Here's a running list of all the ways climate change has altered Earth in 2019


Earth is now the warmest it's been in some 120,000 years. Eighteen of the last 19 years have been the warmest on record. And concentrations of carbon dioxide -- a potent greenhouse gas -- are likely the highest they've been in 15 million years. The consequences of such a globally-disrupted climate are many, and it's understandably difficult to keep track. To help, here's a list of climate-relevant news that has transpired in 2019, from historically unprecedented disappearances of ice, to flood-ravaged cities.

Extracting Urban Microclimates from Electricity Bills

AAAI Conferences

Sustainable energy policies are of growing importance in all urban centers.Climate — and climate change — will play increasingly important roles in these policies.Climate zones defined by the California Energy Commissionhave long been influential in energy management.For example, recently a two-zone division of Los Angeles(defined by historical temperature averages) was introduced for electricity rate restructuring.The importance of climate zones has been enormous,and climate change could make them still more important. AI can provide improvements on the ways climate zones are derived and managed.This paper reports on analysis of aggregate household electricity consumption (EC) data from local utilities in Los Angeles,seeking possible improvements in energy management. In this analysis we noticed that EC data permits identificationof interesting geographical zones  — regions having EC patterns that are characteristically different from surrounding regions.We believe these zones could be useful in a variety of urban models.

An Overview of Recent Application Trends at the AAMAS Conference: Security, Sustainability and Safety

AI Magazine

A key feature of the AAMAS conference is its emphasis on ties to real-world applications. The focus of this article is to provide a broad overview of application-focused papers published at the AAMAS 2010 and 2011 conferences. More specifically, recent applications at AAMAS could be broadly categorized as belonging to research areas of security, sustainability and safety. We outline the domains of applications, key research thrusts underlying each such application area, and emerging trends.
