Agrivoltaics – combining land for solar and agriculture – is a genuine win-win. It allows a single piece of land to produce both food and clean energy at the same time. Around the world, farmers are finding that solar infrastructure creates microhabitats that boost resilience, improve yields and reduce water stress. For the agriculture: ✅ Shade from the panels lower ground temperatures and reduces evaporation. In arid areas, this has doubled or even tripled crop yields while cutting irrigation needs by half. ✅ Shade-tolerant crops like lettuce, kale, berries and broccoli thrive under reduced heat stress, especially during extreme weather. ✅ Higher soil moisture also promotes healthier pasture, leading to more nutritious forage for grazing animals. For solar operators: ✅ Sheep naturally keep vegetation under control, reducing mowing and maintenance costs and lowering fire risk. They also prevent plants from shading the panels. ✅ Crops underneath the panels help to cool the modules, improving performance on hot days. And the animals benefit too. A 3-year study of 1,700 sheep at the Wellington Solar Farm in NSW found the sheep produced higher quality wool and more of it. The arrays offer shade in summer, shelter during storms and cooler microclimates throughout the day. Economically it's a strong proposition: - Landowners gain a stable income stream while keeping land productive. - Developers access more viable sites with fewer permitting hurdles. - Communities retain agricultural land and benefit from local investment and tax revenue. And in the US, a significant "solar grazing" industry is emerging, where farmers become vegetation managers. They rent out flocks of sheep to solar farm owners and the sheep trim the vegetation. Agrivoltaics is showing that solar and agriculture don’t have to compete for land. They can thrive together – and create more value in the process.

MIT just cleared 50% of Alzheimer's plaques using 40 Hz sound waves. No drugs. No surgery. Just precisely engineered frequencies making immune cells devour toxic proteins. Frequency is becoming medicine's most powerful tool. Think about that. While we've spent decades failing with Alzheimer's drugs, MIT researchers discovered something extraordinary: exposing brains to 40 Hz gamma frequencies activates microglia—the brain's cleanup crew—to clear amyloid plaques naturally. Mice regained memory. Human trials are showing promise. This isn't alternative medicine. It's FDA-approved precision. Traditional Brain Treatment: ↳ Invasive surgery with months of recovery ↳ Drugs that barely slow decline ↳ Blood-brain barrier blocking 98% of medications ↳ Essential tremor requiring skull opening The Frequency Revolution: ↳ 60% tremor reduction in one ultrasound session ↳ Same-day discharge, no incisions ↳ Drug delivery increased 5-fold to brain tumors ↳ 90+ clinical trials transforming neurology But here's what stopped me cold: Focused ultrasound doesn't destroy tissue—it tunes it. Opening the blood-brain barrier for exactly 4 hours to deliver chemotherapy. Synchronizing neurons at 40 Hz to trigger natural healing. Making Parkinson's tremors vanish while patients stay awake, go home that afternoon. We're not attacking disease anymore. We're conducting it away. What changes everything: ↳ Brain surgery without cutting ↳ Alzheimer's clearing without drugs ↳ Tumors targeted without systemic poison ↳ Healing through harmony, not harm The Multiplication Effect: 1 frequency device = surgery avoided 10 hospitals equipped = tremor wards emptying 100 conditions targeted = non-invasive becomes standard At scale = medicine's violent era ends Stanford uses ultrasound for depression. Johns Hopkins for addiction. Mayo Clinic for brain tumors. Each discovering that precisely tuned frequencies can reprogram biology better than any drug. We spent centuries cutting and poisoning disease. Now we're tuning it out of existence. Because when 40 Hz can clear plaques that billion-dollar drugs couldn't touch, and ultrasound can perform brain surgery without a scalpel, we're not just advancing medicine. We're using medical precision. Follow me, Dr. Martha Boeckenfeld for breakthroughs where physics becomes pharmacy. ♻️ Share if you want other to learn about new possibilities to fight Alzheimer.

What happens when companies break their climate promises? Almost nothing. A new study has uncovered troubling truths about corporate climate commitments. Out of 1,041 companies with emissions reduction targets set for 2020: -9% (88 firms) openly failed to meet their goals. -31% (320 firms) stopped reporting on their targets without explanation. What happens when companies miss these targets? Practically no consequences: -Only three failed companies faced media scrutiny. -No significant market backlash, media sentiment shifts, or ESG rating downgrades. In contrast, companies were rewarded with positive press and improved ESG ratings simply for announcing these targets. The bigger issue: This accountability gap threatens the credibility of ambitious 2030 and 2050 climate pledges. Unlike financial targets, which are rigorously monitored, emissions goals often exist in a vacuum—without oversight or real consequences for failure. Interestingly, the study found that: -Firms in common-law countries and those with stronger media accountability had better success rates. -High-emitting sectors like energy and materials struggled the most, with the highest rates of "disappeared" targets. With more companies backing away from climate action, we cannot afford to let this cycle continue. It’s time for corporate sustainability leadership to move beyond announcements and deliver measurable, transparent results. Accountability mechanisms—demanded by both regulators and stakeholders are urgently needed. A great piece of work by Xiaoyan Jiang, Shawn Kim, and Shirley Simiao Lu! Let’s learn from these insights to ensure that corporate climate pledges actually deliver. #climatechange #netzero #esg

