Warming Trends: 2025-2026

The global climate continues to warm at an alarming rate. The years 2023, 2024, and 2025 were the warmest on record, with 2024 being the hottest year ever observed. 2025 was the third warmest year on record, only marginally cooler than 2023. The Met Office forecasts that 2026 will be among the hottest years, continuing a streak that is pushing the planet towards the 1.5°C threshold set by the Paris Agreement. The average global temperature for 2026 is forecast to be between 1.34°C and 1.58°C above pre-industrial levels, with a central estimate of 1.46°C. This means that, for the 13th consecutive year, global temperatures will exceed 1.0°C above pre-industrial levels. This warming trend is driven by the continuous increase in greenhouse gas concentrations in the atmosphere, further exacerbated by natural climate variations, such as El Niño events.

• Record Temperatures: The past 11 years have been the warmest on record.
• Exceeding the 1.5°C Threshold: The three-year average global temperature from 2023 to 2025 has exceeded 1.5°C above the pre-industrial level.
• Continued Warming: The trend shows no signs of slowing down, with 2026 expected to be one of the warmest years on record.

The Direct Impact on Agriculture

Agriculture, the backbone of food production, is directly and severely impacted by global warming. Rising temperatures, altered precipitation patterns, and an increase in extreme weather events are disrupting agricultural practices worldwide. Crops are facing more frequent and severe heatwaves, droughts, and floods, leading to reduced yields and crop failures. Extreme weather events, such as those experienced in the Amazon, can lead to significant crop damage. The crops we depend on are struggling to survive, and the existing approaches to developing tougher, more resilient crops are not moving fast enough.

• Reduced Yields: Heatwaves and droughts cause crop failures.
• Altered Growing Seasons: Changing weather patterns are disrupting traditional planting and harvesting schedules.
• Increased Pest and Disease Outbreaks: Warmer temperatures and altered rainfall patterns favor the spread of pests and diseases.
• Nutrient Decline: Elevated CO2 levels can reduce the nutritional content of staple crops.

Global Warming’s Threat to Food Security

The consequences of these agricultural impacts extend to food security, which is the state of having reliable access to a sufficient quantity of affordable, nutritious food. Global warming threatens this in several ways. Production disruptions lead to local availability limitations and price increases. Interrupted transport conduits can affect the movement of food from production areas to markets. Diminished food safety, caused by extreme weather events and changing environmental conditions, can impact the quality and safety of the food supply.

• Reduced Food Availability: Crop failures lead to lower overall food supplies.
• Increased Food Prices: Reduced supplies and increased demand drive up food costs, making it less accessible for many.
• Nutritional Deficiencies: Changes in crop composition can lead to nutritional gaps.
• Supply Chain Disruptions: Extreme weather can damage infrastructure, hampering food transport and distribution.

Regional Vulnerabilities: Hotspots of Food Insecurity

The impacts of global warming on food security are not uniform; some regions are far more vulnerable than others. Tropical regions and areas heavily reliant on agriculture, particularly those in developing countries, are at the greatest risk. Areas like sub-Saharan Africa and South Asia are particularly exposed due to their dependence on rain-fed agriculture and limited resources to adapt. The USDA report highlights the risks are greatest for the global poor.

• Sub-Saharan Africa: High reliance on rain-fed agriculture makes this region highly vulnerable to droughts.
• South Asia: The melting of Himalayan glaciers threatens water supplies, impacting agriculture.
• Small Island Developing States (SIDS): Sea-level rise and extreme weather events threaten agricultural lands and infrastructure.
• Areas with Existing Food Insecurity: Regions already facing challenges in food access and nutrition are disproportionately affected.

Tipping Points and Irreversible Changes

Global warming is not merely a gradual increase in temperature; it is also pushing the planet towards critical “tipping points.” These are thresholds beyond which changes become self-perpetuating and difficult or impossible to reverse, leading to substantial and widespread impacts. The world is on track to overshoot the Paris Agreement’s 1.5°C target within the next three years, pushing the planet beyond a critical threshold faster than previously feared. This means that by mid-century, a number of tipping points may already have been crossed, ensuring a major transformation of our world from which there is no return.

