- 1Permafrost and wetland emissions could amplify climate change by 30%▼Permafrost, wetland, wildfire and freshwater emissions could amplify climate change by up to 30%, study finds
A new study finds that emissions from permafrost thaw, wetlands, wildfires and freshwater systems could amplify climate change by up to 30%, over and above human-caused emissions. These natural feedback loops release additional carbon dioxide and methane as the planet warms, meaning current climate models may underestimate future warming. Researchers warn this strengthens the case for faster emissions cuts.
- 2Blue pigment catalyst converts CO₂ directly into methane▼New potential for mitigating climate change: blue pigment catalyst turns CO₂ directly into methane i
Researchers report that a blue pigment-based catalyst can convert carbon dioxide directly into methane, a finding presented as opening new possibilities for climate change mitigation. If scalable, the process could turn a major greenhouse gas into a usable fuel source, though questions remain about energy costs, efficiency and whether such conversion genuinely reduces overall emissions.
- 3SpaceX's Merlin and Raptor engines compared▼Merlin Vs. Raptor: How Do These SpaceX Rocket Engines Compare?
A comparison of SpaceX's two main rocket engines, the Merlin and the Raptor, is drawing attention. Merlin, which burns rocket-grade kerosene, powers the Falcon 9 and Falcon Heavy, while the methane-fuelled Raptor drives the Starship program. The discussion focuses on how the engines differ in fuel, design, thrust and reusability, and what those trade-offs mean for SpaceX's current and future missions.
