Extreme Weather

The Increase in Extreme Weather Around the World

You’ve probably noticed it yourself – those sweltering summer days seem hotter, those rainy days feel more intense, and the news seems to frequently report one extreme weather event after another. So, what’s going on?

Over the past few decades, there’s been a noticeable uptick in extreme weather events around the globe. From raging wildfires in California and Australia to hurricanes battering the Gulf Coast, to heatwaves in Europe, and even unprecedented snowfalls in places that don’t typically see much snow – the world’s weather seems to be, for lack of a better word, acting up.

This isn’t just bad luck. There’s a growing consensus among scientists that the increasing frequency and intensity of these extreme weather events are strongly linked to human-induced climate change.

As we pump more carbon dioxide and other greenhouse gases into the atmosphere, we’re effectively trapping more heat on our planet. This doesn’t just make things warmer overall, but it supercharges many of the natural systems and cycles that drive our weather.

For example:

  • Heatwaves: As average temperatures rise, heatwaves become more frequent and more intense.
  • Storms: A warmer atmosphere can hold more moisture, leading to more intense rainfall and storms.
  • Wildfires: Rising temperatures can lead to drier conditions, making forests and grasslands more susceptible to fires.
  • Hurricanes: Warm Ocean water fuels hurricanes, so as sea surface temperatures rise, we could see more powerful hurricanes.

The Consequences of Climate Change Beyond Rising Temperatures

Now, if you’re thinking, “Okay, it’s getting warmer, and the weather’s getting wilder, but that’s it, right?” Well, there’s more to the story. The consequences of climate change go far beyond just temperature rises.

  • Sea Level Rise: Warming temperatures are causing polar ice caps and glaciers to melt, which contributes to rising sea levels. This threatens coastal cities and can lead to the displacement of large populations.
  • Ocean Acidification: As the ocean absorbs more CO2, its pH level drops, leading to ocean acidification. This can have devastating effects on marine life, especially on creatures that rely on calcium carbonate for their shells and skeletons, like corals and some types of plankton.
  • Biodiversity Loss: Changing climates means that many plants and animals can’t adapt quickly enough, leading to reduced populations or even extinction. This affects ecosystems and the services they provide.
  • Shifts in Agricultural Patterns: Some regions may become too dry or too hot for traditional crops, threatening food supplies and economies.
  • Human Health: Higher temperatures can exacerbate respiratory and cardiovascular problems, enable the spread of diseases like malaria and dengue fever, and even strain medical infrastructure due to heat-related illnesses.
  • Economic Impact: Extreme weather events, changes in agricultural yields, and health challenges can have cascading economic impacts, ranging from lost livelihoods to strains on national economies.

While it’s easy to focus on the thermometer when we talk about climate change, the real story is much broader. It’s about how a changing climate touches every part of our lives – from the food we eat, the air we breathe, the places we call home, and even our overall well-being. As the world grapples with these challenges, understanding the vast implications of climate change becomes ever more crucial.

Extreme weather is the “new norm”

“This is the new normal and does not come as a surprise,” said Alvaro Silva, a climate expert with WMO. “The frequency and intensity of many extremes, such as heatwaves and heavy precipitation, have increased in recent decades.…read more

Extreme Weather: Understanding the Basics

Extreme weather! It sounds dramatic, doesn’t it? And indeed, it is. Extreme weather refers to unusual, severe, or unseasonal weather conditions. These can be events that break historical records like the hottest day ever recorded in a city or a sudden, unexpected downpour that leads to flooding.

Imagine walking into a room where a bunch of people are throwing paper planes. If one of those paper planes does something particularly unexpected – like making three loops in the air before landing – you could say that’s the “extreme” behaviour of that plane. Similarly, when the weather does something that’s out of the ordinary based on what’s expected or typical for that place and time of year, we call it extreme weather.

Events like hurricanes, tornadoes, heavy snowfalls, heatwaves, and droughts can all fall under this category.

The Difference Between Climate and Weather

Ever heard someone say, “Oh, this cold spell is such strange weather for June!” and someone else chimes in with, “But, remember, weather isn’t the same as climate!”? It might sound like they’re just trying to be smart, but there’s a genuine distinction here.

Weather refers to short-term changes in atmospheric conditions. Think of it like your mood on a given day. You might be grumpy in the morning, cheerful by lunchtime, and sleepy by evening. That’s the “weather” of your mood.

Climate, on the other hand, is like your personality. It’s the average of the weather over a long period, typically 30 years or more. It encompasses the overall, long-term patterns and averages of temperature, humidity, rainfall, and other meteorological conditions in a region. So, when we say a place has a “tropical climate,” we’re talking about its consistent patterns over the years, not how it feels on any particular day.

