Students in Sosua create billboards to raise awareness.

Students in the Marine Ecology Project-Based Learning Group at the International School of Sosua, Dominican Republic.

Students created billboards symbolizing the major human-induced threats to our oceans – climate change, marine pollution, and overfishing.  Their artwork is to be displayed at their school to create awareness.

One in six of world’s species faces extinction due to climate change

One in six of the planet’s species will be lost forever to extinction if world leaders fail to take action on climate change, according to a new analysis.

Relatively small land masses in Australia and New Zealand mean that many species there will be unable to migrate to cope with rising temperatures, found the study, published in the journal Science on Thursday.

The study is the most comprehensive look yet at the impact of climate change on biodiversity loss, analysing 131 existing studies on the subject. The stresses on wildlife and their habitats from global warming is in addition to pressures such as deforestation, pollution and overfishing that have already seen the world lose half its animals in the past 40 years.

But even if governments do manage to hold global warming to 2C, one in 20 species (5.2%) still face extinction, the study found.

If manmade greenhouse gas emissions continue at their current record-breaking rate, leading to a temperature rise of more than 4C by the end of the century, 16% of species, or one in six, face extinction.

The study also emphasises that even for the animals and plants that avoid extinction, climate change could bring about substantial changes in their numbers and distribution.
