Is typhoon Haiyan linked to climate change?

As the devastating storm has only just happened, it is too soon for any research to have been done on whether global warming influenced typhoon Haiyan. But there are good reasons for expecting that it has (see below). Furthermore, the tools exist to determine how much climate change may have intensified the typhoon. They have already been used on other extreme weather events, giving a clear scientific answer that climate change had dramatically increased the risk of heatwaves and floods, for example.

How could climate change affect typhoons?

Typhoons, hurricanes and all tropical storms draw their vast energy from the warmth of the sea. As Prof Will Steffen, at the Australian National University, says: "We know sea-surface temperatures are warming pretty much around the planet, so that's a pretty direct influence of climate change on the nature of the storm."

Another key factor is the temperature difference between sea level and the top of the storm, as this gradient is the heat engine that drives storm. Scientists think that climate change is increasing this difference.

Yes. Prof Myles Allen, at the University of Oxford, says: "The current consensus is that climate change is not making the risk of hurricanes any greater, but there are physical arguments and evidence that there is a risk of more intense hurricanes." A Nature Geoscience research paper from 2010 found that global warming will increase the average intensity of the storms while the total number of storms will fall, meaning fewer but more severe cyclones. It also found that rainfall in the heart of the storms will increase by 20%.

A 2013 study by MIT's Prof Kerry Emmanuel agreed that the most intense cyclones – category 3 to 5 – will increase, but the work suggested smaller cyclones would also increase. It also found that "increases in tropical cyclones are most prominent in the western North Pacific", ie where typhoon Haiyan struck.

In 2011, a synthesis report from the Intergovernmental Panel on Climate Change concluded that the average wind speeds in cyclones are likely to increase, as was the frequency of heavy rainfall, but it noted the difficulty of linking changes in complex events like cyclones to climate change.

What does this mean for the loss of life and damage caused by the storms?

It will get worse. Rising sea levels already means that the storm surges – the huge waves that crash on to coastal areas and are the most deadly feature of cyclones – have a headstart. As climate change intensifies cyclones, the storm surges get bigger. The greater downpours during the cyclones also adds to the risk of flooding.

You said some extreme weather events can be directly linked to climate change. How is that done?

It is called attribution and uses detailed computer modelling to replicate the heatwave, flood or other meteorological disaster. Then the models are run again – often thousands of times, but without the additional heat in the system trapped by the greenhouse gases emitted from fossil fuel burning. The differences between the results shows the effect of climate change.

A study by Allen showed that the severe flooding in the UK in 2000 was made two to three times more likely by global warming. Another study showed the extreme Russian heatwave of 2010, which resulted in 50,000 deaths, was made three times more likely by climate change,

Allen said the influence of climate change on typhoon Haiyan could be calculated. "This is a question we could answer if we diverted the right resources to it," he said. "If we used the same tools as are used now to make seasonal weather forecasts, there would be a straightforward answer."

Allen said such attribution studies should be prioritised. "It's first things first: we should know now how climate change is affecting us rather than how it will affect us in 100 years' time. It is a common misconception that climate change affects everyone. It affects some people a lot and others not very much – but we don't know who is who."

Though we often think about human-induced climate change as something that will happen in the future, it is an ongoing process. Ecosystems and communities in the United States and around the world are being impacted today.

Global temperatures rose about 1.98°F offsite link (1.1°C) from 1901 to 2020, but climate change refers to more than an increase in temperature. It also includes sea level rise, changes in weather patterns like drought and flooding, and much more. Things that we depend upon and value — water, energy, transportation, wildlife, agriculture, ecosystems, and human health — are experiencing the effects of a changing climate.

A complex issue

The impacts of climate change on different sectors of society are interrelated. Drought can harm food production and human health. Flooding can lead to disease spread and damages to ecosystems and infrastructure. Human health issues can increase mortality, impact food availability, and limit worker productivity. Climate change impacts are seen throughout every aspect of the world we live in. However, climate change impacts are uneven across the country and the world — even within a single community, climate change impacts can differ between neighborhoods or individuals. Long-standing socioeconomic inequities can make  underserved groups, who often have the highest exposure to hazards and the fewest resources to respond, more vulnerable. 