The Greenhouse Effect and Its Impact on Global Temperatures

Picture a greenhouse. It’s made mostly of glass and is designed to trap heat, right? Plants inside the greenhouse stay warm, even if it’s chilly outside. Our Earth behaves somewhat like this, thanks to gases in our atmosphere.

Certain gases, like carbon dioxide (CO2) and methane (CH4), are known as greenhouse gases. When the Sun’s rays hit the Earth, some of that energy is reflected back towards space. Greenhouse gases act like the glass of a greenhouse: they trap some of this outgoing energy, keeping heat from escaping too quickly. This natural process is essential because, without it, Earth would be much colder, and life as we know it would be impossible.

But here’s the twist: human activities, especially the burning of fossil fuels like coal, oil, and natural gas, have increased the concentration of these greenhouse gases in the atmosphere. More greenhouse gases mean more heat is trapped, leading to a rise in Earth’s average temperature, a phenomenon commonly known as global warming. This, in turn, influences the broader climate system, potentially leading to more frequent and severe extreme weather events and other shifts in our long-term weather patterns.

In essence, while the greenhouse effect is a natural and vital process, the significant increase in greenhouse gases due to human activity has accelerated the warming of our planet, and that’s causing a ripple effect on our climate.

How Do You Deal with The Changing Climate

There are many ways in which climate change is affecting our planet. Some of these effects are already becoming obvious, while others will only become apparent in the future.…read more

Climate change isn’t just about a gradual increase in average global temperatures; it’s also about the increasing frequency and severity of extreme weather events. Think of the climate as the long-term average of weather over time and in specific regions, and you’ll see how even slight shifts in the climate can lead to dramatic weather changes.

In essence, as we pump more greenhouse gases like carbon dioxide (CO2) and methane (CH4) into the atmosphere, we’re effectively adding energy to the Earth’s system. This additional energy disrupts the equilibrium, leading to a more dynamic and unpredictable atmosphere, which then manifests as extreme weather.

How a Warming Climate can Alter Weather Patterns

To understand this further, let’s delve into some real-life examples:

Heatwaves in Europe and North America

  • What’s Happening: Over the past few decades, we’ve witnessed more frequent, longer, and hotter heatwaves in regions like Europe and North America. Cities like Paris, Madrid, and even places in Canada, which were historically cooler, have experienced record-breaking temperatures.
  • Why It’s Happening: As the average global temperature rises due to increasing greenhouse gas concentrations, heatwaves become more likely. The jet stream, a high-altitude wind pattern, can also get ‘stuck’, leading to prolonged periods of hot, dry weather in certain areas.

Intensified Hurricanes and Cyclones in the Atlantic and Pacific

  • What’s Happening: Hurricanes are becoming more powerful and more destructive. This means they’re reaching higher categories, causing more damage, and even stalling over regions for extended periods (think of Hurricane Harvey over Houston in 2017).
  • Why It’s Happening: Warm Ocean waters are the fuel for hurricanes. As sea surface temperatures rise, there’s more energy available to intensify these storms. Additionally, rising sea levels can exacerbate storm surges, leading to more extensive flooding.

Longer and More Severe Droughts in Africa and Australia

  • What’s Happening: Regions like the Sahel in Africa and large parts of Australia are witnessing extended dry spells, leading to water shortages and crop failures.
  • Why It’s Happening: A warmer atmosphere can hold more moisture, meaning that when it does rain, it’s often more intense. But paradoxically, it can also mean prolonged periods without rain in certain regions, leading to droughts.

Increased Frequency of Heavy Rainfall and Flooding in Asia and South America

  • What’s Happening: Areas like South Asia have experienced flash floods, while parts of South America have seen rivers overflow their banks, inundating towns and fields.
  • Why It’s Happening: Again, a warmer atmosphere can hold more moisture. So, when conditions are right for rain, there’s a lot more water vapour available to fall, leading to heavy downpours. This can overwhelm drainage systems and natural water courses, resulting in flooding.

While weather has always been dynamic and unpredictable, the fingerprints of climate change are becoming more evident in the increasing severity and frequency of extreme events. Addressing climate change means not just preparing for warmer days, but also bracing for more intense storms, longer droughts, and unexpected weather shifts.

The Science Behind the Extreme Weather Connection

At a high level, Earth’s weather is the result of energy redistribution. Our planet receives energy from the sun and releases it back into space. As global temperatures rise, largely due to human activities like burning fossil fuels, the energy balance gets disrupted. This often results in extreme weather events. Think of it as adding extra heat to a simmering pot; things are bound to bubble up more intensely.

