The food system must contribute to maintaining the 1.5-degree target set by scientists based on physics, mathematics, biology, and chemistry. The consequences of climate change are already evident and surpassing predictions made over the past 30 years.

Sea ice in the Arctic is melting rapidly, leading to the exposure of the Arctic Ocean. Scientists estimate that within the next five years, we will witness the first ice-free Arctic summer.

In 2023, global temperatures hit record highs, leading to extreme weather events worldwide. Heat waves occurred globally, even in South America during winter. Wildfires in Canada burned an area nearly 5 times the size of Switzerland. Record floods, including in Libya, caused significant damage and loss of life. A flood in New York resulted in water bursting from subway walls. Droughts affected South America and the Horn of Africa. These events highlight the impact of climate change, referred to as "global weirding" due to the noticeable changes in weather patterns experienced by people worldwide.

There is an old joke that goes God created war so that Americans would learn geography. In 2026, they seem to be learning it the hard way. They’ve discovered that 10,900 kilometers from Washington DC lies the Strait of Hormuz, the world’s most critical choke point, a narrow strip of water between the Persian Gulf and the Gulf of Oman that stretches 167 kilometers in length, narrows to just 34 kilometers at its tightest point, and carries roughly 30,000 vessels a year. Around a fifth of the world’s traded oil and LNG flows through this corridor on normal days. Most of that oil heads to Asia, but oil prices don’t respect geography. They’re set globally. So when West Asia sneezes, fuel prices spike everywhere. Oil is only the start. Over 30% of global ammonia trade, nearly half of urea, and 20% of diammonium phosphate, key fertilizer inputs, move through this same choke point, along with about half the world’s sulfur for metal processing. If the sulfur didn’t arrive, the factory was shut down. It didn’t arrive because of the war and because the Strait of Hormuz was closed. Unlike oil, these can’t be rerouted. There are no pipelines for ammonia or urea. If Hormuz closes, the nitrogen supply chain doesn’t slow. It stops. And since synthetic nitrogen fertilizers support roughly 48% of the global population, missing the mid April application window in the Northern Hemisphere means lower yields by September. Major importers like India, Brazil, Pakistan, Bangladesh, and many African countries would quickly face fertilizer shortages, leading to higher food prices, inflation, and a widespread food security crisis affecting billions. 85% of Brazil’s fertilizer is imported. And under these conditions, we can only bring part of the land under cultivation. Meanwhile, about a third of the world’s helium, critical for semiconductors and MRIs, passes through these strait. So does nearly 10% of global aluminum and a significant share of Persian Gulf produced plastics. Even the Persian Gulf states themselves are exposed. This passage is their food lifeline. The biggest one, Saudi Arabia, imports over 80% of its food. The smallest one, Qatar, 85%. If the strait stays closed for another month or two, the food situation here is gonna get really critical. If anyone thinks the so called first world would be immune, the reality says otherwise. Since the war began, Brent crude has swung from $73 to nearly $120 at one point, adding about €500,000,000 per day in EU energy costs. In late April, the IEA warned Europe may have only six weeks of jet fuel left as West Asian imports falter. Prices have surged past $1,500 per ton. The IEA calls this “the greatest energy crisis in history.” By April 22, Lufthansa had canceled 20,000 flights with more disruptions and price hikes expected. In Germany, the industrial heart of Europe, 78.6% of firms report uncertainty about their future, rising to 87.7% in manufacturing and over 90% in chemicals, rubber, and plastics. The US isn’t insulated either. Gas prices jumped more than $1 per gallon in just six weeks, surpassing $4.10, the highest level since 2022, while the Hormuz shock fuels inflation. They said the consumer price index rose 0.9% in March, almost 1% in just one month. I haven’t seen a jump like that in years. Meanwhile, a Reuters/Ipsos poll put Trump’s approval rating at 36%, its lowest since his return to office. Forty-eight hours into the Iran war, marine insurers began canceling war risk coverage in the Persian Gulf. By March 5, commercial insurance had effectively vanished. No insurance means no shipping. No shipping means no trade. This isn’t a new insight. Back in 1507, Portuguese admiral Alfonso de Albuquerque understood that Whoever controls this choke point controls the flow between India and the Mediterranean. And by extension, global trade itself. So far, the largest empire in history finds itself with remarkably little to say against one of the oldest. Perhaps this time, the Americans picked the wrong country to learn geography.

