Parts of the state have had their earliest 70-degree readings on record. Klawock, a town in southeastern Alaska, reached 70 F on March 19 — the earliest any spot in the state has hit that high.

More records are expected to be broken this weekend, with temperatures soaring as much as 50 degrees above normal in the fastest-warming state…

Nearly 75 percent of coal-fired power plants in the United States generate electricity that is more expensive than local wind and solar energy resources, according to a new report. Wind power, in particular, can at times provide electricity at half the cost of coal, the report found…

Every year, the World Economic Forum asks some 1,000 decision-makers from the public sector, business, academia and civil society across the globe to assess the risks facing the world over the decade to come.

Since 2012, water crisis has consistently been ranked as one of the threats with the highest potential impact as well as likelihood. The top scores on both impact and likelihood are perceived to be: extreme weather events; failure of climate change mitigation and adaptation; and natural disasters.

Of the 1,000 most severe disasters that have occurred since 1990, water-related disasters accounted for 90 per cent. With extreme water and weather events increasing in both frequency and severity in the wake of climate change, floods and droughts are set to strike harder and more often in the years to come…

Splitting water into hydrogen and oxygen presents an alternative to fossil fuels, but purified water is a precious resource.

Stanford researchers have devised a way to generate hydrogen fuel using solar power, electrodes and seawater – Earth’s most abundant source – for chemical energy…

Our oceans broke heat records in 2018 and the consequences are catastrophic

Last year was the hottest ever measured, continuing an upward trend that is a direct result of manmade greenhouse gas emissions.

The key to the measurements is the oceans. Oceans absorb more than 90% of the heat that results from greenhouse gases, so if you want to measure global warming you really have to measure ocean warming…

To Hold Warming to 1.5 Degrees, Study Says Nations Must Stop Building New Fossil Fuel Infrastructure Immediately; Yale E360 (01-15-2019)
If nations commit immediately not to replace fossil fuel infrastructure as it reaches the end of its expected lifetime, the world would have a 64 percent chance of keeping global warming below 1.5 degrees Celsius, according to a new study…

A new study confirms the urgency to tackle climate change. While it’s known that extreme weather events can affect the year-to-year variability in carbon uptake. this study is the first to actually quantify the effects through the 21st century…

Why don’t U.S. nuclear regulators acknowledge the dangers of climate change?

When America’s fleet of nuclear reactors was designed some four-plus decades ago, few people had ever heard the phrase “climate change.” Today, the global threats of worsening weather patterns and natural disasters are well recognized, commanding concern and responses across the board. Except, apparently, at the U.S. Nuclear Regulatory Commission…

Between 2014 and 2016, parts of the eastern Pacific Ocean warmed as much as 7 degrees Fahrenheit above average during what has been characterized as the worst marine heatwave on record. During the event, scientists began discovering a record number of tropical sea species along the northern California and Oregon coasts, more than 700 miles north of their usual range…

Fatal horizon, driven by acidification, closes in on marine organisms in Southern Ocean

Marine microorganisms in the Southern Ocean may find themselves in a deadly vise grip by century’s end as ocean acidification creates a shallower horizon for life.

The modeling study, published today in the journal Nature Climate Change, forecasts that at current carbon dioxide emission rates, the depth at which some shelled organisms can survive will shrink from an average of 1,000 meters today to just 83 meters by the year 2100, a drastic reduction in viable habitat.

The steep drop, which could happen suddenly over a period as short as one year in localized areas, could impact marine food webs significantly and lead to cascading changes across ocean ecosystems, including disruptions of vital global fisheries…