Ocean Temperature Rise and its Effects on Hurricanes

Oceans act like vast, slow-churning storage heaters for the planet. As they absorb more heat from global warming, surface waters become warmer. Now, hurricanes feed off warm water. Warmer waters essentially act like steroids for these storms, giving them more energy, making them wetter, stronger, and even more destructive. This is why scientists are observing more intense hurricanes in a warming world.

Melting Glaciers and the Influence on Sea Level and Coastal Storms

Glaciers are Earth’s giant ice reservoirs. As temperatures rise, glaciers melt faster than they can accumulate snow. This meltwater pours into the oceans, leading to sea-level rise. Higher sea levels mean coastal areas get inundated more easily during storms. Thus, a city that might have been safe from a particular storm surge 50 years ago might now face flooding due to the combined effects of higher sea levels and more intense storms.

Shifts in Jet Streams and Altered Weather Patterns

Jet streams are like atmospheric conveyor belts. They’re fast-flowing air currents that help move and distribute weather systems around the world. With the warming of the Arctic happening at a faster rate than the rest of the planet, the temperature gradient (difference) between the Arctic and areas to its south is reduced.

This can cause the jet streams to meander more and even become “stuck” in certain patterns. This stagnation can lead to prolonged weather conditions: think of heatwaves, cold snaps, or endless rainy days, depending on where you are.

Extreme Weather Can Further Exacerbate Climate Change

Nature has a funny way of creating loops, where one event triggers another, which intensifies the first event. For example, as the permafrost (permanently frozen soil) melts due to rising temperatures, it releases methane, a greenhouse gas much more potent than CO2 in trapping heat. This release of methane further accelerates global warming, which in turn, causes more permafrost to melt.

This cyclical process is a classic example of a feedback loop, and it underscores the urgency of addressing climate change sooner rather than later.

Our Earth’s system is interconnected in ways that can sometimes lead to drastic and intense changes. The extreme weather, rising oceans, shifting atmospheric patterns, and feedback loops are all intertwined tales of a planet in flux. As stewards of Earth, it becomes imperative for us to understand these changes and act responsibly.

Extreme Weather Societal and Economic Impact

Extreme weather is more than just a day when you might need an umbrella or an extra layer of clothing. It has profound implications for society and the economy. Think about major hurricanes, floods, droughts, and wildfires. These aren’t merely natural phenomena; they disrupt lives, tear apart communities, and can set back economies by years if not decades. Infrastructure like roads, bridges, and power grids are heavily affected.

And then there’s the emotional and societal strain: people lose homes, livelihoods, and even loved ones. The ripples of these events shape policies, push for innovations in resilience and adaptation, and prompt entire communities to reconsider where and how they live.

The Cost on Global Economies

Numbers don’t lie. According to a 2020 report, the last four decades saw losses of over $2.6 trillion due to extreme weather, a stark increase from previous decades. And it’s not just the immediate repair costs. The disruption of supply chains, loss of agricultural yields, and decline in tourism are less visible but equally palpable financial setbacks.

Economies with a strong reliance on agriculture or coastal tourism, for example, are particularly vulnerable. As extreme weather events become more frequent and intense, there’s a looming economic shadow cast on many nations, making them reconsider their future development paths and investment priorities.

The Impact on Agriculture

Ah, the bread and butter (quite literally) of many economies. Climate change introduces a myriad of challenges for farmers. First, there’s the unpredictability. Traditionally, farmers could rely on historical data to predict weather patterns, but now those are less reliable. Droughts dry up the soils, reducing yields. Floods wash away crops. And changing temperatures and rainfall patterns can make previously fertile lands less suitable for traditional crops.

This doesn’t just mean fewer apples or wheat. It has serious implications for food security. As yields drop and crop failures become more common, food prices can rise, making basic sustenance less accessible for many, especially in vulnerable regions.

Human Health

Extreme weather isn’t only wreaking havoc outside our homes; it’s impacting our very well-being. Rising temperatures lead to heatwaves, which can result in heat-related illnesses or even fatalities, particularly among vulnerable groups like the elderly. Then there’s the spread of diseases. Warmer climates are perfect for disease vectors like mosquitoes, broadening the regions where diseases like malaria or dengue can spread.

And let’s not forget the strain on health infrastructure. Hospitals can be overwhelmed during extreme events, and access to medical care becomes difficult when roads are flooded, or communities are isolated.