A couple of news items have me thinking. And frankly, getting a bit agitated. The first was the news that the Kiwisaver gender gap has got worse in the past year. New research from Te Ara Ahunga Ora The Retirement Commission shows a 36 percent gap between the amount men and women are putting into KiwiSaver each year, far outpacing the actual gender pay gap. Men and women are contributing the same percentage of their salaries, but women are disadvantaged by working part-time and taking greater (unpaid) care responsibilities. The other bit of not-unrelated news, is the NZ Herald’s list of top-earning CEOs. Of the top 10 - just one woman. In the 54 CEOs surveyed: seven women. In the immortal words of Carrie Bradshaw: I couldn’t help but wonder… WTF is going on here? How have we not come further? Of those top 10 CEO’s companies, how many are reporting on their gender pay gaps? (The answer, according to the Mind the Gap registry: 4) Is there a relationship between perimenopause/menopause support (or lack of it) and the lack of women in CEO roles in our top organisations? AND between perimenopause/menopause and the Kiwisaver gender gap? I think there might be. We know, for example, from the work of Sarah Hogan who found in her NZIER research that 14% of women said they had to reduce their working hours to manage their menopause symptoms, and 6% had changed roles. Twenty percent of women who experienced symptoms said it would have been helpful to be able to make adjustments, but they never requested any, mostly because of menopause and gendered ageism stigma. All of us who are working in menopause education have heard stories from women who - at a critical stage in their careers in midlife - have made the call to step back rather than step up into senior roles, because of the challenges of menopause and the lack of support for them in their organisations. We have to talk more about this. In fifty years we’ve made so little progress… we REALLY don’t want our granddaughters to be still facing these kinds of shocking statistics in fifty years’ time. 

Think about the last presentation you sat through. Do you remember anything from it? Probably not. Most presentations fail because they are: ❌ Overloaded with bullet points ❌ Devoid of emotion ❌ Data dumps with no clear story The good news? You can make your presentation unforgettable with these 7 simple shifts: 1. Start with a Hook, Not an Intro Most presenters begin with "I'm excited to be here today..." and lose the audience immediately. Fix: Grab attention from the start. Example: “Your company is losing $10M a year—and you don’t even know why.” 2. Tell a Story, Not Just Data People remember stories, not statistics. Instead of listing facts, wrap them in a compelling narrative. Fix: Use the “Problem → Struggle → Solution” technique. Example: "Before using our system, Sarah’s team spent 3 hours a day on reports. She tried different tools, but nothing worked—until she found our solution. Now? Just 15 minutes a day." 3. Use Contrast & Surprise The brain is wired for novelty. If your presentation sounds predictable, people will tune out. Fix: Vary your tone, pace, and visuals. Drop in an unexpected question, statistic, or pause to keep them engaged. 4. Say Less, Mean More Too much information overloads the audience. They’ll remember nothing. Fix: Cut the fluff. Stick to one core message per slide, per section, per speech. 5. Make It Visual Bullet points don’t inspire. Images and metaphors do. Fix: Instead of saying “Our product is faster,” show a race car next to a bicycle. 6. End with a Bang, Not a Fizzle Most presentations end with “Thank you” and no real impact. Fix: Leave them with one key idea and a clear next step. Example: “If you only take away one thing today, let it be this…” 7. Master the Pause Most speakers talk too fast and leave no room for ideas to sink in. Fix: Silence is power. Pause after key points to let them land. 💡 A great presentation isn’t about information—it’s about transformation. Make your next one impossible to forget.

Extreme heat is becoming the new normal. A new study in Nature Sustainability finds that if global warming reaches 2°C, the number of people exposed to extreme heat will more than double by 2050. 📊 From 1.5 billion people (23%) in 2010 ➡️ to nearly 3.8 billion people (41%) by mid-century. 🔴 The biggest shift happens early, around the 1.5°C threshold. This means adaptation cannot wait for the future. It must happen now. Key implications: 🌍 No part of the world is immune, not even temperate, high-income countries 🏙️ Cities and buildings designed for cold are increasingly unfit for heat ⚡ Energy systems will shift from heating-dominated to cooling-dominated demand 🏥 Health systems, labour productivity, education, and food security are all at risk ❄️ Air conditioning demand is set to overtake heating globally with major equity and emissions implications It is a systems issue, spanning energy, infrastructure, public health, and development. 👉 Early warnings, climate-informed energy planning, heat-resilient buildings, and data-driven adaptation are no longer optional. Because there is no adaptation pathway on a 2°C world that doesn’t involve heat. read the article here https://lnkd.in/eg8pwBMt

