The Consequences of Global Warming or Global Climate Change
Scientists have high confidence that global temperatures will continue to rise for decades to come.
This is largely due to:
•Greenhouse gases produced by human activities •Orbital Variations
The change will occur over this century and beyond.
The magnitude of global climate change depends on the amount of heat-trapping gases emitted globally, and how sensitive the Earth’s climate is to those emissions.
