This is the Perito Moreno glacier in Patagonia One of the most breathtaking world wonders I have ever seen I felt the majesticness in every inch of my body, shivers down my spine It's part of the third largest sweet water reservoir in the world, after Antarctica and Greenland. Between 2018 and 2022, the glacier was thinning at a rate of 4 metres a year. But in the past two years, that has doubled to 8 metres annually. Exponentially, this beauty is falling prey to man-made global warming The glacier resisted global warming for more than a century but has now lost almost two square kilometres of ice in seven years. Scientists now call the trend potentially irreversible. The glacier can no longer match the heat. The ice that once anchored itself to the lakebed has become buoyant, accelerating its retreat and amplifying its own collapse. Recent summers in Patagonia reached record temperatures. Calving events are now louder, larger, and more frequent. This is not an isolated story. The Upsala, Viedma, and now Perito Moreno glacier all follow the same trajectory. It is a visible reminder that the world is losing its frozen reservoirs at a pace faster than predicted. What we choose to do with this knowledge will define the next century. Glaciers respond slowly, but societies do not have that luxury. The retreat is a warning and an invitation at the same time. An invitation to restore landscapes, regenerate ecosystems, and cool the planet from the ground up. Standing face to face with this beauty showed me that climate crisis is not abstract when a wall of ice as big as a 20-story apartment building begins to move and crashes down. 🌍 Regeneration is no longer optional 🌱 Every restored hectare of land counts. Every tree planted helps to cool down the planet. 👉🏼 After two weeks of hard work on the Argentinian island we're regenerating, we took a short break to discover the country before heading back to Europe #regenerative #landscapedesign #landscapearchitecture #agroecology #regenerativefarming #agroforestry #farming

Understanding Thermodynamic Processes in Climate Change Thermodynamics is essential for grasping climate change because it explains how energy moves and transforms in Earth’s system. This brief overview highlights the key concepts and their climate relevance. The Core Laws First Law - Energy cannot be created or destroyed, only converted. Second Law - Every energy transfer increases entropy, pushing systems toward greater disorder. These principles set the stage for how the planet balances incoming and outgoing energy. Energy Balance Solar Input - Sunlight is absorbed by the atmosphere, oceans, and land, driving weather and life. Thermal Emission - Earth radiates infrared energy back to space; greenhouse gases trap part of this radiation, producing the greenhouse effect. Small shifts in either side can trigger large climate responses. Greenhouse Effect & Feedbacks Greenhouse gases intercept outgoing infrared radiation, raising surface temperatures. Positive feedbacks amplify warming: Albedo Loss - Melting ice lowers reflectivity, absorbing more solar energy. Water Vapor Increase - Warm air holds more water vapor, a strong greenhouse gas, further boosting heat. These loops show how fossil‑fuel combustion initiates both immediate and long‑term climate impacts. Entropy’s Role The increase in entropy mirrors the inefficiency of human energy use: Fossil‑Fuel Combustion converts concentrated chemical energy into dispersed heat and CO₂, raising the system’s disorder. This added entropy manifests as altered atmospheric composition and disrupted climate patterns. Toward Sustainable Energy Understanding thermodynamics guides greener choices: Energy Efficiency - Reducing waste cuts greenhouse gas emissions. Renewables - Solar, wind, and other low‑entropy sources replace high entropy fossil fuels. Policy & Systemic Change - Coordinated actions that optimise energy flows support both environmental health and societal needs. Thermodynamic principles illuminate how Earth absorbs, transforms, and emits energy, and why entropy rises as we burn fossil fuels. Recognising these processes clarifies the climate challenges we face and underscores the necessity of efficient, renewable energy systems for a viable future. #Thermodynamics #Entropy #EnergyBalance #ClimateScience #GreenhouseEffect #SustainableEnergy #RenewableEnergy #EnergyEfficiency #CarbonFootprint #ZeroCarbon #ClimateAction #ClimateChange #EnergyEfficiency #RenewableEnergy #ClimateAction #ScienceCommunication | 88 comments on LinkedIn

How the Columbian Exchange Transformed the World 🤯 The Columbian Exchange began after Columbus’s 1492 voyage and sparked one of the biggest transformations in human history. For the first time, plants, animals, and diseases moved between the Americas and the rest of the world, reshaping societies, economies, and ecosystems. American crops like potatoes and maize spread rapidly across Europe, Africa, and Asia. Potatoes helped drive Europe’s population growth and later fueled industrial expansion, while maize became a drought-resistant staple that supported new trade networks and strong kingdoms in Africa. The arrival of horses in the Americas changed Indigenous life forever, especially among Plains tribes who used them for travel, hunting, and warfare. But this exchange also brought tragedy. Diseases such as smallpox and measles devastated Native American populations, while syphilis likely spread from the Americas to Europe. At the same time, valuable medicines like quinine—used to treat malaria—enabled Europeans to survive in tropical regions. In the end, the Columbian Exchange didn’t just alter global economies; it reshaped daily life, diets, and cultures worldwide. Even everyday favorites like chocolate owe their global popularity to this era. by Geo All Day

Tripling nuclear power is not a dream. It is a plan. And it is already in motion. Right now, 31 countries have set a bold target: triple global nuclear capacity by 2050. This is not only talk. It is a real, measurable goal, backed by national plans and hard numbers. Today, there are about 440 nuclear reactors operational worldwide. Together, they generate almost 400 gigawatts of electricity. That is enough to power hundreds of millions of homes. And the number is growing. At least 70 more reactors are being built right now, adding another 77 gigawatts. But the real story is what comes next. Governments have set targets for 2050 that add up to 1,363 gigawatts of nuclear power. That is more than triple today’s capacity. It is even higher than the 1,200 gigawatt goal set at COP28 and COP29. This is not only about numbers. It is about action. China and the USA are leading the way. Their national goals alone make up more than half of the world’s future nuclear power. Add France, India, and Russia, and these five countries will reach almost 1,000 gigawatts by 2050. The rest of the world is moving too, but these countries are the engine. Getting there will not be easy. It will take: 1. Leadership and strategic action 2. Streamlined regulatory frameworks 3. Significant investment and accessible financing across the entire nuclear value chain 4. Accelerated deployment 5. A larger, highly skilled workforce 6. Robust, resilient, and diversified supply chain 7. Strengthening the nuclear fuel cycle - from mining to fuel fabrication This is an ambitious undertaking - but it is absolutely achievable. Tripling global nuclear capacity is within reach. The momentum is real, and the imperative is clear. The world needs clean, reliable, 24/7 energy. Nuclear is ready to deliver it - safely, affordably, and at scale This is our chance to build a safer, cleaner, and more secure energy future. The path is clear. The time is now. ♻️ Repost if you like the content ➕ Follow me, Ruan Steyn, for more insights Source of graph: World Outlook Report 2050, World Nuclear Association - Global nuclear capacity (GWe) up to 2050
