Leading experts to investigate climate impacts of a hydrogen economy in new research project

Published 4.9.2024

Pulling together experts on hydrogen from 12 institutions throughout Europe, HYway, a new research project funded by the European Union sets out to provide an understanding of the climate and environmental risks and co-benefits of a hydrogen economy – and to advise on options for addressing those risks.

Alternative aviation fuels offer limited mitigation potential

Published 24.6.2024

The use of alternative fuels could be one way for the aviation sector to reduce its emissions. A new study of fuel use in domestic flights in Norway shows some mitigation potential for alternative fuels, but warns that these alternatives are neither emission-free nor climate-neutral.

The turbulent future brings a breath of fresh air

Published 28.6.2023

In the future, an increase in turbulence will alleviate the intensity of near-surface air pollution, according to a new paper by CICERO researchers published in Nature Communications. The findings bring a positive message showing the added benefits of mitigation.

In flames: Air pollution and human health

Published 2.12.2022

While air pollution from PM2.5-emissions have been reduced in Europe and North America, air pollution from wildfires is increasing. With climate change, we will see more wildfires, risking that the impacts of the efforts that have been made to mitigate air pollution and related negative health effects could be diminished.

Take climate-changing aerosols seriously

Published 22.11.2022

The dangerous impacts of aerosol changes on vulnerable regions should have been a priority at COP27 after climate policymakers agreed a breakthrough deal to support these parts of the world, scientists have claimed.

Aviation needs bolder approaches to climate change than carbon offsets and cleaner fuels

Published 22.9.2022

The aviation industry’s response to climate change relies mainly on cleaner fuels and carbon offsetting. Government and industry must experiment with other approaches to bring the climate impact of aviation closer to zero, argues researchers in a Nature commentary.

Aviation contributes 3.5% to the human-made drivers of climate change, a new study shows

Published 2.9.2020

Aviation accounts for 3.5% of the human-made climate impact. Two-thirds of this impact are caused by emissions other than co₂, a new study shows.

How much carbon dioxide can we emit?

Published 16.3.2017

COMMENTARY: Despite the complexity of the climate system, there is a rather simple relationship between the long-term temperature increase and the total amount of carbon dioxide emitted. Why, then, is there no clear answer to how much we can emit?

EPIC - Extreme Precipitation In Cleaner air

In EPIC we are investigating a possible link between changes in air pollution and a trend towards more hazardous extreme precipitation. Our overall goal is to increase our understanding of what controls extreme precipitation and reduce the uncertainty in estimates of future extremes. At this stage of our project, we are analyzing observational data and running cloud models to investigate how heavy precipitation reacts to our particle emissions.

UTRICS: Understanding Temporal aerosol Radiative forcing - Implications for Climate Sensitivity and future warming

Global temperatures are rising due to the accumulation of greenhouse gases in the atmosphere. In addition to increasing greenhouse gas emissions, human activity has changed the composition of particles in the atmosphere. These have masked some of the warming caused by the greenhouse gases. How large is this cooling effect, and how has it changed over time?

ACCEPT: Aerosols, Cloud Changes and Energy transport into the Polar domain: The role of feedbacks to the local climate response

The Arctic is warming more than twice as fast as the rest of the world, with dramatically decreasing trends in sea-ice and snow cover (AMAP,2017). This ‘Arctic amplification’ of global warming is a feature of human-made climate change, but its causes and consequences are not fully understood.

AVIATE: How can aviation contribute to a low-carbon society?

The AVIATE (Aviation in a low-carbon society) project will provide better understanding of the climate impact of aviation, both for Norway and globally, and explore options for reducing that impact.

CONSTRAIN

Predicting how the climate will change over the next 20-50 years, as well as defining emissions pathways to keep the world on track, requires a better understanding of how several human and natural factors will affect the climate in coming decades. These include how atmospheric aerosols affect the Earth’s radiation budget, and the roles of clouds and oceans in driving climate change.

COP30: Climate Effect of Black Carbon and Methane in the Arctic. Scientific Revisions, Policy Decisions

Black carbon (BC) and other short-lived climate forcers emitted within the Arctic and at lower latitudes are making a significant contribution to warming and have been a subject of study in recent years by Arctic Monitoring and Assessment Programme (AMAP). How the contribution of BC to Arctic climate change is likely to evolve in future is unclear, both due to uncertainties in future emission scenarios and given the complexity of the climate system and of the effects of different atmospheric pollutants, many of which are co-emitted.
