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.

The 19th-century American writer and naturalist Henry David Thoreau knew the 1.(important) of nature. Thoreau filled his books with observations about human life and 2.(it) basic need for nature.
On average, Americans spend about 10 hours a day in front of a computer or other electronic device 3. less than 30 minutes a day outdoors. That is a claim 4.(make) by David Strayer, a professor of psychology at the University of Utah. In his 2017 TEDTalk, Strayer 5.(explain) that all this time spent with technology is making our brains tired.
Using an electronic device-answering emails, listening to the news, looking at Facebook -6.(put) a lot of pressure on the prefrontal cortex, the front of the brain. This area, Strayer explains, is important for critical 7.(think), problem-solving and decision-making. So, it is important to give the brain 8. rest. And being in nature, Strayer claims, helps refresh a brain that is tired from too much technology. Friends and family take time off and escape to nature for several days. Camping may be just 9. a tech-tired brain needs. Strayer's research team found that spending three days in nature without any technology is enough time for the brain to 10.(full) relax and reset itself.
