Climate vs. Weather

Weather and climate are linked, but they are different things.

Weather is the day-to-day localised conditions, whereas climate is the average weather conditions over a minimum of 30 years. A change in climate will affect the day-to-day weather, but weather is not solely representative of the climate.

Global Warming vs Climate Change

The term "global warming" is misleading, as it suggests the world is warming everywhere at the same rate. This is untrue. Some areas are warming due to the growing greenhouse gas emissions, but this in fact, is only one element of the world's changing ecosystem.

Climate Change is a better term which refers to the large-scale, long-term shift in the planet's weather patterns or average temperatures.

Why is CO2 important?

Carbon Dioxide (CO2) occurs naturally in the atmosphere.
It's an important heat-trapping (greenhouse) gas that helps the planet sustain life.

But human activity has directly increased the amount in the atmosphere.
Burning fossil fuels like coal and oil or chopping down forests have added to the greenhouse gases.

The amount of Co2 in the atmosphere is the highest since records began and the rate of temperature rise since the Industrial Revolution is extremely high. As this continues it will change the climate and we will see more extreme weather events like heavy rain or heatwaves.

co2 = climate change = shifts in weather

Main causes for the rise in CO2 emissions


Electricity and heat production

In 2010 this contributed to 25% of greenhouse gas emissions. The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions/


Agriculture and Deforestation

This contributes to 24% of global greenhouse gas emissions (2010). Greenhouse gas emissions from this sector come mostly from agriculture (cultivation of crops and livestock) and deforestation.



This sector isn’t often discussed in climate change literature, however manufacturing and construction significantly contribute towards climate change. This includes emissions from the manufacture of cement, chemicals and metals.

Climate Timeline

  1. The Inconvenient Truth

    16th May, 2006

    The Inconvenient Truth is released which aims to educate citizens about global warming via a comprehensive slide show. The documentary was generally well-received politically in many parts of the world and is credited for raising further awareness of global warming internationally. The film went on to win two Academy Awards, the first ever documantary to do so. The UK Government, Welsh Assembly Government and Scottish Executive announced between January–March 2007 that copies of An Inconvenient Truth would be sent to all their secondary schools.

  2. Awful August

    16 August, 2008

    'Awful August' was so named by the Met Office because of the unsettled, extreme weather it brought to the UK. Rain soaked large swathes of Britain, which was already water-logged by earlier downpours. Parts of the UK experinced more than two inches (55-65 mm) of rainfall in 24 hours.

  3. Biggest Emitter


    China overtakes the US as the world's biggest greenhouse gas emitter - although the US remains well ahead on a per-capita basis.

  4. Population: 7 Billion

    28th October, 2011

    Human population reaches seven billion.
    Data shows concentrations of greenhouse gases are rising faster than in previous years.

  5. 400 Parts Per Million

    29th April, 2013

    Concentration of CO2 in the atmosphere has surpassed 400 parts per million (ppm) for the first time since measurements began in 1958.

  6. Deadly Heat Waves

    May, 2015

    In summer 2015, one of the deadliest heat waves in history killed more than 3,700 people in India and Pakistan.

  7. The Paris Agreement

    22nd April, 2016

    The deal unites all the world's nations in a single agreement on tackling climate change for the first time in history. Their goal, to keep global temperatures "well below" 2.0C (3.6F) above pre-industrial times and "endeavour to limit" them even more, to 1.5C.

  8. Hurricane Irma

    September, 2017

    Hurricane Irma, the strongest hurricane observed in the Atlantic since 2005 and the strongest storm on record to exist in the open Atlantic region. Irma caused widespread and catastrophic damage throughout its long lifetime, particularly in the northeastern Caribbean and the Florida Keys. It was also the most intense hurricane to strike the continental United States since Katrina in 2005.

  9. USA Scores Low


    In the first months of the Trump Administration, the USA started to take several steps backwards on climate action, especially by declaring its withdrawal from the Paris Agreement and dismantling the Clean Power Plan. Published this year, The Climate Change Performance Index (CCPI) ranks results defined by a country’s performance in four main categories. These include Green House Gas Emissions, Renewable Energy, Energy Use and Climate Policy. The 2018 Index shows The United States form the bottom five of this classification, scoring "low" or "very low" across almost all categories.
