People's need to travel faster, safer, and more efficiently has fueled the invention of great technological solutions. During the last decades, the impact of technology on travel has become even more significant thanks to the application of new IT services, (34)______ to the rise of the online travel market and the increasing digitalization of the travel industry. An important achievement behind the online travel experience dates back to the 1960s (35)______ the first global distribution system (GDS) was introduced. GDSS are online networks connecting suppliers- (36)______ airlines, hotels, or cruise lines - to providers, like travel agencies and online travel agencies. Having access to the suppliers' inventory, like the number of seats or hotel rooms available, GDSS allow providers to (37)______ such information, helping customers book multiple travel services at once. In 2021, the market size of the global distribution system industry worldwide was estimated at approximately six billion U.S. dollars. That year, the air distribution business segment of Amadeus, one of the (38)_______ renowned GDSS worldwide, generated roughly one billion U.S. dollars in revenue.

Temperatures in the Middle East have exceeded 50°C this summer. In the United Arab Emirates (UAE), a heat wave brought the highest temperatures on record for that period of the year. Meanwhile, rainfall is limited to a few millimeters per year. However, several videos have appeared on social networks showing downpours in the area. This is why many have suggested that the United Arab Emirates created artificial rainfall.
Cloud seeding is a weather manipulation practice that has been around for 80 years. It is a form of geoengineering that is often the subject of controversy because its effectiveness remains questionable. It is released by substances such as silver iodide in the cloud, which catalyzes the condensation of water droplets and produces artificial rain.
Silver iodide acts as a "scaffold" to which water molecules can attach until they become so heavy that they fall to the Earth's surface. In this way, simple clouds could theoretically transform into true storms, capable of resisting drought.
In the United States, artificial rain generation was also used in the military before it was banned by the United Nations. However, its effectiveness in conflict has never been proven. Weather manipulation is used to prevent violent storms from breaking through the clouds. Starting in 1990, the UAE launched a government-funded research center dedicated to cloud seeding.

In the European Union we are embracing the clean energy transition. An effective way of doing so is through the development of advanced and competitive green technology-we want Europe to be the world leader in this field. To work towards this goal we have set ourselves short and mid-term targets of a 20% share of renewables in our energy system by 2020, and 27% by 2030. Achieving these targets won't be easy, but we have set up the instruments and tools necessary to facilitate the shift. We have legislation establishing the overall policy for the promotionof energy from renewable sources, including specific national targets to facilitate implementation.
Our efforts are bearing fruit: recent data from the European Environment Agency for 2014. demonstrate that, thanks to renewables, fossil fuel use has been reduced by an estimated 114 Mtoe (megaton oil-equivalent), comparable to the fossil fuel consumption of France. In absolute terms, Germany, Italy and Spain achieved the largest reduction in domestic fossil fuel use and avoided greenhouse gases emissions, as a result of national renewable energy deployment since 2005. All in all, around 380Mt of carbon dioxide emissions have been avoided, which is equivalent to the yearly emissions of Poland.
These results come together with opportunities for investment and growth. Investments historically allocated to fossil fuels are gradually shifting towards renewables and other sources of clean energy. By 2030, according to the International Energy Agency, we expect investment in renewables to be almost three times the investment in fossil fuel power plants. This is a tremendous opportunity to position European energy companies at the head of the new global market of low carbon technologies and one which they are beginning to seize. According to the 2015 State of Renewable Energies in Europe report, the renewable energy sector generated a turnover of €143.6 billion and over one million jobs in Europe in 2014. Wind energy has been the main driver of growth and jobs, accounting for 324,000 jobs and a turnover of €48.3 billion in the same year.
