The Rate Of Climate Warming

Has doubled since 1990! Rate has gone from .16°C to .32°C per decade

At this rate the temperature rise = 1.5°C Threshold in 2030!

And 2°C Threshold by 2050!

One Hundred Thousand Years

The last time the Earth was this warm was about 100,000 years ago

What did it look like then

Seas were 20 - 30 feet higher

NYC was under water & so was much of Florida Washington DC & Boston too

The climate warming baked into our system is irreversible from a Sea Level Rise point of view – SLR will go on for hundreds of years

Hurricanes!

Hurricanes

The average number of named storms has risen from 12 to 14 when comparing 1960 -1990 to 1990 - 2020

Average hurricane season - 7 hurricanes and 3 Major Hurricanes 2021 & 2022, 51 storms! NO SEQUEL -Stronger too! Since 1851 - 37 Cat 5 of storms And 141 - Cat 4’s The greatest storms on earth!

Air pollution is killing about 500K per year ++Forest Fires

Carbon particles & pollutants in smoke aggravate chronic heart & lung diseases, asthma, bronchitis, and worsen

diabetes Forest Fire Smoke is taking a big toll – at least 33K per yr. Some fleeing the summer smoke in the Western USA Worldwide – Climate Refugees on the rise 2021 Florida Climate Forecast Conference 30

Sea Levels have already risen 9 inches since 1950

The rate of rise is increasing Some very serious issues will arrive by 2035

THE INTENNSITIFING RISK OF CLIMATE WARMING

How’s this impacting you? Insurance premiums are out of control! Many can’t get insurance i.e., over 250,000 in CA canceled, Florida too! $50B in insured losses due to fire since 2016 40 Climate Disruptions in US in 2020 & 2021 over $1B Each and now Ian $100B+ Cost of Climate Refugees isn’t being calculated BUT… 2021 Florida Climate Forecast Conference 32

Economy

Adapt & Mitigate – The Largest Economic Opportunity Maybe EVER!

To get there… Governments need to get in front and not just react…and soon. Plan, zone, building codes, and move from traditional geography to regional cooperation Private Enterprise will have to implement with lots of funding from goverments and innovate, fund and deliver products and for the CLIMATE ECONOMY Academe – new focus on the Grand Challenge of Climate Warming with tomorrow’s climate workers, focused research and entrepreneurship & science

Natural Catastrophe Losses Rising & Here to Stay

• In 2020 prices Natural Catastrophe losses rose from $71B for 2011-2015 to over $90B for 20162020 an increase of about 27%

• Natural Catastrophes for 2021 are estimated to be over $100B

• So far in 2022 estimates are well over 150B

• During this time property rates have been rapidly increasing last few years after years of slow rising rates

• In addition S&P Global estimates that the insurance industry is under capitalized by 33% 50% for climate change risks

So What does all this mean? • Increased losses, less capacity Increased Costs • Increased focus on risk selection by insurers; riskier exposures harder to find coverage • Drive to Invest in better Infrastructure Decreased Losses and Costs

How much damage will climate change cause?

Economic Summary

• Economic growth outlook: Uncertain, but recent history is most consistent with the low end of expert opinion and IPCC scenarios.

• Climate change outlook: We are probably headed for 2-3 degrees C warming by 2100.

– Not 4-5 degrees (RCP8.5)!

• Economic damages from climate change: Rising risks from economic damage, climate migration, switching costs, and strategic climate feuds

Highly unequal impacts by country, region & economic strata

Amazing economic opportunity if threat is perceived as opportunity.

• Energy agencies have serially underestimated pace of energy transition and drops in renewable prices. Multipliers from building clean infrastructure are unknown, but could be high.

Therefore, transitioning might be better for the economy than we think!

This Isn’t A Problem For Someone Else!

Climate Change Isn’t Coming Its Here, Time To Get Going!

Government is slow and its going to hurt if they don’t speed up

Climate Czar at the highest levels in each government entity

Every project from now on MUST have a Climate Resilience Factor

Bridges and roads, schools, public and new private buildings

Real Estate Developments, retrofitting existing buildings, beachmanagement, evacuation centers, distributed power

Process for all streamlined, optimized for speedy completion

ESG MAY be an important component of the change we need but it’s too vague,easy to manipulate, not based on standardized sound measurement systemswith accountability metrics & post results rewards & consequences.
