How do scientists find evidence of climate change in the past?

Answers

Answer 1

Answer: Then scientists focus on climate from before the past 100-150 years, they use records from physical, chemical and biological materials preserved within the geologic record. Organisms (such as diatoms, forams and coral) can serve as useful climate proxies. Other proxies include ice cores, tree rings, and sediment cores.

Explanation:

Answer 2

Answer:

To get at the data contained in ice cores, they must be melted so that the water from the outside of the core does not touch water from the center of the core

Explanation:

Scientists can also use ice cores to learn about the temperatures for each year. As snow accumulates onto a growing glacier, the temperature of the air imprints onto the water molecules in the ice.

Read the passage from a 1950 speech by Senator Margaret Chase Smith.

I think that it is high time that we remembered that the Constitution . . . speaks not only of the freedom of speech but also of trial by jury instead of trial by accusation. Whether it be a criminal prosecution in court or a character prosecution in the Senate, there is little practical distinction when the life of a person has been ruined.

Based on this excerpt, what can you tell about Smith’s opinion of Senator Joseph McCarthy and his actions?

She did not support McCarthy’s actions and thought they were against the Constitution.
She supported McCarthy’s actions and thought they were appropriate during the Red Scare.
She supported McCarthy’s actions but thought the courts should rule on whether they were constitutional.
She did not support McCarthy’s actions overall but thought some were needed to protect the American people.

In a paragraph, what is his argument and what are the policies for and agaist the plan

Jan. 14, 1790

Alexander Hamilton, the first Secretary of the Treasury, made his long-awaited report on public credit to Congress on Jan.14. The boyish financial whiz – he celebrated his 33rd birthday Jan. 11 – listened as his 51-page report was read aloud to the nation’s solons at Federal Hall, at the intersection of Wall and Broad Streets. The document, dense with complex financial detail, left congressmen speechless.

They won’t stay that way for long. Hamilton’s basic point is simple enough: “States, like individuals, who observe their engagements – “that is, pay their debts – “are respected and trusted.” But two of Hamilton’s ideas about how the United States should pay its debts are sure to be controversial.

Polls and economists call Hamilton’s rst idea Assumption. The U.S. government took on a load of debt during the Revolutionary War. So did each of the 13 states. Some states have paid their debts off; others – notably Massachusetts, lately the scene of Shays’ Rebellion – are still struggling. Hamilton wants the U.S. government to assume all the state debts, and pay them off along with the national debt, to avoid the “collision and confusion” of different repayment schemes.

Hamilton’s second idea is Non-Discrimination. The largest class of creditors is Revolutionary War soldiers and officers, who were paid in certificates, or IOU’s. (Military unhappiness with IOU’s nearly caused a mutiny at Newburgh in 1783.) Over the years, many vets sold their certificates at a discount, in return for ready cash. Should the government discriminate between brave soldiers who hung on to their IOU’s, and shrewd investors who snapped them up? Hamilton says no: fooling with the terms of repayment now would be a “breach of contract.”

Where will the U.S. government’s money come from? According to Sec. Hamilton, from tariffs and from an excise tax on distilled spirits. Investors have been guessing about Hamilton’s intentions for months. New York is buzzing with rumors of ships and coaches full of money, headed for the South and the frontier to buy up the certificates of veterans who are clueless about what is happening in the nation’s capital. Critics will surely latch on to such stories to attack Sec. Hamilton’s program. The man to watch: Rep. James Madison (Virginia) – Sec. Hamilton’s friend and ally during the ght to ratify the Constitution, but now said to be disturbed by both Assumption and NonDiscrimination. At the same time, Sec. Hamilton has powerful allies, none more powerful than his old boss, President George Washington.
