The latest IPCC report does not mince words(直言不讳地) about the state of our planet: we must act now to achieve global change at a scale that has “no documented historical precedent(先例)” in order to avoid the climate disaster that would result from a 2 degree C rise in average global temperature. Climate change already affects the world's most helpless people including poor rural communities that depend on the land for their livings and coastal communities. Indeed, we have already seen the clear asymmetry(不对称) of suffering resulting from extreme weather events, such as hurricanes, floods, droughts, wildfires and more.

So far, advocates and politicians have tended to focus on reducing fossil fuel(矿物燃料) consumption through technology and/or policy, such as a sharp carbon tax, as climate solutions. These proposals are, of course, essential to reducing manmade carbon emissions(排放)-71 percent of which are produced by just 100 fossil fuel companies.

Yet the international focus on fossil fuels has overshadowed(使......显得不重要) the most powerful and cost-efficient carbon-capture technology the world has yet seen: forests. Recent scientific research confirms that forests and other “natural climate solutions” are absolutely essential in reducing climate change. In fact, natural climate solutions can help us achieve 37 percent of our climate target, even though they currently receive only 2.5 percent of public climate financing.

Forests' power to store carbon dioxide through the simple process of tree growth is staggering:_one tree can even store an average of about 48 pounds of carbon dioxide in one year. Recent research show undamaged forests are capable of storing the same amount of the carbon dioxide emissions of entire countries such as Peru and Colombia.

For this reason, policy makers and business leaders must create and strengthen ambitious policies to prevent deforestation, and support the sustainable management of standing forests in the fight against climate change. Protecting the world's forests ensures they can continue to provide essential functions aside from climate stability, including producing oxygen, filtering water and supporting biodiversity. Not only do all the world's people depend on forests to provide clean air, clean water，oxygen, and medicines, but 1.6 billion people rely on them directly for their livelihoods.
