Claim: Coastal lake sediments along the Gulf of Mexico shoreline from 1,000 to 2,000 years ago suggest more frequent and intense hurricanes than occur today.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: In the Gulf of Mexico, catastrophic hurricane strikes at given locations occur once about every 350 years in the last 3,800 years or about 0.48%-0.39% annual frequency at any given site, with a recurrence rate of 300 years or 0.33% annual probability at sites in the Caribbean and Gulf of Mexico; category 3 or more storms occur at a rate of 3.9 - 0.1 category 3 or more storms per century in the northern Gulf of Mexico.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: In the past, tropical cyclones were far more frequent in the Great Barrier Reef and the northern Gulf of Mexico than today; in Apalachee Bay, strong storms occur every 40 years, not every 400 years as documented historically.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The Gulf of Mexico saw increased activity between 3,800 - 1,000 years ago with a fivefold increase of category 4-5 hurricane activity, and activity at St. Catherines Island and Wassaw Island was also higher between 2,000 and 1,100 years ago.

Passage: Few major hurricanes struck the Gulf coast during 3000–1400 BC and again during the most recent millennium.

Passage: Paleotempestology uses these same records to help determine hurricane frequency over millennia.

Passage: Based on sea-level data from the Mississippi Delta, the end of the Lake Agassiz–Ojibway (LAO) drainage occurred at 8.31 to 8.18 ka and ranges from 0.8 to 2.2 m. The sea-level data from the Rhine–Meuse Delta indicate a of near-instantaneous rise at 8.54 to 8.2 ka, in addition to 'normal' post-glacial sea-level rise.

Passage: Seas, oceans, and lakes accumulate sediment over time.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: According to statistical hurricane research between 1886 and 1996 by the North Carolina State Climatology Office, a tropical cyclone makes landfall along the coastline about once every four years.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In the North Atlantic, sediments accumulated since the end of the last ice age, nearly 12,000 years ago, show regular increases in the amount of coarse sediment grains deposited from icebergs melting in the now open ocean, indicating a series of 1–2 °C (2–4 °F) cooling events recurring every 1,500 years or so.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: However, palaeotempestological research allows reconstruction of pre-historic hurricane activity trends on timescales of centuries to millennia.
