2. Atmospheric Counter Clock Wise rotations have air masses dropping down from the stratosphere. _______

3. Air that drops down from the upper atmosphere can come down so fast it does not have time to warm up. _______

4. Storm related, ocean storm surges, can be hundreds of feet high _______

5. World wide climatic shifts are known to happen extremely fast. _______

6. Polar ice cap ice shelves have been observed cracking and breaking up _______

Explanation / Answer

1). TRUE

Climate models help us to understand our present weather and climate, and also allow us to consider plausible future scenarios of how the climate might change. They generate simulations to tell us what happened or what might happen under a range of different scenarios, such as for greenhouse gas concentrations

2). FALSE

3). FALSE

When the warm air rises, the speed of those air molecules slows down just like a ball that is thrown into the air slows down. The molecules convert their kinetic energy into potential energy when they rise into the air just like the ball did. And since temperature is a measure of kinetic energy, the lower kinetic energy means a lower temperature and vice versa.

4). FALSE

The highest storm tide noted in historical accounts was produced by the 1899 Cyclone Mahina, estimated at almost 44 ft (13 metres) at Bathurst Bay, Australia

5). TRUE

An abrupt climate change occurs when the climate system is forced to transition to a new climate state at a rate that is determined by the climate system energy-balance, and which is more rapid than the rate of change of the external forcing. Past events include the end of the Carboniferous Rainforest Collapse, Younger Dryas, Dansgaard-Oeschger events, Heinrich events and possibly also the Paleocene–Eocene Thermal Maximum.

6).TRUE

The break-up of vast ice shelves in the Antarctic – such as the recent massive iceberg – is being fuelled by a wave that moves at about half the speed of a bullet, according to a new study.
