2014 the hottest year on record

The average global temperature is going up and 2014 was recently concluded to be the hottest year since records began.

RCP 8.5 now charted

Countdown towards COP21 in Paris in December 2015 has started

COP21 in Paris will debate and decide on a new Global Climate Change Policy to follow-up on the Kyoto Protocol from 1997. Therefore, 2015 is a crucial year for new analysis and research on the different aspects of health and well-being impacts of climate change. All readers of this website are encouraged to contribute new results via any national or international journals, in order to make the decisions in Paris based on scientific evidence reflecting all aspects of the health impacts. We will expand our own communication activities via this website.

The average global temperature is going up and 2014 was recently concluded to be the hottest year since records began. Article

Assessment for WHO of Occupational Heat Stress now on ClimateCHIP

The Hothaps team prepared some time ago a health impact assessment of Occupational Heat Stress for the WHO project on "Quantitative Risk Assessment of the health effects of Climate Change". The Final WHO report on this project was limited to Mortality estimates, and the Occupational Heat Stress section was not included there. However, it has now been published as Technical Report 2014:4 on the ClimateCHIP website. 

COP20 in Lima highlights importance of health

During the climate change policy meeting in Lima in December the importance of analyzing and acting on public health threats from climate change was stressed. Article

Tony McMichael dies: a tragic loss for the global climate change and health community

Professor Emeritus Tony McMichael passed away on 26 September 2014 after a short period of serious illness and a week before his 72nd birthday. He was an eminent epidemiologist with a long career in public health research, teaching and advocacy. His work included studies of nutritional, occupational and environmental health issues, and during the last 20 years at the London School of Hygiene and Tropical Medicine and the Australian National University he focused on the major global health risks of the emerging climate change. The first detailed analysis of climate change impacts on public health was published in 1996 by WHO with Tony as the main author. After that he published numerous research papers on the topic and headed further global analysis reports, which provide much of the evidence for our current understanding of climate change impacts on health. Tony inspired me and helped develop the Hothaps program. He sat next to me at an IPCC meeting in New Delhi in 1999 when we realized that the occupational health hazards of climate change were until then totally overlooked in the global discourse. Tony was a good friend and colleague during many years and will be sorely missed.

Hothaps paper published during UN climate summit

On the 23rd September, the United Nations held a major climate change policy meeting in New York,wherea large number of presidents of countries made speeches promoting global and local actions to curb climate change. A key background document was a Commission report on “The New Climate Economy”. This report estimated that the economic benefits of climate change mitigation justify major investments in alternative energy production. However, reduced labor productivity impacts that the Hothaps program focuses on, were not addressed. Increased workplace heat exposures are not just a health problem, but may also lead to trillions of dollars of foregone economic outputs around the world. A comment based on recent research was published in the United Nations University “Our World” journal: website

Report on climate change economic impact on the USA

A report from the Risky Business organization published in June has quantified the potential economic impacts of climate change on the USA. Labor productivity loss (a key ClimateCHIP issue) has been given its own section. Full Report

Press Release: Nelson Marlborough Institute of Technology

Heat Stress Research Aimed at Helping Workers. A team of Nelson-based researchers hopes their work will one day lead to improvements in the lives of workers in some of the world’s hottest places. The Hothaps research team is led by Professor Tord Kjellstrom and includes Nelson Marlborough Institute of Technology (NMIT) tutors Bruno Lemke and Matthias Otto as well as Drs Olivia Hyatt, Chris Freyberg and Dave Briggs. Full Press Release.

Collection of scientific papers on Workplace Heat and Occupational Health

The Journal Industrial Health (from the Japan National Institute of Occupational Health) published in February 2013 a series of papers on this topic with climate change impacts as a common theme. The papers highlight the need to assess and act on workplace heat as a health challenge as the climate gets hotter in already hot places around the world.  Free Papers.

Global and national analysis of impacts and costs of climate change
A major report on this topic was published late in 2012:  the Climate Vulnerability Monitor, 2012. It contains the first ever comprehensive analysis by country of both health and other impacts and the likely related costs in US$ PPP. It concludes that the costliest effect of climate change already in 2030 may be the loss of labor productivity due to increasing heat in workplaces.  Full Report.

Global Public Health data on the web via Gapminder
The global and local climate data presented via Climate CHIP aims at making large datasets available for use and interpretation by both scientists and lay people at local level around the world. A similar approach was developed several years ago by Professor Hans Rosling and colleagues in Sweden. The website Gapminder gives access to very creative analysis tools for national health and determinants data.

The Climate and Health Alliance was established in August 2010. It is an alliance of health care stakeholders which includes health care professionals from a range of disciplines, health care service providers, institutions, academics, researchers, and health care consumers across Australia who wish to see the risk to human health from climate change addressed through prompt policy action.
