In the Environmental Health in Israel 2014 report, the major challenges related to climate change included developing a national action plan to cope with climate change . Other challenges included strengthening collaboration between the IMS and the MoH, and creating a nationwide database on the health implications of climate change. MoH, in collaboration with cutaneous experts and the Israel Society of Dermatology and Venereology, issued a position paper in February 2016 with the aim of raising awareness about the disease and its diagnosis, and of standardizing the treatment of diagnosed patients (

Heat waves increase According to an IMS report published in 2016, there has been a statistically significant increase during the last two decades in the frequency of heat waves , in which the average daily temperature was at least 6 o C higher than average for three consecutive days (Figure 2). A statistically significant decrease in the intervals between heat waves was also observed https://www.ehf.org.il/en/climate_change
High temperatures Average temperatures since 2000 are much higher than the average temperatures measured in the 1950s, 1960s, and 1970s (Figure 1). According to these measurements, June 2016 was the hottest month on record, with the average daily maximum temperature between 2.5 and 3.5 degrees Celsius higher than the average daily maximum temperature measured during the years 1995-2009

Why is a pr oble m? MDA issued a plea for parents to take particular care not to leave children behind in cars accidentally — circumstances that have led to a number of deaths in the past. A ctivities organized by the ministry of education will only be held in shaded areas, or under trees and close to a water source and air-conditioned facilities.

Prior to the Paris Climate Change Conference in 2015 Israel declared its goal of an unconditional economy- wide target of reducing per capita greenhouse gas emissions by 26%, from the levels measured in 2005. to be achieved by 2030: a 17% reduction in electricity consumption; the generation of 17% of consumed electricity from renewable energy sources; and a 20% reduction in transportation emissions. In 2016, the Israeli government approved a national plan to mitigate greenhouse gas emissions and to increase energy efficiency.
Mitigation Prior to the Paris Climate Change Conference in 2015, Israel declared its goal of an unconditional economy- wide target of reducing per capita greenhouse gas emissions by 26%, from the levels measured in 2005. This translates to specific policy targets in various sectors in the economy, to be achieved by 2030: a 17% reduction in electricity consumption; the generation of 17% of consumed electricity from renewable energy sources; and a 20% reduction in transportation emissions. In 2016, the Israeli government approved a national plan to mitigate greenhouse gas emissions and to increase energy efficiency.
The National Adaptation Plan for climate change Includes specific action plans for various government ministries, was initiated following a binding government resolution in 2009. The plan, which awaits government approval, identifies knowledge gaps regarding climate change in Israel and proposes a wide-ranging research plan to close these gaps. Following a government-wide consultation process, the plan reviews the impact of climate change and extreme weather events on various sectors in the economy, and suggests sectoral action plans, including the development and implementation of tools and technologies for coping with climate change Israel Ministry of Environmental Protection (updated November 2017).

Mitigation In 2015, the Ministry of Environmental Protection (MoEP) held a national conference on climate change. Representatives from 12 government ministries, academic institutions, nongovernmental organizations, the Israel Meteorological Service (IMS), and the Hydrological Service participated in the event, which focused on plans and strategies for climate change adaptation Israel Ministry of Environmental Protection (updated November 2017).

Mitigation The Ministry of Health’s (MoH) preparations for climate change have focused on short-term responses to extreme climatic events (e.g., heat waves, cold waves, and floods). This includes a plan to upgrade the preparation of hospitals and medical systems as part of the emergency system. The MoH published an infographic on climate change, which includes recommendations for coping with extreme heat waves, with an emphasis on the elderly . The MoH publishes warnings to the public on upcoming heat waves and extreme cold events, with recommendations for the general public and vulnerable populations, including the elderly and individuals with chronic disease. However, there is still a need for long-term preparations for climate change, including promoting research (with a focus on the implications for public health), improving the accessibility of relevant information to the public, and collection of clinical data, such as incidence and prevalence of climate- change related diseases.
