Climate change hitting harder and sooner

There is a serious conflict between people and nature, between people and the planet.

Top climate scientists issued a report 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 at the United Nations (UN).

The landmark new report, which was presented to the UN Climate Action Summit, underlines the glaring — and growing — gap between agreed targets to tackle global warming and the actual reality.

Compiled by the UN World Meteorological Organization (WMO), 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.

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.”

Swedish teen activist Greta Thundberg told hundreds of young people gathered at UN Headquarters for the first-ever Youth Climate Summit that “young people are unstoppable” and echoed her young compatriots who vowed to keep up the pressure on governments to make serious policy course corrections towards green energy and planet-friendly agriculture to seriously tackle climate change.

Guterres told the young activists that he feared “there is a serious conflict between people and nature, between people and the planet.” Saying that there is no time to lose, with so many people around the world already suffering from the impacts of climate change, the UN chief has been bluntly telling world leaders “don’t come to the Summit with beautiful speeches… come with concrete plans,” including carbon neutrality plans for 2050, options to tackle fossil fuel subsidies, taxing carbon and a possible end to new coal power sources after next year.

The findings presented by the report’s experts spotlight the sense of urgency. Amid growing recognition that climate impacts are hitting harder and sooner than climate assessments indicated even a decade ago, there is now a real risk of crossing critical tipping points, according to the scientists.

For example, the report shows that the average global temperature for 2015–2019 is on track to be the warmest of any equivalent period on record. It is currently estimated to be 1.1°Celsius (± 0.1°C) above pre-industrial (1850–1900) times.
