Yes, there is paper and pencil available if you want to do written math calculations, or even to jot down notes for yourself during other sections of the test. The paper and pencil should be provided by the testing center; if itâs not, then you can ask for it.
The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6Â° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years.
But the [climate] models are getting a lot stronger, said Jay Gulledge, a senior research at the Pew Center on Global Climate Change in Arlington, Virginia. Gulledge says some current projections point to a rise in average global temperature of 0.5Â°C (slightly less than 1Â°F) by the year 2030. The estimates are based on greenhouse gasses already in the atmosphere. While the temperature increase is small, it would be significant. Over the past century Earth has warmed about 1Â°F (0.6Â°C). (See our fast facts on global warming.) Gulledge cautions, however, that warming rates depend on many factors, some of which have yet to be discovered.
