11 FACTS YOU NEED TO KNOW ABOUT CLIMATE CHANGE
We’re already seeing the effects of human-caused climate change — but nature can help.
We’re already seeing the effects of climate change, but thankfully, the planet is equipped with a powerful tool for stabilizing the climate: nature itself. Protecting nature today means a better planet for future generations. Share these facts about climate change and help make a difference:

416 parts per million 1
The concentration of carbon dioxide (CO2) in our atmosphere, as of May 2020, is the highest it has been in human history. 2

2019 was the second warmest year on record
NASA data show that average global temperatures in 2019 were 1.8 degrees F (0.98 degrees C) warmer than the 20th-century average. 3 In fact, the five warmest years in the 1880–2019 record have all occurred since 2015. 4

11% of emissions
Eleven per cent of all global greenhouse gas emissions caused by humans are due to deforestation 5 — comparable to the emissions from all of the passenger vehicles on the planet.

Nature is an untapped solution
Tropical forests are incredibly effective at storing carbon, providing at least a third of the mitigation action needed 7 to prevent the worst climate change scenarios. Yet nature-based solutions receive only 3% of all climate funding. 8

Fight climate change, improve livelihoods — naturally
Natural climate solutions such as restoring degraded forests could create as many as 39 jobs per million dollars spent — that's a job-creation rate more than six times higher than the oil and gas industry. 9

10x the return on investment
Roughly 3.2 billion people are currently impacted by land degradation worldwide. Restoration is critical and cost-effective. Every US$ 1 invested in restoration generates, on average, 10x that amount in benefits. 10

800 million people
Eleven per cent of the world’s population is currently vulnerable to climate change impacts 11 such as droughts, floods, heatwaves, extreme weather events and sea-level rise.

Coastal ‘blue carbon' ecosystems are critical
Just 0.7% of the world’s forests are coastal mangroves 12, yet they store up to 10 times as much carbon per hectare as tropical forests. 13, 14, 15

800,000 hectares lost every year 15
If we continue to lose mangroves at this rate, they may disappear within the next century. This loss removes an important buffer from extreme weather for coastal communities and releases immense amounts of carbon dioxide into the atmosphere.

Save nature. It’s cheaper
Conserving ecosystems is often more cost-effective than human-made interventions. In the Maldives, preserving the natural coral reef is four times cheaper than building a sea wall for coastal protection, even after 10 years of maintenance costs. 16

189 nations on board
189 countries have ratified the 2015 Paris Agreement 17, agreeing to limit global warming and adapt to climate change, partly by protecting nature.
BONUS FACT

Price tag: US$ 140 billion per year 18
This is what it would take to make the changes humanity needs to adapt to a warming world. It may sound like a lot, but it’s less than 0.2% of global GDP. 19 And the cost will only increase the longer we take to act ambitiously.
