President Obama joined leaders and diplomats from more than 190 countries who convened in Paris today to kick off a two week effort towards negotiating an international climate change agreement. The United Nations' sponsored event, the largest gathering of world leaders in history, is an urgent, sweeping attempt to reduce global carbon emissions and stave off the worst consequences of climate change.
2015 is on track to be the warmest year on record. In fact, nearly all of the warmest years on record have occurred since 2000. During that time, the frequency of extreme weather events -- from droughts and floods, to hurricanes and freezes -- have also risen significantly. The vast majority of scientists agree that these changes largely stem from a rapid increase in greenhouse gas emissions, primarily from the burning of fossil fuels.
Perhaps the greatest inequity of the crisis is that those least responsible for contributing to climate change -- people of the world's poorest nations -- will likely continue to be the most adversely impacted by its consequences.

A good short explainer on the basic science of climate change, narrated by celebrity scientist Bill Nye ("the Science Guy") and produced by the Climate Reality project.
Climate map: the global culprits and victims
The Carbon Map was created by Duncan Clark and Robin Houston from the design firm KILN as an entry in the World Bank’s Apps for Climate competition. Recently updated and featured on The Guardian's site, the map resizes the world's geography so as to reflect the nations that are most responsible for climate change and those most vulnerable to its impacts. Click the PLAY button to see a demo. Listed below the map is a collection of additional interactive climate change resources.
NASA's Climate Time Machine
A series of visualizations showing how some of the world's key climate indicators like global temperature, sea ice and carbon levels have changed over time.
Produced by the Global Carbon Project, this visualization shows the past, present and future of carbon production and its environmental impacts.
Climate Hot Map
Produced by the Union of Concerned Scientists, this map tracks climate change-related impacts in locations around the world. Indicators include heat waves, sea-level rise, flooding, melting glaciers, earlier spring arrival, coral reef bleaching, and the spread of disease.
How hot has it gotten in your lifetime (and how much hotter will it get)?
Also created by Duncan Clark from Kiln (and featured on the Guardian), this interactive shows predicted temperature changes in your lifetime.
Climate change crisis guide
An extensive interactive guide on climate change, produced by the Council on Foreign Relations.
