CERESMIP: a climate modeling protocol to investigate recent trends in the Earth's Energy Imbalance
2024-02-19 (or before) in FrontiersThe Clouds and the Earth's Radiant Energy System (CERES) project has now produced over two decades of observed data on the Earth’s Energy Imbalance (EEI) and has revealed substantive trends in both the reflected shortwave and outgoing longwave top-of-atmosphere radiation components. Available climate model simulations suggest that these trends are incompatible with purely internal variability, but that the full magnitude and breakdown of the trends are outside of the model ranges. Unfortunately, the Coupled Model Intercomparison Project (Phase 6) (CMIP6) protocol only uses observed forcings to 2014 (and Shared Socioeconomi...

Global Carbon Budget 2023
2023-12-05 (or before) in Earth System Science DataAbstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere in a changing climate is critical to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe and synthesize data sets and methodology to quantify the five major components of the global carbon budget and their uncertainties. Fossil CO2 emissions (EFOS) are based on energy statistics and cement production data, while emissions from land-use change (ELUC), mainly deforestation, are based on la...

Heat stored in the Earth system 1960–2020: where does the energy go?
2023-08-14 (or before) in Earth System Science DataAbstract. The Earth climate system is out of energy balance, and heat has accumulated continuously over the past decades, warming the ocean, the land, the cryosphere, and the atmosphere. According to the Sixth Assessment Report by Working Group I of the Intergovernmental Panel on Climate Change, this planetary warming over multiple decades is human-driven and results in unprecedented and committed changes to the Earth system, with adverse impacts for ecosystems and human systems. The Earth heat inventory provides a measure of the Earth energy imbalance (EEI) and allows for quantifying how much heat has accumulated in the Ea...

Indicators of Global Climate Change 2022: annual update of large-scale indicators of the state of the climate system and human influence
2023-06-08 (or before) in Earth System Science DataAbstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC), including the first global stocktake under the Paris Agreement that will conclude at COP28 in December 2023. Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential...

New study shows Earth energy imbalance
2023-04-19 in World Meteorological OrganizationThe Earth climate system is out of energy balance as a result of human-induced climate change. Heat has accumulated continuously over the past decades, warming the ocean, the land, the cryosphere, and the atmosphere.

Heat stored in the Earth system: where does the energy go?
2021-08-08 (or before) in Earth System Science Data<p><strong class="journal-contentHeaderColor">Abstract.</strong> Human-induced atmospheric composition changes cause a radiative imbalance at the top of the atmosphere which is driving global warming. This Earth energy imbalance (EEI) is the most critical number defining the prospects for continued global warming and climate change. Understanding the heat gain of the Earth system – and particularly how much and where the heat is distributed – is fundamental to understanding how this affects warming ocean, atmosphere and land; rising surface temperature; sea level; and loss of grounded and floating i...

Anthropogenic forcing and response yield observed positive trend in Earth’s energy imbalance - Nature Communications
2021-07-28 in NatureSatellite observations reveal a significant positive trend in Earth’s energy imbalance, but the contributing drivers have yet to be understood. Here, the authors show that it is exceptionally unlikely that this trend can be explained by internal variability; instead, anthropogenic forcing and feedbacks cause the trend.

The amount of heat the Earth traps has doubled since 2005, NASA says - The Washington Post
2021-06-16 in The Washington PostThe amount of heat the Earth traps has roughly doubled since 2005, according to new research from NASA and NOAA. The additional energy is equivalent to four detonations per second of the atomic bomb dropped on Hiroshima.
