The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change.
IPCC Sixth Assessment Report (AR6): "Climate Change 2023: Synthesis Report" - March 20, 2023
In 2018, the IPCC highlighted the unprecedented scale of the challenge required to keep warming to 1.5°C. Five years later, that challenge has become even greater due to a continued increase in greenhouse gas emissions. The pace and scale of what has been done so far, and current plans, are insufficient to tackle climate change. Fortunately, there are multiple, feasible, and effective options to reduce greenhouse gas emissions and adapt to human-caused climate change, and they are available now.
IPCC Sixth Assessment Report (AR6): Working Group III (WGIII) Report: "Climate Change 2022: Mitigation of Climate Change" (April 2022)
In 2010–2019 average annual global greenhouse gas emissions were at their highest levels in human history, but the rate of growth has slowed. Without immediate and deep emissions reductions across all sectors, limiting global warming to 1.5°C is beyond reach. However, there is increasing evidence of climate action. Since 2010, there have been sustained decreases of up to 85% in the costs of solar and wind energy, and batteries. An increasing range of policies and laws have enhanced energy efficiency, reduced rates of deforestation and accelerated the deployment of renewable energy. We have options in all sectors to at least halve emissions by 2030 and the next few years are critical.
IPCC Sixth Assessment Report (AR6): Working Group II (WGII) Report: "Climate Change 2022: Impacts, Adaptation and Vulnerability" (February 2022)
Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit. The world faces unavoidable multiple climate hazards over the next two decades with global warming of 1.5°C (2.7°F). Even temporarily exceeding this warming level will result in additional severe impacts, some of which will be irreversible. Risks for society will increase, including to infrastructure and low-lying coastal settlements.
IPCC Sixth Assessment Report (AR6): Working Group I (WGI) Report: "Climate Change 2021: The Physical Science Basis" (August 2021)
Scientists are observing changes in the Earth’s climate in every region and across the whole climate system. Many of the changes observed in the climate are unprecedented in thousands, if not hundreds of thousands of years, and some of the changes already set in motion—such as continued sea level rise—are irreversible over hundreds to thousands of years. However, strong and sustained reductions in emissions of carbon dioxide (CO2) and other greenhouse gases would limit climate change.
Special Report on the Ocean and Cryosphere in a Changing Climate (September 2019)
The IPCC Special Report on the Ocean and Cryosphere in a Changing Climate highlights the urgency of prioritizing timely, ambitious and coordinated action to address unprecedented and enduring changes in the ocean and cryosphere. This Special Report, approved on September 24, 2019, by the 195 IPCC member governments, provides new evidence for the benefits of limiting global warming to the lowest possible level—in line with the goal that governments set themselves in the 2015 Paris Agreement. Urgently reducing greenhouse gas emissions limits the scale of ocean and cryosphere changes so that the ecosystems and the livelihoods that depend on them can be preserved.
Special Report on Climate Change and Land (August 2019)
According to the IPCC Special Report on Climate Change and Land, land is already under growing human pressure and climate change is adding to these pressures. At the same time, keeping global warming to well below 2ºC can be achieved only by reducing greenhouse gas emissions from all sectors including land and food. The report analyzes climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems.
Global Warming of 1.5°C (October 2018)
An IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
The Earth Observatory's mission is to share with the public the images, stories, and discoveries about climate and the environment that emerge from NASA research, including its satellite missions, in-the-field research, and climate models.
Climate 365 was a yearlong effort in 2013 to highlight NASA's ongoing monitoring of Earth's climate.
Research at the NASA Goddard Institute for Space Studies (GISS) emphasizes a broad study of global change, which is an interdisciplinary initiative addressing natural and man-made changes in our environment that occur on various time scales—from one-time forcings such as volcanic explosions, to seasonal and annual effects such as El Niño, and on up to the millennia of ice ages—and that affect the habitability of our planet.
Climate.gov is a source of timely and authoritative scientific data and information about climate. Climate.gov's goals are to promote public understanding of climate science and climate-related events, to make NOAA data products and services easy to access and use, to provide climate-related support to the private sector and the Nation's economy, and to serve people making climate-related decisions with tools and resources that help them answer specific questions.
The U.S. Climate Resilience Toolkit provides scientific tools, information, and expertise to help people manage their climate-related risks and opportunities, and improve their resilience to extreme events. The site is designed to serve interested citizens, communities, businesses, resource managers, planners, and policy leaders at all levels of government.

This number will initially be answered by an automated attendant, from which one can opt to access a name directory, listen to recorded information about the park (e.g., directions to the park; visitor center hours of operation; fire danger information; wildlife updates; ranger-led programs; seasonal events; etc.), or speak with a ranger. Please note that if you are calling between 4:30 pm and 10 am, park staff may not be available to answer your call.
