Growing more food with less pollution. Climate change is threatening the sea ice where polar bears live. Credit: Allan Hopkins. Act when it matters most Every day more than 60 people sign up for news and alerts, to find out when their support helps most. The COVID emergency has shattered our sense of normalcy and forced us to grapple with the kind of world we want — and need — when this crisis is over. Because even with the threat of coronavirus outside our doors, we are still working to give our children a better world to live in.
This intensive and free! At Climate Reality, we work hard to create high-quality educational content like blogs, e-books, videos, and more to empower people all over the world to fight for climate solutions and stand together to drive the change we need. We are a nonprofit organization that believes there is hope in unity, and that together, we can build a safe, sustainable future.
Here are just a few ways that climate change impacts our everyday lives: Climate Change Is Bad for Our Health Climate change impacts human health in countless ways, but four are worth emphasizing here: Rising temperatures : As temperatures climb around the globe, we expect to see more heatwaves — and ever-more intense ones at that.
And certain populations are more at risk from the impacts of heatwaves than others, including the elderly, children, and the poor. Air quality : Pollution from burning fossil fuels is bad enough for the air we breathe, but many impacts of climate change also impact air quality. For instance, climate change has been linked to more wildfires.
Vector-borne diseases : Vector-borne diseases are illnesses spread by insects or arachnids like mosquitoes, fleas, mites, and ticks. As our climate becomes warmer, some insects will see their geographic ranges grow — bringing the Lyme disease and West Nile or Zika viruses they carry along with them to new regions. Extreme weather: While we go into more detail on this later, climate change has been linked to many types of extreme weather, including hurricanes and floods. Not only can these extreme weather events have immediate fatal consequences, but they can lead to major injuries and the spread of waterborne illnesses such as wound infections, dermatitis, conjunctivitis, and ear, nose and throat infections.
Healthy people need a healthy climate. So far, it sounds like the world is getting wetter, right? Not so fast! Climate Facts: Droughts and Floods Have you ever wondered why ClimateChange leads to more intense droughts, but also more flooding? Most mountain glaciers have completely melted. Skiing is now a predominantly indoor sport which takes place on giant artificial slopes. The extra heat in the ocean has caused it to expand. Combined with water from melting ice sheets, sea levels have risen by more than one metre.
Many major cities, including Hong Kong, Rio de Janeiro and Miami, are already flooded and uninhabitable. The Maldives, the Marshall Islands, Tuvalu and many other small island nations have been abandoned. Many coastal and river areas are regularly flooded , including the Nile Delta, the Rhine valley and Thailand. Winter storms are more energetic and unleash more water, causing widespread wind damage and flooding each year.
Tropical cyclones have become stronger and affect tens of millions of people every year. South-east Asian monsoons have become more intense and unpredictable, bringing either too much or too little rain to each region, affecting the lives of over three billion people.
Food and water insecurity has increased around the world, threatening the health and wellbeing of billions of people. Extreme heat and humidity in the tropics and subtropics has increased the number of days that it is impossible to work outside tenfold — slashing farm productivity. Extreme weather in temperate regions like Europe has made food production highly unpredictable. Arctic sea ice extent both affects and is affected by global climate change. An interactive exploration of how global warming is affecting sea ice, glaciers and continental ice sheets worldwide.
Below are some of the impacts that are currently visible throughout the U. Global Change Research Program :. Heat waves, heavy downpours and sea level rise pose growing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries and ecosystems will be increasingly compromised. Many states and cities are beginning to incorporate climate change into their planning. Changes in the timing of streamflow reduce water supplies for competing demands.
Sea level rise, erosion, inundation, risks to infrastructure and increasing ocean acidity pose major threats. Increasing wildfire, insect outbreaks and tree diseases are causing widespread tree die-off.
Extreme heat will affect health, energy, agriculture and more. Decreased water availability will have economic and environmental impacts. Extreme heat, heavy downpours and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more.
Climate change will also exacerbate a range of risks to the Great Lakes. Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.
Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.
