I have worked on the slowing and the tipping point of the #AMOC since 1991. Here is what we know now - the short 15 minute summary. AMOC slowing is already affecting our weather. The AMOC tipping point may change your childrens' life. /5

Is This the ABSOLUTE Worst Case Tipping Point? The science behind runaway greenhouse effects, ancient volcanic carbon releases, and one of the most surprising climate wildcards scientists have discovered: the potential collapse of stratocumulus clouds‼️ Credit: Maiya May ― PBS

There’s Something MUCH Bigger Than Yellowstone. And It Will Happen Again. There’s something so powerful it’s been linked to nearly every mass extinction in Earth’s history. Astonishingly, most people have never heard of it, a massive large igneous event. Credit: Maiya May ― PBS

"Lagos is a coastal state, and we are exposed to the vagaries of climate change; we cannot run away from it. Some parts of Lagos are below sea level. Once there is climate change, there is excessive rainfall, excessive heat, and there is tidal lock because there is a sea level rise." — Tokunbo Wahab, Lagos commissioner for environment and water resources

NEW: Alameda City, CA, mayor appears to suggest her city will be underwater because of Climate Change unless the government reopens. "The kind of assistance we need from the federal government is not to send troops..." said Mayor Marilyn Ezzy Ashcraft. "It's anyone's guess when that funding will resume ... Alameda is an island, but the entire region needs to be concerned about Climate Change and sea level rise." "As I like to say to my fellow electeds, even if you don't live in a waterfront community, if we don't do something about climate change and sea level rise, you will."

Antarctica’s Collapse May Have Already Begun Antarctica is melting and one of its largest glaciers is collapsing from underneath. Thwaites could trigger a wider collapse of the full West Antarctic ice sheet, raising sea levels by 5 meters. Credit: Russell Arnott ― New Scientist

The “Cold Blob” and talk of the collapse of a vital ocean current has been all over the news lately. New research confirms the peculiar cold blob is a canary in a coalmine for our climate. A collapse would cause climate chaos. But how likely is it? Here’s a very simple video about how the AMOC works, the latest science, the tipping point, and what collapse would mean to Earth’s climate. #AMOC #climatechange #science #STEM

Yes, the Rise of the Triad demo is NOT TIMED and will stay up FOREVER. We may even update it over time! This is our SHAREWARE version of the remaster. So please enjoy it - AND SHARE IT :)

Climate science may have made a BIG mistake! New research using the most comprehensive global dataset yet on biological nitrogen fixation suggests that one of the climate system’s most reassuring assumptions — the idea that rising CO₂ will significantly boost plant growth and help absorb our emissions — may have been significantly overstated. Plants will still absorb carbon, but the gap between what we emit and what nature can safely take up may be a lot wider than we once thought. Credit: Dave Borlace ― Just Have a Think

Climate change is not just a change in the weather. It is changing life on our planet. It is killing people and devastating communities. To limit global temperature rise, we must phase out coal, oil & gas in a fair & equitable way – and massively boost renewables. #UNGA

For years, the Intergovernmental Panel on Climate Change, or IPCC, has claimed that human-caused climate change has accelerated sea level rise. But that claim is false. There is no scientific evidence of accelerated sea level rise since the mid-19th Century, and thus none showing human-created emissions caused an acceleration in recent decades. This does not mean that climate change isn’t happening. It is. It simply means that it has not caused the sea level to rise at a rate any higher than one would expect without human-caused climate change. Not only that, but the top scientists know this fact and have deliberately misrepresented it for years, deceiving the public. In September, I reported on one of the first global studies of sea level rise that used tide-gauge data, which is the only real-world data that goes back long enough, to the mid-19th Century, that would allow one to detect whether sea level rise had accelerated, decelerated, or remained steady. Since then, I exchanged over 50 emails with one of the world’s leading sea level rise scientists, Robert Kopp from Rutgers University, and heard back from IPCC, NASA, and NOAA, the National Oceanic and Atmospheric Administration. What I learned shocked me. For years, the world’s top scientists have known that they cannot prove there has been an acceleration of sea level rise, and yet they have told the public that they can. Not only that, in the process of this exchange, I gained a glimpse into how the scientists have been able to mislead journalists, policymakers, and the wider public for so long. You might think this is either old news or unimportant. Some climate scientists in years past have pointed out that the real-world data do not support claims of acceleration. And in recent years, a supposed increase in natural disasters from climate change has eclipsed sea level rise in terms of attention-grabbing headlines. But sea level rise has, since the 1990s, been the main justification for apocalyptic climate claims, and past efforts to debunk sea level rise have failed to show that scientists were deliberately misleading. The media and others have published terrifying maps of the future showing cities underwater. Accelerated sea level is one of the main justifications for predicting very high costs for adapting to climate change. And while good scientists have debunked acceleration claims in the past, they did not clearly show how IPCC scientists engaged in their manipulations. Not only can I prove that the real-world data do not support the claims that there has been an acceleration, I can show that the scientists deliberately misrepresented their research, and how they did it, thanks to my on-the-record email conversation with Kopp of Rutgers....

Getting a secure roof over your head is life changing. It was heartwarming to listen to a group of new residents who have finally been able to do just that. As part of our Plan for Change, we will build 1.5m homes and increase the number of social and affordable houses.

Why is Antarctica off-limits? The Antarctic Treaty isn’t about “peace”—it’s about hiding the truth. Antarctica isn’t a continent at the bottom of a globe; it’s the 360° ice wall surrounding our flat world, containing Earth’s oceans. We live in the Antarctic basin. Operation Fishbowl, NASA’s lies, and military restrictions all point to one thing: they’re covering up our true reality. Wake up. #FlatEarth #Antarctica #NASADeception

Archaeologist Ed Barnhart breaks down how much we may have underestimated the ancient Amazon, from massive earthworks and geoglyphs hidden beneath the rainforest canopy to man-made black soil, raised causeways, and entire human landscapes still being uncovered. He explains how LiDAR is changing what we know about ancient civilizations in the Americas, why the Amazon may have supported far more people than previously believed, and why future discoveries could completely change our understanding of history. Barnhart also shares why hidden pyramid sites are being found along major rivers in the United States, including the Mississippi, and how much may still be sitting undiscovered on private land and deep in the woods.

Last month, Earth recorded the hottest day EVER in the history of the planet. According to scientists, we have just 5 years left to stop irreversible damage from climate change. For the sake of our children and our planet, we must end our dependence on fossil fuels.

Sea level rise is accelerating due to climate change, threatening coastal communities in the U.S. and around the world. We can still prevent this, but the time to act is running out. That’s why the United States is making historic investments. #UNGA79
