As we navigate through 2025, climate change has shifted from a distant concern to a daily reality affecting communities worldwide. In January 2025, global temperatures soared to 1.75°C above pre-industrial levels, marking the 18th month in the last nineteen months where temperatures exceeded the critical 1.5°C threshold set by the Paris Agreement. This alarming trend shows the urgency of addressing climate change head-on.
The impacts are no longer abstract. In Los Angeles, devastating wildfires in January 2025 forced the evacuation of 180,000 residents and resulted in at least 10 fatalities. These events highlight the tangible consequences of a warming planet.
Despite the emergence of La Niña, which typically brings cooler global temperatures, the planet continues to experience unprecedented warmth. This paradox emphasizes the dominant influence of human-induced greenhouse gas emissions on our climate.
In this comprehensive guide, we’ll explore the current state of climate change, examine the latest scientific findings, share real-world experiences, and offer practical, actionable steps. This is more than information; it’s a call to action for us to engage in meaningful solutions.
The State of the Planet: 2025 Climate Snapshot
Rising Global Temperatures
Over the past century, our planet’s temperature has steadily increased. Recent data indicates that the global average temperature is approximately 1.2°C higher than pre-industrial levels. This warming has intensified heat waves, droughts, and severe weather events worldwide.
Sea-Level Rise Threatens Coastal Cities
Coastal regions are experiencing the dual challenge of rising sea levels and sinking land. A 2025 NASA study revealed that cities like San Francisco and Los Angeles are subsiding, exacerbating the effects of sea-level rise. Projections suggest that California could see sea levels rise between 6 and 14.5 inches by 2050, posing significant risks to coastal communities.
Surge in Climate-Induced Displacement
Disasters related to climate change have displaced millions. By the end of 2023, approximately 7.7 million people were internally displaced due to such disasters. As extreme weather events become more frequent and intense, this number is expected to rise, which shows the urgent need for comprehensive climate action.
Energy Demand and the Shift to Renewables
The global demand for electricity is on the rise, driven by factors like increased use of air conditioning during heat waves and the expansion of data centers. The International Energy Agency (IEA) forecasts a 4% annual growth in electricity demand through 2027. Encouragingly, renewables are projected to meet about 95% of this growth, with their share in global electricity generation expected to reach 35% by 2025.
A Mixed Outlook
While the expansion of renewable energy offers hope, challenges remain. The IEA anticipates that global CO₂ emissions from electricity generation will plateau over the next few years, highlighting the need for accelerated efforts in emission reductions.
Melting Realities: True Stories from the Frontlines
Story 1: Displaced by Rising Seas in Bangladesh
In the low-lying coastal regions of Bangladesh, rising sea levels have become an unrelenting adversary. Nur Jahan, once a resident of Kutubdia Island, experienced this firsthand. In 1991, a devastating cyclone engulfed her home, claiming the lives of all six of her children. With her land submerged and livelihood destroyed, she sought refuge in Cox’s Bazar on the mainland. Over the years, thousands like Nur have been forced to abandon their ancestral homes as the sea continues its encroachment. The UNHCR reports that entire communities from Kutubdia have relocated to urban areas, only to face overcrowded conditions and limited resources.
Approximately two-thirds of Bangladesh lies less than five meters above sea level, making it exceptionally vulnerable. Projections suggest that by 2050, a 50 cm rise in sea level could submerge around 11% of the nation’s land, potentially displacing 15 million people. The salinization of freshwater sources further exacerbates the crisis, rendering vast tracts of agricultural land barren and jeopardizing the livelihoods of millions.
Story 2: Farming Amidst Drought in California
In California’s San Joaquin Valley, farmers grapple with the dual challenges of drought and water scarcity. Don Cameron, a seasoned farmer at Terranova Ranch, has witnessed the transformation of the region’s climate patterns. To combat the erratic swings between drought and deluge, Cameron pioneered a method to use floodwaters to recharge depleted aquifers. By diverting excess floodwater onto his fields, he not only replenishes groundwater reserves but also mitigates flood risks downstream. This innovative approach has raised the local water table by 40 feet since the 2017 floods.
However, the path hasn’t been devoid of obstacles. California’s water rights present legal and political challenges. Disputes over the ownership and usage of floodwaters complicate the implementation of such recharge projects. Despite these hurdles, Cameron’s efforts show the potential of adaptive strategies in ensuring the sustainability of agriculture in the face of climate change.

