A few weeks ago, scientists at Ukraine's Vernadsky Research Base in Antarctica found their usually white surrounds were covered in a shocking blood-red. For such a mess, the culprits behind this horrible scene are tiny.
"Our scientists have identified them under a microscope as Chlamydomonasnivalis (雪地 衣藻) said the National Antarctic Scientific Centre of Ukraine in a Facebook post.
These green algae (藻类) . a type of seaweed, are common in all icy and snowy regions of Earth, from the Arctic to high mountain regions. They lie still during the freezing winter, but once the sunlight warms enough to soften their world, the algae awake, making use of the melt water and sunlight to rapidly bloom (开花) .
"The algae need liquid water in order to bloom," University of Leeds microbiologist Steffi Lutz told Gizmodo in 2016. "The algal blooms contribute to climate change," the center stated.
A study in 2016 showed that snow algal blooms can decrease the amount of light reflected from the snow by up to 13 percent across one melt season in the Arctic. "This will surely result in higher melt rates,” the researchers wrote.
In 2017 environmental scientists calculated that microbial (微生物的) communities contributed to over a sixth of the snowmelt where they were present in Alaskan ice fields. Their experiments showed that areas with more melt water led to the growth of 50 percent more algae and places with more algae melted further.
This Antarctic summer has certainly seen a lot more melt water than usual. Temperature records keep changing, leading to rapid melting previously only seen in the Northern Hemisphere (半球) .
Questions you should ask yourself when you fail
The more new things we try the more failure we are likely to have.{#blank#}1{#/blank#}. Experiencing failure can be a learning experience and an opportunity for a fresh start. A good way to begin this process is by asking yourself some tough questions.
⑴What can I learn from this?
Take responsibility for what went wrong. OK, so it was not all your fault—but some of it was. Successful people don't make excuses or blame others. {#blank#}2{#/blank#} So you should look at the experience objectively(客观地).
⑵Do I need to acquire or improve some skills?
Did the problem reveal some lack of skill on your part? How could you learn or improve those skills? Perhaps there are books or courses or people you could turn to. {#blank#}3{#/blank#}
⑶Who can I learn from?
Is there someone to whom you can turn for advice? Did a boss, colleague or friend see what happened? {#blank#}4{#/blank#}. Most people do not ask for help because they believe it to be a sign of weakness rather than strength. It's not. It shows that you are ready to learn and change.
⑷What will I do next?
Now draw up an action plan. Will you try something similar or something different? Revisit your goals. Failure doesn't mean you have to give up; maybe you just need to change it in another way. {#blank#}5{#/blank#}
A. You can now reset your sights on your destination and plan a new course. B. Make them step stones to future success. C. They take responsibility for the failure. D. In fact the only way to avoid failure is to do nothing new. E. The important thing is how we deal with failure. F. Make a self-development plan to acquire the skills and experience you need. G. If they are constructive and supportive then ask them for some feedback (反馈) and guidance. |
