It is a must-read for governments, companies and scientists and the media should disseminate its contents: the Special Report on Global Warming of 1.5\u00b0C<\/a>, known as SR15, will establish the roadmap of our actions with the aim of reducing and adapting to climate change. SR15 is a step forward from AR5<\/a>, the report by the Intergovernmental Panel on Climate Change (IPCC<\/a>), which was published four years ago. The new report will be the basic scientific reference in the debates of experts from over 200 countries that will meet in Katowice (Poland) in December to celebrate the COP24<\/a>, the 2018 Conference of the Parties to the United Nations Framework Convention on Climate Change.<\/p>\n

The message of SR15 is clear and conclusive: limiting the increase of the average temperature of the atmosphere to 1.5\u00b0C is a key factor if we wish to avoid the worse consequences of global warming. The new report includes the forecasts of an increase between 1.5 and 2 \u00baC as well as its consequences, concepts that had not been taken into account by AR5.<\/p>\n

Exceeding this limit would imply a greater increase in heat waves, torrential rainfall and droughts, which would have a direct impact on the production of food, especially in sensitive areas such as the Middle East, the Sahel, India, Central America, South America and the Mediterranean countries and would influence migratory movements from areas of poverty, an increasingly worrying problem. The rise of the sea level is a phenomenon with incalculable consequences for all coastal communities.<\/p>\n<\/div><\/div>\n\n

Three years since the confirmation of change<\/h2><\/div>

Since the appeal of COP 21, the conference held in Paris in 2015, three tumultuous years have gone by that have confirmed the forecasts of AR5 and have even worsened them.<\/p>\n<\/div><\/div>\n\n

<\/div>

On the one hand, droughts, flooding and especially violent cyclones have hit large areas of the planet. Of particular significance have been the phenomena experienced in 2018, which have led to\u00a0unthinkable situations<\/a> in all continents. The heat waves and forest fires in areas close to the Arctic have contrasted with an unusual and sudden increase of violent phenomena in the Mediterranean region, an area with storms that have broken historic records claiming many victims.<\/p>\n<\/div><\/div>\n\n

In Paris, the 195 participating countries reached a global agreement by consensus to reduce the emissions of greenhouse gas as quickly as possible in order to keep global warming \u201cwell below\u201d 2 \u00baC. Since then, convulsive changes have taken place in the political sphere. The withdrawal of the US government from the agreement, with arguments generally based on the denial of climate change, which has been openly expressed by Donald Trump<\/strong>, meant a heavy blow to the UN expectations. However, it also opened the door to hope, as it caused an important change in China\u2019s position, which is considered the most polluting country in the world, as it produces 29% of the global emissions of greenhouse gas. Xi Jinping<\/strong>\u2019s government, which sees its country suffering the death of more than one million people due to pollution, is already implementing important measures following the Paris agreements.<\/p>\n<\/div><\/div>\n\n

Half a degree is decisive<\/h2><\/div>

SR15 states that at the rate at which we burn fossil fuels, we will exceed 1.5 \u00baC between 2030 and 2052. It also lowers the expectations generated in Paris, where 2 \u00baC was set as an insurmountable limit; many of the negative impacts already predicted if the atmosphere increased its temperature by 2 \u00b0C are more likely to happen now at only 1.5 \u00baC. The report also confirms that gas emissions have already increased the average temperature of the atmosphere by 1 \u00baC if compared with the period before the Industrial Revolution of the 19th<\/sup> century. This is one of the most worrying traits of the Anthropocene, the era in which nature is being altered by human activity.<\/span><\/p>\n<\/div><\/div>

The text of the IPCC also assures that in order not to exceed 1.5 \u00baC it is essential to accelerate the measures already implemented in most regions of the world and to expand their scope to all fields of the political and business world, but above all among the civil society which will need to change its lifestyle and energy consumption habits.<\/span><\/p>\n

Scientists are increasingly aware that every half degree is important for people and for nature and they warn that the effects for ecosystems and for life on the planet would be less catastrophic if that half degree could be lowered.<\/span><\/p>\n

At the presentation of SR15 in Incheon (South Korea) on the 1st<\/sup> October, the president of IPCC, Hoesung Lee<\/strong><\/span>, warned of the magnitude of the challenge we are facing: \u201dKeeping global warming at a level below 1.5 degrees instead of 2 will be very difficult, but not impossible.\u201d<\/em><\/span> Its vice-president, Thelma Krug,<\/strong><\/span> told <\/span>EFE Verde<\/a><\/span><\/span> that \u201cwe need to face unprecedented changes if we want to avoid exceeding this 1.5\u00baC, and it is essential to reduce CO2<\/sub> and other greenhouse gas emissions into the atmosphere to zero by 2050.\u201d<\/em><\/span><\/span><\/p>\n<\/div><\/div>\n\n

What do we need?<\/h2><\/div>

Krug herself admitted there is still not enough technology to achieve it if we intend to keep the global temperature at 1.5 \u00baC, but this technology will become available if economic incentives are developed. A key part of this enormous transformation will be the restructuring of the financial system in order to accelerate the investments in technology, solutions and associations that are necessary to decarbonize the economy and, above all, to promote a change of behavior, a key factor for the new model to be successful.<\/span><\/p>\n<\/div><\/div>\n\n

<\/div>

In this sense Europe is at the forefront of the development of policies and frameworks to support a fast and significant transition towards a circular economy without carbon emissions, with initiatives such as the <\/span>Action Plan on Sustainable Finance<\/a><\/span><\/span> driven by the <\/span>European Commission<\/a><\/span><\/span> of the EU. The IPCC estimates that an investment of around 2.4 trillion dollars (approximately 2.5% of the global annual GDP) is needed in the energy system between 2016 and 2035.\u00a0\u00a0<\/span><\/p>\n<\/div><\/div>\n\n

Collaboration in communication<\/h2><\/div>

Apart from the development of technological tools and regardless of the advances towards a circular economy, the dissemination of the message of the SR15 is essential to achieve a deep social change that leads to global awareness. United Nations will double its efforts in communication, as already advanced by Alison Smale<\/strong><\/span>, United Nations Under-Secretary-General for Global Communications, when she visited the We Are Water Foundation last February and she stressed the importance of collaborating in the dissemination of objective and intelligible messages. \u201cThe We Are Water Foundation has the gift of clearly addressing complex issues. \u2013 <\/em><\/span>Smale pointed out \u2013 And it does this by means of powerful initiatives and communication tools that we need to keep and protect. Especially in the 21st<\/sup> century, in a world filled with digital information noise, we need to generate messages that get to the essence of things. This is the goal of the We Are Water Foundation and it coincides with that of United Nations, therefore we need to work together to work better.\u201d<\/em><\/span><\/span><\/p>\n<\/div><\/div>\n\n

<\/div>

As a result of this visit, Alison Smale <\/strong>invited the We Are Water Foundation to the UN Headquarters in New York City to hold several meetings with communication officers of UN Water of theDepartment of Economic and Social Affairs (UN DESA)<\/a> and the UN regional Information Center (UNRIC<\/a>). Xavier Torras<\/strong>, director of the We Are Water Foundation, commented: \u201cThese have been very fruitful meetings in which we have addressed some of the key aspects of our communication work and how we intend to work together. The fight to achieve water security and all SDGs involves raising awareness of climate change and its consequences. It is a challenge that requires maximum collaboration and I am convinced we are on the right path to achieve it.\u201d <\/em><\/p>\n<\/div><\/div>
