Tree rings reveal El Niño linked to climate change

Tree rings reveal El Niño tied to recent global warming (via The Christian Science Monitor) Every seven years – or sometimes every two years, or maybe four years – El Niño turns a bucket of rainfall over eastern South America, sending floodwaters cascading over coastal Ecuador and typhoons spiraling into…

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,…

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…  …

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…

Human-caused and natural climate change are different, study shows

Are human-caused and natural global warming different? Study says yes. Human-triggered climate warming appears to leave a unique fingerprint on global rainfall rates compared with natural warming, according to a new study. While rainfall rates increase whether the long-term warming trend is natural or not, the rate of increase appears…

Climate scientists predict future with lower average rainfall

Climate scientists said Wednesday they found evidence to back predictions for a future with lower average rainfall, even though Earth’s past warming episodes had led to more precipitation, not less. Writing in the journal Nature, researchers said they had found proof that global warming caused by Man’s greenhouse-gas emissions has…
