225,000 years ago is the MIDDLE of that chart. Not 'the far right' or 'to the right of your last ice volume "peak"'

While I don't agree with Tug on a lot of stuff, you're clearly either missing or attempting to obscure the valid point he's making.

 

[dik]

Swinny... You may not be aware that 225,000 years ago, there were no people in California... people in the Americas are only a recent addition... about 20,000 years ago. What's his valid point? The data could be valid and unbiased, but for the most part is meaningless... Only the extreme RHS is applicable to people in California. I didn't miss anything.

The problem I see with the geological historical record is that it is pretty meaningless compared to recent impacts. Coal consumption really kicked off since the 50s, following a trend that really looks unsustainable. This is, IMHO, way too short of a timescale to have any impact on climate, but to change we had to have definitive statements .... yes, yes we've been burning coal and gasoline since 1850s but in much smaller quantities. I think I read that 75% of CO2 has been emitted in the last 70 years.

Dik, if you read the image I shared, it says that humans were living in the vicinity of San Diego 130,000 years ago.

Why should we ignore everything but the extreme RHS? There seems to be a very clear pattern. In every previous warming, notice how steep the slopes are. It's exactly the same as what we are seeing today.

 

[dik]

You might want to check your source... most credible info regarding people in the Americas indicates they arrived about 20,000 years back. It's only the extreme RHS that might have an impact on people living there... the early weather/climate would have little impact on them.

That's it, the oldest artifacts have already been found? Nothing older will ever be discovered?

Interestingly, 130k years ago corresponds with a warmest period. Perhaps the world was more hospitable and able to support a more diverse range of hominids over a wider habit.

Things are starting to heat up... in Texas, too. More GHGs...:

for added climate info...

"As global warming accelerates, decisions on infrastructure, energy, mobility, water and food security or urban planning need to be informed by the potential impacts of climate change. The Copernicus Climate Change Service (C3S) ERA5 reanalysis dataset provides key insights about our past and present climate, helping to foresee the risks, and assisting policymakers in making informed decisions.

The consequences of climate change, anticipated by scientists many years ago, have become a part of our everyday lives. Throughout 2023, almost every corner of the world was affected, and nearly every individual has witnessed, to varying degrees, an increase in the frequency or intensity of extreme weather occurrences such as heatwaves, wildfires, droughts, or heavy rainfall. This transformation is occurring rapidly, and so we need swift adjustments in policies."

[TugboatEng]

Is 1940 really considering "past climate change"? Shouldn't they look back a little further of they want to make meaningful observations?

 

[dik]

1940 is still part if our current climate change... most of the 'stuff' has happened in the last decade or so...

[TugboatEng]

Totally not true. We've already established that most of the stuff happened over the last 12,500 years.

 

[dik]

...maybe a lot within the last decade?

You're going to tell me that the last 410 feet of sea level rise is irrelevant while whining about a completely imperceptible rise between 1940 and now?

 

[JoshPlumSE]

You're going to tell me that the last 410 feet of sea level rise is irrelevant while whining about a completely imperceptible rise between 1940 and now?

Anything that doesn't fit the narrative is irrelevant.

I have said this before, but to the radical left the very real issue of climate change doesn't matter. The only thing that matters is how they USE that issue to further the revolution, seize power, fundamentally change our society, destroy capitalism or however you want to characterize their political goals. The issue is NEVER the issue, the issue is POWER.

Note: I'm not saying that dik is a radical lefty. He genuinely believes in the importance of this issue, as do I. We really only differ in the solutions and the best way to get there. In that way, he's more of a victim of the radical left narrative.

 

[Ron247]

I periodically read this site on eng-tips. What does "RHS" stand for? I guess I missed when it was defined.

 

[dik]

Right Hand Side... as opposed to LHS.

dik,

That is insulting. Your conscience is yours, my conscience is mine.

Great Barrier Reef News... "I'm not dead yet" with apologies to Monty Python...

"Australia's iconic Great Barrier Reef is suffering another mass bleaching event, officials have confirmed.

Often fatal, bleaching occurs when heat-stressed corals expel the algae that gives them life and colour.

It is the fifth time in eight years widespread damage has been detected at the Unesco World Heritage site.

Only two mass bleaching events had ever been recorded until 2016, and scientists say urgent climate action is needed if the reef is to survive.

Stretching over 2,300km (1,400 miles) off Australia's north-east coast, the Great Barrier Reef is the world's largest coral system and one of its most biodiverse ecosystems.

It has been World Heritage-listed for over 40 years due to its "enormous scientific and intrinsic importance", but Unesco says the icon is under "serious threat"."

"Claims that Australia is taking the health of the Great Barrier Reef seriously ring hollow when we continue to expand and subsidise the coal and gas industry to the tune of billions every year."
