El gran debate sobre el calentamiento global (primera parte)

Since the 1950s, global temperature data has shown a slight increase, but some scientists questioned its accuracy due to urban thermometer placements. Satellites launched in 1979 aimed to provide comprehensive data but initially showed cooling, conflicting with thermometer data. An error in satellite calculations was found and corrected, aligning both data sources to show a warming trend. The scientific community now largely agrees on global warming, though some skepticism remains.

What factor might have caused inaccuracies in thermometer readings in urban areas?

• The height at which thermometers were placed

• Human development around the thermometers

• The color of the thermometers

• The type of thermometers used

Why were satellites launched in 1979 to measure global temperatures?

• To replace outdated thermometers

• To measure temperatures in uninhabited areas

• To study the effects of pollution

• To observe weather patterns

What unexpected trend did the satellite data initially show?

• A significant warming trend

• A stable temperature trend

• A slight cooling trend

• No change in temperature

What was the error found in the satellite data?

• The satellites were measuring the wrong area

• The satellites were too far from Earth

• The satellites were descending towards Earth

• The satellites were not calibrated correctly

What conclusion did the scientific community reach after correcting the satellite data?

• The Earth's temperature is stable

• The Earth is warming

• The data is inconclusive

• The Earth is cooling
