former ocean science professor now VP @AlaskaRenew on a mission to deploy renewable energy at scale

Do air source heat pumps make sense in really cold climates like Interior #Alaska?

I estimate that the average home owner could save about $1,400 per year in heating costs by adding a heat pump!

@saraffas Ask for hahnenwasser ;)

@duncancampbell Check out this study: https://t.co/piuu1ixnbU

@duncanmgibb @janrosenow @joesmyth Recent lab based study from CCHRC/NREL with a useful tool for calculating COP at different loads and temps https://t.co/b0qBL4qtcZ

@SeanatGreenwire Are these emissions standards or local air quality standards?

[Jesse D. Jenkins @JesseJenkins]

After passage of the Inflation Reduction Act, the environmental movement needs to focus on building wind & solar power and transmission at record pace, writes @NRDC. Amen. https://t.co/vwErhFeEEo

The IRA is a historic climate bill, but to get passed Sen. Manchin demanded a mandatory oil lease in Alaska's Cook Inlet. If developed, experts calculate the risk of a major spill at 1 in 3. Compelling piece by @LoisParshley asks: Development at what cost?

Delta Junction is open for EV users! Mr. Hensley performed the inaugural test charging session at -21°F with “[the] Wind chill is brutal here”.
Step 1 of opening the Richardson Highway!

[ReCharge Alaska @ReChargeAlaska]

Great news, Glennallen is operational! Step 2 is complete to opening the Richardson Highway. -36°F and the Bolt is doing good and taking the charge.

Despite being entirely self-taught in machine learning and all but basic stats, I have somehow become a go-to reviewer of "machine learning applied to climate" type papers. Having reviewed several in the last few months, here's some (unsolicited) advice to authors:

@AlaskaWx @ScottDuncanWX @WorldClimateSvc @CopernicusECMWF I noticed this a month ago too, but it was my first time looking for it, so I assumed it was typical

You know those days when you spend an entire work day writing and rewriting a single very important email. Here's to hoping it was all on point and worthwhile!

[Andrew McDonnell @AMPMcDonnell]

@siegristj Hope you all get well soon. We've been through several waves of sick too.

@AlaskaWx @Climatologist49 Nice job on the wishcasting! https://t.co/i71J2KJMDg

My kids think I'm going boating and they insist to come along. Hoping they are not disappointed when they learn about voting instead

The Arctic Ocean is changing due to Ocean Acidification, warming, etc. @claeha @James1Orr

[Alaska Renewables @AlaskaRenew]

Alaska Renewables began its meteorological campaign near Little Mount Susitna by installing a 60m tall meteorological tower in October. The data collected will enable us to assess the wind resource and accurately estimate energy production from the prospective wind farm.

@drago_laetitia Haha, nice. I think I see a chaetognath hiding in there
