OUR GLOBAL CHALLENGE
Climate Change is the defining issue of our time and we are at a defining moment.
Without drastic action today, adapting to these impacts in the future will be more difficult and costly.
The greatest threat humanity has ever faced
"The climate crisis has already been solved. We already have all the facts and solutions. All we have to do is to wake up and change." GRETA THUNBERG
"With science at its core and our transcendent moral obligation to the rest of life at its heart, the Half-Earth Project is working to conserve half the land and sea to safeguard the bulk of biodiversity, including ourselves." EDWARD O. WILSON
"Scientific evidence for warming of the climate system is unequivocal"
Intergovernmental Panel on Climate Change
The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Most of the warming occurred in the past 35 years.

The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost an average of 286 billion tons of ice per year between 1993 and 2016, while Antarctica lost about 127 billion tons of ice per year during the same time period. The rate of Antarctica ice mass loss has tripled in the last decade.
Global sea level rose about 8 inches (0,2 meters) in the last century. The rate in the last two decades, however, is nearly double that of the last century and is accelerating slightly every year.
The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of intense rainfall events.
Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30%. This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year.
The Earth’s life support system is failing. Nearly everywhere, the various forms of non-human life are in decline. This ongoing decline endangers economies, livelihoods, food security, and the quality of life of people everywhere. But at the same time, there is considerable room for hope, based on many solutions with proven track records.
"The UN has prioritized the following action portfolios, which are recognized as having high potential to curb greenhouse gas emissions and increased global action on adaptation and resilience."
Mobilizing public and private sources of finance to drive decarbonization of all priority sectors and advance resilience.
Accelerating the shift away from fossil fuels and towards renewable energy, as well as making significant gains in energy efficiency.
Transforming industries such as Oil and Gas, Steel, Cement, Chemicals and Information Technology.
Reducing emissions, increasing sink capacity and enhancing resilience within and across forestry, agriculture, oceans and food systems, including through biodiversity conservation, leveraging supply chains and technology.
Advancing mitigation and resilience at urban and local levels, with a focus on new commitments on low-emission buildings, mass transport and urban infrastructure; and resilience for the urban poor.
Advancing global efforts to address and manage the impacts and risks of climate change, particularly in those communities and nations most vulnerable.
Generate momentum for ambitious Nationally Determined Contributions (NDCs) and long-term strategies to achieve the goals of the Paris Agreement.
To mobilize people worldwide to take action on climate change and ensure that young people are integrated and represented across all aspects of the Summit, including the six transformational areas.
Advance commitments in areas that affect people’s well-being, such as reducing air pollution, generating decent jobs, and strengthening climate adaptation strategies and protect workers and vulnerable groups.