The projections of a climate change-impacted future are not inevitable. Many of the problems and solutions offsite link are known to us now, and ongoing research continues to provide new ones.  Experts believe there is still time to avoid the most negative of outcomes by limiting warming offsite link  and reducing emissions to zero as quickly as possible. Reducing our emissions of greenhouse gases will require investment in new technology and infrastructure, which will spur job growth. Additionally, lowering emissions will lessen harmful impacts to human health, saving countless lives and billions of dollars in health-related expenses.

Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response.

Our changing climate

We see climate change affecting our planet from pole to pole. NOAA monitors global climate data and here are some of the changes NOAA has recorded. You can explore more at the Global Climate Dashboard.

  • Global temperatures rose about 1.8°F (1°C) from 1901 to 2020.
  • Sea level rise has accelerated from 1.7 mm/year throughout most of the twentieth century to 3.2 mm/year since 1993.
  • Glaciers are shrinking: average thickness of 30 well-studied glaciers has decreased more than 60 feet since 1980.
  • The area covered by sea ice in the Arctic at the end of summer has shrunk by about 40% since 1979.
  • The amount of carbon dioxide in the atmosphere has risen by 25% since 1958, and by about 40% since the Industrial Revolution.
  • Snow is melting earlier compared to long-term averages.

Water

Changes to water resources can have a big impact on our world and our lives.

Flooding is an increasing issue as our climate is changing. Compared to the beginning of the 20th century, there are both stronger and more frequent abnormally heavy precipitation events across most of the United States.

Conversely, drought is also becoming more common, particularly in the Western United States. Humans are using more water, especially for agriculture. Much like we sweat more when it is hot out, higher air temperatures cause plants to lose, or transpire, more water, meaning farmers must give them more water. Both highlight the need for more water in places where supplies are dwindling.

Snowpack is an important source of freshwater for many people. As the snow melts, freshwater becomes available for use, especially in regions like the Western United States where there is not much precipitation in warmer months. But as temperatures warm, there is less snow overall and snow begins to melt earlier in the year, meaning snowpack may not be a reliable source of water for the entire warm and dry seasons.

The Redlands Mesa area outside Hotchkiss, Colorado, is particularly at risk to wildfires, but with funding from NOAA’s Environmental Literacy Program, local high school students are taking action to tackle their community’s vulnerability to this hazard.

Food

Our food supply depends on climate and weather conditions. Although farmers and researchers may be able to adapt some agricultural techniques and technologies or develop new ones, some changes will be difficult to manage. Increased temperatures, drought and water stress, diseases, and weather extremes create challenges for the farmers and ranchers who put food on our tables.

Human farm workers can suffer from heat-related health issues, like exhaustion, heatstroke, and heart attacks. Rising temperatures and heat stress can also harm livestock. 

Human health

Climate change is already impacting human health. Changes in weather and climate patterns can put lives at risk. Heat is one of the most deadly weather phenomena. As ocean temperatures rise, hurricanes are getting stronger and wetter, which can cause direct and indirect deaths. Dry conditions lead to more wildfires, which bring many health risks. Higher incidences of flooding can lead to the spread of waterborne diseases, injuries, and chemical hazards. As geographic ranges of mosquitoes and ticks expand, they can carry diseases to new locations.

The most vulnerable groups, including children, the elderly, people with preexisting health conditions, outdoor workers, people of color, and people with low income, are at an even higher risk because of the compounding factors from climate change. But public health groups can work with local communities to help people understand and build resilience to climate change health impacts.

Examples of populations at higher risk of exposure to adverse climate-related health threats are shown along with adaptation measures that can help address disproportionate impacts. When considering the full range of threats from climate change as well as other environmental exposures, these groups are among the most exposed, most sensitive, and have the least individual and community resources to prepare for and respond to health threats. White text indicates the risks faced by those communities, while dark text indicates actions that can be taken to reduce those risks. (EPA (National Climate Assessment))

Fries depend on potatoes, and like all crops, potatoes have a preferred climate. How long will America’s favorite side dish have a safe spot on our menu?

