TRUE

FALSE

Changes are due to sunspots or cosmic rays

FALSE

Sunspots are regions of the surface of the star that harbor intense magnetic activity and can be accompanied by solar flares. Although these spots have the ability to modify the Earth's climate, since 1978 scientists have used sensors on satellites to obtain a record of the solar energy reaching the planet and have not observed the existence of an upward trend, so they cannot be the cause of recent global warming.

TRUE

FALSE

The progressive acceleration of global warming threatens to melt the Greenland ice sheet:

TRUE

The research, presented this spring by scientists at the Postdam Institute and the Complutense University, suggests that the accelerated rate of global warming could be close to a tipping point, as the increasing vulnerability of the Greenland ice sheet shows.

TRUE

FALSE

Scientists manipulate data to show rising temperature trend

FALSE

Rather, it is a simplistic maneuver used to attack the credibility of climate scientists. For a conspiracy of these dimensions to be possible, it would be necessary for thousands of scientists from more than 100 countries to agree to lie about the data obtained.

TRUE

FALSE

Climate models are unreliable and overly sensitive to carbon dioxide

FALSE

This statement is incorrect and demonstrates a poor understanding of how the models work, while undervaluing the extent of climate change. There is a wide range of climate models

TRUE

FALSE

Volcanoes emit more CO2 into the atmosphere than human activity

TRUE

It is true that volcanoes emit carbon dioxide and naturally contribute to global warming. However, at the end of the year they emit less than 1% of the total CO2 emissions that pollute the atmosphere, with human activity being the major emitter.
