Who uses our Fuel?

In our country, the focus seems to be on reducing the use of petrol in passenger vehicles. While this segment represents a significant portion of our consumption at about 140 billion gallons per year, it does not represent the majority of usage. Our airline industry uses over 100 billion, Ocean freight over 100 billion and commercial land freight uses over 53 billion. While there are other usages these four represent the vast majority. While we are making significant progress with both EV technology and application we must recognize that we are only dealing with about a third of the issue.

The solutions for Ocean Freight seem to be “decarbonization”:  https://old.geodis.com/us/blog/air-ocean-transport/reducing-environmental-footprint-ocean-freight

The focus of the airlines seems to be on a sustainable fuel source that reduces fossil fuel consumption, but does little to deal with the carbon emission issue: https://www.4air.aero/saf-map?gclid=Cj0KCQiA3uGqBhDdARIsAFeJ5r2HXEbjZOdCiPRkTKaHeChZef0mvM0ZBgUoMMJQF4ZQu0EUkK_yRxAaAk8LEALw_wcB

Note: We export about ½ of the oil we produce. I’m depressed.

Mega wind turbine

World’s Largest Wind Turbine

16 MW offshore wind turbine begins operations off east China coast 

In the week that it was announced that Rishi Sunak will be granting new oil and gas licenses in the North Sea, new commitments to renewable energy are being made elsewhere in the world.

The China Three Gorges Corporation just turned on a mega wind turbine with blades twice the size of a football pitch in the Taiwan Strait. The state-owned energy firm has activated the biggest wind turbine on the planet offshore in a move that could produce up to 16 megawatts of energy, and it’s now been connected and hooked up to the energy grid

The inconvenient truth

The inconvenient truth of global warming in the 21st century

Based on data since 2000 alone, global warming is still occurring at a whopping 7-sigma significance. How hot will planet Earth get?

A hypothetical map of what an ice-free Earth would look like, with all glaciers, ice sheets and icecaps fully melted. The mean sea level is a full 67.5 meters (221.5 feet) higher than it is today. Thermal expansion of the oceans would exacerbate this effect, but this view of a future Earth is not a foregone conclusion in the coming millennia.(Credit: Kevin Gill/Flickr)

KEY TAKEAWAYS

  • Toward the end of the 20th century, there was a lot of dissent and argument over the scientifically robust evidence that showed the Earth is warming. 
  • The evidence of this warming is so strong that even if we begin in the year 2000, it’s robust at the 7-sigma level, with less than 1-in-100 billion chance of it being a statistical fluke. 
  • We’re now at the point that we have to ask ourselves when we want Earth’s hottest year of the 3rd millennium to be. We’re capable of determining the answer.

Back in 1990, with 110 years of temperature records behind them, the world’s top climate scientists convened to put together a report on the state of the Earth’s climate. Working collaboratively, the fruits of their labor became the very first Intergovernmental Panel on Climate Change (IPCC) report. It definitively showed:

  • there had been a global increase in carbon dioxide concentrations since pre-industrial times from ~280 parts-per-million (ppm) to 354 ppm,
  • this was coupled with a global average temperature increase of 0.7 °C (1.3 °F),
  • that the increase in temperature was being driven not by the Sun, volcanoes, or urbanization, but rather by the human-wrought changes to our atmospheric contents,
  • and that this problem would continue to worsen unless carbon dioxide emissions were curbed.

Despite sounding the alarm, the past three decades have led to a far more dire situation. As identified in 2021’s 6th IPCC report, carbon dioxide concentrations now sit at 412 ppm, Earth’s average temperature is a full 1.3 °C (2.3 °F) above pre-industrial levels, and our global carbon emissions have increased to a new all-time high: nearing 40 billion tonnes of carbon dioxide annually, up from 22 billion in 1990. The best time to act was long ago, but the second best time to act is now.
