Due to global warming, more icebergs head for shipping lanes
What the sensible climate pandits had for told years ago has now happened. Thanks to global warming, multitudes of icebergs are making international sea lanes virtual minefields. Dreadful nature of icebergs was fully realised for the first time on the night of April 14, 1912 when the huge passenger liner Titanic after collision with a drifting iceberg, sank in the North Atlantic Ocean. No doubt, invention of devices such as sonar and radar after that disaster considerably increased safety of ships. However, shipping in the northern latitudes is in jeopardy once again. Unlike stray ones in the past, hordes of icebergs have started obstructing the maritime traffic. Whereas primary impact of the greenhouse effect is the rise in the average temperature of Earth, but its varied and woeful side-effects make a long list.
Not to mention animals and birds, even trees have commenced gradual migration towards less warm and humid regions in the north. For example, our most common bird, the house sparrow can be seen in Kazakhstan nowadays. Unprecedented warming of the oceans is instrumental in increasing the frequency of violent cyclones.

All about ‘Lithium Triangle’ and rare-earth elements

China has created artificial shortage forcing many countries including to start a treasure hunt for these minerals. The most sought after is lithium.

Guided missiles: Hitting the bull's-eye with electronic brain
For guns the orders are: ‘Ready! Aim! Fire!’. For missiles, the sequence is: ‘Ready! Fire! Aim!’. It is the aiming part that missiles generally do by themselves. How do they do it? How do they home in on the target?
It is better to initiate discussion on missiles with the question how many types of missiles are there, because the answer to this question will garner much information about them. Basically missile is a sophisticated rocket so its outer framework is not much different from a rocket’s.
