Under the influence of the recent EL Nino,
2 . In recent years, extreme weather has been on the rise. From wildfires in California, US to record-breaking rainfall in northern China this summer and most recently the flood in Libya which claimed thousands of lives, Earth seems to be whipped by extreme climate and weather patterns.
Climate whiplash (气候鞭打), or weather whiplash, refers to a quick change from one extreme weather pattern to another. It is caused by global warming. A warmer atmosphere can hold more steam. As the Earth gets warmer, more water is contained in the atmosphere. Once the temperature gets colder, it often rains more heavily. This explains why a drought is often followed by extremely heavy rain.
The region hit hardest by climate whiplash is California. Over the past decade, California has experienced lasting droughts, wildfires, heavy rainfalls, and floods. It seems that the state is either on fire or in flooding with little in between. Researchers estimate that by the end of this century, the frequency of climate whiplash will jump by 25 percent in northern California as Earth continues to become warmer.
Apart from wildfires and floods, studies showed that climate whiplash also has an impact on water quality. During dry days, the fertilizer (肥料) farmers use for plants cannot be absorbed by thirsty and dying plants. Then the following heavy rain washes the remaining fertilizer into rivers, polluting the water.
How can we deal with climate whiplash? The key lies in fighting global warming. That is to say, humans have to largely reduce the use of fossil fuels (化石燃料). Climate whiplash would happen more frequently in the future, should we fail to fight global warming effectively. Therefore, it is urgent that nations around the world double down on efforts to reduce greenhouse gas emissions.

According to the World Meteorological (气候的) Organization, El Nino is a naturally occurring climate phenomenon. It starts with unusually warm surface water in the central and eastern equatorial Pacific Ocean,
The center said the combination of El Nino and global warming would increase the chances of meteorological disasters

Health Warning as UK Swelters
People across the UK have enjoyed the sunshine this week, but they have also been advised to be careful as a heat wave hits much of the country.
A heat wave is defined
However, climate change (long-term changes to weather patterns, mostly
Heat waves can be a danger to people’s health, especially for vulnerable groups such as the elderly, children and people
The Met Office, the UK’s national weather service, has issued an amber warning. Temperatures are expected
To cope with hot weather, the NHS (National Health Service) says people should try to keep out of the Sun between 11 am and 3 pm,

A.Summer hasn’t come yet. |
B.Life is hard nowadays. |
C.Our living environment is getting worse. |
9 . More than 40 percent of Antarctica’s ice shelves have reduced in the past 25 years, potentially accelerating sea level rise by allowing more landice to flow into the ocean.
Healthy ice shelves naturally retreat and grow over time. An ice shelf is continuously flowing and advancing but will also lose mass through melting or calving, which is when its front breaks off into the ocean.
In West Antarctica, the Getz Ice Shelf experienced some of the biggest ice losses, shedding 1.9 trillion tons of ice over the study period. Most ice shelves in East Antarctica however, increased in volume or stayed the same.
The current ice shelf data set is not long enough for researchers to definitively make climate change connection yet, but it would be a ” remarkable coincidence if the natural variability in ice shelves were just that much larger.
A.Then it can gain ice from the land and grow again |
B.Ice shelves are massive floating sections of ice extending from glaciers on land. |
C.The east is not as exposed to the warm water like the other side of the continent. |
D.The thinning of the ice shelves has shown up in the surrounding environment, too. |
E.Ice shelves not just the big ones, are. steadily losing mass over time with no sign of recovery |
F.One theory is that the warmer water on the western side could be slowly coming in the region. |
G.Additionally, climate models predict ice shelves will steadily shrink in a warming world as observed, eventually hitting a tipping point for ice sheet collapse. |
All scientists subscribe to the view that it is human activity
