As global warming increases regional surface temperatures, power consumption will increase nonlinearly for air conditioning and refrigeration, as illustrated by the linked article:

Title: "Unprecedented heat in the Southwest shatters energy use records"

https://www.usatoday.com/story/news/nation-now/2017/06/30/unprecedented-heat-southwest-shatters-energy-use-records/440423001/

Extract: "Unprecedented temperatures across the Southwest pushed power companies into uncharted territory last week as they shattered records for electricity use."

But winter demand will drop as winters heat up.  I wonder which will be greater?

Summer heat, at least solar is getting cheap.

I wonder if increased heat in the southern states will cause population levels to drop there and increase in northern states as they become more temperate?  Long term, I think we see migration toward the poles.  Short term we're likely to see fewer snowbirds and see them stay in the southern states fewer weeks.

The balance of heating and cooling depends of course on the length of the corresponding periods, but as such I've beentold by air heatpump installers that one would use three times the energy to cool down a house compared to heating it same amount of degrees...

I wonder if that holds if one is using a modern heat pump for both heating and cooling?  "Three times the energy" could be comparing an average (not so efficient) AC unit and fossil fuel (gas or oil furnace).

Heat pump energy efficiency gain is only for heating and then only for non-extreme cold situations if air source. For cooling it is just an air conditioner after all. If the heat pump is ground source then efficiency is closer to 4 times natural gas energy efficiency and cooling is also much more efficient than air source air conditioners.

Issue lately is right now natural gas is usually more than 4 times less expensive than electricity so energy efficiency doesn't save money.

Air conditioners are heat pumps run in the opposite direction.  They either pump heat in or out, depending on whether we want the inside of the building to be hotter or colder.  Heat pumps have become much more efficient in the last few years.

I suspect we will move to heat pumps with thermal storage.  When electricity is cheap we will heat or cool either an insulated vat of water or the soil close to the building.  Then when we need heat or cold we'll pull from/transfer heat to that stored heat/cold.

G-20 Ambush: Let's stump Trump
If you think President Trump has enemies in Washington, just wait until he gets to the G-20 economic summit later this week in Hamburg. There, world leaders will be lying in wait to ambush the rogue American....

"Friday's meeting of world leaders in Germany is already being billed as the "G19" summit—U.S. exiled under Trump."

G20 to focus on climate change despite Trump’s resistance
Group of 20 leaders, including Prime Minister Justin Trudeau, are expected to endorse new action to battle climate change at their summit in Germany this week over the opposition of U.S. President Donald Trump.

As chair of this year's summit, German Chancellor Angela Merkel has made it clear that she intends to focus on furthering the goals of the Paris climate accord, while Mr. Trump has set in motion the United States' withdrawal from the treaty.

Over the past several weeks, Mr. Trudeau has spoken to several G20 leaders – including Ms. Merkel, British Prime Minister Theresa May, Chinese President Xi Jinping and Indian Prime Minister Narendra Modi. After each call, the Prime Minister's Office in Ottawa released a "read-out," in every case reporting that Mr. Trudeau and the other leader had reaffirmed their commitment to the international effort to fight climate change.

He also spoke to Mr. Trump, but his office gave no indication that climate change was discussed.

As was the case at the recent G7 summit in Italy, the G20 now faces the choice of allowing Mr. Trump to veto any wording that would support the Paris accord, or making that endorsement without him.

"The outcome clearly matters," said Andrew Light, a senior fellow at the World Resources Institute in Washington and former State Department official.

"It matters because one of the biggest emitters in the world and one of the parties that was pushing hardest and longest to achieve the Paris accord has announced its intention to withdraw. So in the face of that, you absolutely need a statement of solidarity – a G19 or as close as you can get to a G19 commitment on climate change."

I had a beer once with Andrew Light--very bright guy!

Why Trump Pulling Out of the Paris Agreement Led to a Stronger Global Climate Change Plan
As President Trump mulled pulling the U.S. out of the Paris Agreement on climate change earlier this year, supporters of bold policies to address global warming around the world feared that the U.S. withdrawal would hinder action on the issue.

But on Saturday, with the exception of Trump, the leaders of the world's largest economies gathered at the G20 reaffirmed their commitment to fostering clean energy development and implementing the Paris Agreement on climate change. Instead of attracting other laggards, Trump's decision freed the rest of the world to issue a strong Climate and Energy Action Plan for Growth Saturday that aims to address global warming — and measures aimed at appeasing Trump were mostly absent.

"In the end, the negotiations on climate reflect dissent — all against the United States of America," German Chancellor Angela Merkel told reporters following the summit, according to a Reuters report.

This is something I've wondered about for some time, whether the US was doing more to hold back the Paris accord from within, than it can now that it's on the outside. Trade sanctions based on carbon usage might now be a possibility!

Morgan Stanley analysis:

“By our forecasts, in most cases favorable renewables economics rather than government policy will be the primary driver of changes to utilities’ carbon emissions levels....  For example, notwithstanding president Trump’s stated intention to withdraw the US from the Paris climate accord, we expect the US to exceed the Paris commitment of a 26-28% reduction in its 2005-level carbon emissions by 2020.”

Renewable energy is becoming so cheap the US will meet Paris commitments even if Trump withdraws

Colorado signs on to U.S. Climate Alliance, joining states committed to exceeding Trump’s rejected Paris climate targets
- Gov. Hickenlooper orders statewide greenhouse gas emissions cut
MORRISON – Colorado on Tuesday joined the growing number of states and cities committed to meeting or exceeding the greenhouse gas reduction targets set in the international Paris climate treaty that President Donald Trump rejects.

Gov. John Hickenlooper issued an executive order declaring a goal of cutting statewide greenhouse gas emissions by at least 26 percent below 2005 levels by 2025. Hickenlooper also announced Colorado will sign on to the U.S. Climate Alliance of businesses and states working to capitalize on renewable energy.

Colorado will accelerate work toward climate goals “regardless of what the federal government decides to do,” Hickenlooper said before signing the order at the Red Rocks park overlooking metro Denver.

California Legislature extends state's cap-and-trade program in rare bipartisan effort to address climate change
California lawmakers voted Monday evening to extend the state’s premiere program on climate change, a victory for Gov. Jerry Brown that included unprecedented Republican support for fighting global warming.

In a break with party leaders and activists in California and Washington, eight Republicans joined with Democrats to continue the cap-and-trade program, which requires companies to buy permits to release greenhouse gases into the atmosphere.

The legislation would keep the 5-year-old program operating until 2030, providing a key tool for meeting the state’s ambitious goal for slashing emissions. Cap and trade also generates important revenue for building the bullet train from Los Angeles to San Francisco, another priority for the governor....
