Was the IPCC always corrupt, no... but their blatant omission of past climate data that doesn't fit the "climate crisis" 
narrative tells a different story. They seem complicit in creating panic by ignoring history. Read more below.

Forgotten Extremes: The Megadroughts the IPCC Ignores

Every heatwave, drought, or wildfire today instantly generates alarming headlines blaming human-induced climate change, complete 
with apocalyptic warnings about supposedly "unprecedented" events. Take, for instance, recent headlines like BBC's alarming 
narrative about heatwaves, drought, and wildfires, explicitly linking these natural phenomena to modern industrial activity. But 
what happens when we dare to look deeper into the historical record?

What emerges from such scrutiny is a starkly different story. Virtually every extreme climate event labeled as evidence of 
catastrophic human influence today has occurred naturally in the past-often with greater severity.

The Forgotten Megadroughts of Ancient Mexico

Consider the meticulously documented case of Cantona, a major pre-Columbian city in Mexico. As detailed in a robust scientific 
study by Bhattacharya et al. (2015) in the Proceedings of the National Academy of Sciences, Cantona thrived from around 600 BCE 
to roughly 1050 CE, peaking at 90,000 inhabitants before dramatically collapsing. This abandonment coincided precisely with one 
of the region's longest and most intense droughts, lasting from approximately 500 CE to 1150 CE.

Using advanced geochemical methods, researchers analyzed lake sediment cores from the nearby Aljojuca Lake, employing stable 
oxygen isotopes (d¹8O) and sediment aluminum concentrations to reconstruct past climate conditions. Their findings reveal an 
extended period of severe aridity lasting centuries, far more prolonged and severe than recent droughts blamed on human activity. 
Figure 2 from their study explicitly illustrates how peak drought coincided with Cantona's abandonment, underlining the severity 
and persistence of this historic climate extreme.

to multiproxy paleoenvironmental evidence. Heavy black lines represent a four-point moving average filter. (B) Mass % Al2O3, 
indicative of rain-induced slopewash; (C) d18O, representative of E/P ratios; (D) high-spine Asteraceae pollen, which may be an

pollen at a particular level. Source: https://www.pnas.org/doi/full/10.1073/pnas.1405653112

Having used oxygen isotopes extensively myself, specifically analyzing the mineral zircon to reconstruct ancient magmatic 
conditions, I can attest firsthand to the reliability and robustness of such paleoclimatic reconstructions.

Modern Drought Narratives: Ignoring Historical Evidence

Yet, despite this clear historical record, modern droughts in Mexico are habitually attributed to anthropogenic climate change 
without a hint of historical perspective. For example...

Climate Change/Global Warming/CO² Explains EVERYTHING!

Climate Change/Global Warming/CO² makes for shorter winters, except for when it makes for longer winters. 

Climate Change/Global Warming/CO² means less snow, except for when Climate Change/Global Warming/CO² means more snow. 

And Climate Change/Global Warming/CO² causes droughts in California and floods in Texas and Oklahoma and generally makes wet 
places wetter and dry places dryer, except when it makes wet places drier and dry places wetter, except when none of that changes 
at all, and then Climate Change/Global Warming/CO² explains that too! 

And Climate Change/Global Warming/CO² causes more hurricanes at the same time as it causes less hurricanes. 

Climate Change/Global Warming/CO² causes more rain but less water... and less rain but more water?

And Climate Change/Global Warming/CO² causes more water vapour in the atmosphere, at the same time it causes less rain... and 
less water vapour in the atmosphere, when it causes MORE rain? 

Climate Change/Global Warming/CO² decreases the spread of malaria at the same time as it increases the spread of malaria. 

Climate Change/Global Warming/CO² makes San Francisco foggier... Climate Change/Global Warming/CO² makes San Francisco less 
foggy. 

Climate Change/Global Warming/CO² causes duller autumn leaves... Climate Change/Global Warming/CO² causes shinier autumn leaves. 

Climate Change/Global Warming/CO² makes for less salty seas... Climate Change/Global Warming/CO² makes for saltier seas. 

Climate Change/Global Warming/CO² causes the polar ice caps to melt... Climate Change/Global Warming/CO² also causes the polar 
ice caps to freeze. 

Climate Change/Global Warming/CO² makes the Earth hotter, unless the Earth isn't getting hotter... in which case, Climate 
Change/Global Warming/CO² can explain that too. 

What's the problem here? This sounds like the perfect scientific theory. It can explain literally everything including self 
contradictory things. 

This means it's absolutely perfect, doesn't it? 

Well no, not according to Karl Popper and the philosophers of science and within the philosophy of science there's something 
called the demarcation problem... how do you differentiate science from pseudo-science? 

The left won't LET you, and brands you a denierrrrrrr(whining).
