Senate Budget Committee Hearing Today | Climate Etc. (judithcurry.com)

Insurance markets are influenced by our perceptions of climate risk. Referring to climate change as a “crisis” is at odds with professional judgments of climate risk.
The so-called “climate crisis” isn’t what it used to be. In 2013 in the IPCC Fifth Assessment Report, the extreme emissions scenario RCP8.5 was regarded as a business-as-usual scenario. With expected warming of 4 to 5 degrees Centigrade by 2100. Now, there is general acceptance that this extreme scenario is implausible. The value of baseline warming currently used by the UN Conference of Parties has been reduced by half, to 2.5 degrees by 2100. This is an additional 1.3 degrees above current temperatures.

It’s difficult to overstate the importance of the shift in expectations for extreme weather events that is associated with rejection of this extreme scenario. Rejecting this extreme scenario has rendered obsolete much of the climate impacts literature and assessments of the past decade, that have focused on this scenario.

BERLIN (AP) — Voters in Berlin go to the polls this weekend to decide on a proposal that would force the city government to drastically ramp up the German capital’s climate goals.

Sunday’s referendum, which has attracted considerable financial support from U.S.-based philanthropists, calls for Berlin to become climate neutral by 2030, meaning that within less than eight years the city would not be allowed to contribute further to global warming. An existing law sets the deadline for achieving that goal at 2045, which is also Germany’s national target.

The center-right Christian Democratic Union, which won a recent local election in the capital and is likely to lead its new government, opposes the earlier target but would be bound to implement it if the referendum passes.

Jessamine Davis, a spokesperson for the grassroots group that initiated the vote, said Berlin’s current target isn’t in line with the 2015 Paris climate accord, which aims to cap global warming at 1.5 degrees Celsius (2.7 Fahrenheit) compared with the pre-industrial average.

Climate goals, yay.  Paper not worth paper.  What happens if they pass these climate goals and then don't meet them?

Hand wrining?  Harsh language?

There are different flavors of doomers. Some are middle-aged and have been influenced by outspoken scientists — like retired ecologist Guy McPherson — who claim that human extinction, or at least the breakdown of society, is imminent. (“I can’t imagine that there will be a human left on the Earth in 10 years,” McPherson has said.) These doomers drift toward conspiracy theories, sometimes claiming that the Intergovernmental Panel on Climate Change is downplaying the seriousness of the issue.


That piece is "funny", to me, another completely unrealistic assessment and label with no purpose.

EU was set to ban internal combustion engine cars. Then Germany suddenly changed its mind | CNN Business

Scientists say reducing planet-heating pollution [color=var(--theme-paragraph__link-color)]is non-negotiable[/url] if the world is to limit global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels and avoid a key tipping point beyond which extreme flooding, droughts and wildfires will likely become much more frequent.[/font][/size][/color]

Despite such warnings and the pledges made in the Paris Agreement to tackle climate change, global emissions have continued to rise, barring a dip in 2020.

Talks are continuing to persuade Germany to support the law. In its current draft form, the law would allow cars running on e-fuels to be sold after 2035, but only if they were fitted with technology preventing them from running on gasoline or diesel.

The 1.5°C goal is not achievable, simply put, no matter what.  And to claim exceeding that arbitrary goal means MUCH more frequent adverse weather events is simply inane and stupid.

what percent of the total co2 in the air is man made

The typical baseline figure I see is 280 ppm, and we're at 410 ppm now (0.04%), so about a third.  That 280 ppm is responsible for warming the planet about 59°F, or so folks say.

So, it's a fairly large influencer.  Water vapor is also a factor, a confounding one at that.  This is partially why the models get so complex.
