Extent of Arctic sea ice in September 2016 versus the 1981-2010 average minimum extent (gold line). Credit: NASA. Melting ice in the Arctic might seem a world away from California’s farms and aquifers. But droughts in the state could get worse as the Arctic melts.  Summers in the Arctic Ocean are expected to be ice-free within a few decades. When that happens, the precipitation California receives could decrease as much as 15 percent.

If the North Pole loses its summertime ice, precipitation in the state could drop by up to 15 percent.

This Is What Earth Will Look Like If All The Ice Melts

National Geographic shows how most coastal cities will be decimated and the population exodus will put a strain on midland resources. On the upside, Antarctica will make an great seaside resort.

CAMS produces five-day forecasts. Currently, thinning (blue) is greatest in the region towards S. America The ozone hole over Antarctica this year could be one of the smallest seen in three decades, say scientists. Observations of the gas's depletion high in the atmosphere demonstrate that it hasn't opened up in 2019 in the way it normally does. The EU's Copernicus Atmosphere Monitoring Service (CAMS) says it's currently well under half the area usually seen in mid-September.

The deep thinning in Earth's protective atmospheric layer is not as extensive as it normally is.

Satellites spy Antarctic 'upside-down ice canyon' - BBC News. In places, this has cut an inverted canyon through more than half the thickness of the shelf structure.  If the melting continued unabated, it would break Dotson in 40-50 years, not the 200 years currently projected.

An Antarctic ice shelf is shown to have a deep gorge cut in its underside by warm ocean water.

Long-term global warming and a strong El Niño effect combined to set a new record for the planet.  A report compiled by a US government agency has confirmed that 2016 was the warmest year on record and the third year in a row of record global warmth. The heat was the result of long-term global warming and a strong El Niño weather phenomenon, the report said. Global surface and sea temperatures, sea levels and greenhouse gases levels were all at record highs, it added.

Climate change dials down Atlantic Ocean heating system.  A significant shift in the system of ocean currents that helps keep parts of Europe warm could send temperatures in the UK lower, scientists have found. They say the Atlantic Ocean circulation system is weaker now than it has been for more than 1,000 years - and has changed significantly in the past 150.

Ice melt 'weakens ocean heating system'

An Atlantic Ocean circulation system that warms Europe's climate is weaker today than it has been in 1,000 years, say scientists.

Ozone layer recovery could be delayed by 30 years - BBC News. Rising global emissions of some chlorine-containing chemicals could slow the progress made in healing the ozone layer. A study found the substances, widely used for paint stripping and in the manufacture of PVC, are increasing much faster than previously thought. Mainly produced in China, these compounds are not currently regulated.

Ozone hole mystery: China insulating chemical said to be source of rise. Cut-price Chinese home insulation is being blamed for a massive rise in emissions of a gas, highly damaging to the Earth's protective ozone layer.  The Environmental Investigations Agency (EIA) found widespread use of CFC-11 in China, even though the chemical was fully banned back in 2010.  Scientists have been extremely puzzled by the mysterious rise in emissions.

CEFAS scientists create first UK map of shipping 'noise' The first UK-wide map of underwater noise made by ships has been created, marine scientists have said. Researchers from the Centre for Environment, Fisheries and Aquaculture Science (Cefas) in Suffolk used data captured from microphones placed on the seabed to identify "hotspots". Dr Nathan Merchant, from Cefas, said he was "concerned" about potential effects on how marine mammals "communicate".

Scientists want to evaluate the potential effects of sound "hotspots" on marine life.

Antarctic glacier’s rough belly exposed. The melting Antarctic ice stream that is currently adding most to sea-level rise may be more resilient to change than previously recognised. New radar images reveal the mighty Pine Island Glacier (PIG) to be sitting on a rugged rock bed populated by big hills, tall cliffs and deep scour marks.  Such features are likely to slow the ice body’s retreat as the climate warms, researchers say.

Nasa carbon space observatory 'watches Earth breathe'. A Nasa satellite has provided remarkable new insights on how CO2 is moved through the Earth's atmosphere.  The Orbiting Carbon Observatory (OCO) tracked the behaviour of the gas in 2015/2016 - a period when the planet experienced a major El Niño event.  This climate phenomenon boosts the amount of CO2 in the air.

Slowing Gulf Stream current to boost warming for 20 years. The prospect of the Gulf Stream slowing down and even stopping altogether has worried many experts in recent years.  Some believed that this would cause a rapid cooling around the world with resulting global chaos. But a new study finds the Gulf Stream go-slow will have a significant impact on planetary temperatures, but not in a chilled out way.

Slower ocean current to boost warming

The Atlantic system that warms the UK is slowing down but this may cause even more heating.

There is something very distinct about the air over India and the surrounding countries in South Asia.  It is the presence of formaldehyde - a colourless gas that is naturally released by vegetation but also from a number of polluting activities.  The elevated concentrations have been observed by Europe's new Sentinel-5P satellite, which was launched last October to track air quality worldwide.  It is information that will inform policies to clean up the atmosphere.

Climate change: Greenland ice melt 'is accelerating'  Greenland is losing ice 7 times faster than it was in the 1990s.  The assessment comes from an international team of polar scientists who've reviewed all the satellite observations over a 26-year period.  Greenland's contribution to sea-level rise is currently tracking what had been regarded as a pessimistic projection of the future. It means an additional 7cm of ocean rise could now be expected by the end of the century from Greenland…
