Record rains ravage Chennai

India’s increase in extreme precipitation events in recent decades is likely tied to climate change. Following Southern India’s wettest November in more than 20 years, December 2015 began with a new round of extreme precipitation that inundated the city of Chennai. While November and December are typically very wet, the rainfall and flooding of 2015 were exceptional.

Tracking Climate Change

In a stable climate, the ratio of new record highs to new record lows is approximately even. However in our warming climate, record highs have begun to outpace record lows, with the imbalance growing for the past three decades. This trend is one of the clearest signals of climate change that we experience directly.

Loss

Loss and Damage

There are limits to adaptation. Some climate impacts are already exceeding the the abilities of affected populations to adapt, causing loss and damage. The question of how to address these losses and damages is a key issue in the international negotiation process.

Alaska: Climate Change Ground Zero

The Earth’s temperature is now increasing faster than anytime in the last 1,000 years. Alaska and the Arctic, temperatures are rising at twice the global rate—more rapidly than anywhere else in the world, making the region ground zero for climate change. The best estimate is that human activity is responsible for all of the observed increase in global temperatures since 1985. The effects of the temperature changes are transforming a once-frozen seascape into an evolving, navigable ocean. These rapid changes occurring in the North have created a new Arctic climate system.

Climate Change Fuels Record Hot Summer’s Latest Heat Waves

The Japanese Meteorological Agency has announced that this past July was the warmest on record, a finding reinforced by preliminary NASA data. This means July was likely the hottest of any month on record, and puts 2015 safely on track to beat 2014 as the hottest year on record.

Goals

Long-Term Goals

One big question for negotiations at COP21 is whether to develop a long–term global goal for climate action, and if so, what that goal might look like. While all the long-term goals aim to avoid catastrophic climate change, each one proposes a different way to get there. Navigate the maze here.

Climate Change

The Candidate’s Guide to Climate Change

Climate change is no longer a niche political issue. Recent events such as the drought in California and Superstorm Sandy have brought extreme weather to the forefront, and people are searching for information on climate and weather connections. Voters, reporters and debate moderators are increasingly asking questions about climate change.

National Security

National Security Risks

Existing analysis from respected military leaders recognizes the potential threat from climate change as no less than massively destructive and an enormous risk to national security.

Fossil Fuel Companies

The world’s largest oil and gas companies have sky-high budgets, top scientists in their employ, and an incentive to plan for the long term due to their massive investments in permanent infrastructure. They are neither altruistic nor clueless, and they are taking climate change seriously. This includes planning ahead for a future with strong climate policies
