Did you know that the apples you enjoy might soon face serious challenges because of rising temperatures?

Apples, one of the most beloved and healthiest snacks, are under threat. As climate change reshapes weather patterns, it’s also impacting how—and where—our food grows. These changes affect not just apples but many of the healthy foods we rely on every day. Understanding this issue is crucial for anyone who cares about their health and the environment. Let’s dive into how climate change is affecting your food.

The Science Behind the Problem

How Climate Change Impacts Agriculture

Climate change is causing shifts in temperatures, rainfall, and weather patterns worldwide. For agriculture, this means disrupted growing cycles, extreme heat, and unpredictable frosts—all of which create challenges for crops. Perennial crops like apples are particularly vulnerable because their growth depends on consistent weather conditions year-round.

Apples as a Case Study

Apples provide a clear example of how climate change affects food production. Scientists have identified six key climate factors that influence apple growth, including:

  • Extreme Heat Days: Days when temperatures exceed 93°F can cause sunburn on apple skins, reducing their quality.

  • Warm Nights: Nighttime temperatures above 59°F can prevent apples from developing their rich red color, making them less appealing to consumers.

  • Reduced Chill Portions: Apples need cold periods during winter to rest and prepare for spring growth. Warmer winters mean fewer of these essential chill hours.

  • Earlier Frost-Free Days: While this might sound good, it can disrupt the natural bloom cycle, increasing the risk of frost damage later.

Yakima County in Washington, one of the leading apple-producing regions in the U.S., has seen harmful trends in five of these six metrics. These changes reduce apple yield, size, color, and taste—qualities that make apples a staple in healthy diets.

Why It Matters to You

Health Implications

Changes in food production can directly impact your diet. When apples face extreme heat or warm nights, they may lose their flavor and nutritional value. Reduced availability of high-quality apples could make healthy eating more expensive or harder to achieve.

Environmental Concerns

When crops like apples struggle, farmers must use more resources to maintain production. This includes water for cooling trees during heatwaves or energy to run protective equipment. These added measures can increase the carbon footprint of growing food, contributing further to climate change—a cycle that’s tough to break.

Actions Being Taken

Adaptation by Farmers

Farmers are already finding ways to adapt. Here are some strategies being used:

  • Netting: Covers are placed over apple orchards to protect fruit from sunburn.

  • Evaporative Cooling: Spraying water on trees helps lower their temperature during heatwaves.

  • Crop Diversification: Planting heat-resistant apple varieties or other crops reduces risk.

Scientific Research and Innovation

Researchers are also stepping in. A $6.75 million USDA-funded project is helping farmers mitigate extreme climate events. This initiative includes studying how to adapt apples and pears to new growing conditions across the U.S., starting with Washington State. Scientists are working to find long-term solutions that keep crops productive despite challenging conditions.

How You Can Help

  • Support Sustainable Practices: When you buy apples and other produce, look for labels that indicate sustainable farming practices. Supporting local farmers who prioritize environmentally friendly methods can make a big difference.

  • Reduce Food Waste: Every piece of wasted food represents water, energy, and labor lost. By planning meals carefully and storing apples properly, you can reduce waste and lessen the strain on farmers already coping with climate challenges.

  • Advocate for Change: You don’t have to be a farmer to make a difference. Get involved in climate-friendly initiatives or share this information with others. Raising awareness about how climate change affects food can inspire collective action and support for sustainable practices.

Summing Up

Climate change is reshaping how and where our food is grown, with apples as just one example of a crop under threat. The impacts go beyond the farm, influencing your health, your wallet, and the environment. But there’s hope—farmers, scientists, and consumers can work together to protect our environment and food supply.

How Melting Ice Shapes Our Climate, Water, and Future—and What We Can Do to Protect It

Did you know that Greenland is losing 30 million tons of ice every hour? This isn’t just a shocking statistic—it’s a wake-up call. The melting of the world’s ice isn’t just a problem for cold regions; it’s an issue that impacts all of us, from the water we drink to the air we breathe. This week we examine the importance of Earth’s ice, the alarming changes it’s undergoing, and why it matters to your life.

The Big Picture: What Is the Cryosphere?

The “Cryosphere” might sound like a complicated word, but it simply means all the parts of Earth covered in snow and ice. This includes glaciers, ice sheets, permafrost (frozen ground), and sea ice.

Why does the cryosphere matter?

  • Temperature Regulation: The cryosphere reflects sunlight, keeping the planet cool, much like a natural air conditioner.

