Iceberg twice the size of Washington, D.C., breaks off Pine Island glacier in Antarctica

Story Highlights:

• The Pine Island glacier "is one the fastest-retreating glaciers in Antarctica."
• Over the past 8 years, the Pine Island glacier is losing about 58 billion tons of ice per year.
• This "reveals the dramatic pace at which climate is redefining the face of Antarctica."

Climate Feedback Clam Review...

CO2 emissions from human activities have imbalanced the atmospheric carbon budget, significantly contributing to climate change, contrary to online claim

CLAIM: "Less than 5% of carbon dioxide emissions are produced by man [... they] can’t cause 30% of today’s atmospheric carbon dioxide"

SOURCE: A Short List Of Facts Global Warming Alarmists Don’t Want To Face, Opinion by Editorial Board, Issues & Insights, Aug 26, 2019

VERDICT:  

KEY TAKE AWAY: Carbon dioxide is a greenhouse gas released by natural processes as well as by human activities. The rapid rise in carbon emissions from burning fossil fuels beginning during the Industrial Revolution upset the natural balance in the global carbon cycle. Human-caused carbon emissions outpaced the ability of natural carbon sinks to absorb excess carbon dioxide, resulting in a rise in atmospheric concentrations from 280 to about 415 parts per million in 2020.
