6 MYTHS ABOUT CLIMATE CHANGE
With the climate crisis becoming a hot topic in mainstream media - there's a lot of confusion around what climate change actually is. That's why we've tried to clear up some of the most frequently heard myths, so that you can tell fiction from fact!
MYTH 1: THE EARTH’S CLIMATE HAS ALWAYS CHANGED
Over the course of the Earth’s 4.5-billion-year history, the climate has changed a lot. This is true. But the rapid warming we’re seeing now can't be explained by natural cycles of warming and cooling. The kind of changes that would normally happen over hundreds of thousands of years are happening in decades. Global temperatures are now at their highest since records began. In fact, 17 of the 18 warmest years on record have all taken place since 2001.
This much faster warming corresponds with levels of carbon dioxide in the atmosphere, which have been increasing since the industrial revolution. So, when people talk about climate change today, they mean anthropogenic (man-made) climate change. This is the warming of Earth’s average temperature as a result of human activity, such as burning coal, oil and gas to produce energy to fuel our homes and transport and cutting down trees to produce the food we eat.
MYTH 2: PLANTS NEED CARBON DIOXIDE
Plants do need carbon dioxide (CO2) to live. Plants and forests remove and store away huge amounts of carbon dioxide from the atmosphere each year. But the problem is, there’s only so much carbon dioxide they can absorb and this amount is getting less, as more and more forests are cut down across the world, largely to produce our food.
Let’s be clear, CO2 itself does not cause problems. It's part of the natural global ecosystem. The problem is the quantity of CO2 that’s being produced by us as humans; there hasn’t been this level of CO2 in the atmosphere for 800,000 years.
MYTH 3: GLOBAL WARMING ISN'T REAL AS IT'S STILL COLD
Global warming is causing the Earth’s average surface temperature to increase. This is not only making heatwaves and droughts more likely but it’s also causing changes to our natural climate systems. These changes are making extreme weather events more likely and more severe. For example, hurricanes and storms are becoming more intense, moving slower and taking longer to die down.
Because of where we are, the UK & Ireland are likely to get more rain and wind as a result of climate change while New York will see more snow.
MYTH 4: CLIMATE CHANGE IS A FUTURE PROBLEM
This is no longer an excuse not to act on climate change and push the burden onto future generations. Last year, the world’s leading climate scientists warned we only have 12 years to limit global warming to a maximum of 1.5C and avoid climate breakdown.
We’re already seeing the devastating effects of climate change on global food supplies, increasing migration, conflict, disease and global instability, and this will only get worse if we don’t act now. Man-made climate change is the biggest environmental crisis of our time. It threatens the future of the planet that we depend on for our survival and we're the last generation that can do something about it.
MYTH 5: RENEWABLE ENERGY IS JUST A MONEY-MAKING SCHEME
It's a commonly-held belief that renewable energy is expensive, but this simply isn’t true! Solar power and onshore wind are the cheapest ways of generating electricity; meaning the energy they produce is cheaper than using nuclear, gas and fossil fuels.
The cost of renewables has fallen faster than anyone could have predicted. And yet the government are still backing dirty fossil fuels. Did you know the UK has the biggest fossil fuel subsidies in the EU? That’s right, they spend an eye-watering €12bn a year supporting dirty fossil fuels.
MYTH 6: RENEWABLE ENERGY CAN ONLY WORK WHEN IT'S NOT CLOUDY OR WINDY
Industry is developing new techniques for storing electricity and managing demand at peak times meaning that even if the sun isn't shining or it’s not blowing a gale, it’s still possible to rely on renewable energy sources. The majority of UK homes get their electricity from the National Grid. When you switch to a clean supplier, they guarantee that for every unit of electricity you take out of the Grid, they’ll put the same amount of clean energy back in, helping to clean up our energy supply.
