Simple statement: 13 of the 15 warmest years ever recorded have occurred within the first 15 years of this century. Complicated question: what is the probability that this happened purely by chance? The latest calculated answer: it could be one in 5000, or it could be as unlikely as one in 170,000, or it could be somewhere in between. Conclusion: […]

Male orcas usually live for about 50 years, but females often survive well into their 90s, making them one of the few mammalsthat live for decades after they stop reproducing. Marine scientists studied the behavior […]

Climate change, not just increasing atmospheric temperatures, has been affecting the Jet Stream. When the Jet Stream travels across from the West to the East over the Northern Hemisphere in normal conditions the weather is not greatly affected, but because of the climate change it has been slowing down and causing massive heat waves and flooding. When the jet stream […]

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters. As climate observations show that global warming leads to fewer but more intense rainfalls, a clearer understanding of how these sources are replenished is crucial for developing […]

Have you ever thought to yourself, “Can plants talk to each other?” Unsettling news for vegetarians: Plants may communicate with one another by making sounds at frequencies that humans can’t hear. British and Australian researchers have discovered that the roots of corn saplings emit a constant clicking sound. When a similar sound was played in a lab, they found that […]

In a study published in the journal Nature Climate Change, scientists from three universities show that products made in China are associated with significantly higher carbon dioxide emissions than the same products made elsewhere. “The amazing increase in Chinese manufacturing over the past 15 years has driven the world economy to new heights and supplied consumers in developed countries with […]

Despite no legal prohibition on flying over Antarctica, the continent remains largely bypassed by regular commercial airlines. Experts point to a combination of environmental challenges, regulatory hurdles, and economic factors that make the South Pole a less-than-ideal route for modern aviation. Harsh Weather and Treacherous TerrainAntarctica is notorious for its extreme cold, unpredictable weather, and formidable terrain. Sudden storms, biting […]
