The Oxford Dictionary has announced that “climate emergency” is the word of 2019. “Global heating” was a close runner up. They also explain why each of these can be considered “a word”.
Such multipart constructions, like “heart attack”, “man-of-war” or the 2017 American Dialect Society word of the year “fake news”, are commonly accepted by linguists as words.

The rate of melting in Antarctica is accelerating, according to a new study in Nature.
…it lost 2,720 ± 1,390 billion tonnes of ice between 1992 and 2017, which corresponds to an increase in mean sea level of 7.6 ± 3.9 millimetres (errors are one standard deviation). Over this period, ocean-driven melting has caused rates of ice loss from West Antarctica to increase from 53 ± 29 billion to 159 ± 26 billion tonnes per year; ice-shelf collapse has increased the rate of ice loss from the Antarctic Peninsula from 7 ± 13 billion to 33 ± 16 billion tonnes per year.
BREAKING NEWS: According to Richard Muller from UC Berkeley, global warming is caused by the increase in carbon dioxide in the atmosphere. Not changes in the Earth’s orbit, not changes in volcanic activity. Either changes in carbon dioxide or something else that happens to exactly match changes in carbon dioxide. But in all seriousness, this guy is a serious physicist who set out to challenge the findings of the IPCC using hard data, and says he ended up confirming them beyond a shadow of a doubt.
NOAA has released its Arctic Report Card for 2017. It sounds like 2017 was relatively cool, but the longer-term trend is still sharply warmer.
Taken alone, observations made in spring and summer 2017 might encourage a relaxation in the concerns over environmental conditions in the Arctic. However, when taken in context, there are many strong signals that continue to indicate that the Arctic environmental system has reached a ‘new normal’. While modulated by natural variability in regional and seasonal fluctuations, this ‘new normal’ is characterized by Arctic air temperatures that are warming at double the rate of the global temperature increase. Accordingly, there are pronounced decade-long declines in the extent and volume of the sea ice cover, the extent and duration of the winter snow cover, and the mass of the Greenland Ice Sheet and Arctic glaciers. Temperatures are increasing in the surface of the Arctic Ocean, contributing to later formation of the sea ice cover in the autumn. Temperatures are also increasing in the permafrost on the adjacent continents. Arctic paleo-reconstructions, which extend back millions of years, indicate that the magnitude and pace of the 21st century sea-ice decline and surface ocean warming is unprecedented in at least the last 1,500 years and likely much longer.
Thank you, junky weather site wunderground.com for this headline: 2014: Hottest Year in Recorded Human History. Actually this is a pretty good post with a lot of interesting graphs that you can stare at for a long, long time.
According to NOAA’s National Climatic Data Center, global surface temperatures in 2014 were 1.24°F (0.69°C) above the 20th century average, highest among all years in the 1880-2014 record, easily breaking the previous records of 2005 and 2010 by 0.07°F (0.04°C). Using independent measurement techniques but mostly the same set of surface stations, NASA also rated 2014 as the warmest year on record, as did the Japan Meteorological Agency (JMA).
This article talks briefly about the idea that “The rate of global warming since 2000 has been slower than in the 1980s and 1990s…” If you stare at the graphs long enough, you can understand how both of these things are true. From around 1980 to 2000, air temperatures got a lot hotter. From 2000 to now, they have stayed about the same, which is to say constantly very hot. So it is easy for a given year to edge a tiny bit higher than the year before and be the new hottest year ever.
