Physical science of climate change
We know beyond reasonable doubt that the Earth’s climate is warming. The rate of warming from the 1950s up to today is unprecedented compared to previous decades and millennia. These are the conclusions of the Intergovernmental Panel on Climate Change (IPCC)’s Fifth Assessment Report, a collective study by hundreds of eminent scientists to assess the latest evidence on climate trends and efforts to mitigate and adapt to climate change. More than 180 governments have endorsed their conclusions.
What is causing this warming? The IPCC finds it is extremely likely that humankind’s production of greenhouse gases is to blame: there is 95% scientific certainty.
The IPCC warns that continued increases in global emissions at this rate could lead to rises in the average global temperature of between 2.6 – 4.8 degrees Centigrade by the end of the 21st century. Global warming of this scale would change our natural environment profoundly, with more negative than positive effects on societies, economies and cultures. Even if the global community reduces greenhouse gas emissions now, the climate will continue to change as there is some momentum in the system based on past emissions. The world faces an era of ‘committed climate change’ for the next few decades, during which people will live with rising risks.
CDKN has been heavily involved in ‘digesting’ the IPCC’s science and making the key facts accessible and usable by diverse audiences. Explore here some of our communications toolkits to help you understand and share the key messages of the IPCC’s work.
A webinar from the Future Climate for Africa programme on 29 November will share practical recommendations and approaches to communicating climate change information, including uncertainties. It will draw on insights from cognitive psychology and experiences from FCFA's work in west and southern Africa. [more...]
Suzanne Carter looks at how the producers and users of climate information can build trust and ultimately work to make weather and climate services more useful in planning for development. [more...]
The 'Triangle City Cooperation' project - part of the Climate Resilient Cities in Latin America initiative - has not only furnished evidence and solutions to combat climate vulnerability in the tri-border area of Argentina, Brazil and Paraguay. It has also catalysed new forms of tri-border cooperation among the countries, to build their collective climate resilience. [more...]

On Thursday 19 May 2016, India experienced an all-time record high temperature for any calendar day. The high temperature reached 51°C in the city of Phalodi in the Jodhpur district of the state of Rajasthan. The Raising Risk Awareness project studied whether human-induced climate change had any role to play in the extreme weather.
This paper shows how sea level rise under a 1.5, 2 or 3C increase in global temperature will affect Bangladesh, based on analysis of changes in glood depth, area, and population affected under the Delta Dynamic Integrated Emulator Model.
