City Talks is a hub for everything environmental and climate science. Every City Talks’ ideas festival gathers people that have the passion about making our environment livable for the coming generations.

Conservationists, oceanographers, ecologists and environmentalists, entrepreneurs, scientists, artists, community leaders, entertainers, decision-makers, tech and social innovators always meet at City Talks Ideas festivals to challenge one another on humans’ lifestyle and its impact on the climate and predictions on the current environmental trends.

When one talks about trends related to environmental challenges we’re facing, what comes to mind are the effects of the constantly increasing levels of global warming. 

Taking a sneak peek into the near future, whether global warming will get worse or not, is something that can only be based on certain observable and unseen phenomena, trends and human lifestyle. 

Either way, however, Mother Earth will feel the impact at least by 2100.

Despite efforts, by humans, to limit climate change effects, it’ll be too late to save many lowland areas of the world. Sea levels will rise almost two metres by the late 2090s, displacing hundreds of millions of people. Many cities and nations across the globe like, for instance, the Maldives will be hard hit, with most of the nation disappearing underwater. Countries around the world will be forced to begin large-scale evacuation and resettlement programmes, while trillions of Euros will be spent on coastal defences.

It’s also predicted that by the year 2099, over 80% of the Amazon rainforest will have been lost due to the combined impacts of logging, drought, forest fires, desertification, agriculture and industrial expansion. This means that less than one-fifth of the Amazon now remains.

In addition to mass extinctions of flora and fauna, many indigenous peoples' communities will have vanished.

As a result of the predicted population growth, masses of people will undoubtedly undergo unprecedented strain and, at least 40% of people, will live in areas with low water resources. 

Without major strides in combating global warming, we’re yet to see wars and conflicts, over increasingly limited food and freshwater resources resulting from enormous shortfalls in crop production and uncontrollable rise in sea levels respectively.

Even if global warming is predicted to get worse, if no substantial measures are put in place by policymakers, many innovators and information technology experts still think otherwise. 

For instance, it’s been predicted that Google Earth and similar services could potentially turn everyday dwellers into responsible ocean conservationists. 

This will, however, depend on their access to energy. 

Humans will need clean energy technologies and different other types of energy innovations to be able to access true energy independence.

The predictions are all over the map.

It’s predicted that by 2020, all new cars in the United States will be hybrids, 20 per cent of the European Union's energy will be coming from renewables, 15 per cent of China's energy will be coming from renewables and a country like Sweden will be oil-free.

It’s also said that by 2022, 36 billion gallons of biofuels will be sold in the United States, compared to around 4.7 billion gallons in 2007.

By the year 2025, almost 25 per cent of United States’ electricity will be coming from renewables (according to a 2008 Obama’s Clean Power Plan that was reviewed by the Trump administration on March 28, 2017).

Even as you’re reading this article, many innovative companies are using different types of energy technologies like Hydrogen.

The use of Hydrogen to this day is mainly dominated by industry, namely: oil refining, ammonia production, methanol production and steel production.

Virtually all of this hydrogen is supplied using fossil fuels, so experts strongly believe there is significant potential for this molecule to have a fundamental role to play in facing the climate challenge.

City Talks ideas festivals’ attendees usually hear talks and discuss major environmental predictions and strategies for mitigating the possible effects on a global, as well as, local perspective.
