The Earth Hour 2016 report

On Saturday 19 March, Earth Hour 2016 was celebrated in a record-breaking 178 countries and territories across seven continents and aboard the International Space Station, serving as a strong visual reminder of the globe’s determination to tackle our planet’s biggest environmental challenge yet. In 2016, in recognition of the interconnected world we live in today thanks to social media and the crosscutting nature of climate change itself, Earth Hour aimed to move the movement for climate action from skylines to timelines. The movement encouraged people to not only support climate projects as in previous years, but also help in spreading the word by ‘donating their social power’ and taking a stand against climate change on their own personal landmark- their Facebook and Twitter accounts.

The Earth Hour 2015 report

Agriculture and food production are highly vulnerable to changes in climate variability, seasonal shifts, and rainfall patterns caused by climate change. Experts predict that changes in temperature, rainfall and seasonal trends will impact production of staples and crops like corn, beans, cocoa, and even coffee, which require certain conditions for cultivation. In 2015, WWF and Earth Hour teams around the world drove awareness on the impact of climate change on agriculture and how consumers, businesses and communities can each take action. From spreading awareness on consuming wisely to sustainable dinners on the night of Earth Hour (the UK, Finland and France) and creating the world’s first ever Earth Hour recipe book Planet to Plate with recipes by 52 celebrity chefs in Australia, sustainable food and agriculture was a major theme for Earth Hour 2015.