The environment

Climate change will continue to have a significant impact on ecosystems and organisms, though they are not impacted equally. The Arctic is one of the ecosystems most vulnerable to the effects of climate change, as it is warming at least twice the rate of the global average and melting land ice sheets and glaciers contribute dramatically offsite link to sea level rise around the globe.

Some living things are able to respond to climate change; some plants are blooming earlier and some species may expand their geographic range. But these changes are happening too fast for many other plants and animals as increasing temperatures and changing precipitation patterns stress ecosystems. Some invasive or nuisance species, like lionfish and ticks, may thrive in even more places because of climate change. 

Changes are also occurring in the ocean. The ocean absorbs about 30% of the carbon dioxide that is released into the atmosphere from the burning of fossil fuels. As a result, the water is becoming more acidic, affecting marine life. Sea levels are rising due to thermal expansion, in addition to melting ice sheets and glaciers, putting coastal areas at greater risk of erosion and storm surge.

The compounding effects of climate change are leading to many changes in ecosystems. Coral reefs are vulnerable to many effects of climate change: warming waters can lead to coral bleaching, stronger hurricanes can destroy reefs, and sea level rise can cause corals to be smothered by sediment. Coral reef ecosystems are home to thousands of species, which rely on healthy coral reefs to survive.

As future leaders who will make decisions about the issues they face in their communities, the Museum of Science and Industry positioned high school-aged teens to act as advocates for building the city’s resilience to the impacts and consequences of global climate change.

Infrastructure

Physical infrastructure includes bridges, roads, ports, electrical grids, broadband internet, and other parts of our transportation and communication systems. It is often designed to be in use for years or decades, and many communities have infrastructure that was designed without future climate in mind. But even newer infrastructures can be vulnerable to climate change. 

Extreme weather events that bring heavy rains, floods, wind, snow, or temperature changes can stress existing structures and facilities. Increased temperatures require more indoor cooling, which can put stress on an energy grid. Sudden heavy rainfall can lead to flooding that shuts down highways and major business areas. 

Nearly 40% of the United States population lives in coastal counties, meaning millions of people will be impacted by sea level rise. Coastal infrastructure, such as roads, bridges, water supplies, and much more, is at risk. Sea level rise can also lead to coastal erosion and high-tide flooding. Some communities are projected to possibly end up at or below sea level by 2100 and will face decisions around managed retreat and climate adaptation. 

Many communities are not yet prepared to face climate-related threats. Even within a community, some groups are more vulnerable to these threats than others. Going forward, it is important for communities to invest in resilient infrastructure that will be able to withstand future climate risks. Researchers are studying current and future impacts of climate change on communities and can offer recommendations on best practices. Resilience education is vitally important for city planners, emergency managers, educators, communicators, and all other community members to prepare for climate change.

NOAA Sea Grant in North Carolina partnered with state and local groups to evaluate strategies for coping with inland road flooding during tropical storms and hurricanes.

What are the impacts of climate change on meteorological patterns in the Typhoon Haiyan?

The impacts of Typhoon Haiyan were more extreme because of climate change, the World Meteorological Organisation (WMO) said today. Extreme sea level rise has made coastal communities more vulnerable to the storm surges that follow extreme weather events such as Haiyan, said Jerry Lengoasa, deputy head of the WMO.

What is meteorological impact of climate change?

Rising global average temperature is associated with widespread changes in weather patterns. Scientific studies indicate that extreme weather events such as heat waves and large storms are likely to become more frequent or more intense with human-induced climate change.

What are meteorological patterns?

A weather pattern occurs when the weather stays the same for days or weeks at a time. Some common weather patterns include hot and dry weather, wet and rainy weather, and cold weather. If weather patterns go on for too long, they can lead to emergencies like heat waves, flooding, and blizzards.

What are the major patterns of climate change?

The consequences of climate change now include, among others, intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity.
