However, current climate change is due to anthropogenic (human-made) sources of recent decades. Winds generated by atmospheric circulation help transport heat throughout the Earth. Oceanic currents, or the ocean conveyor belt, carry heat throughout the world. Climate change affects circulation patterns in wind and oceans, which influences global weather patterns. Earth's polar regions are responsible for reflecting sunlight and heat back to space, but with sea ice dwindling, more heat is building in the polar regions, increasing global warming. This positive feedback loop is melting more sea ice and thawing tundra, releasing greenhouse gases like methane, which increases global warming even further. Some effects of climate change include rising temperatures, melting permafrost and sea ice, rising sea levels, disrupted marine and polar ecosystems, and displacement of coastal populations. Climate change can also affect soil through changes in temperature and rainfall, which can impact soil's viability and potentially increase erosion. For this lesson's science skills, you interpreted data evidence to support the theory that current climate change is due to anthropogenic (human-made) sources of recent decades. 2 Global Climate Change Lab Lab Activity You know that greenhouse gases absorb and emit infrared radiation in our atmosphere. The effect of these greenhouse gases is to warm the atmosphere to the life-friendly temperatures we expect on Earth. Without these greenhouse gases, Earth's temperature would be too cold to support life as we know it. However, the global climate has become warmer in recent decades. Carbon dioxide and water vapor, both of which are greenhouse gases, are products of fossil fuel combustion. Scientists are looking closely at the connection between increased fossil fuel use, the

In this virtual lab activity, you will examine the effects of increasing greenhouse gas concentrations to Earth’s atmosphere and determine how this increase is affecting Earth’s climate. You will also discuss the consequences of climate change to Earth’s biosphere.
