Coastal regions should note that last month saw second warmest April on record & also saw record-low Arctic, near-record-low Antarctic sea ice

“The average global temperature for April 2017 was 1.62 degrees F above the 20th-century average of 56.7 degrees, according to the analysis by scientists from NOAA’s National Centers for Environmental Information. This was the second highest for April in the 1880-2017 record, behind last year by 0.31 degrees.” [US National Oceanic and Atmospheric Administration (NOAA), May 2017]
The Northern Star, 24 May 2017:

INUNDATION THREAT: Areas in dark blue show the impact of a 0.74m seal level rise, while areas in light blue show a 2m rise.

NEW modelling has escalated the threat of sea level rises to the North Coast putting many more homes and valuable public infrastructure at risk.

Just four years after an initial report predicted a worst-case 0.74m sea level rise, rapid melting of the Antarctic and Greenland ice sheets have prompted scientists to publish a new report which predicts a 2m rise, although the chances of this worst-case scenario occurring are just 2%.

The research data provided by the US National Oceanic and Atmospheric Administration has been mapped into an interactive website published by Coastal Risk Australia, which puts the 2013 and 2017 predictions side by side.

Dark blue represents a 0.74m sea level rise and light blue represents the inundation spread with a 2m seal level rise, based
on US National Oceanic and Atmospheric Administration (NOAA) calculations

The Australian national mean temperature for April 2017 was 0.09 °C above average, according to the Australian Bureau of Meteorology.

With the continuation of warm conditions contributing to the sixth warmest January to April period on record.
