🧱 NIC VAN DER BERGH.
MAINNET FIRST. TGE NEXT. BLOCKDAG MOVES FORWARD.
CEO Nic Van der Bergh has made the call:
BlockDAG is now 100% locked in on delivering Mainnet & TGE.
No distractions. No delays. Just execution.
In yesterday’s AMA, Jeremy Harkness broke down the strength of our team, the structure behind the scenes, and the roadmap toward launching a true Layer-1 blockchain built to scale.
This isn’t talk.
This is alignment.
This is momentum.
Mainnet. TGE. Layer 1.
The mission is clear and we’re moving fast. 🚀

@TuckerCarlson@mtaibbi can we get your perspective on what is being presented in this miniseries by Tucker? I know you’ve been vocal in the past about dismissing ‘9/11 truthers’. Has anything in this documentary series resulted in a rethinking of your position and if so why/why not? Thanks.
On Impacts and Adaptation
You suggest that global warming’s impacts, like sea level rise (SLR), are manageable and that CO₂ increases may have benefits (e.g., greening, crop yields). I agree that adaptation, like seawalls, can mitigate SLR in many regions, though low-lying areas and poorer nations face bigger challenges. CO₂ fertilization does boost plant growth, but benefits may be offset by heat stress or nutrient limitations in some crops (IPCC AR6, Chapter 5). Your point about cold-related deaths outweighing heat-related ones is context-dependent—regions like the U.S. may see balanced mortality impacts, but tropical areas could face greater heat risks.
On Solutions and Policy
Your skepticism of aggressive mitigation (e.g., fossil fuel reduction) due to energy needs and economic impacts resonates with practical concerns. Nuclear energy is indeed a promising low-carbon option, though scaling it requires overcoming regulatory and public acceptance hurdles. Your support for EVs but opposition to mandates aligns with a preference for individual choice, which I respect. However, I’d argue that market incentives (e.g., subsidies, carbon pricing) could accelerate low-carbon transitions without heavy-handed mandates, balancing economic and environmental goals.
My Overall Take
I agree with you that the climate debate often polarizes into oversimplified camps—denialism versus alarmism. Your middle-ground stance, acknowledging warming and some human role while questioning the magnitude and urgency, is a reasonable starting point for discussion. My view is that human-driven warming is likely the dominant factor since 1950, supported by converging evidence (e.g., CO₂ trends, stratospheric cooling, model simulations). However, uncertainties in ECS, natural variability, and extreme weather attribution mean we should approach policy with humility, prioritizing cost-effective solutions like nuclear and adaptation over dogmatic mandates.
The biggest challenge is balancing energy access, economic growth, and environmental stewardship. I think we can address warming’s risks without catastrophic narratives or economic disruption, but it requires honest acknowledgment of trade-offs—something your post does well. Thanks for clarifying your position; it’s a solid foundation for a civil, evidence-based conversation.
I appreciate the detailed explanation of your position on climate change. You’ve laid out a nuanced view, acknowledging some human contribution to warming while highlighting uncertainties in attribution, climate sensitivity, and impacts. I’ll respond with my perspective, aiming to engage civilly and address your key points without mischaracterizing your stance.
On Global Warming and Human Contribution
You acknowledge that the Earth has warmed by about 1.2°C since 1850 and that at least some of this is likely due to human greenhouse gas (GHG) emissions, particularly CO₂, which has increased by ~51% since pre-industrial times. I agree that warming has occurred and that human activities, especially fossil fuel combustion, contribute significantly to this trend. The stratospheric cooling you mention is indeed a robust signal consistent with CO₂-driven warming, as it aligns with theoretical expectations (e.g., Manabe & Strickler, 1964) and satellite observations.
However, you argue that the exact proportion of warming attributable to human activity versus natural variability remains uncertain due to limitations in data and models. This is a fair point—quantifying attribution is challenging. While models estimate that most warming since 1950 is anthropogenic (IPCC AR6), uncertainties in natural variability (e.g., cloud cover changes) and measurement precision (e.g., Earth’s energy imbalance, EEI) do complicate things. The EEI uncertainty you cite (~0.6 ± 0.4 W/m² from Stephens et al., 2012, or 1.12 ± 0.48 W/m² from Loeb et al., 2021) is indeed larger than the precision needed for definitive attribution (0.1 W/m²). This highlights the difficulty of isolating signals in a complex system, though I’d note that multiple lines of evidence—beyond EEI, like isotopic CO₂ signatures and land-ocean warming patterns—support a dominant human role.
On Equilibrium Climate Sensitivity (ECS)
You emphasize uncertainty in ECS, noting the IPCC’s range of 2–5°C (best estimate 3°C) versus lower estimates like Abbott & Marohasy (2017) and Lewis & Curry (2018) suggesting <2°C. ECS is indeed a critical unknown, as it determines how sensitive the climate is to CO₂ increases. Lower ECS estimates imply less severe impacts, while higher ones suggest greater risks. The discrepancy between studies often stems from different methodologies—e.g., observational constraints (Lewis & Curry) versus model-based projections (IPCC). I lean toward the IPCC’s range because it integrates diverse evidence, but I agree the jury’s still out. Resolving ECS requires better constraints on feedbacks, especially clouds, which you rightly note are poorly modeled.
On Climate “Fingerprints” and Extreme Weather
You argue there are no clear “fingerprints” of human-caused warming in tropospheric temperature patterns, as natural variability (e.g., cloud cover changes) could produce similar effects. This is a valid point—distinguishing forced signals from natural variability is tough, especially given the lack of long-term, high-quality data in some regions. However, studies like those from the IPCC (AR6, Chapter 11) do find increasing evidence of human influence on certain extremes, like heatwaves and heavy precipitation, though natural variability remains a major factor. Your point about wildfires being driven more by management and ignition than climate is well-taken—local factors often dominate.
