Why we may be able to save the Greenland ice sheet

Dr Teodóra Pados

Studies of ice melt in the Arctic suggest that world may have a fighting chance of preventing huge sea level changes that would result from the dramatic collapse of the vast ice sheets that cover Greenland, but that more work is needed to understand the wider effects. Greenland has more than two trillion tonnes of … Read more

To slash emissions, industries must capture carbon and store it

Carbon capture and storage is the only way for many industries to significantly reduce emissions, according to Sintef scientist Kristin Jordal.

The technology to help limit global warming to 1.5˚C already exists, but there needs to be the will to use it, according to Kristin Jordal, an engineer and senior research scientist at the Norwegian research organisation Sintef. As coordinator of the CEMCAP project, she and her colleagues have been investigating how to reduce greenhouse gas … Read more

What keeps Arctic scientists awake at night?

From the lack of methane sinks to the high suicide rates of indigenous populations, Arctic researchers are studying a range of issues.

By Annette Ekin In a year when Arctic warming rose to global prominence after temperatures hit a sweltering 32˚C inside the Arctic Circle, what are some of the specific issues that keep Arctic scientists awake at night? Horizon caught up with eight experts in Reykjavik, Iceland, at the 6th edition of the Arctic Circle assembly, … Read more

Eliminating coal, oil and natural gas is the easy part of fighting climate change – Johan Rockström

To stop climate change, it is not enough to eliminate the use of fossil fuels like brown coal, says Prof Rockström.

by Annette Ekin To avoid climate breakdown, eliminating fossil fuels is the easy part, according to Professor Johan Rockström, co-director of the Potsdam Institute for Climate Impact Research in Germany. He says that safeguarding biological resources such as water, soil and biodiversity will be the ultimate test of whether global warming targets can be reached. … Read more

Climate actions that lift people out of poverty are often most cost-effective

Limiting global warming to 1.5°C would save hundreds of millions of vulnerable people from being exposed to the extremes of a 2°C world.

The most cost-effective climate change actions are also those that could help us achieve sustainable development goals (SDGs) such as ending poverty and hunger, according to Dr Keywan Riahi, director of the energy program of the International Institute Applied Systems Analysis (IIASA) in Austria, who says the first step should be to cut our energy … Read more
