Unusual study suggests saving corals requires battling deforestation first

Conservationists fighting to save coastal coral reefs should think first about combatting local deforestation rather than attacking the wider peril of global warming, suggests an unusual study published on Tuesday. Sediment washed downriver by tree-depleted land can cripple near-shore corals, as it clouds the water and diminishes the light on…

Zombie climate skeptic theories survive only in newspapers and on TV

Study finds overwhelming scientific consensus that humans have caused global warming, but media still hasn’t caught up Here’s the news from 1991 – a vanishingly small number of peer-reviewed studies in science journals argue that humans aren’t the cause of global warming. Here’s the news from 2013 – since 1991,…

Scientists: Climate change will create hundreds of millions of new homeless people

It is increasingly likely that hundreds of millions of people will be displaced from their homelands in the near future as a result of global warming. That is the stark warning of economist and climate changeexpert Lord Stern following the news last week that concentrations of carbon dioxide in our atmosphere…

Plants help curb global warming by releasing particles that reflect sunlight back into space: study

It’s well known that plants can help mitigate global warming, by absorbing carbon dioxide and trapping it, via…  …

Global warming: Not reversible, but stoppable

Let’s start with two skill-testing questions: 1. If we stop greenhouse gas emissions, won’t the climate naturally go back to the way it was before? 2. Isn’t there “warming in the pipeline” that will continue to heat up the planet no matter what we do? The correct……

Explaining climate change science and rebutting global warming misinformation

Scientific skepticism is healthy. Scientists should always challenge themselves to improve their understanding. Yet this isn’t what happens with climate change denial. Skeptics vigorously criticise any evidence that supports…  …

Arctic ‘greening’ seen through global warming

Land within the Arctic circle is likely to experience explosive “greening” in the next few decades as grass, shrubs and trees thrive in soil stripped of ice and permafrost by global warming, a study said on Sunday. Wooded areas in the Arctic could increase by as much as 52 percent…

Canada’s glaciers could shrink by a fifth by 2100

A fifth of Canada’s glaciers could be gone by the end of the century, a casualty of global warming that would drive a 1.4-inch (3.5-centimeter) rise in sea levels, a study found Thursday. “Even if we only assume moderate global warming, it is still highly likely that the ice is…

Climate scientists: Carbon dioxide rose along with temperatures that ended the Ice Age

Levels of carbon dioxide rose hand-in-hand with warming at the end of the last Ice Age, according to a study Thursday that deals a blow to climate skeptics. French researchers said they had answered a riddle that has perplexed scientists. The question arises from bubbles of atmospheric air, trapped in…

Heat stress from global warming reduces labor efficiency: study

Heat stress from global warming may be having an impact on outdoor work productivity in hot regions like northern Australia, Southeast Asia and the southern United States, a study said Sunday. In recent decades, rising temperatures and higher humidity reduced labour capacity, on paper at least, by 10 percent during…
