In December 2018, The Guardian changed its wording-using ''global heating'' instead of ''global warming'' -after scientists found that Earth's temperature is set to rise from between 2.5C and 4.5C. There had been a goal to keep the rise within 2C. And on May 1, the UK parliament (议会) declared a ''climate emergency'', becoming the first parliament to do so.

It's true that ''global heating'' and ''climate emergency'' are – in terms of language – two simple phrases. But they send out plenty of messages.

If with ''global warming'' we're still inside our comfort zone of handling the situation, entering the state of ''global heating'' is like heading to a point where the delicate (微妙的) balance of nature is disturbed so much that there is no turning back. Everything will be changing: Coral will die, polar bears will lose their habitats completely, and extreme weathers like droughts and heavy storms will happen at a higher frequency. There is no denying that we're entering a ''climate emergency''.

''Decades ago when the science on the climate issue was first increasing, the impacts could be seen as an issue for future generations, '' but, as Katharine Mach, a Stanford University climate scientist, told The New York Times, now it's definitely our issue, ''a shift (变化) we all are living together''.

However, getting these messages through is far from enough. It depends on each and every one of us to find a solution – if there are any solutions left to find.

''We have no time to waste, '' said the UK's Labour leader Jeremy Corbyn, according to the BBC. Corbyn urged that ''we take rapid and dramatic action now''.

Indeed, language matters. But action matters even more.
