The Great Global Warming Debate: Part 1

Since the 1950s, global temperature monitoring has shown a rise in average temperatures. However, the accuracy of these readings was questioned due to urban heat effects. In 1979, satellites were introduced to provide comprehensive global data, but initial results showed cooling, conflicting with thermometer data. An investigation revealed errors in satellite calculations due to their changing altitudes. After corrections, both data sources aligned, confirming a warming trend. Despite some skepticism, the scientific community largely agrees on global warming.

What was a major concern about the thermometer readings taken since the 1950s?

• They were only taken in rural areas.

• They showed a significant cooling trend.

• They were only taken during the winter months.

• They were affected by human development in urban areas.

What was the purpose of launching satellites in 1979?

• To track the movement of tectonic plates.

• To record surface temperatures across the globe.

• To measure the temperature of the oceans.

• To monitor the melting of polar ice caps.

What unexpected result did the initial satellite data show?

• A significant warming trend.

• A slight cooling trend.

• A drastic increase in polar ice.

• No change in global temperatures.

What was the error found in the satellite data calculations?

• The satellites were falling towards the Earth, affecting calculations.

• The satellites were too far from the Earth.

• The satellites were only measuring temperatures at night.

• The satellites were not calibrated correctly.

What is the current consensus among the scientific community regarding global temperatures?

• The data is too unreliable to draw conclusions.

• The planet is warming.

• The planet is cooling.

• There is no significant change.