Agriculture is responsible for about 33% of global emissions, which could rise to 26-33%. To achieve net zero, agriculture must be a key part of the solution. With a growing population of over 8 billion, emissions from the food system alone could cause an additional 0.5 degree of warming by mid-century. A two-degree future could lead to 600 million people facing food shortages. We cannot warm the planet and expect to feed it. To maintain a 1.5-degree limit, we must reduce emissions from the food system. Scientists, based on physics, mathematics, biology, and chemistry, have warned us about the consequences, which are already happening faster and bigger than predicted.

Women and girls, especially in the global south, bear the brunt of climate change. Extreme heat poses a significant challenge, particularly for women working in the informal economy. Their jobs in fields, factories, and markets become impossible in temperatures of 40-50 degrees Celsius. The number of deaths related to climate change is alarming, with Europe alone recording 61,000 deaths due to heat last summer. Unfortunately, we don't have precise figures for Africa, Asia, and Latin America yet, but estimates suggest that out of 500,000 deaths, the majority are women and girls. Pregnant women face additional challenges in extreme heat.

The melting of Greenland's ice sheet could raise sea levels by 7 meters.

In 5 years, scientists predict the first ice-free Arctic summer. This will expose more ocean to sunlight. Because the ocean is dark, it will consume more heat from the sunlight. This accelerates melting and warming, as opposed to the ice and snow which used to reflect sunlight back into the atmosphere.

Agriculture contributes 26-33% of global emissions, making it central to achieving net zero. The world population recently surpassed 8 billion, increasing the urgency. Food system emissions alone could cause an additional 0.5 degrees of warming by mid-century. A 2-degree warming scenario could leave 600 million more people undernourished. Reducing food system emissions is crucial to keeping the 1.5-degree target alive. Scientists using physics, mathematics, biology, and chemistry have warned of consequences already being observed. These consequences are materializing faster and with greater intensity than initially predicted.

Emily Speck reports that nearly 700 sinkholes are tearing open Turkey's farmland, with the Koinya Plain—the region that grows much of Turkey's wheat—literally caving in. Close to 684 large sinkholes have been found across the Koinya Plain, and new ones are appearing every year. Scientists point to a dangerous combination of extreme drought, climate change, and decades of heavy groundwater pumping as drivers of the collapses. In the Karapanar district alone, more than 20 new sinkholes opened in the past year, some stretching as wide as 100 feet across and plunging hundreds of feet down. Researchers say the collapses have accelerated since the early 2000s, putting farms, livestock, and entire rural communities at risk. The situation is compounded by reservoirs dropping to their lowest levels in fifteen years, which experts say may cause the ground beneath Koina to continue giving way. The widening network of sinkholes threatens agricultural productivity and local livelihoods, as large swaths of arable land become unstable or unusable. The ongoing subsidence not only disrupts crop cycles but also endangers irrigation infrastructure and roads that connect communities within the plain. Experts emphasize that the phenomenon is not isolated to a single location but reflects a broader pattern across the region as groundwater extraction remains intensive and climate variability intensifies. The intersection of drought conditions, shifting precipitation patterns, and sustained pumping is linked to the emergence of more sinkholes, according to the reporting. With the region’s breadbasket status at stake, there are concerns about long-term impacts on food supply and regional economies dependent on farming and related services. As the ground continues to respond to environmental pressures and human water use, authorities and researchers are likely to monitor groundwater levels, land stability, and reservoir accounts closely. They may seek to balance agricultural needs with measures to reduce vulnerability to subsidence, while communicating ongoing developments to residents who inhabit communities within the affected areas. For AccuWeather, this is Emily Speck.

