EU Coal Phase Out

When should the EU shut down its 300+ coal plants to meet the Paris Agreement's long-term temperature limit? Our new report outlines a science-based schedule for a coal phase-out in Europe.

Ratification Tracker

The Paris Agreement has entered into force in November 2016, when the double threshold of 55 countries and 55% global emissions was crossed. We continue to track the progress of ratification on this page.

The ‘Islands COP’ 2017: 1.5°C Science, Significance and ingredients for success

Fiji’s presidency of COP23, the first ‘Islands COP,’ offers an opportunity for SIDS and other most vulnerable countries to put their concerns and ambitions at the forefront of the negotiations and in the implementation process. This event will present the latest science on climate impacts on small islands to underscore the urgency of action, discuss the key ingredients for success of COP23 and opportunities to accelerate Paris Agreement implementation.

Half a degree could make a world of difference

Observational records show us that half a degree of warming in the recent past has brought significant increases in extreme weather events, which provides another line of evidence for what an additional 0.5°C of warming could entail.

Why Half a Degree Really Matters

Why Half a Degree Really MattersEcoWatch

Researchers now know the difference half a degree can make. They can tell you why 1.5°C warming would be better than a 2°C climb in average global temperatures, because even half a degree Celsius could mean greater extremes of heat, more overwhelming rainfall and longer spells of warm weather.

Half-a-degree of warming boosted extreme weather

Half a degree Celsius of global warming has been enough to increase heat waves and heavy rains in many regions of the planet, researchers reported Friday. Comparing two 20-year periods—1960-79 and 1991-2010—between which average global temperatures jumped 0.5 C (0.9 F), scientists found that several kinds of extreme weather gained in duration and intensity.

Publications

This special feature of the journal Regional Environmental Change examines biophysical impacts under different warming scenarios (1, 1.5, 2, and 4 °C warming) and considers scientifically derived development impacts to gain a better understanding of vulnerability to climate change. The main contributions to this special feature are five regional impact papers summarising climate impacts in Sub-Saharan Africa, South Asia, Central Asia, Latin America and the Caribbean and Middle East and Northern Africa.  
This commentary in journal Nature Climate Change discusses how evidence from the observational climate record provides useful guidance in discriminating the climate impacts of half-degree warming increments, which is high on the science agenda since the adoption of the 1.5°C temperature limit in Paris Agreement.
