Melting glaciers release methane
Geologists studied gas fluxes from groundwater springs uncovered by melting Arctic glaciers. They estimated that these springs release over…
Volcanism warmed past Earth
Geologists dated a global warming event about 180 million years ago. They found it lasted between 169,000 and 417,000 years and was linked…
Microbes make different greenhouse gases during wetland drainage
Researchers found that soil microbes release less methane but more carbon dioxide and nitrous oxide in draining peatlands.
Rising soil temperatures could stop forests spreading
Researchers found higher soil surface temperatures prevented seedling survival and forest expansion in low-elevation forests.
Global warming could impact bumblebees’ senses
Researchers showed that rising temperatures make it harder for bumblebees to detect their sugary food sources.
Exoplanets with weird orbits might be more habitable
Astronomers modeled the ideal climatic and atmospheric conditions for exoplanets and found that planets with non-circular orbits had more…
How will the melting Greenland Ice Sheet affect ocean currents?
Researchers found the melting Greenland Ice Sheet is releasing tons of icebergs into the North Atlantic Ocean that could further disrupt…
What’s making Earth’s atmosphere drier?
Scientists investigated humidity patterns in tree rings across Europe to test whether recently drier air is natural or caused by global…
How do mountains affect Earth’s climate?
Scientists showed sulfuric acid formed during weathering of rocks causes mountains to consume less greenhouse gasses than they previously…