  • Water Storage: It stores about 70% of the world’s fresh water, feeding rivers and supporting billions of people.

Without the Cryosphere, Earth would be hotter, drier, and much less hospitable.

Alarming Changes in Ice and Snow

The Cryosphere is changing fast, and the consequences are already being felt worldwide. Greenland is losing ice at an unprecedented rate, enough to raise sea levels significantly in the coming decades. Glaciers in the Alps and Himalayas are melting at record levels, threatening water supplies for millions of people downstream.

In addition, Antarctic sea ice is shrinking, with three consecutive years of record lows. This destabilizes the Antarctic ice sheet, which could lead to catastrophic sea-level rise. And, frozen ground in Arctic regions is thawing, releasing harmful greenhouse gases like carbon dioxide and methane. This accelerates global warming and damages infrastructure in those regions.

Why It Matters to You

Melting ice may seem like a distant problem, but its effects are closer to home than you think.

  • Rising Seas: As ice melts, sea levels rise, threatening coastal cities and communities. Major cities like New York, Miami, and Mumbai face increased flooding risks.

  • Water Supply: Snow and ice act as reservoirs, releasing water during warmer months. With less snowpack, regions like the Himalayas and Andes face water shortages, impacting agriculture and drinking supplies for billions.

  • Changing Weather: Melting ice disrupts weather patterns, leading to stronger storms, unpredictable rainfall, and even impacts on fisheries as oceans warm and acidify.

The Path Ahead: What Scientists Say

The Cost of Inaction

If emissions continue at current levels, global temperatures could rise by 3°C or more by the end of this century. This would push many regions beyond their ability to adapt, leading to economic and human costs that are unimaginable.

Hope Through Action

The good news? Scientists agree that if we act now to limit warming to 1.5°C, we can slow ice loss and reduce long-term damage. This requires cutting emissions by 50% by 2030 and reaching net-zero by 2050.

What Can Be Done?

Global Solutions

To address the challenges posed by melting ice and its global impacts, reducing emissions is a critical step. Transitioning to renewable energy sources like wind and solar can significantly cut greenhouse gas emissions, slowing the pace of global warming and ice loss. Additionally, protecting vulnerable areas is essential. Investing in resilient infrastructure and implementing policies designed to safeguard communities can help mitigate the risks of rising seas and water shortages, ensuring these regions are better prepared for the future.

Individual Steps

You don’t have to be a scientist or policymaker to make a difference. Here’s how you can help:

  • Advocate for climate-friendly policies in your community.

  • Use public transport, conserve energy, and support sustainable products.

  • Spread awareness by sharing what you’ve learned with friends and family.

Summing Up

Saving the world’s ice isn’t just about preserving glaciers—it’s about protecting our homes, food, and future. The actions we take today will shape the world for ourselves as well as future generations. Each degree of warming we prevent reduces the risks to our planet and ourselves. Let’s work together to ensure that ice continues to cool the Earth, sustain life, and inspire hope for a better tomorrow.

A Call to Action

The health of our planet and our children are closely linked. Biodiversity—the variety of life on Earth—plays a critical role in keeping ecosystems and people healthy. Yet, biodiversity is rapidly declining, and climate change is worsening its impacts. Children are particularly vulnerable to these changes, as their developing bodies are more sensitive to environmental stressors and they face a longer lifetime of exposure.

Understanding the Crisis

What Is Biodiversity and Why Does It Matter?

Biodiversity refers to the variety of plants, animals, and microorganisms on Earth, as well as the ecosystems they form. It ensures clean air, water, and food, regulates diseases, and supports human health in countless ways.

However, human activity—deforestation, pollution, and overuse of natural resources—has caused biodiversity to decline at an alarming rate. Combined with climate change, these losses create a cycle of destruction that threatens not just the environment, but also our health.

Why Are Children More Vulnerable?

The impacts of biodiversity loss and climate change are particularly severe for children due to their unique vulnerabilities. These include biological factors and social dependencies that make them less able to cope with environmental changes. For example:

  • Their immune, respiratory, and nervous systems are still developing.

  • They breathe more air and consume more food relative to their size, increasing exposure to pollutants.

  • They depend on adults to provide safe environments and resources.

Key Areas of Impact on Pediatric Health

Microbial Diversity: Building Immunity

Microbial diversity, found in soil, water, and plants, is essential for the healthy development of a child’s immune system. When ecosystems lose biodiversity, children lose exposure to beneficial microbes, leading to a range of health issues.

  • What It Does: Microbial diversity in soil, water, and plants influences the microbes children are exposed to, which is essential for developing strong immune systems.

