Big data has many novel applications across industries and historical periods. Scientists can use information gathered 100 to 150 years ago to accurately assess the world’s climate change and predict possible outcomes based on current actions. New data-gathering technologies and projects aim to detect spikes in harmful emissions and subtle localized changes. They can help governments locate patterns in climate changes across regions and allow for more actionable insights compared to raw information. Real-time information combined with a government devoted to action against rising global temperatures can be the most effective tool in fighting climate change. Big data can rapidly gather and analyze information on food availability, emissions, transport requirements, and the energy industry, all of which have a massive impact on emissions. The results can be applied locally with overreaching effects across the globe.
