The leading cause of climate change and global temperature increases
Using data from the past 50 years. A clear correlation can be seen between the increase in global greenhouse gas emissions globally and an increase in average global temperature, which will only be amplified into the future as populations grow if action is not taken to put a stop to it.
The clearest trend is evident in the temperature records which show a mean temperature increase of 0.7°C between 1890 and 2008. The increase was 0.4°C during the period 1980-2008.
In more recent years, another significant issue has emerged. Ocean Acidification will have harmful effects on marine organisms and has the potential to disrupt global marine ecosystems. For more information see the Marine Institute's report External linkOcean Acidification: An Emerging Threat to our Marine Environment.
Climate change impacts are projected to increase in the coming decades and during the rest of this century. Uncertainties remain in relation to the scale and extent of these impacts, particularly during the second half of the century. The greatest uncertainly lies in how effective global actions will be in reducing greenhouse gas emissions.
Predicted adverse impacts include:
One 2017 study ranked 148 individual actions on climate change according to their impact.
Going car-free was the number-one most effective action an individual could take.
Cars are more polluting compared to other means of transportation like walking, biking or using public transport.
Consider making some or all of these small changes. Together, they can really add up.
After fossil fuels, the food industry – and in particular the meat and dairy sector – is one of the most important contributors to climate change.
You don’t have to go vegetarian or vegan to make a difference: cut down gradually and become a ‘flexitarian’.
By reducing your consumption of animal protein by half, you can cut your diet's carbon footprint by more than 40%.
Although it’s important to take action to reduce our individual carbon footprints, changing the larger system is where we have the greatest opportunity to reduce emissions.
Vote for leaders at all levels of government who take climate change seriously.
They should commit to setting science-based targets to reduce harmful carbon emissions, implementing clear plans to reach those targets, adapting to climate change and shifting to a clean-energy economy.
