Coastal flooding has increased dramatically along the East Coast in recent decades, a new study has found, and it's posing major challenges for local governments in many of the nation's most densely populated cities.

Rising greenhouse gas emissions are changing Earth's climate faster than at any time in human history, so the yardsticks we use to gauge what a 'normal' climate is will have to change too, the World Meteorological Organization said this week.

Monday It Will be 80 degrees in Yellowknife
By: Dr. Ricky Rood

As the polar vortex mutated through the media, it was recognized early as naïve, mocked by comedians, dismissed as scientifically imprecise and politicized. It then becomes a trigger, that supports the doubt that is the goal of the political argument to disrupt climate-change and energy policy. This is a case when the pursuit of simple metaphors and snappy descriptions of complex events fuels the rhetoric. It is a fundamentally flawed tactic of communication and a fundamentally robust way to capture attention and fuel disruption. We must do better.
Sea-Level Variability: A Primer
By: Dr. Ricky Rood
Published: Júl 9, 2014
Final question: How does climate change affect sea level? The usual suspects are listed as changing the temperature of the ocean and adding water to the oceans from melting ice. These are important and act globally. Climate change and climate variability are also realized in changes to ocean currents. Since these currents are often close to the coasts, there are potential large, rapid and localized changes to sea level. The changes in surface currents in the ocean are related to changes in the stress of winds on the surfaces; hence, there are changes related to atmosphere pressure patterns. There is local variability due to storms and storm surges. And as the ice melts, the land might rise, might fall, also an effect due to climate change. These sources of variability will be important to planning in the next decades, but on the time of a century or longer, adding water to the ocean from melting ice will dominate; there’s really nothing working against it.
North Carolina's Friendly Mountain Breezes, Sandy Beaches and Sea-Level Rise
By: Dr. Ricky Rood

The areas I have talked about here, the North Carolina and Virginia coasts, are areas where I have spent time. Much of my childhood was building and rebuilding home-contrived ways to protect our cabin on the Neuse River in North Carolina. One lesson you learn in this little world is that if you don’t have a plan up and down the shore, what you do is vulnerable to what your neighbors don’t do. They are vulnerable to what you do. One can’t adapt to 39 inches of sea-level rise alone. The scope of planning required, neighbors, cities, counties and states is daunting. Decisions will not be uniform. And to add to the challenge, if we plan for 30, 50 or 100 years, all of those plans have to anticipate that sea level will still be rising. Thinking of that meter of salty water in places I have lived and worked makes it crystal clear that we need to work for the best future rather than preservation of the past.
Wunderground's Climate Change Position
Based on the evidence, more than 97% of climate scientists have concluded that human-caused climate change is happening. Climate change is already causing significant impacts to people and ecosystems, and these impacts will grow much more severe in the coming years. We can choose to take economically sensible steps to lessen the damage of climate change, and the cost of inaction is much higher than the cost of action.

May 2014: Earth's 2nd Consecutive Warmest Month on Record

May 2014 was Earth's warmest May since records began in 1880. The planet has now had two back-to-back warmest months on record, since NOAA also rated April 2014 as being tied for the warmest April on record. This is the first time Earth has experienced back-to-back warmest months on record since a four-month stretch during March, April, May, and June 2010. Global ocean temperatures during May 2014 tied for the greatest departure from average of any month in recorded history.
