Scientists say the frozen continent is likely to ‘alter rapidly under future warming, leading to major changes in the biology and landscape of this iconic region. The Antarctic is turning green with rising temperatures having a “dramatic effect” on the growth of moss in the frozen continent, scientists have discovered. Since 1950, temperatures in the Antarctic Peninsula have risen by about half a degree Celsius each decade. This is much faster than the global average.
Growth rates of moss since 1950 have been running at four to five times the level before. This is according to a study by UK-based researchers who studied three sites across a 1,000km stretch of the peninsula. In addition to climate change, the extinction of animal species is prolific. Plastic waste, fossil fuel ash and radioactive particles from nuclear bomb tests will all leave a permanent record in the planet’s future rocks.
“Between 1950 and 2000, temperatures increased by half a degree per decade on average,” said Dr Amesbury of Exeter University. “The reason we are so confident the moss is responding primarily to temperature, is because of the wide-scale response we see in our moss banks from three different sites that stretch 1,000km across the Antarctic Peninsula.”
The researchers who reported the results of their study in an open-access paper in the journal “Cell Biology”, also looked into how sensitive the moss would be to further warming. “The results of that analysis lead us to believe there will be a future ‘greening’ of the Antarctic and a further increase in moss growth rates. “We are likely to see massive amounts of moss colonizing new areas of ice-free land created by the warmer climate.
The first Antarctic land discovered was the island of South Georgia, visited by the English merchant Anthony de la Roché in 1675. Although myths and speculation about a Terra Australis (“Southern Land”) date back to antiquity, the first confirmed sighting of the continent of Antarctica is commonly accepted to have occurred in 1820 by a Russian expedition. The first human born in the Antarctic was Solveig Jacobsen. He was born on 8 October 1913 in South Georgia.
The Antarctic region had no indigenous population when first discovered. It’s present inhabitants comprise of just a few thousand transient scientific and other personnel. They work on tours of duty at several dozen research stations maintained by various countries. However, the region is visited by more than 40,000 tourists annually, the most popular destinations being the Antarctic Peninsula area (notably the South Shetland Islands) and South Georgia Island.
In December 2009, it was noted that the growth of tourism, brought along with it, consequences for both the ecology and the safety of the travelers in its great and remote wilderness. This was at a conference in New Zealand conducted by experts and signatories of the Antarctic Treaty. The definitive results of the New Zealand conference were presented at the Antarctic Treaty states’ meeting in Uruguay in May 2010.
Leading statements and questions
For learners of a second language, sometimes, dialog or conversation can be difficult. Conversation engagement, is not that difficult with a few simple tricks. Asking a simple question to start out a conversation is easy with simple question words. I covered question words in a previous English Club.
Question words are often needed to carry on a conversation. The idea is to ask questions connected to details already mentioned. Try to do this while the other person is speaking. This is easy by visualizing objects and situations that are connected.
I call these “Leading Statements and Questions”. It is all about dialog and how to continue a conversation. Now, we go back to those questions words and how they connect. Here’s an idea and example. “What is your favorite food?”. An answer might be “My favorite food is pizza”. Now visualize in your thoughts “What kind of pizza do you like?”. Another question could be; “How often do you eat pizza?” or “Where do you eat pizza?” or “What is your favorite pizza?” or “Why is pizza your favorite?”
You can ask many questions with question words with leading questions and visual thoughts. Here! Take a look at a few examples with our speaking practice…
Creating Dialog with Leading Questions
Notice how I focus on the “Park” and “Connections” to the park along with other details relating to the park.
Leading questions are easy when you get the hang of it. Practice questions in English and keep the conversation going.
Basic Grammar Review
Prepositions of Place, Movement and Time
English prepositions are always fun to learn. It helps if a teacher has classroom teaching aides to assist with examples. Classroom posters are another way for students to learn from and have a reference point when working with a teacher and fellow students. English prepositions are all about place, movement and time. Before getting started with prepositions, there are two important words to teach as thoroughly as possible.
Start with the word “Arbitrary”. The word arbitrary is used when we refer to something when relevance is not exact. In this case, the word’s “something or anything are indefinite”. The main objective here is to help students better understand that, when describing with prepositions, often there is more than one choice. In other words, examples like “Please sit near the table or by the table” have little difference in meaning. The main idea is to learn how to communicate. If we both understand what the other is saying; isn’t that perfect English? Or better yet! Perfect communication.
The second important word to learn is “Collocation”. Collocations or colloquial speech is when we use words in a certain order that are common in English. Commonly spoken word combinations are easier to understand than one might think. Collocations can be used many different ways in English. Common statements, phrasal verbs and the list goes on and on. One of the best ways to teach collocations and common word order is with a list of examples. This is done in order of importance. In other words, start by writing a simple statement with the most popular word combination or collocation. Examples might include, “Please have a seat at the table” or “Please have a seat by the table”.
Although these statements mean two different things, they are used universally. The main idea here is “Which word combination is used more commonly?”. Please sit “AT” the table is more common compared to; Please sit “BY” the table. Therefore “AT” is more common compared to “BY”. Can we use both examples? Yes! Why? Because, I understand you!
One other important element is the simple fact that we commonly use prepositions three primary ways. That would be for “Place, Movement and Time”. Generally, when studying this subject, it is often easier to keep time prepositions until last.
Typical time expressions are all about colloquial speech. Place and movement prepositions are generally specific to places and movement but, many can be interchanged. This is due to the difference between perfect grammar and spoken English. Again, it is often more important to communicate understandably, than to attempt to speak perfect English.
So, which prepositions are the ones we should start with and why teach prepositions in chunks? There are three to start with. Those would be “At, In, On”. These are the three most common prepositions. One of the best ways to learn prepositions is to connect them with understandable words. In other words; Vocabulary that you already know.
In English, there are many methods of teaching grammar. The main idea is to ask questions. Why do we use the word “AT?” “We use the word “AT” with locations or places”. Why do we use the word “IN?” “We use the word “IN” with limits”. Why do we use the word “ON?” “We use the word “ON” when two things touch”. These are common examples and general thoughts. There are exceptions to just about every rule in English. Just remember collocations and flexible English.
Choose other preposition words to chunk together and form common ways to describe identical situations. All students need to know that while all speech is important, the main goal should always be understandable communication. If an expression or statement is not perfect English but, the other fully understands your statement, isn’t that perfect English?
A few simple thoughts about “Reported Speech”. There are two ways to report what happened or what someone said, “Direct Reported Speech” and “In-direct Reported Speech”.
Direct reported speech is used when we use the same tense when stated. In other words, if someone says “Hello”, we can refer to the statement with something like “He says hello!”. In this example, we use the same tense as what was said.
“Indirect reported speech” is when we refer to a statement or fact from the past and go back one tense in our statement. So, if someone said “I am hungry” we would say “He said he was hungry”. Notice how the verb “To be” changed from “Am to Was”. In this example, we went back one tense to refer to what was said.
Another important element to “Reported Speech” is when we use “Modal Auxiliary Verbs”. In direct speech, we use the same modal verb used. In other words, if someone something like “I will go to work next week”, you report with the same modal verb. If you report with indirect speech, use “Would”. So, will to would, can to could, may to might and so on.
This is just a short explanation for reported speech. For more information regarding reported speech, look for grammar books at the Intermediate level and above.