Imagine having to leave everything behind because your home is no longer habitable. This isn’t a dystopian novel; it’s a reality for many. Extreme weather events and the consequent sea-level rise are displacing millions. These “climate refugees” aren’t just moving to the next town; they’re crossing borders, leading to geopolitical tensions and challenges in integration.

Islands in the Pacific, coastal regions in Asia, and even parts of the US Gulf Coast are facing this pressing concern.

In essence, extreme weather isn’t an isolated problem. It’s an intricate web of challenges that demands global attention, cooperation, and action. As we advance further into the 21st century, our ability to adapt and mitigate these challenges might just be the most defining aspect of our time.

Carbon Emissions Are Adding to Greenhouse Gases

Increased amounts of greenhouse gases cause the temperature of Planet Earth’s surface to rise. It’s this increase in temperature that causes changes in weather patterns and climate change.…read more

Adaptation and Mitigation Strategies for Extreme Weather

The impacts of climate change aren’t just in the future; they’re happening now. Rising global temperatures have increased the frequency and intensity of extreme weather events, from heatwaves to hurricanes. Two primary strategies are adaptation and mitigation.

While mitigation is about reducing the flow of greenhouse gases into the atmosphere (essentially addressing the cause), adaptation is about adjusting to the current and future climate impacts (addressing the symptoms).

Infrastructure Changes

  • Building Flood Barriers: With rising sea levels and increased rainfall, floods are becoming more common. Flood barriers, like sea walls, dikes, and levees, are effective tools to keep waters at bay, protecting urban centres and agricultural lands.
  • Redesigning Cities for Heat: Urban heat islands – city areas significantly warmer than their surrounding rural zones – can be deadly during heatwaves. To combat this, cities can promote green rooftops, reflective materials, more parks, and strategically planted trees. This not only offers shade but helps in absorbing rainwater and reducing surface temperatures.
  • Adopting Water Conservation Techniques: Water scarcity is a growing concern. Techniques such as rainwater harvesting, water recycling, and drought-tolerant landscaping can ensure a more sustainable water supply.

Policy Recommendations

  • Enhancing Early Warning Systems: Advanced warning can save lives and reduce damage. Improved meteorological technology and communication networks can ensure people are prepared well in advance of extreme weather events.
  • Investing in Renewable Energy: Shifting away from fossil fuels reduces greenhouse gas emissions. Solar, wind, hydro, and geothermal energy are not only sustainable but are becoming increasingly cost-effective.
  • Setting Stricter Emissions Targets: Governments can set aggressive emissions reduction targets, pushing industries towards greener technologies and methods.

Community-level Initiatives

  • Local Resilience Building: Local solutions can sometimes be the most effective. For example, community-shared solar power installations or community gardens can provide local, sustainable resources.
  • Education: Informing communities about the risks of climate change and ways to combat it can foster proactive measures. This can range from workshops on sustainable farming to school curriculums on conservation.
  • Preparedness: Encouraging households to have emergency plans, or communities to have designated shelters and relief strategies, can make all the difference during extreme events.

Global Cooperation

  • International Agreements: The Paris Agreement is a prime example of global efforts to combat climate change. Such treaties provide a framework for accountability and shared targets.
  • Funding Mechanisms: Initiatives like the Green Climate Fund help developing countries in their climate endeavours, ensuring that economic disparities don’t hinder global climate action.
  • Joint Research Efforts: Climate change is a shared challenge. Collaborative research can pool resources and expertise, leading to innovative solutions more rapidly than isolated efforts.

Tackling the challenges posed by climate change and extreme weather requires a multifaceted approach, from local grassroots initiatives to broad international collaborations. It’s not just about saving the environment; it’s about preserving our way of life, our communities, and our future.

Extreme Weather and The Power of Individual Action

Over the past few decades, we’ve seen an unsettling uptick in extreme weather events. From record-breaking hurricanes to paralysing heatwaves, the shifts in our climate are increasingly hard to ignore. Though it might feel like the responsibility of governments or large corporations to combat this issue, it’s essential to realise that individual actions collectively make a big difference.

Imagine a single raindrop thinking it doesn’t contribute to a flood, yet thousands of such droplets can lead to surges that shape landscapes. Similarly, your individual choices, when combined with millions of others, can send a powerful message, leading to widespread changes.

