Climate change spending is already more than one Manhattan project every year or 7 times DARPA annual budget

The Manhattan Project employed more than 130,000 people and cost nearly US$2 billion (about $26 billion in 2014 dollars). Over 90% of the cost was for building factories and producing the fissile materials, with less than 10% for development and production of the weapons. Research and production took place at more than 30 sites across the United States, the United Kingdom and Canada.

DARPA has around 240 (about 140 technical) directly managing a $3 billion budget. These figures are “on average” since DARPA focuses on short-term (two to four year) projects run by small, purpose-built teams.

DARPA biggest successes were being a major part of developing the internet, Global positioning satellites, Speech translation, stealth planes, and Gallium Arsenide.

From 1989 to 2008 it is conservatively believed that $79 billion was spent by the US government on climate change research, administration, foreign aid, tax breaks and education (public relations).

Up to 2008, the EU Framework 7 programme includes €1.9 billion on direct climate change research. Framework 6 ran to €769 million. If we take all the Annex 1 countries, the sum expended must be well over $100 billion.

The global carbon trading markets are at about $60 billion in 2014.

The Whitehouse report on climate change spending proposes a budget of $21.4 billion.

The President’s 2014 Budget proposes over $21.4 billion for climate change activities. This amount is $1.2 billion , or 5 percent, lower than the 2013 enacted level for climate change programs, activities, and related tax policies.

Just three per cent of Americans consider “the environment” the most important problem, according to the latest Gallup poll. (In Britain, too, people appear to be decreasingly worried about climate change). This surely represents, by some margin, the biggest PR fail in history. A large part of the money spent is on public relations and there are constant messages in the media about climate change. There are also movies and tv shows.

IPCC wants almost a trillion per year to be spent by through 2030 and then to increase spending to over a trillion per year.

Nextbigfuture thinks the spending should go to fight actually proven to be harmful air pollution. This will pay itself with reduced public health and medical costs. Addressing particulate and soot air pollution would also have a faster and cheaper impact on climate than the harder and slower management of carbon dioxide.

This list of US government spending is not for installing solar and wind power except for the energy tax credits that may reduce greenhouse gases.

A 2012 study authored by researchers at the Breakthrough Institute, Brookings Institution, and World Resources Institute estimated that between 2009 and 2014 the federal government will spend $150 billion on clean energy through a combination of direct spending and tax expenditures. Renewable electricity (mainly wind, solar, geothermal, hydro, and tidal energy) will account for the largest share of this expenditure, 32.1%, while spending on liquid biofuels will account for the next largest share, 16.1%.

In 2009, the three largest renewable fuel subsidies were:

Alcohol Credit for Fuel Excise Tax ($11.6 billion)
Renewable Electricity Production Credit ($5.2 billion)
Corn-Based Ethanol ($5.0 billion)

So corn ethanol and the alcohol credit (another ethanol and biofuel credit) were the biggest but were somewhaat deemphasized in 2012.
