What do France and Bangladesh have in common in Paragraphs J and K? J       Meanwhile some governments have taken small but important steps to better prepare for extreme weather. An exceptional heat wave in Europe in 2003 took at least 35,000 lives; a later analysis found that climate change had doubled the odds of such a disaster. Afterward French cities set up air-conditioned shelters and identified older people who would need transportation to the shelters. When another heat wave hit France in 2006, the death rate was two-thirds lower. K      Similarly, after a tropical storm killed as many as 500,000 people in Bangladesh in 1970, the government there developed an early warning system and built basic concrete shelters for evacuated families. When cyclones hit today, the death count stays in the thousands.

What is the source of data for the record-breaking disasters mentioned in Paragraph G? G      But natural cycles can’t by themselves explain the recent streak of record-breaking disasters. Something else is happening too: The Earth is steadily getting warmer, with significantly more moisture in the atmosphere. Decades of observations from the summit of Mauna Loa in Hawaii, as well as from thousands of other weather stations, satellites, ships, buoys, deep-ocean probes, and balloons, show that a long-term buildup of greenhouse gases in the atmosphere is trapping heat and warming up the land, oceans, and atmosphere. Although some places, notably the Arctic, are warming faster than others, the average surface temperature worldwide has risen nearly one degree Fahrenheit in the past four decades. In 2010 it reached 58.12°F, tying the record set in 2005.