Key Drivers of Climate Change in 2025
1. Fossil Fuels Still Dominate
Despite advancements in renewable energy, coal, oil, and natural gas continue to supply a substantial portion of the world’s energy needs. This reliance is deeply rooted in the economic structures of major nations. For instance, the United States, Saudi Arabia, and Russia have historically provided significant financial support to the fossil fuel industry. In 2022, global fossil fuel subsidies reached a staggering $7 trillion, accounting for 7.1% of the world’s GDP. These subsidies not only strain public finances but also hinder the transition to cleaner energy sources.
2. Deforestation & Agriculture
The Amazon rainforest, often referred to as the Earth’s lungs, has experienced increased deforestation due to illegal mining and expansive soy production. This destruction not only releases vast amounts of carbon dioxide but also diminishes the planet’s capacity to absorb existing CO₂. Additionally, livestock farming is a significant contributor to greenhouse gas emissions. However, the exact figures are under scrutiny. In 2024, over 20 scientific experts criticized the UN’s Food and Agriculture Organization for inaccuracies in their report on livestock emissions, suggesting that the impact of dietary changes on reducing agricultural greenhouse gases might be understated. This highlights the complexities involved in addressing emissions from agriculture.
3. Industrial Emissions & Consumerism
Our modern lifestyles, characterized by fast fashion, the latest tech gadgets, and significant food waste, have environmental consequences. By 2024, global plastic production had surged to 400 million metric tons, a dramatic increase from 2 million metric tons in 1950. Alarmingly, only 10% of this plastic is recycled, leaving the majority to pollute our ecosystems. This accumulation not only harms marine life but also contributes to the broader climate crisis.
Environmental Tipping Points: Are We Too Late?
Wildfires and Heatwaves
The summer of 2024 was the hottest on record globally, with temperatures 0.69°C above the 1991-2020 average, surpassing the previous record set in 2023. Europe endured deadly heatwaves and extreme weather from as early as June, impacting millions and causing significant economic losses. In Canada, the 2023–2024 fire season was marked by unprecedented fire extent and emissions, with deadly fast-moving fires affecting various regions. Australia also faced severe wildfires, with at least four fires burning in the state of Victoria as weather conditions worsened. These events contributed to a tragic human toll, with thousands of heat-related deaths reported globally in 2024.
Glacier Retreat & Arctic Warming
Greenland’s ice sheet is experiencing significant and accelerating ice loss, with current estimates indicating an average reduction of approximately 270 billion metric tons per year between 2002 and 2023. This substantial ice loss contributes to rising sea levels and has the potential to disrupt global ocean currents.
Recent studies suggest that the Arctic Ocean could experience its first ice-free summer day as early as 2027, earlier than previously anticipated due to rapid melting. This transformation is expected to have profound effects on global climate patterns, including alterations to the jet stream and precipitation systems.
Dr. Johan Rockström, Director of the Potsdam Institute for Climate Impact Research, has emphasized the urgency of the situation, stating, “We must admit that we have underestimated the risks of unleashing irreversible changes, where the planet self-amplifies global warming.”
These changes are not distant threats—they are already altering weather patterns, sea levels, and global food systems in real time.
Climate Change Performance Index 2025 and Heroes of the Year: Who’s Leading the Way?
The Climate Change Performance Index (CCPI) 2025, developed by Germanwatch, the NewClimate Institute, and the Climate Action Network (CAN), offers a transparent, comparative look at climate protection efforts across 63 countries and the EU—together responsible for over 90% of global greenhouse gas (GHG) emissions.

Leah is a powerful advocate for climate justice in East Africa. At just 20 years old, she’s leading national tree-planting campaigns, speaking at UN forums, and calling out greenwashing by world leaders.
“We don’t want empty promises. We want justice. We want solutions that don’t just benefit the rich.”
Technology and Innovation: Bright Spots
Clean Energy Surges
The past decade has witnessed a dramatic decline in solar energy costs. Between 2009 and 2019, the cost of electricity from new solar power plants plummeted by 89%, making it more affordable than ever. This reduction has sparked a solar boom across Africa, where approximately 8% of households in Sub-Saharan Africa with electricity access now rely on off-grid solar systems. This shift is illuminating homes and empowering communities that were previously without reliable electricity.
Carbon Removal & Soil Regeneration
Innovative companies like Climeworks are making significant strides in carbon capture technology. In May 2024, Climeworks inaugurated Mammoth, their second large-scale Direct Air Capture and Storage facility, capable of capturing up to 36,000 tons of CO₂ annually.

Health, Inequity, and Climate Justice
Public Health Crisis
Air pollution is a silent killer affecting millions worldwide. The World Health Organization reports that the combined effects of ambient and household air pollution are responsible for approximately 7 million premature deaths annually. This staggering number shows the pervasive impact of polluted air on global health. Moreover, climate change is facilitating the spread of diseases like dengue and malaria into regions previously unaffected, exacerbating public health challenges.
The Inequality Gap
The injustice of climate change is stark: Africa contributes just about 2 to 3 percent of global carbon dioxide emissions from energy and industrial sources, yet it bears the brunt of climate-related hardships. Droughts and erratic weather patterns have led to severe food shortages, with over 57 million people facing hunger across the Horn, East, Central, and West Africa. This disparity highlights a cruel paradox—those least responsible for climate change suffer its most devastating consequences.
As Ugandan climate activist Vanessa Nakate poignantly states, “These are some of the injustices of the climate crisis—those who didn’t cause the climate crisis, those who aren’t responsible for the rising global emissions, are the ones who are suffering the most.”
Addressing these challenges requires a concerted effort to reduce emissions globally and support vulnerable communities disproportionately affected by climate change. Climate justice is not just an ethical imperative; it’s essential for the survival and well-being of millions.
