic light in the cosmos, is typically blocked by Earth’s atmosphere, necessitating the deployment of telescopes like Fermi in space to capture this elusive light. The recently released timelapse showcases the diverse sources of gamma radiation observed by Fermi over the course of 14 years. Judy Racusin, an astronomer at NASA’s Goddard Space Flight Center,...

Dimming the Sun: A Radical Solution to Climate Change or a Cosmic Conundrum?

Breaking News, Disasters, Idea & Innovations, Space

In a bid to combat the relentless march of climate change, scientists are proposing an unconventional approach: dimming the Sun. With global temperatures surpassing critical thresholds, a team of researchers suggests mimicking the cooling effect of major volcanic eruptions by creating an artificial haze in the upper atmosphere. While this may sound like the stuff of science fiction, experts argue it could be a feasible solution to curb the warming trend. The Earth’s warming, primarily driven by greenhouse gases like CO₂, could be counteracted by releasing reflective particles into the upper atmosphere. The goal is to dim the Sun by approximately 1%, which, according to research, could cool the planet by 1°C. This approach has historical precedent, as natural phenomena like volcanic erup...

Climate Change Poses Growing Risk of Glacial Lake Outburst Floods in the Third Pole Region

Breaking News, Environment, Thoughts & Talks

December 17, 2023, A new study published in the journal Nature Communications has raised climate change alarms about the increasing threat of Glacial Lake Outburst Floods (GLOFs) in the Third Pole region, encompassing the Tibetan Plateau, the Himalayas, Hindu Kush, and Tianshan Mountain ranges. Researchers from the Chinese Academy of Sciences have highlighted the vulnerability of this ecologically crucial area to the impacts of climate change. The research indicates that the expansion of glacial lakes and the emergence of new ones in the Third Pole region are likely to result in a higher frequency of GLOFs in the coming years. This calls for the development of improved analytical methods and datasets to anticipate and mitigate potential disasters associated with these events. The Thi...
