Human carbon emissions to rise in 2019
Human carbon emissions to rise in 2019 Tropical forests continue to suffer devastation. Image: By ViniLowRaw on Unsplash Here comes another dismal science forecast, with human carbon emissions due to rise this year. Forests may be unable to keep pace as global warming increases.

Permafrost thaws as global warming sets in
Permafrost thaws as global warming sets in Stone circles caused by permafrost on the Norwegian archipelago of Svalbard. Image: By Hannes Grobe, via Wikimedia Commons Global warming is at work far below the surface, at depths seemingly insulated from the greenhouse effect. This is bad news for the permafrost. LONDON, 29 January, 2019 – Even in […]
Polar ice loss speeds up by leaps and bounds
Polar ice loss speeds up by leaps and bounds More ice is melting in Antarctica, threatening much faster sea level rise. Image: By Danielle Barneson Unsplash North and south, polar ice loss is happening faster than ever. Researchers now have a measure of the accelerating flow into the ocean.

Warming may mean sea levels 30 cms higher
Warming may mean sea levels 30 cms higher An Irish railway station, built with sea level rise in mind. Image: By Sarah777, via Wikipedia Commons Warmer oceans mean higher tides, bigger storm surges and heavier rainstorms. With ocean temperatures rising ever faster, sea levels 30 cms higher are possible by 2100. LONDON, 14 January, 2019 […]

Antarctic techno-fix cannot slow rising seas
Antarctic techno-fix cannot slow rising seas Pumping seawater into Antarctica is unlikely to halt sea-level rise. Image: Lyubomir Ivanov via Wikimedia Commons Pumping seawater onto the Antarctic landmass to form ice and stop sea levels rising stands little chance of success, scientists say. LONDON, 10 March, 2016 – Sea level rise is likely to be a problem […]
