With #COP26 underway, we are at a critical moment in meeting the #ParisAgreement. Let’s seize the opportunity to shift towards low-carbon, healthier, and more resilient societies.

Future Earth, the World Climate Research Programme, and the Earth League have published the 10 Insights in Climate Science 2021 report to help policy makers and the public better understand what is needed: https://10insightsclimate.science

#10ClimateInsights

More than 50 leading global researchers have collaborated to produce the 10 New Insights in Climate Science 2021, a horizon scan of research that addresses our ongoing #climatecrisis.

This year’s report covers megafires, growing methane emissions, and the need for just climate action, among other critical science findings – as well as their implications for local, regional, and global policy.

Staying within 1.5°C will require transformations across all sectors, including deep decarbonization, and drastic coordinated global action to support lower-income countries in making climate-smart transitions as well as holding the highest emitters to account.

 Join Future Earth, the World Climate Research Programme and the Earth League in calling for more ambitious cuts to curb our #climatecrisis.

 New estimates show that rapid reductions of 2 gigatonnes of CO2 per year are required to keep warming to within 1.5°C, with net zero emissions reached by 2040.

Emissions of both methane and nitrous oxide from the agricultural sector are the main cause of their large growth, with waste treatment in landfills and fugitive emissions from fossil fuel extraction major sources of methane.

Nitrous oxide and methane emissions are derailing efforts to stay within 1.5°C of global warming. Agriculture, waste treatment, and landfills are major culprits.

Large greenhouse gas emissions released by megafires enhance positive fire-climate feedback, which sustain and worsen conditions that increase the likelihood of even more devastating wildfires.

Worsening fire regimes (more frequent fires, more intense fires) also come with increased risks to respiratory and cardiovascular health, birth outcomes and mental health for rural and urban communities.

We are entering a new age of intensifying extreme fire regimes (megafires), worsened by anthropogenic climate change according to @FutureEarth @WCRP_climate and @TheEarthLeague.

Some tipping elements, for example melting ice sheets and changes to ocean currents, but also deforestation of rainforests, influence each other, with recent research indicating that interactions among tipping elements can ultimately cause shifts to happen at lower levels of global warming than anticipated.

A just distribution of the carbon budget would require the richest 1% of the global population to reduce their current emissions by at least a factor of 30, while per capita emissions of the poorest 50% of the global population could increase by around three times their current levels on average.

Just sustainability transitions could require the richest 1% to cut their emissions by a factor of 30 or more.

In order to stay within the 1.5°C target it is necessary to at least halve mean global household CO2 emissions by 2030, with very steep reductions required for wealthy households (e.g. the wealthiest 10% in the EU will have to cut their footprint by almost 90%).

Limited global coverage and generally low price levels mean that carbon prices have only had a small impact on emission trajectories.

10 New Insights in Climate Science

A year of climate-related science in review

Each year we consult researchers and carry out a horizon scan in fields related to climate change on what the latest findings and most important new emerging fields are. We summarize this in 10 important scientific insights, and the result has always been a rich and valuable scientific synthesis for policy and society at large, a testament to the ever-expanding and improving knowledge of our planetary climate systems and the interactions with the human world.