A $125B fund to protect tropical forests is gaining traction, reports Justin Catanoso from #COP16. At COP16 in Colombia, an idea as audacious as it is pragmatic took center stage: the Tropical Forest Finance Facility (TFFF), a potentially transformative step in conservation finance. Conceived as a new model for protecting tropical forests, TFFF aims to establish a reliable, results-based income stream for nations stewarding these biodiverse reserves—essentially treating tropical forests as stakeholders in our planet’s future. Despite a patchwork of conservation funds, financing has simply not kept pace with the rapid rate of forest loss. Enter the TFFF, structured to attract up to $125 billion from a mix of sovereign investors, philanthropies, and private sources. Its ambition is to reward countries for slowing deforestation and safeguarding tropical forests, offering an annual return of $4 billion, contingent upon rigorous satellite monitoring and adherence to conservation targets. While other funds have relied on goodwill and grants, TFFF introduces a model akin to a bond fund, rewarding investors while incentivizing nations to keep forests intact. The initiative’s architects envision a diversified portfolio, combining climate-friendly investments—such as green bonds in developing economies—with fixed-income securities in more established markets, aiming for stable returns to underwrite ambitious payouts. Penalties for deforestation are stringent: each hectare lost forfeits the equivalent of rewards for 100 hectares. Such measures aim to maintain a steady yield over an anticipated 20-year lifecycle, supporting more than 70 tropical nations in preserving, rather than depleting, their natural capital. Beyond its environmental goals, TFFF’s structure addresses the governance and transparency challenges often faced by global finance initiatives. A globally recognized body would oversee fund administration, minimizing political influence and ensuring that proceeds are distributed equitably and transparently. Payments will be tracked and verified, supported by an annual “Global Score Card” to enhance public accountability. If successful, TFFF could represent a shift from traditional conservation financing, creating an asset-backed approach where nature's essential services are finally valued. Tropical forests—indispensable for climate stability, biodiversity, and local livelihoods—have long been absent from balance sheets. As TFFF’s supporters might say, it’s high time forests were valued for their productivity as ecosystems, not just as raw materials. 📰 Catanoso's story: https://lnkd.in/gfmdvyPm Photos: various rainforests I've photographed.

🔥 Climate risks are no longer abstract—they’re disrupting businesses, communities, and economies right now. The World Economic Forum’s 2024 report, "The Cost of Inaction: A CEO Guide to Navigating Climate Risk", delivers a sobering message: ignoring climate risks isn’t just irresponsible—it’s economically devastating. 🌡️ Key insights from the report: 💥 Climate-related disasters have caused $3.6 trillion in damages since 2000, exposing critical vulnerabilities in supply chains and infrastructure. 📉 Physical risks could put 5-25% of EBITDA at risk for some sectors by 2050 under a 3°C warming trajectory. 💸 Transition risks, like carbon pricing and changing regulations, could impact 50% of EBITDA in energy-intensive industries by 2030. 🌱 Every $1 invested in climate adaptation yields $2-$19 in avoided costs, while green markets are projected to grow from $5 trillion in 2024 to $14 trillion by 2030. 💡 My reflections: 🔄 Resilience isn’t enough anymore. Too often, we focus on simply "weathering the storm" of climate risk. But true leadership is about rebuilding something better—rethinking markets, redesigning business models, and creating solutions that lead entire industries forward. 🌍 Supply chain fragility is the Achilles’ heel of the global economy. A single extreme weather event can cascade across operations, grinding everything to a halt. Climate-resilient supply chains can’t just be about survival—they must be radically adaptive, decentralized, and built to thrive under disruption. 📊 Climate risk is fundamentally redefining the concept of value. Businesses stuck chasing quarterly earnings are missing the bigger picture. In a world of rising costs and irreversible climate impacts, long-term value will belong to those who embed sustainability, resilience, and equity into their strategies. The time for cautious, incremental steps has passed. How are we using this moment to transform the way we work, innovate, and lead? #ClimateAction #Sustainability #Resilience #Leadership #Innovation

We’ve called efficiency the unsung hero of the energy transition in the past. While the energy transition will happen first through the transition of energy usages, like the shift with transport, from internal combustion engines to electric vehicles, or from fuel or gas boilers to heat pumps, we cannot ignore the utmost priority of the energy transition: efficiency. Efficiency is the greatest path to reduce our energy use, our impact on the world’s climate through CO2 emission reduction, and very importantly, the best way to make solid and practical savings. In its most historical form, energy efficiency is about better insulation, to reduce heating (or cooling) loss in buildings like family homes, warehouses, office high rises, and shopping malls. This is useful, but expensive and tedious to realize on existing installations. Digitizing home, buildings, industries and infrastructure brings similar benefits at a much lower cost and a much higher economic return. The combination of IoT, big data, software and AI can significantly reduce energy use and waste by detecting leaky valves, or automatically adjusting heating, lighting, processes and other systems to the number of people present at any given time, using real-time data analysis. It also allows owners to measure precisely progress, report automatically on their energy and sustainability parameters, and benefit from new services through smart grid interaction. And this is just the energy benefit. Automation and digital tools also optimize the processes, safety, reliability, and uptime leading to greater productivity and performance.
