A global climate change deal was approved today by delegates from around the world at a conference in Paris.
The agreement sets an ambitious goal of halting average global warming at no more than 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial temperatures -- and of striving for a limit of 1.5 degrees Celsius if possible.
The agreement still faces hurdles. It will go into effect only if 55 countries that account for 55% of total global greenhouse gas emissions ratify it. Ref. CNN
Method To Predict Local Climate Change Developed

Global climate models are essential for climate prediction and assessing the impacts of climate change across large areas, but a team has now developed a new method to project future climate scenarios at the local level.
Fear Itself Can Help Restore Ecosystems Study Suggests
Science Related News
Lions, wolves and other large carnivores are frightening beasts that strike fear into humans and other animals. A new study demonstrates that the fear these top predators inspire can have cascading effects down the food chain critical to maintaining healthy ecosystems, making large carnivore conservation all the more valuable given the significant 'ecosystem service' the fear of them provides.
Science can now link climate change with some extreme weather events
Extreme weather events like floods, heat waves and droughts can devastate communities and populations worldwide. Recent scientific advances have enabled researchers to confidently say that the increased intensity and frequency of some, but not all, of these extreme weather events is influenced by human-induced climate change, according to a new report.

Volcanoes tied to shifts in Earth's climate over millions of years
A new study reveals that volcanic activity associated with the plate-tectonic movement of continents may be responsible for climatic shifts from hot to cold over tens and hundreds of millions of years throughout much of Earth's history. Ref. Source 2l.
Carbon dioxide fertilization greening Earth, study finds
From a quarter to half of Earth's vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study. Ref. Source 2p.
New data on variability of Earth's reflectance over the last 16 years
The Earth's albedo is a fundamental atmospheric parameter having deep implications for temperature and climate change. Experiments have been performed to monitor it over the past two decades to reveal how it evolves. One of these has brought up to date the observations made since 2007 and gives a new systematic record of the Earth's albedo covering the period between 1998-2014. Ref. Source 8u.
