We assess climate impacts of global warming using ongoing observations and paleoclimate data. We use Earth’s measured energy imbalance, paleoclimate data, and simple representations of the global carbon cycle and temperature to define emission reductions needed to stabilize climate and avoid potentially disastrous impacts on today’s young people, future generations, and nature. A cumulative industrial-era limit of ∼500 GtC fossil fuel emissions and 100 GtC storage in the biosphere and soil… Expand
Reducing climate risks with fast and complete energy transitions: applying the precautionary principle to the Paris agreement
Averting the climate catastrophe requires the transformation of the energy system. A wide range of energy transition pathways are being explored in literature, which limit peak heating during thisExpand
Young People's Burden: Requirement of Negative CO2 Emissions
Abstract. Global temperature is a fundamental climate metric highly correlated with sea level, which implies that keeping shorelines near their present location requires keeping global temperatureExpand
How Should a Global Carbon Budget be Estimated?
The Intergovernmental Panel on Climate Change (IPCC), the authority for estimating a carbon budget for keeping to the Paris Agreement’s 1.5—2°C target for limiting global warming, has indicated aExpand

Global warming is unequivocal and almost certainly caused by recent human activities that have increased the greenhouse gas (GHG) emissions. Emissions reductions of carbon dioxide and cumulativeExpand
Likelihood of climate change pathways under uncertainty on fossil fuel resource availability
Uncertainties concerning fossil fuel resource availability have traditionally been deemphasized in climate change research as global baseline emission scenarios (i.e., scenarios that do not considerExpand

The global warming potential of methane (CH4) is about 30 times stronger than that of carbon dioxide (CO2) over a century timescale. Methane emission is hypothesized to have contributed to globalExpand
Sustained climate warming drives declining marine biological productivity
In a coupled climate simulation to the year 2300, the westerly winds strengthen and shift poleward, surface waters warm, and sea ice disappears, leading to intense nutrient trapping in the Southern Ocean, which drives a global-scale nutrient redistribution, with net transfer to the deep ocean.

Is there an engineering approach for the transition to a sustainable hydrogen economy
In the paper “Assessing Dangerous Climate Change: Required Reduction of Carbon Emissions to Protect Young People, Future Generations and Nature” published in PLOS One, 3 December 2013, James HansenExpand
The role of enhanced rock weathering deployment with agriculture in limiting future warming and protecting coral reefs
Meeting the net-zero carbon emissions commitments of major economies by mid-century requires large-scale deployment of negative emission technologies (NETs). Terrestrial enhanced rock weathering onExpand
Should we geoengineer larger ice caps
Abstract The climate of Earth is susceptible to catastrophes that could threaten the longevity of human civilization. Geoengineering to reduce incoming solar radiation has been suggested as a way toExpand


Implications of “peak oil” for atmospheric CO2 and climate
[1] Unconstrained CO2 emission from fossil fuel burning has been the dominant cause of observed anthropogenic global warming. The amounts of “proven” and potential fossil fuel reserves are uncertainExpand
Warming caused by cumulative carbon emissions towards the trillionth tonne
It is found that the peak warming caused by a given cumulative carbon dioxide emission is better constrained than the warming response to a stabilization scenario, and policy targets based on limiting cumulative emissions of carbon dioxide are likely to be more robust to scientific uncertainty than emission-rate or concentration targets. Expand
Persistence of climate changes due to a range of greenhouse gases
It is shown that the warming due to non-CO2 greenhouse gases, although not irreversible, persists notably longer than the anthropogenic changes in the greenhouse gas concentrations themselves, which should not be expected to decrease climate change impacts as rapidly as the gas or aerosol lifetime.

Geoengineering the Climate: Science, Governance and Uncertainty
Geoengineering, or the deliberate large-scale manipulation of the planetary environment to counteract anthropogenic climate change, has been suggested as a new potential tool for addressing climateExpand
Greenhouse-gas emission targets for limiting global warming to 2 °C
A comprehensive probabilistic analysis aimed at quantifying GHG emission budgets for the 2000–50 period that would limit warming throughout the twenty-first century to below 2 °C, based on a combination of published distributions of climate system properties and observational constraints is provided.

Climate change and trace gases
Only intense simultaneous efforts to slow CO2 emissions and reduce non-CO2 forcings can keep climate within or near the range of the past million years. Expand
Lifetime of Anthropogenic Climate Change: Millennial Time Scales of Potential CO2 and Surface Temperature Perturbations
Abstract Multimillennial simulations with a fully coupled climate–carbon cycle model are examined to assess the persistence of the climatic impacts of anthropogenic CO2 emissions. It is found thatExpand
Enhanced chemistry-climate feedbacks in past greenhouse worlds
Results from a series of three-dimensional Earth system modeling simulations indicate that the greenhouse worlds of the early Eocene and late Cretaceous maintained high concentrations of methane, tropospheric ozone, and nitrous oxide, and point to chemistry-climate feedbacks as possible amplifiers of climate sensitivity in the Anthropocene.

Methane hydrate stability and anthropogenic climate change
Abstract. Methane frozen into hydrate makes up a large reservoir of potentially volatile carbon below the sea floor and associated with permafrost soils. This reservoir intuitively seems precarious,Expand
The proportionality of global warming to cumulative carbon emissions
It is shown that the carbon–climate response (CCR), defined as the ratio of temperature change to cumulative carbon emissions, is approximately independent of both the atmospheric CO2 concentration and its rate of change on these timescales. Expand
