New Study Affirms Anthropogenic CO2 Emissions Play No Role In Larsen Ice Shelf Melt

There are four main reasons why Antarctica’s Larsen C Ice Shelf may be melting. None of them involve human forcing or CO2 concentration changes.

Scientists have recently completed an exhaustive 20-year study of the “most significant causes of melting” of the Larsen C Ice Shelf in the Antarctic Peninsula. They have concluded the 4 main surface melt drivers are:

1. Shortwave solar radiation.

2. Foehn wind variations.

3. Cloud cover changes.

4. Natural circulation variations (SAM, ENSO).

Neither anthropogenic forcing nor CO2 emissions are listed as causal factors in Antarctic ice melt processes.

Until 1000 to 2000 years ago, Antarctica was up to 5°C warmer than it is presently. Open-water conditions prevailed throughout most of the Holocene (the last 11,700 years) in the same area where the massive Larsen Ice Shelf exists today (Domack et al., 2001).

In other words, there is nothing even remotely unusual about any Antarctic ice melt or climate trends that cannot be explained by or attributed to natural, non-anthropogenic processes.

    CO2 encourages plant growth and oxygen production, period. The anthropogenic CO2 narrative has long been proven and shown to lack any real scientific credibility. All this over and above the currently ongoing 20 year period of solar cycle cooling between now and 2040.

      1000% agree.

    “the 4 main surface melt drivers are:

    But every one of these is caused by Man Made CO2! Please send money so that I can do the research to prove this.

    Lots of money.

      (By “research” I mean “set up a computer model”. So I need enough money to buy a super-computer.)

    How about underseas volcanoes?
    That’s my first thought when I hear ice shelf melting