• Amazon Rainforest Dieback: Transformation from a carbon sink to a source of emissions.
• Collapse of Ocean Currents: Disruption of crucial climate regulators like the Atlantic Meridional Overturning Circulation (AMOC).
• Melting of Polar Ice Sheets: Irreversible sea-level rise and further warming.
• Loss of Coral Reefs: Widespread dieback of coral reefs due to rising ocean temperatures.

Technological Solutions in Agriculture

Fortunately, technological innovation offers several pathways for mitigating the impacts of climate change on agriculture. These technologies can enhance efficiency, build resilience, and reduce emissions. Precision agriculture uses technologies like GPS, sensors, and drones to optimize resource use (water, fertilizers, pesticides) and improve yields. Climate-smart agriculture practices include adopting drought-resistant crops, water-efficient irrigation systems, and conservation tillage. The use of AI and machine learning can analyze vast datasets to predict weather patterns, manage resources, and optimize farming practices.

• Precision Agriculture: Optimizing resource use and increasing yields.
• Drought-Resistant Crops: Developing and using crops that can withstand water scarcity.
• Vertical Farming: Growing crops in vertically stacked layers, minimizing land use and water consumption.
• AI and Machine Learning: Predictive analytics for weather, pest control, and resource management.

Policy and Global Cooperation: The Path Forward

Addressing the climate-related threats to food security requires robust policy interventions and strong global cooperation. The Paris Agreement, now marking its 10th anniversary, remains the central framework for global climate action. It is essential to continue reducing greenhouse gas emissions, transitioning to clean energy, and strengthening adaptation measures. Governments and corporations are pursuing net-zero targets by cutting emissions and scaling carbon removal solutions. Increased financial support for developing countries is crucial to help them adapt to the impacts of climate change and implement climate-resilient agricultural practices. The USDA report highlights that the window for incremental change has closed, and decisive implementation of recommendations is needed to create resilient agricultural systems.

• Strengthening Emission Reduction Targets: Accelerating the transition to clean energy and reducing reliance on fossil fuels.
• Increased Climate Finance: Providing financial and technical support to developing nations.
• Promoting Sustainable Agricultural Practices: Supporting climate-smart agriculture, including agroforestry and conservation tillage.
• International Collaboration: Fostering cooperation on research, technology transfer, and policy development.

Case Study: The Amazon Rainforest and Agricultural Challenges

The Amazon rainforest serves as a stark example of the intricate link between climate change, agriculture, and food security. Deforestation driven by agricultural expansion (primarily for cattle ranching and soy cultivation) is a major driver of greenhouse gas emissions and climate change. The Amazon rainforest is being hit with more days of extreme drought and higher than normal temperatures, leading to tree die-offs that change the nature of these tropical sinks of carbon dioxide. Climate change is increasing the biome’s susceptibility to fire, making it an attractive method for criminals seeking illegal deforestation. The Amazon enters 2026 carrying the bitter taste of compromise, with powerful forces moving to roll back environmental protections. The loss of the Amazon is not only an ecological disaster but also a threat to global climate targets and food security. Experts suggest that the Amazon is already reaching a “tipping point”.

The Role of AI in Climate Adaptation

Artificial intelligence (AI) is emerging as a pivotal tool in climate adaptation and mitigation strategies. In 2026, the application of AI is less about novelty and more about disciplined implementation, improving efficiency in energy systems, strengthening climate-risk management, and accelerating nature-positive outcomes. AI can optimize weather forecasts, satellite imagery, and operational constraints to reduce waste and emissions. AI-driven systems are being deployed to enhance precision agriculture by optimizing resource use and yield prediction. Additionally, AI is helping to predict extreme weather events, assess climate risks, and support early warning systems, enabling more effective emergency response. However, it is important to note that as AI models become more sophisticated, they will accelerate energy and water usage, which underscores the need for energy-conscious engineering.
