Al Gore, former vice president and current chairman and founder of the Climate Reality Project, recently discussed about the climate crisis at this year's South by Southwest (SXSW) Festival in Austin, Texas.

In the discussion, he has focused on a need to punish politicians who deny the current problems in climate change.

SXSW, which is running from March 9 to 22 this year, is a large film and music festival running annually for around past 20 years. During SXSW, designers, developers, investors, entrepreneurs, and politicians come together for many days of discussions about technology, innovation, and the future.

Gore, coming back for the third time in the previous few years, has on Friday called on the tech-minded SXSW crowd to utilize technology in tackling climate change and to put the focus on those who deny it.

According to the Chicago Tribune, Gore said, "We have this denial industry cranked up constantly. In addition to 99% of the scientists and all the professional scientific organizations, now Mother Nature is weighing in".

In addition to it, Gore said that forward-thinking investors have started moving away from the companies that invest in fossil fuels towards the companies investing in renewable energy.

Gore referred to a proposed federal cap-and-trade system that would be penalizing the companies that exceeded their carbon-emission limits, and said that they need to put a price on carbon, if they want to accelerate these market trends. He states that to do it, they need to put a price on denial in politics.

As per MacWorld, Gore has given an inspired talk about getting the climate change movement going at the Festival, and has stated that the next generation will look back at them to ask how did they change?

Gore said that a group of people came to South by Southwest in Austin, Texas, in 2015, to help bring a revolution and it may become the part of the answer.
