Climate-Driven Wildfires Could Reshape Global Emissions Accounting: UN Expert

Climate-Driven Wildfires Could Reshape Global Emissions Accounting: UN Expert

Breaking News, Climate Actions, Environment, Opinions
The growing impact of climate-driven wildfires is forcing a rethink in how greenhouse gas inventories calculate emissions, says Minal Pathak, an associate professor at Ahmedabad University and co-author of the United Nations Emissions Gap Report. For the first time, the 2024 report has included wildfire emissions, highlighting the complexities of accounting for these fires in global climate data. Pathak explains that wildfires are categorized as either natural or anthropogenic, with the latter resulting from activities like agricultural burning. While CO₂ from fires is often considered carbon neutral since forests can regrow and reabsorb emissions climate change is altering this balance, making it harder to predict how forests recover and store carbon.

Green Banks Coalition Collapses as Major US Lenders Exit Net Zero Alliance

Green Banks Coalition Collapses as Major US Lenders Exit Net Zero Alliance

Breaking News, Climate Actions, Fact Check
The Net Zero Banking Alliance (NZBA), a key UN-backed coalition of financial institutions committed to climate-friendly investments, has suffered a major setback with the withdrawal of six of the largest American banks. With JP Morgan becoming the latest to exit, only three smaller US banks remain in the alliance. This mass departure underscores the growing tension between climate goals and political resistance in the US financial sector. NZBA: A Climate Commitment Now in Question The NZBA, launched ahead of COP26 in 2021, is a global network of banks pledged to align their financing with net-zero emissions targets by 2050. With 136 members across 44 countries managing assets worth $57 trillion, the alliance was meant to be a major driver of climate-conscious banking. However, its ef...
UN Report Record Greenhouse Gas Levels in 2023 Signal Dire Climate Warning

UN Report Record Greenhouse Gas Levels in 2023 Signal Dire Climate Warning

Breaking News, Climate Actions, Environment
Greenhouse gas concentrations soared to record levels in 2023, according to the United Nations, underscoring the urgency of climate action ahead of COP29 in Baku. The UN's World Meteorological Organization (WMO) revealed unprecedented increases in carbon dioxide (CO2), methane, and nitrous oxide levels, solidifying future temperature increases for decades. The WMO's Greenhouse Gas Bulletin highlighted that CO2 levels hit 420 parts per million, an 11.4% increase over 2004 levels and a staggering 51% above pre-industrial levels. This marks the twelfth consecutive year with a rise over two parts per million, propelled by substantial fossil fuel emissions over recent decades. Methane and nitrous oxide levels also surged to new highs, exacerbating the climate crisis. “Another year, anothe...
Antarctica’s Post-Glacial Uplift: A Double-Edged Sword for Future Sea Level Rise

Antarctica’s Post-Glacial Uplift: A Double-Edged Sword for Future Sea Level Rise

Breaking News, Climate Actions, Disasters
Antarctica, long regarded as a frozen behemoth, is shedding its icy weight, leading to a phenomenon known as post-glacial uplift. This process, where the land rises as the ice melts, is now recognized as a key factor that could dramatically alter projections of future global sea level rise. As the Antarctic ice sheet melts, the weight pressing down on the continent reduces, allowing the land to rise—similar to a sponge expanding after being compressed. This process, called post-glacial uplift, is happening much faster than previously thought. Recent research suggests that this land rebound could either mitigate or exacerbate Antarctica’s contribution to global sea level rise, depending on future fossil fuel emissions. Impact on Global Sea Levels Glaciologists Natalya Gomez from Mc...
Tree Ring Data Reveals 2023 as Hottest Northern Hemisphere Summer in 2,000 Years

Tree Ring Data Reveals 2023 as Hottest Northern Hemisphere Summer in 2,000 Years

Breaking News, Climate Actions, Idea & Innovations
Analysis of tree ring data indicates that the Northern Hemisphere experienced its hottest summer in 2,000 years in 2023, surpassing temperatures during the height of the Roman Empire. The findings highlight the urgency of reducing greenhouse gas emissions to mitigate the impact of climate change. A recent analysis of tree ring data has revealed that the Northern Hemisphere experienced its hottest summer in 2,000 years in 2023, surpassing temperatures recorded during the height of the Roman Empire. The study, conducted by environmental scientist Ulf Büntgen and his colleagues from the University of Cambridge and Johannes Gutenberg University in Germany, underscores the dramatic impact of recent global warming. The researchers compiled early temperature records using indirect measures ...
Scientists Develop Novel “Cage of Cages” Material for Greenhouse Gas Capture

Scientists Develop Novel “Cage of Cages” Material for Greenhouse Gas Capture

Breaking News, Disasters, Learning & Developments
In a significant breakthrough, scientists have engineered a groundbreaking porous material, described as a "cage of cages," designed to trap carbon dioxide (CO2) and other potent greenhouse gases, potentially offering a promising solution to combat climate change. Synthesized through a meticulous two-step process by researchers in the UK and China, this innovative material boasts a unique molecular structure composed of triangular prism building blocks assembled into larger, symmetrical tetrahedral cages. This molecular architecture, a first of its kind, exhibits exceptional potential for capturing and storing greenhouse gases effectively. According to Marc Little, a senior author of the study and a materials scientist at Heriot-Watt University, Edinburgh, this discovery holds tremen...
