Leading scientists warn climate change ‘hitting harder and sooner’ than forecast

New York, 22 September 2019 – The world’s leading climate science organizations have joined forces to produce a landmark new report for the United Nations Climate Action Summit, underlining the glaring – and growing – gap between agreed targets to tackle global warming and the actual reality.

The report, United in Science, includes details on the state of the climate and presents trends in the emissions and atmospheric concentrations of the main greenhouse gases. It highlights the urgency of fundamental socio-economic transformation in key sectors such as land use and energy in order to avert dangerous global temperature increase with potentially irreversible impacts. It also examines tools to support both mitigation and adaptation.

“The Report provides a unified assessment of the state of our Earth system under the increasing influence of anthropogenic climate change, of humanity’s response thus far and of the far-reaching changes that science projects for our global climate in the future. The scientific data and findings presented in the report represent the very latest authoritative information on these topics,” said the Science Advisory Group to the UN Secretary-General’s Climate Action Summit.

“It highlights the urgent need for the development of concrete actions that halt the worst effects of climate change.”

The largest glacier in the Swiss Alps, the Aletschgletscher, is melting rapidly and could disappear altogether by 2100.

Top climate scientists issued a report on Sunday showing that over the last several years, sea-level rise, planetary warming, shrinking ice sheets and carbon pollution have accelerated; a sobering call to action for political leaders headed to New York for summit-level climate change talks tomorrow at the United Nations.

Among other findings, the report says that accelerating climate impacts from melting ice caps to sea-level rise and extreme weather were to blame for the record as the global average temperature increased by 1.1°C above pre-industrial (1850-1900) times and 0.2°C warmer than 2011-2015.

It highlights the urgency of fundamental socio-economic transformations and carbon-curbing actions in key sectors such as land use and energy to avert dangerous global temperature increase, with potentially irreversible impacts. It also examines tools to support both mitigation and adaptation.

The assessment from the world’s top climate experts and scientific organizations comes not just ahead of the UN summit, but also against the backdrop of last week’s global ‘climate strike,’ which saw millions of students across the world take to the streets to demand real action from politicians and big corporations to reverse the impacts of what UN Secretary-General António Guterres has called a “climate emergency.”
