Climate change has thawed Arctic enough for $300m gas tanker to travel at record speed through northern sea route

August 24, 2017 — A Russian tanker has travelled through the northern sea route in record speed and without an icebreaker escort for the first time, highlighting how climate change is opening up the high Arctic. Continue reading Russian tanker sails through Arctic without icebreaker for first time

Northern tundra’s autumn carbon dioxide emissions increased 70% between 1975 and 2015, researchers find, blaming warming temperatures

May 8, 2017 — Alaska’s soils are taking far longer to freeze over as winter approaches than in previous decades, resulting in a surge in carbon dioxide emissions that could portend a much faster rate of Continue reading Slow-freezing Alaska soil driving surge in carbon dioxide emissions

The cost of allowing global temperature to rise to 2°C, rather than capping warming at 1.5°C, is an area of permafrost the size of Mexico, according to new research

April 10, 2017 — The study, carried out by a team of scientists from Sweden, Norway and the UK, is the first to work out what the ambitious targets contained in the Paris Agreement mean for permafrost loss. Continue reading Warming limit of 1.5C would save huge expanses of permafrost

How much does El Niño affect global temperature

Every day, thousands of measurements are taken across the world by weather stations, ships, satellites, floating buoys and weather balloons. Scientists combine these different data sources together to take the Earth’s temperature and see how it is changing over time

January 20, 2017 — The graph below shows the average temperature of the Earth’s surface since 1951, as measured by the US National Aeronautic and Space Administration (NASA). Continue reading How much does El Niño affect global temperature

Last year was the warmest year in recorded history, scientists confirmed today. With global temperatures topping 1°C above preindustrial times, the world has now experienced three consecutive record-warm years for the first time since records began

January 19, 2017 — The long-term warming trend from greenhouse gas emissions received an extra boost from the tail-end of a strong El Niño but 2016 would have been a record even without it, say scientists. Continue reading World’s major climate agencies confirm 2016 as hottest year on record

Obama warns of ‘climate refugees’ due to rapid Arctic warming

US Interior Secretary Sally Jewell has painted a stark picture of communities displaced by rising Arctic temperatures that are ‘washing away’ towns

April 31, 2016 — The Obama administration has warned the US will need to deal with a wave of “climate refugees” as the Arctic continues to warm, joining with the Canadian government to express alarm over how climate change is affecting indigenous communities.
