Transcript
Climate Change Catholic Social Teaching Document #: TX002033 Climate Change • Climate change happens slowly and is not noticeable until after many decades. • Climate changes occur due to human activities and natural causes. Natural Climate Change • Climate changes result from natural causes such as changes in ocean patterns, Earth’s orbit, volcanic eruptions, and the sun’s intensity. • Changes in Earth’s orbit affect the amount of sunlight absorption on Earth. • Differences in the sun’s intensity or the sun’s rays cause warmer weather with higher intensity or cooler temperatures with lower intensity, respectively. • Volcanic eruptions result in gas releases such as aerosol and carbon dioxide. Human Activity and Climate Change • Human activities such as deforestation and the burning of fossil fuels change the atmosphere’s composition. • Human activities that release greenhouse gases lead to climate changes. • Human activity in the last century seems to have accelerated climate change. • Climate change caused by human activity is both a threat to creation and a symptom of damage to creation. Effects of Climate Change • Climate change affects the environment and the ecosystem. • When the climate changes, farmers have a hard time adapting to the changes. • Changes in the weather can lead to droughts, changes in irrigation, water quality, and fish farming.