  • The Problem: Biodiversity loss reduces exposure to beneficial microbes, increasing risks of allergies, asthma, and inflammatory diseases.

Green Spaces: Nature’s Healing Power

Green spaces with diverse plant and animal life provide much more than aesthetic beauty. They are critical for children’s mental, emotional, and physical health, offering restorative environments for growth and learning.

  • Benefits: Access to biodiverse green spaces improves physical activity, mental health, and cognitive development in children.

  • Evidence: Studies show that exposure to diverse plant and animal life in parks and gardens boosts children’s emotional well-being and attention spans.

Heatwaves and Flooding: Rising Risks

As climate change drives more extreme weather, children are facing increasing risks from heatwaves and flooding. These events not only cause immediate health threats but also disrupt the ecosystems that help protect against them.

  • Heat-Related Illnesses: Children are at greater risk of heat exhaustion and dehydration during heatwaves, which are becoming more frequent due to climate change.

  • Flooding: Loss of ecosystems like wetlands, which absorb excess water, increases the risks of displacement, injury, and waterborne diseases.

Infectious Diseases: Expanding Threats

Climate change is enabling the spread of disease-carrying insects to new regions, putting children at a greater risk of infectious diseases. Biodiversity loss compounds this by reducing natural pest control systems.

  • Vector-Borne Diseases: Climate change allows disease-carrying insects like mosquitoes to thrive in new regions, increasing risks of illnesses like dengue and Lyme disease.

  • Children at Risk: With weaker immune systems, children are more susceptible to severe outcomes.

Air Pollution: Breathing Problems

The destruction of biodiversity-rich ecosystems contributes to worsening air pollution. For children, this means a higher risk of respiratory illnesses and developmental challenges.

  • The Link: Biodiversity loss contributes to air pollution as ecosystems that filter air—like forests—are destroyed.

  • Impact: Air pollution worsens asthma, bronchitis, and developmental issues in children.

Pediatric Medicine: Lost Potential

Biodiversity plays a key role in medical advancements. Many life-saving medicines have been discovered through the study of plants, animals, and microorganisms, a potential that is at risk with biodiversity loss.

  • Biodiversity’s Role: Many medicines are derived from plants, animals, and microorganisms. For example, antibiotics like penicillin come from fungi.

  • The Risk: Biodiversity loss could mean less availability of these medicinal sources.

Solutions and Mitigation Strategies

Ecosystem Restoration

Restoring biodiversity is critical for mitigating the impacts of climate change and creating healthier environments for children. These efforts can range from local projects like community gardens to global initiatives aimed at protecting ecosystems.

  • What Works: Rewilding efforts and urban planning that integrate biodiversity can restore ecosystems and improve air quality, reduce flooding, and create cooling effects.

  • Example: Restored urban green spaces have been shown to lower temperatures and improve local health outcomes.

Engaging Children in Biodiversity Initiatives

Getting children involved in biodiversity restoration not only helps ecosystems but also benefits their mental health and emotional well-being. These programs foster a sense of agency and environmental awareness.

  • Programs: Community gardens, tree-planting drives, and biodiversity education in schools.

  • Benefits: These activities not only improve ecosystems but also enhance children’s mental health, provide hands-on learning, and empower them to take action.

Policy and Community Action

Addressing biodiversity loss requires a collaborative effort across individuals, communities, and governments. Policymakers and organizations can create programs that protect and restore biodiversity while involving the public.

  • Global Initiatives: The UN Decade on Ecosystem Restoration is an example of efforts to promote biodiversity worldwide.

  • Local Efforts: Schools and communities can push for greener policies, like protecting wetlands or creating more biodiverse parks.

Research Gaps and Future Directions

While we know biodiversity loss and climate change harm children’s health, more research is needed to fully understand the long-term effects. By addressing these gaps, we can create better solutions tailored to children’s needs.

  • More studies are needed on the long-term health benefits of biodiversity restoration.

  • Research should focus on how interventions, especially in underserved communities, can best support children.

Summing Up

Biodiversity and climate change are not abstract issues—they directly impact children’s health today and their futures tomorrow. From the air they breathe to the spaces they play in, children are deeply connected to the natural world. Protecting biodiversity results in safeguarding the well-being of the next generation.

Call to Action

We can restore biodiversity by planting native species, reducing waste, and supporting conservation organizations. Communities can demand greener policies, and governments must prioritize ecosystem restoration. Together, we can protect our planet and ensure a healthier, safer future for all children.