Personal Changes to Reduce Carbon Footprint

  • Sustainable Consumption: Every time we buy something, we’re casting a vote for the kind of world we want. Opting for products made using sustainable methods or reducing the sheer quantity of items we purchase can significantly reduce our carbon footprint. Think about choosing organic, shopping locally, or even embracing a minimalist lifestyle. Remember, quality often trumps quantity.
  • Transportation: One of the most immediate ways to cut down your carbon footprint is to reevaluate how you get around. Whether it’s carpooling, cycling, using public transport, or even investing in an electric car, every little change helps. Plus, with advancements in technology, alternative means of transportation are becoming more efficient and accessible every day.
  • Energy Use: Simple actions like switching to LED bulbs, using energy-efficient appliances, and turning off lights when not needed can cut down your energy consumption. Going a step further, you can look into solar panels or sourcing your energy from renewable providers.

Community Awareness and Grassroots Movements

While individual actions matter, there’s no denying the impact that comes from collective action. Community awareness drives local changes, leading to a ripple effect that can influence broader policy.

Grassroots movements are the heartbeats of environmental change. When local communities rally behind a cause, it draws attention. It demonstrates to policymakers that their constituents care about specific issues, prompting them to reconsider their stances and make better-informed decisions. Moreover, grassroots movements are powerful tools for education, ensuring that more and more people are informed about the crisis and inspired to make a difference.

Individuals and Communities Making a Difference

  • Greta Thunberg: A young Swedish girl began skipping school on Fridays to protest in front of the Swedish parliament, demanding stronger climate action. Her “Fridays for Future” movement ignited a global youth-led protest, proving that age is just a number when you’re passionate about change.
  • The Forest Man of India: Jadav Payeng, concerned by the erosion in his homeland, began planting trees on a barren sandbar in Assam, India, in the late 1970s. Decades later, that barren land is now a 1,360-acre forest that houses tigers, rhinos, and various bird species.
  • Community Initiatives: From local urban farms sprouting up in cities worldwide to communities banning single-use plastics or launching recycling initiatives, communities are coming together in innovative ways. One such example is the village of Kamikatsu in Japan, which aims for zero waste by sorting its trash into a staggering 45 categories!

Combating climate change is a collective endeavour. While the problem is monumental, history has shown us that when individuals and communities come together with a shared purpose, they possess the power to instigate real, lasting change.


In today’s rapidly changing world, understanding the connection between climate change and extreme weather is paramount. This linkage, backed by robust scientific evidence, underscores that our planet’s health directly influences the intensity and frequency of storms, heatwaves, and floods.

Recognising this relationship not only emphasises the urgency of addressing global warming but also prepares us better for its consequent challenges.

It’s akin to piecing together a vast puzzle: with each connection we make, our picture of the environment grows clearer.

Ultimately, our knowledge shapes our resilience, ensuring a safer, more informed future for generations to come.


What is the link between climate change and extreme weather events?

Climate change, primarily driven by human activities such as burning fossil fuels, deforestation, and industrial processes, has led to a rise in global temperatures. This warming affects atmospheric dynamics and causes disruptions in weather patterns. As a result, we’re seeing more frequent and intense extreme weather events like hurricanes, heatwaves, floods, and droughts.

How does global warming intensify hurricanes and typhoons?

Hurricanes and typhoons draw their energy from warm ocean waters. As global temperatures rise, ocean surface temperatures also increase. Warmer waters lead to more evaporation, fuelling these storms, and making them potentially stronger and more devastating. Moreover, rising sea levels can exacerbate storm surges and flooding during such events.

Can we attribute any specific weather event directly to climate change?

While it’s challenging to pin a single event solely on climate change, scientists can estimate the extent to which human-induced climate change makes certain events more likely or severe. Using a method called “attribution science,” researchers can compare today’s conditions with historical, pre-industrial conditions to determine the human influence on specific events.

Is there a connection between climate change and droughts?

Yes, there is. With rising temperatures, evaporation rates increase, drying out soil and vegetation faster. In some regions, changing precipitation patterns can lead to less rainfall. Both these factors contribute to prolonged and more severe drought conditions, impacting agriculture, water supply, and ecosystems.

How is climate change affecting winter storms?

It may seem counterintuitive, but warmer temperatures can influence the frequency and intensity of winter storms. Warmer air can hold more moisture, leading to heavier snowfalls in some areas. Moreover, the shifting jet stream, influenced by the melting Arctic, can lead to prolonged cold spells and intense storms in certain regions.

What can we do to mitigate the impacts of extreme weather due to climate change?

Mitigating the effects of climate change involves reducing greenhouse gas emissions by transitioning to renewable energy sources, reforesting, and adopting sustainable practices. Preparing for extreme weather involves building resilient infrastructure, developing early warning systems, and implementing adaptive management strategies.
