2. Glaciers are melting, sea levels are rising,
cloud forests are dying, and wildlife is
scrambling to keep pace. It's becoming
clear that humans have caused most of
the past century's warming by releasing
heat-trapping gases as we power our
modern lives. Called greenhouse gases,
their levels are higher now than in the
last 650,000 years.
We call the result global warming, but it is causing a set of
changes to the Earth's climate, or long-term weather patterns,
that varies from place to place. As the Earth spins each day, the
new heat swirls with it, picking up moisture over the oceans,
rising here, settling there. It's changing the rhythms of climate
that all living things have come to rely upon.
What is global warming?

3. So how do we solve the problem? How do we begin the process of
reversing global warming? The only way we know how is to draw down,
to avoid putting greenhouse gases up and to pull down what's already
there. Given the current situation, it sounds impossible, but humanity
already knows what to do. We have real, workable technologies and
practices that can achieve drawdown. And it's already happening. What
we need is to accelerate implementation and to change the discourse
from one of fear and confusion, which only leads to apathy, to one of
understanding and possibility, and, therefore, opportunity.
There are solutions that are viable, scalable and financially feasible. And
they do one or more of three things: replace existing fossil fuel-based
energy generation with clean, renewable sources; reduce consumption
through technological efficiency and behavior change; and to
biosequester* carbon in our plants' biomass and soil through a process
we all learn in grade school, the magic of photosynthesis.
*Biosequestration is the capture and storage of the atmospheric
greenhouse gas carbon dioxide by biological processes
Stopping global warming

4. When we think about climate solutions, we often think
about electricity generation. We think of renewable energy
as the most important set of solutions, and they are
incredibly important. But that is not the only solution. How
we manage land is also very important. Protecting forests
and wetlands safeguards, expands and creates new carbon
sinks that directly drawdown carbon. This is how
drawdown can happen. And when we take food and land
management together. This fundamentally shifts
traditional thinking on climate solutions.
And tropical forests tell their own story. Protecting
currently degraded land in the tropics and allowing
natural regeneration to occur is the number five solution
to reversing global warming. We can think of trees as
giant sticks of carbon. This is drawdown in action every
year, as carbon is removed from the atmosphere through
photosynthesis, which converts carbon dioxide to plants'
biomass and soil organic carbon. And we need to rethink
how we produce our food to make it more regenerative.
There are many ways to do this, and we researched over
13 of them, but these aren't new ways of producing
food.

5. The climate impact of food may come as a surprise to many people, but what the results show
is that the decisions we make every day about the food we produce, purchase and consume are
perhaps the most important contributions every individual can make to reversing global
warming.
The way we harvest our food is
increasingly displaced by modern
agriculture, which promotes
tillage, monocropping and the use
of synthetic fertilizers and
pesticides which degrade the land
and turn it into a net emitter of
greenhouse gases. Regenerative
agriculture, on the other hand,
restores soil health and
productivity, increases yield,
improves water retention, benefits
smallholder farmers and large
farming operations alike and
brings carbon back to the land.

6. Moreover, approximately a third of all food produced is not eaten, and wasted food emits an astounding
eight percent of global greenhouse gases. We need to look where across the supply chain these losses and
wastage occurs. In low-income countries, after food leaves the farm, most food is wasted early in the supply
chain due to infrastructure and storage challenges. Food is not wasted by consumers in low-income
countries which struggle to feed their population. In the developed world, instead, after food leaves the
farm, most food is wasted at the end of the supply chain by markets and consumers, and wasted food ends
up in the landfill where it emits methane as it decomposes. This is a consumer choice problem. It's not a
technology issue. Preventing food waste from the beginning is one of the best solutions.

7. But here's the interesting thing.
When we look at the food system
as a whole and we implement all
the production solutions like
regenerative agriculture, and we
adopt a plant-rich diet, and we
reduce food waste, our research
shows that we would produce
enough food on current farmland
to feed the world's growing
population a healthy, nutrient-rich
diet now until 2050 and beyond.
That means we don't need to cut
down forests for food production.
The solutions to reversing global
warming are the same solutions
to food insecurity.
Regenerative agriculture is an approach to food and farming systems
which aims to regenerate topsoil, increase biodiversity, improve water
cycles, enhance ecosystem services, support biosequestration, increase
resilience to climate fluctuation, and strengthen the health and vitality
of farm soil, by recycling as much farm waste as possible, as well as
adding compost material from outside the farm.