Scientists predict that within five years, we will experience the first ice-free Arctic summer. This will expose the dark ocean to more sunlight. The ocean absorbs more heat from the sunlight, accelerating melting and warming. This is because the ice and snow, which used to reflect sunlight back into the atmosphere, will be gone.

Agriculture is responsible for a significant portion of global emissions, ranging from 26% to 33%. To achieve net zero emissions, agriculture must be a central part of the solution. However, with a growing population of over 8 billion people, emissions from the food system alone are projected to cause half a degree of warming by mid-century. This could result in 600 million people not having enough food in a two-degree future. We cannot warm the planet and expect to feed it simultaneously. To maintain a 1.5-degree limit, we must reduce emissions from the food system. Scientists, based on physics, mathematics, biology, and chemistry, have warned us about the consequences of exceeding this limit, which are already becoming evident and surpassing previous predictions.

Achieving net zero emissions would lead to widespread hunger and disease as 50% of the population relies on nitrogen fertilizer for survival. Attempts to ban nitrogen fertilizer in countries like the Netherlands and Sri Lanka are seen as a misguided effort to save the earth, which does not necessarily need saving.

Their predictions have been coming true faster and on a larger scale than anticipated.

Scientists' warnings about mega storms, floods, droughts, ice melting, rising sea levels, stronger storms, tropical diseases, and climate migrants have been accurate. Without action, there could be 1 billion climate refugees crossing international borders in the coming decades. A few million refugees have already contributed to a wave of populist authoritarianism, and a billion could overwhelm our capacity for self-governance. People are already being displaced from their homes, and areas are becoming physiologically unlivable due to heat and humidity. These areas, currently small, could expand to include most of India, large parts of Northern South America, the Philippines, Indonesia, and Pakistan if no action is taken. The survival of our civilization is at stake.

Scientists claim the Earth's atmospheric temperature has been rising over the past 100 years, Antarctic ice sheets are melting faster, and sea levels have been rising more swiftly over the past 40 years. If correct, about 25% of Florida could be flooded in the next century, along with other low-lying areas. Climate changes could disrupt agriculture, potentially making the American farm belt too dry and shifting wheat and corn crops to Canada. Scientists attribute these changes to carbon dioxide gas, which creates a greenhouse effect by trapping heat and preventing it from rising into space. They maintain that burning coal, oil, and gas for a century has increased carbon dioxide levels, overheating the Earth. Some express concern that sufficient research isn't being conducted to determine the accuracy of these alarming assessments. Scientists are using computer models to predict the melting rate of Arctic ice and its impact on ocean levels, which could affect millions and the survival of cities.

