Excessive hospital occupancy levels result in avoidable mortality

Excessive hospital occupancy levels result in avoidable mortality | Sustain Our Earth | Scoop.it
Once a hospital reaches a certain occupancy level, the quality of care it provides deteriorates, increasing the risk of mortality of critically ill patients. What is worrying is that this safety 'tipping point' is reached at occupancy levels that are below 100%. The findings are reported by a team of ...

Explainer: How do cyclists reach super fast speeds? | Sustain Our Earth | Scoop.it
Even though spoked wheels and pneumatic tyres were invented in the 1880s, bicycle design hasn't really changed a great deal in the time since – at least, at face value. However, look closer and around a hundred years of research or development has taken the humble bicycle from boneshaker to a speed ...

Methane-producing microbes may be responsible for the largest mass extinction in Earth's history

Methane-producing microbes may be responsible for the largest mass extinction in Earth's history | Sustain Our Earth | Scoop.it
Evidence left at the crime scene is abundant and global: Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out—by far the largest of this planet's five known mass extinctions. But pinpointing the culprit has been difficult, ...

Research indicates 60-year decline in groundwater levels across US

Research indicates 60-year decline in groundwater levels across US | Sustain Our Earth | Scoop.it

The Columbia Water Center, part of the Earth Institute at Columbia University, announced today the release of a new white paper, 'Assessment of Groundwater Level Trends across the United States,' that analyzes long-term groundwater trends across the United States. The study found that historic groundwater levels have declined across much of the country over the last 60 years, suggesting that current groundwater management is broadly unsustainable. The paper was released as part of the Water Center's new "America's Water Initiative."

Climate change: regional impact

Climate change: regional impact | Sustain Our Earth | Scoop.it

This is how climate change may affect the world's regions this century, as forecast in a major report published by UN scientists Monday.

 

The report is part of the fifth overview on global warming by the Intergovernmental Panel on Climate Change (IPCC) since 1988.

 

The document identifies each region's key challenges; options for addressing them; and level of risk from warming of either 2 C (3.6 F) or 4 C (7.2 F) by 2100 compared to pre-industrial levels. This risk is calculated on the basis of present policies for adapting to climate change.
