Global Tipping Points Report Warns of Irreversible Threats from Climate Change

The Global Tipping Points Report, compiled by an international team of 200 scientists and coordinated by the University of Exeter, reveals that the world is at risk of triggering at least five tipping points with potentially devastating consequences. Tipping points are critical thresholds beyond which changes in the climate system become self-perpetuating and lead to irreversible impacts. The report, set to be published during the UN Climate Conference (COP28) in Dubai, identifies the Greenland and West Antarctic Ice Sheets, warm-water coral reefs, North Atlantic subpolar gyre circulation, and permafrost regions as already at risk. The report emphasizes the inadequacy of current global governance to address the scale of the challenge and calls for coordinated action to trigger positive tip...

Australia’s Submerged Ancient Landscapes Revealed: Northwest Shelf’s Hidden History

Breaking News, Climate Actions, Learning & Developments

Recent research published in Quaternary Science Reviews unveils the hidden history of Australia’s Northwest Shelf, which was once an expansive, habitable landscape connecting the Kimberley and western Arnhem Land. This submerged continental shelf, stretching nearly 390,000 square kilometers, formed a unique cultural zone during a significant part of Australia’s human history, around 18,000 years ago. As the last ice age concluded, rising sea levels submerged this vast area, creating a complex landscape that remained undiscovered until now. The study used high-resolution maps and projections of past sea levels to reveal an archipelago, lakes, rivers, and a large inland sea that existed on the Northwest Shelf. This region, previously thought to be environmentally unproductive, turns ou...

NASA Warns of Impending Flood Risks: Strong El Niño Could Trigger Repeated Inundation Along Western Coasts

Breaking News, Climate Actions

A NASA analysis has sounded the alarm about the potential threat of increased flooding in cities along the western coasts of the Americas this winter due to a powerful El Niño. The warming of surface temperatures in the Central to East Pacific Ocean could lead to a series of significant floods, with up to five “10-year flood events” expected to impact cities like Seattle and San Diego. This article explores the implications of the NASA analysis, highlighting the risks posed by a potent El Niño and the broader concerns related to climate change and rising sea levels. El Niño’s Influence & Flood Risk Assessment El Niño, a natural phenomenon occurring every two to seven years, involves a shift in sea surface temperatures that alters equatorial trade winds. This change weakens or reverse...
