Climate change really does change everything, including language. In October, Oxford English Dictionary (OED) released     1     update on its language on climate change and environmental sustainability.

Some new words     2     (include) in the dictionary so far. The OED doesn’t include chemical formulas,     3     it has made an important exception for CO2 because it has become, in its words, deeply-rooted in our everyday language.

“Global heating” is also a new entry. Although people got used to using global warming, OED said that global heating is being used     4     (often). That’s because while global warming suggests a kind of comfort, global heating conveys “the seriousness of climate change     5     (cause) by human activity and the urgent need to address it”.

Apart from     6     (add) these new words, some old words about climate have been given new meanings. The phrase “climate refugee” is an example. In the 19^th century, when people spoke of climate refugees, they would be describing those     7     had moved to a place where the climate is healthier.

But now, as climate changes and weather events appear     8     (frequent), the phrase refers to the people who are forced to move in response to extreme weather or rising sea levels.

Trish Stewart, OED science     9     (edit), said the update reflects the very real sense of urgency of climate change now.

What happens next depends     10     so many factors but, one thing we can be sure of is that our language will continue to evolve and to tell the story.