Einar Tangin and Glenn discuss the forthcoming Xi Jinping–Donald Trump meeting and the broader strategic landscape shaping U.S.–China competition. - On the Trump–Xi meeting: Tangin expects very little substantive outcome. China’s strategy toward the United States is to keep engagement open rather than push Trump into a corner, despite Trump’s past actions and their consequences. He notes a narrow scope to be discussed in a California meeting, with Trump volunteers unprepared and pushing “the usual maximist stuff.” China is signaling that Taiwan will be a red line. Beyond that, the Chinese may accept limited concessions such as grain, gas, or oil purchases, but no sweeping arrangements. The overall takeaway: continued engagement, but not a game-changing breakthrough. - U.S. energy and global strategy: Tangin argues the United States uses energy as a tool of influence, aiming to control access and shape markets (the petrodollar legacy, strategic chokepoints). The Ukraine war has accelerated Europe’s decoupling from Russia and the U.S. seeks to expand similar dynamics in East Asia. He emphasizes that the energy game is dynamic: oil prices impact inflation, and long-term, demand destruction and a shift to alternatives (electricity, renewables) will reshape markets. He points to new energy tech and scale: batteries and storage (CATL’s battery capacity) enable large-scale decoupling from fossil fuels; China’s plans to deploy up to 50 nuclear plants at a time and to pursue commercially available fusion power could transform the energy landscape. The U.S. may face higher exploration costs and geopolitical risk in sustaining high oil output, while heavy reliance on fossil fuels could erode long-term economic viability. - Global consequences and who bears the pain: In the short term, countries without reserves (notably parts of the Global South, including India) will face fertilizer and diesel shortages during planting seasons, with potential 15–25% yield reductions and elevated inflation. Food security risks loom as energy costs ripple through fertilizer, transport, processing, and farming inputs. The analysis highlights fertilizer nitrogen production’s energy intensity and the cascading nature of energy in food supply chains. The discussion stresses that global south economies will be hit hardest early on, with food and fuel inflation compounding social and political pressure. - The Iran war and maritime strategy: The discussion connects the Persian Gulf crisis to broader blockades and maritime competition. A naval blockade approach risks escalation and confrontation with China, which has extensive trade links through ASEAN and other partners that would be harmed by disruption. Tangin notes that China cannot be easily forced into combat in Europe or the Middle East; any escalation involving tactical nuclear use would be dangerous. He suggests that Europe’s elites may push for confrontation against Russia, but the political climate and energy constraints could destabilize Western allies and push towards alternative alignments, particularly with China. - China’s strategic posture and alternative world order: Tangin emphasizes that China has a model that emphasizes no ideology between states, sovereignty, and mutual non-interference, echoing a Westphalian framework. He describes China’s global governance concept as a peer-to-peer, negotiation-centered approach, where disputes are settled at the table rather than through force. He frames China’s proposition as simple: “No more ideology between countries. Every country should be secure. Security should not depend on the insecurity of another country. Every country has the right to choose its own path of development.” This is presented as a peaceful, governance-based alternative to U.S.-led hegemony. - Europe’s strategic crossroads and the future: Europe faces existential economic strains, competitiveness challenges, and the temptation of isolationist or right-wing governance. The conversation predicts prolonged political volatility if energy prices and inflation persist, with potential swings between different leaderships. China’s strategy, in this vision, is to promote internal diversification and consumption-led growth while engaging with international partners on a governance framework that reduces the incentives for confrontation. - Concluding note: The speakers agree that Europe’s willingness to embrace China’s model, rather than clinging to a confrontational U.S.-led paradigm, could shape a more stable global order. They caution that the old order has ended, and creative destruction is underway, with China advocating a negotiated, governance-based path forward.

Climate dynamics are presented as a cause-and-effect sequence tied to ocean circulation. As the AMOC slows, the Northern Hemisphere cools. That cooling shifts the tropical rain band south, and the monsoons effectively miss regions that count on them for up to 90% of their yearly precipitation, directly impacting food security for over 2,000,000,000 people. The overall message is a chain reaction from circulation changes to rainfall distribution and human outcomes. In summary, the slowdown of the AMOC is linked to hemispheric cooling, to shifts in tropical rainfall patterns, to disrupted monsoons affecting precipitation, and to implications for food security. These points describe a sequence of interconnected shifts.

Scientists claim the Earth's atmospheric temperature has been rising over the past 100 years, Antarctic ice is melting faster, and sea levels have risen swiftly in the last 40 years. If correct, 25% of Florida could flood, along with other low-lying areas globally, and agriculture could be widely disrupted, potentially moving the American farm belt to Canada. These changes are blamed on carbon dioxide, which traps heat like a greenhouse. Scientists maintain that burning coal, oil, and gas for a century has increased carbon dioxide, overheating the Earth. Some political leaders support more carbon dioxide monitoring stations and share scientists' anger over Reagan administration budget cuts, hindering research to determine the accuracy of these alarming assessments. The findings could affect millions and the survival of cities.

