1. Explique, com suas palavras, como acontece o efeito estufa e destaque a principal consequência
desse fenômeno para o meio ambiente.
2. Considere o aumento de temperatura (em grau Celsius) como função do tempo (em ano) e a concen-
tração de CO₂ na atmosfera (em ppm) como função do tempo (em ano
). É possível identificar algum
período de tempo em que a
temperatura terrestre e a concentração de CO, tenham aumentado de
forma mais acelerada? Quais
são as possíveis causas desse aumento?
3. Converse com os colegas sobre formas alternativas de combustível que permitam reduzir as emis-
sões de poluentes nocivos ao meio ambiente e reflita sobre os impactos dessas alternativas conside
rando diferentes perspectivas, como a de países desenvolvidos, países em desenvolvimento e países
subdesenvolvidos.
4. Em abril de 2017, encerrou-se o período oficial de assinatura do Acordo
de Paris, que tem o objetivo de combater as mudanças climáticas que
vêm ocorrendo no planeta. Pesquise quais medidas serão tomadas para
alcançar os objetivos e quais foram os países signatários. Discuta com os
colegas sobre a relevância desse comprometimento global e divulgue as
informações obtidas por meio de cartazes e outros recursos.

Final answer:

The greenhouse effect leads to global warming with significant consequences. Human activities have accelerated temperature and CO2 levels. Exploring alternative fuels and the Paris Agreement are crucial for combating climate change.


Explanation:

Global Climate Change: Understanding the Greenhouse Effect and Consequences

  1. Greenhouse Effect: The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat from the sun, leading to a warming effect on the planet. The primary consequence of this phenomenon is global warming, resulting in rising temperatures, melting ice caps, altered weather patterns, and disruptions to ecosystems.
  2. Acceleration of Temperature and CO2 Concentration: There are periods in history where temperature and CO₂ concentration increased rapidly. This acceleration is often linked to human activities like industrialization, deforestation, and the burning of fossil fuels, which release large amounts of greenhouse gases into the atmosphere.
  3. Alternative Fuels and Emission Reduction: Exploring alternative fuels such as solar, wind, and hydroelectric power can help reduce harmful emissions, benefiting the environment. However, the adoption of these alternatives may vary in impact and feasibility among developed, developing, and underdeveloped countries.
  4. Paris Agreement: The Paris Agreement aims to combat climate change by setting emissions reduction targets. Countries that signed this agreement pledge to take specific actions to limit global temperature rise. The commitment to this global effort is crucial in addressing the ongoing climate crisis.
