THIS Sunday, GMA News and Public Affairs present "Signos: Banta ng Nagbabagong Klima."

"Signos" tackles the impact of climate change in the country, and confronts the environmental signs that point to a potentially disastrous future.

In the Philippines, it is believed that natural disasters of alarming proportions are some of the signs of climate change. In Bauang, La Union, the rising sea has eaten more than half of the town. Farmers in different areas of the country are also experiencing a significant drop in crop yield.

Meanwhile, super typhoons Reming and Milenyo that hit the Bicol region two years back triggered a landslide that covered villages in Albay with lahar and other volcanic materials. Flashfloods wiped out a town in Davao del Sur. In El Nido, Pala-wan, corals are severely damaged due to rise in sea-water temperature, while in Quezon, there is a surge in malaria cases.

Climate change is a result of centuries of industrialization and the improper exploitation of the Earth’s natural resources. If human activities continue to go unchecked, the impact of climate change can be expected to take a turn for the worst.

With refreshing visuals and high-end graphics, "Signos" is a must-see television event that is sure to hook viewers, while imparting significant information. It tells the story of how humans have altered the face of the environment, threatened human health and biodiversity, but shows at the same time that it is not too late to change mankind’s destiny.

Behind "Signos" is a team of seasoned reporters from GMA News and Public Affairs. Executive Producer Marilen Go-Nuñez believes global warming is one issue that calls for attention. "We made our best effort to make people understand why the talk on climate change is important. If we are able to get people involved in this dialogue, that is already an achievement for us," Go-Nuñez says.

Senior reporters Howie Severino, Maki Pulido, and Raffy Tima also provide insight into the issue of climate change. They traveled to different local regions to document how climate change affects Filipinos. With a panel of science experts, they engage in a round table discussion on global warming, its consequences, and the steps that must be taken to avert its catastrophic impact.

"Signos" is narrated by actor and environmentalist Richard Gutierrez.
