Explainer: The high-emissions ‘RCP8.5’ global warming scenario

A sizeable portion of recent studies on future climate impacts have focused on a warming scenario called “RCP8.5”. This high-emissions scenario is frequently referred to as “business as usual”, suggesting that is a likely outcome if society does not make concerted efforts to cut greenhouse gas emissions. In recent years the emissions scenario used to …

Wait, melting glaciers are helping capture carbon?

This story was originally published by WIRED and is reproduced here as part of the Climate Desk collaboration. Full-tilt chaos has descended on the Arctic, a region that’s now warming twice as fast as the rest of the planet. This summer it’s been sweltering under unprecedented heat, and wildfires have so far consumed 2.4 million …

The Trump administration tried to bury a climate study on … rice?

The U.S. Department of Agriculture is supposed to use the “latest available science” to help the nation’s farmers avoid risk, according to its own mission. So it was more than a little surprising when, last year, the agency decided not to promote an alarming study (that two of its employees had contributed to) that showed …

We’ve got another ozone problem, and it’s not what you think

Most of us know ozone as that benevolent stratospheric layer that absorbs the sun’s harmful UV light and keeps us safe. In the 1980s, scientists found a “hole” in the ozone layer — really just a large section that was getting precariously thin — caused by the use of potent chemicals called CFCs. The world …

Curcumin May Help Prevent Or Combat Stomach Cancer, Study Finds

By Amanda Froelich Though few of us know it, the majority of the populace suffers from stomach problems. If low hydrochloric acid levels (which can result in poor digestion, bloating, and skin conditions) isn’t the issue, ulcers or acid buildup (typically caused by stress and poor diet) might be. Fortunately, a component found in turmeric …

The Science Behind Yoga and Stress

By Dr. M Storoni MD PhD, Uplift There are two functional parts of the brain that play a key role in stress. These serve the functions of emotion and cognitive function. So I am calling them the ’emotional’ brain (amygdala and its connections and medial forebrain structures including the medial prefrontal cortex) and the ‘logical’ …

Rising water stress could counteract ‘global greening’, study says

The increased growth rate of plants seen worldwide in response to rising CO2 levels – a phenomenon known as “global greening” – could be stalled by growing water stress, a study finds. Global warming is driving changes to water vapour levels, the research finds, which could, in turn, be affecting the rate of plant photosynthesis – the …

The climate change ‘tipping point’ has already arrived for these 70 U.S. counties

For years now now, we’ve been hearing warnings about 2 degrees Celsius of warming — the global average cautioned against as part of the 2015 Paris accord. But according to a Washington Post interactive published on Tuesday, that so-called “tipping point” has already arrived in many towns across the country. The earth is warming at …
