Earth has room to reforest an area the size of the United States, but it’s no silver bullet for climate change

Michael Irving July 4, 2019

How effective would planting new trees be to combat climate change? A new study from ETH Zurich has found that Earth has room to reforest an area the size of the US, and calculates what benefits that might bring. But of course, the story is more complicated than just planting a trillion new trees.

A new study has quantified how much land is available for reforestation, and how effective that ...

How the hole in the ozone layer is affecting climate change

Michael Irving June 24, 2019

The hole in the ozone layer may be on the mend, but its environmental impacts are ongoing. A new review study has examined the effects that the extra UV radiation is having on the environment, such as shifting climate zones, changing ocean temperatures and making some species more vulnerable.

Declassified spy satellite photos reveal accelerating ice loss at Earth's "third pole"

Michael Irving June 21, 2019

Declassified spy satellite photos have revealed that compared to the last quarter of the 20th century, Himalayan glaciers have been melting twice as fast this century. In a rare piece of good news, a separate study has shown that a Greenland glacier has gained ice for the third year in a row.

Forests that live fast and die young may help speed up climate change

Michael Irving May 15, 2019

New research led by the University of Cambridge has found that forests may not be as useful a carbon sink as we thought. The team found that a warming climate makes trees grow faster and die younger, releasing their captured carbon back into the air sooner.

Researchers examined samples taken from trees in the Spanish Pyrenees and found that faster-growing trees tend ...

Stalled waves in the jet stream blamed for last year's extreme weather events

Michael Irving April 30, 2019

The summer of 2018 was marked by extreme weather events like droughts and floods. A new study has pinned the blame on stalled giant waves in the jet stream, and unfortunately they’re expected to only get worse with the changing climate.

Climate researchers have blamed stalled giant waves in the jet stream for some of last year's ...

Glaciers have lost 9 trillion tonnes of ice since 1961, says satellite study

Michael Irving April 8, 2019

A comprehensive study has combined field observations and satellite data to track glacial ice loss. The team found that between 1961 and 2016, glaciers globally lost a total of over 9 trillion tonnes of ice, contributing significantly to sea level rise.

Can tropical tectonic activity trigger ice ages?

Michael Irving March 14, 2019

Carbon dioxide in the atmosphere is a major driver of shifts in the Earth’s climate, and in the past too little CO2 has been associated with triggering ice ages. Now a team of scientists has found a surprising new mechanism that could lead to ice ages: Tropical tectonic activity.

Tropical tectonic activity, such as that occurring in Indonesia today, may have triggered ice ages in ...

2018 continued worrying warming trend according to multiple climate reports

Michael Irving February 6, 2019

Continuing a long-term upward trend, several climate reports released today have concluded that 2018 was among the hottest years on record. In independent analyses, NASA, NOAA and WMO have all found the past year to be dotted with broken records.

This map shows the differences in average temperatures, with yellow, orange and red indicating the largest ...

Fossil fats reveal how complex life kicked off after Snowball Earth phase

Michael Irving January 31, 2019

About 700 million years ago, basically the entire planet iced over in a period often called “Snowball Earth.” Now researchers have found fossil fats that help fill in the story of how life bounced back after this global cataclysm, and how we humans might owe our very existence to them.

Fossil fats have shown how complex life arose after Earth's "snowball" phase

Giant cavity found eating away at Antarctic glacier from underneath

Michael Irving January 30, 2019

NASA’s ongoing Operation IceBridge has found a gigantic cavity underneath Thwaites Glacier in West Antarctica, which shows that the area has suffered even more drastic ice loss in recent years than previously thought – and it’s accelerating.
