To slow climate change the world will either have to put the brakes on economic growth or change the way the world’s economies work, scientists say. A study by University of Michigan researchers assessed the effects of several factors on year-to-year changes in atmospheric concentrations of carbon dioxide. Researchers looked at two natural phenomena believed…
For decades, a small group of scientific dissenters has been trying to shoot holes in the prevailing science of climate change, offering one reason after another why the outlook simply must be wrong. Over time, nearly every one of their arguments has been knocked down by accumulating evidence, and polls say 97% of working climate…
Despite years of intensive research about the extinction of non-avian dinosaurs about 65.5 million years ago, a fundamental question remains: were dinosaurs already undergoing a long-term decline before an asteroid hit at the end of the Cretaceous? A study led by scientists at the American Museum of Natural History gives a multifaceted answer. The findings,…
New research suggests that global warming is causing the cycle of evaporation and rainfall over the oceans to intensify more than scientists had expected, an ominous finding that may indicate a higher potential for extreme weather in coming decades. By measuring changes in salinity on the ocean’s surface, the researchers inferred that the water cycle…
Large wind farms slightly increase temperatures near the ground as the turbines’ rotor blades pull down warm air, according to researchers who analyzed nine years of satellite readings around four of the world’s biggest wind farms. The study showed for the first time that wind farms of a certain scale, while producing clean, renewable energy,…
Climate researchers pay too little attention to social sciences, the executive director of the Bolivian Mountain Institute told delegates at the International Conference of Mountain Countries on Climate Change in Nepal. “More interaction between the natural and social sciences is necessary,” said Dirk Hoffmann, adding that the lack of effective dialogue between science and social…
Scientists have detected a clear change in salinity of the world’s oceans and have found that the cycle that drives rainfall and evaporation has intensified more than thought because of global warming. The finding published in the journal Science, helps refine estimates of how different parts of the globe will be affected by increased rainfall…
Earth’s glaciers are seriously out of balance with the global climate and are already on their way to losing almost 40% of their volume. That is the assessment of scientists after studying a representative group of 144 small and large glaciers around the world. Their figures assume no further warming of the climate. However, if…
Antarctica’s massive ice shelves are shrinking because they are being eaten away from below by warm water, a new study finds. That suggests that future sea levels could rise faster than many scientists have been predicting. The western chunk of Antarctica is losing 23 feet of its floating ice sheet each year. Until now, scientists…
When it comes to adapting to climate change, diversity is the mammal’s best defense. That is one of the conclusions of the first study of how mammals in North America adapted to climate change in “deep time” – a period of 56 million years beginning with the Eocene and ending 12,000 years ago with the…