Agriculture is responsible for a significant portion of global emissions, ranging from 26% to 33%. To achieve net zero emissions, agriculture must play a central role in the solution. However, with a growing population of over 8 billion people, emissions from the food system alone are projected to cause half a degree of warming by midcentury. This could result in 600 million people facing food insecurity in a 2-degree future. To prevent this, we need to reduce emissions from the food system and strive to keep global warming within 1.5 degrees. Scientists have warned us about the consequences of exceeding this limit based on physics, mathematics, biology, and chemistry. These predictions are already coming true, but at a faster and larger scale than anticipated.

Speaker 1 argues that the outcome mentioned in the headline is already baked in due to the lack of energy and fertilizer coming out of the Strait of Hormuz. He notes we are in week nine of the conflict, and there doesn’t appear to be a solution in sight. If the conflict lasts a few more months, it becomes catastrophic on a global scale. The countries most impacted will not be the United States but nations that already have tens of millions on the edge of famine, including Sudan and Yemen. Egypt is close to that category, and India and Bangladesh will also have a lot of difficulty. He explains that Bangladesh has its own nitrogen production plants but relies on imported natural gas to produce nitrogen. Two of Qatar Energy’s 14 natural gas trains, which are production pipelines, are out of commission for three to five years, taking 17% of Qatar Energy’s gas offline. The Haber-Bosch chemical process, which turns gas into ammonia and then into urea and other nitrogenous fertilizers, underpins this. Therefore, the world is already going to face starvation of millions in 2027, and that number could grow to tens of millions or even hundreds of millions if the Strait of Hormuz is not open soon. Speaker 0 asks for a global explanation of how the food system works and why countries depend on inputs from abroad. Speaker 1 responds that about 8,000,000,000 people globally, or roughly 4,000,000,000 or more, live today because of the Haber-Bosch process that turns hydrocarbons into ammonia and then nitrogenous fertilizers. If the supply chain is lost, and while not all natural gas comes from the Strait of Hormuz, a large amount—25% or more—comes from there for fertilizer production. The destruction of Nord Stream pipelines affected BASF (BASF is a German company) which produced nitrogenous fertilizers from Russian gas, and that cut off years ago. China and Russia have now halted all exports of fertilizers, including to India, which asked China for emergency fertilizer and was told that China needs it for its own populations. The bottom line is that not only is the natural gas feedstock being cut off that would normally feed 4,000,000,000 of the 8,000,000,000 on the planet, but countries are becoming more nationalized with their supplies, leaving vulnerable countries like Bangladesh, Thailand, and India hanging in the wind.

Agriculture is responsible for about 33% of global emissions, which could increase to 26-33%. To achieve net zero, agriculture must be a key part of the solution. However, with a growing population of over 8 billion people, emissions from the food system alone could cause half a degree of warming by mid-century. This could result in 600 million people not having enough food in a two-degree future. We cannot warm the planet and expect to feed it simultaneously. To maintain a 1.5-degree limit, we must reduce emissions from the food system. Scientists have warned us about the consequences based on physics, mathematics, biology, and chemistry, and these predictions are already coming true, but at a faster and larger scale than anticipated.

The goal of limiting global warming to 1.5 degrees Celsius is crucial, as even a small increase can have significant impacts. The Paris Agreement, signed by 193 parties in 2015, aims to keep temperature rise below this threshold. Currently, the planet is already 1.1 degrees warmer than pre-industrial levels. If temperatures rise by 1.5 degrees, 69 million people will be affected by rising sea levels, while 80 million will be affected at 2 degrees. Heat waves will impact 14% of the population at 1.5 degrees, increasing to 37% at 2 degrees. Additionally, biodiversity loss and extreme weather events will worsen. To achieve the 1.5-degree target, global emissions must be reduced by 45% by 2030 and reach zero by 2050. Immediate action is essential to minimize the worst effects of climate change.
