Climate-Driven Local Extinction Threatens Earth’s Oldest Trees

Janina Lazo-Cruz — Thu, 14 Sep 2017 18:24:46 +0000

Bristlecone pine trees, the Earth’s oldest trees, can live beyond 5,000 years, while limber pine trees can live not more than 2,000 years. The growth behavior of these two ancient Great Basin species in response to climate change was studied by researchers from the University of California, Davis. The team found out that for the […]

Fifty-five years ago, it was estimated that more than 2,000 Northern White Rhinoceros roamed the wild. About 15 years after that estimate, Sudan the rhinoceros was born, making him about 40 years old today. By 1984, he was one of barely over a dozen. Today, he is one of only five, and he also happens […]

The Earth is experiencing the largest number of wildlife extinctions since the dinosaurs vanished 65 million years ago. At a conference in Turkey on December 9-14, a 115 nation group is working to find ancient farming solutions to protect the diversity of wildlife. Zakri Abdul Hamid, the founding chair of the Intergovernmental Platform on Biodiversity […]

Climate Change Killing Moose at Alarming Rate

Leigh Hutchens — Wed, 16 Oct 2013 04:47:14 +0000

Climate change is playing a huge role in the gradual population decline and anticipated extinction of the moose. Minnesota had two different moose populations twenty years ago, and they were geographically separate. Since the 1990s, one of the populations has declined from 4000 to 100. The second population, located in northeastern Minnesota, has been dropping […]

Rising CO2 Levels May Lead to Mass Extinction of Species

Leigh Hutchens — Sat, 23 Mar 2013 03:53:00 +0000

Based upon the levels of CO2 in the atmosphere, which could continue to be released, the Earth may be heading toward conditions like those of the Paleocene-Eocene event. If this is the case, species might not be able to adapt to the extreme rate of current rise in greenhouse gases and temperatures. The incredible rate […]

Myanmar Elephants Threatened by Global Warming

Leigh Hutchens — Tue, 29 Jan 2013 08:31:54 +0000

By utilizing historical records, scientists have demonstrated that climate change may have a very devastating effect on Myanmar’s already endangered elephants. In fact, elephants are far less resilient than popularly thought and even the slightest temperature change may wipe them out. University of Sheffield scientist, Hannah Mumby, the study lead, determined that Myanmar’s elephants thrive […]
