Here Are Five of The Main Reasons People Continue to Deny Climate Change – ScienceAlert

The fossil fuel industry, political lobbyists, media moguls and individuals have spent the past 30 years sowing doubt about the reality of climate change – where none exists. The latest estimate is that the world’s five largest publicly-owned oil and…

COP25 special collection: Keep climate change impacts under control by making biodiversity a focus

(American Association for the Advancement of Science) Under a 2°Celsius warming scenario, 80 to 83% of language areas in New Guinea — home to the greatest biological and linguistic diversity of any tropical island on Earth — will experience decreases in the diversity of useful plant species by 2070, according to a new study.

Forests face climate change tug of war

Increased carbon dioxide allows plants to photosynthesize more and use less water. But warmer temperatures drive plants to use more water and photosynthesize less. So, which force, CO2 fertilization or heat stress, wins this climate tug of war? It depends on whether forests and trees are able to adapt to their new environment.

Two million-year-old ice cores provide first direct observations of an ancient climate

(Princeton University) Princeton University-led researchers have extracted 2 million-year-old ice cores from Antarctica — the oldest yet recovered — that provide the first direct observations of prehistoric atmospheric conditions and temperatures. They used data from the ice cores to answer long-held questions about how our current colder, longer glacial cycle emerged.

There are variations in plankton biodiversity and activity from the equator to the poles

(CNRS) New results from the Tara Oceans expedition, led by a collaboration between the Tara Ocean Foundation and teams from the CNRS, EMBL, CEA, Sorbonne Université and Université Paris Science Lettres between 2009 and 2013 show that the diversity and functions of planktonic species in the global ocean change dramatically according to latitude.

Individual climate models may not provide the complete picture

(Penn State) Equilibrium climate sensitivity — how sensitive the Earth’s climate is to changes in atmospheric carbon dioxide — may be underestimated in individual climate models, according to a team of climate scientists.
