The global climate crisis poses new risks to humanity, and with them, new challenges to the practices of professional astronomy. Avoiding the more catastrophic consequences of global warming by more than 1.5 degrees requires an immediate reduction of greenhouse gas emissions. According to the 2018 United Nations Intergovernmental Panel report, this will necessitate a 45% reduction of emissions by 2030 and net-zero emissions by 2050. Efforts are required at all levels, from the individual to the… 

Pathways to Sustainable Planetary Science

Climate change is a major impending threat to the future of humanity. According to the International Panel on Climate Change (IPCC), our emissions are estimated to have caused 0.8 deg C-1.2 deg C of

The imperative to reduce carbon emissions in astronomy

For astronomers to make a significant contribution to the reduction of climate change-inducing greenhouse gas emissions, we first must quantify the sources of our emissions and review the most

The carbon footprint of IRAP

We present an assessment of the greenhouse gases emissions of the Institute for Research in Astrophysics and Planetology (IRAP), located in Toulouse (France). It was performed following the

Estimating carbon emissions at CFHT: a first step toward a more sustainable observatory

Abstract. As the crisis of climate change affects more people every year and leads to more severe weather patterns with unprecedented socio-economical consequence, all actors on the planet need to

Estimate of the carbon footprint of astronomical research infrastructures

The carbon footprint of astronomical research is an increasingly topical issue with first estimates of research institute and national community footprints having recently been published. As these

An astronomical institute’s perspective on meeting the challenges of the climate crisis

Analysing greenhouse gas emissions of an astronomical institute is a first step to reducing its environmental impact. Here, we break down the emissions of the Max Planck Institute for Astronomy in

The on-line travel footprint calculator enables us to compute the travel footprint of a large set of travels and can help identify a meeting place that minimizes the overall travel footprint for aLarge set of possible city hosts, e.g. cities with large airports.

Using the Climate App to learn about Planetary Habitability and Climate Change

Simple climate models have been around for more than a century but have recently come back into fashion: they are useful for explaining global warming and the habitability of extrasolar planets. The

The carbon footprint of large astronomy meetings

The annual meeting of the European Astronomical Society took place in Lyon, France, in 2019, but in 2020 it was held online only due the COVID-19 pandemic. The carbon footprint of the virtual meeting

Broad threat to humanity from cumulative climate hazards intensified by greenhouse gas emissions

The ongoing emission of greenhouse gases (GHGs) is triggering changes in many climate hazards that can impact humanity. We found traceable evidence for 467 pathways by which human health, water,

The human imperative of stabilizing global climate change at 1.5°C

The climate change–impact literature is reviewed, expanding on the recent report of the Intergovernmental Panel on Climate Change, and it is argued that impacts accelerating as a function of distance from the optimal temperature for an organism or an ecosystem process is a consequence of impacts accelerating.

Twentieth-century hydroclimate changes consistent with human influence

It is shown that three distinct periods are identifiable in climate models, observations and reconstructions during the twentieth century: in recent decades (1981 to present), the signal of greenhouse gas forcing is present but not yet detectable at high confidence, and in the first half of the century (1900–1949), a signal of climate change is robustly detectable.

How Much More Global Warming and Sea Level Rise?

Two global coupled climate models show that even if the concentrations of greenhouse gases in the atmosphere had been stabilized in the year 2000, we are already committed to further global warming

Atmospheric change as a driver of change in the Canadian boreal zone1

Global anthropogenic emissions of greenhouse gases and hazardous air pollutants have produced broad yet regionally disparate changes in climatic conditions and pollutant deposition in the Canadian

Importance of the pre-industrial baseline for likelihood of exceeding Paris goals

During the Paris conference in 2015, nations of the world strengthened the United Nations Framework Convention on Climate Change by agreeing to holding ‘the increase in the global average temperature

Carbon emissions of infrastructure development.

The carbon footprint of the existing global infrastructure stock in 2008, assuming current technologies, is estimated to be 122 (-20/+15) Gt CO2, which corresponds to about 35-60% of the remaining carbon budget available until 2050 if the average temperature increase is to be limited to 2 °C, and could thus compromise the2 °C target.

The travel-related carbon dioxide emissions of atmospheric researchers

Most atmospheric scientists agree that greenhouse gas emissions have already caused significant changes to the global climate system and that these changes will accelerate in the near future. At the

The climate mitigation gap: education and government recommendations miss the most effective individual actions

In their comment piece, Laycock and Lam (Environ. Res. Lett. 13 068001) focused on the importance for reducing emissions of actions beyond individual choices and overconsumption, and raise the issue
