New genetic analysis has revealed that many Amazon tree species are likely to survive human-made climate warming in the coming century, contrary to previous findings that temperature increases would cause them to die out. A study,   1  in the latest edition of Ecology and Evolution, reveals the   2  age of some Amazonian tree species -- more than 8 million years -- and   3  shows that they have survived previous periods as warm as many of the global warming imagined periods   4  for the year 2100.

The authors write that, having survived warm periods in the past, the trees will   5  survive future warming, provided there are no other major environmental changes.   6  extreme droughts and forest fires will impact Amazonia as temperatures   7 , the trees will stand the direct impact of higher temperatures. The authors   8  that as well as reducing greenhouse gas emissions to minimize the risk of drought and fire, conservation policy should remain   9  on preventing deforestation（采伐森林）for agriculture and mining.

The study disagrees with other recent researches which predicted tree species’ extinctions   10  relatively small increases in global average air temperatures.

Study co-author Dr Simon Lewis (UCL Geography) said the   11  were good news for Amazon tree species, but warned that drought and over-exploitation of the forest remained major   12  to the Amazon’s future.

Dr Lewis said: “The past cannot be compared directly with the future. while tree species seem likely to   13  higher air temperatures than today, the Amazon forest is being transformed for agriculture and   14 , and what remains is being degraded by logging, and increasingly split up by fields and roads.

“Species will not move as freely in today’s Amazon as they did in previous warm periods, when there was no human   15 . Similarly, today’s climate change is extremely fast, making comparisons with slower changes in the past   16 .”

“With a clearer   17  of the relative risks to the Amazon forest, we   18  that direct human impacts -- such as forest clearances for agriculture or mining -- should remain a key point of conservation policy. We also need more aggressive   19  to reduce greenhouse gas emissions in order to make minimum the risk of drought and fire impacts and   20  the future of most Amazon tree species.”

There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.

People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend (hurt) many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation. It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.

Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrongdoings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact(接觸) with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.
