World's hottest ever month recorded
Lake Arlington, Texas: water level is 13ft below normal
Figures published in the United States show that July was the world's hottest month ever recorded.
The temperature was 1.26 °F higher than the long-term average for July and 0.45 °F higher than previous record for the month, set in 1997.
In the US, parts of Texas had 29 consecutive days with temperatures above 100°F (38° C).
Tackling global warming
Announcing the figures, Mr Gore said: "The good news is we can stop this."
"We know what to do ... It will be hard, but we can do something about it. If we do not do something about it, then what we have been experiencing this summer ... is going to get to be a lot more common, and it will get worse."
But the Clinton administration has yet to persuade Congress to ratify the Kyoto agreement, which calls for industrial nations to cut greenhouse gas emissions by an average of 5% below 1990 levels by the year 2010.
US opponents say the treaty would hurt the American economy and favour developing nations.
The White House has decided to delay submitting the treaty to the Senate until it convinces developing nations, including China, to accept limits on emissions.
