1. Efek Rumah Kaca
Efek rumah kaca adalah proses penghangatan bumi karena adanya penyerapan sinar infra merah.Tanpa adanya efek ini suhu bumi akan turun sekitar 30° C.Sinar yang datang ke bumi sebanya 30 % dipantulkan dan sisanya digunakan untuk menghangatkan daratan,lautan dan atmosfer.efek rumah kaca terjadi karena bumi relatif transparan terhadap sinar tampak,namun sangat menyerap sinar infra merah sehingga bumi akan menghangat karena adanya penyerapan energi tersebut. Efek rumah kaca juga merupakan efek alamiah untuk menjaga temperature permukaan Bumi pada suhu normal sekitar 30°C,atau kalau tidak ada ,maka tentu saja tidak akan ada kehidupan dimuka Bumi ini.
Pemanasan global yaitu bertambah panasnya atmosfer Bumi serta samudra selama beberapa dekade terakhir.Menurut penelitian suhu bumidi ketahui meningkat 0,6 kurang lebih 0,2 °C selama 20 Abad terakhir.
(Nur Farida 2009 :53) Mengatakan, bahwa pemanasan global yaitu disebut juga global warming ,istilah tersebut digunakan untuk menggambarkan fenomena peningkatan suhu rata – rata atmosfer Bumi.Peningkatan suhu Bumi ini dianggap akan secara permanen mengubah iklim Bumi selamanya.

Obama Finds a Bolder Voice on Race Issues
As he reflected on the festering wounds deepened by race and grievance that have been on painful display in America’s cities lately, President Obama on Monday found himself thinking about a young man he had just met named Malachi.
A few minutes before, in a closed-door round-table discussion at Lehman College in the Bronx, Mr. Obama had asked a group of black and Hispanic students from disadvantaged backgrounds what could be done to help them reach their goals. Several talked about counseling and guidance programs.
“Malachi, he just talked about — we should talk about love,” Mr. Obama told a crowd afterward, drifting away from his prepared remarks. “Because Malachi and I shared the fact that our dad wasn’t around and that sometimes we wondered why he wasn’t around and what had happened. But really, that’s what this comes down to is: Do we love these kids?”
Many presidents have governed during times of racial tension, but Mr. Obama is the first to see in the mirror a face that looks like those on the other side of history’s ledger. While his first term was consumed with the economy, war and health care, his second keeps coming back to the societal divide that was not bridged by his election. A president who eschewed focusing on race now seems to have found his voice again as he thinks about how to use his remaining time in office and beyond.
In the aftermath of racially charged unrest in places like Baltimore, Ferguson, Mo., and New York, Mr. Obama came to the Bronx on Monday for the announcement of a new nonprofit organization that is being spun off from his White House initiative called My Brother’s Keeper. Staked by more than $80 million in commitments from corporations and other donors, the new group, My Brother’s Keeper Alliance, will in effect provide the nucleus for Mr. Obama’s post-presidency, which will begin in January 2017.
“This will remain a mission for me and for Michelle not just for the rest of my presidency but for the rest of my life,” Mr. Obama said. “And the reason is simple,” he added. Referring to some of the youths he had just met, he said: “We see ourselves in these young men. I grew up without a dad. I grew up lost sometimes and adrift, not having a sense of a clear path. The only difference between me and a lot of other young men in this neighborhood and all across the country is that I grew up in an environment that was a little more forgiving.”
Organizers said the new alliance already had financial pledges from companies like American Express, Deloitte, Discovery Communications and News Corporation. The money will be used to help companies address obstacles facing young black and Hispanic men, provide grants to programs for disadvantaged youths, and help communities aid their populations.
Joe Echevarria, a former chief executive of Deloitte, the accounting and consulting firm, will lead the alliance, and among those on its leadership team or advisory group are executives at PepsiCo, News Corporation, Sprint, BET and Prudential Group Insurance; former Secretary of State Colin L. Powell; Senator Cory Booker, Democrat of New Jersey; former Attorney General Eric H. Holder Jr.; the music star John Legend; the retired athletes Alonzo Mourning, Jerome Bettis and Shaquille O’Neal; and the mayors of Indianapolis, Sacramento and Philadelphia.
The alliance, while nominally independent of the White House, may face some of the same questions confronting former Secretary of State Hillary Rodham Clinton as she begins another presidential campaign. Some of those donating to the alliance may have interests in government action, and skeptics may wonder whether they are trying to curry favor with the president by contributing.
“The Obama administration will have no role in deciding how donations are screened and what criteria they’ll set at the alliance for donor policies, because it’s an entirely separate entity,” Josh Earnest, the White House press secretary, told reporters on Air Force One en route to New York. But he added, “I’m confident that the members of the board are well aware of the president’s commitment to transparency.”
The alliance was in the works before the disturbances last week after the death of Freddie Gray, the black man who suffered fatal injuries while in police custody in Baltimore, but it reflected the evolution of Mr. Obama’s presidency. For him, in a way, it is coming back to issues that animated him as a young community organizer and politician. It was his own struggle with race and identity, captured in his youthful memoir, “Dreams From My Father,” that stood him apart from other presidential aspirants.
But that was a side of him that he kept largely to himself through the first years of his presidency while he focused on other priorities like turning the economy around, expanding government-subsidized health care and avoiding electoral land mines en route to re-election.
After securing a second term, Mr. Obama appeared more emboldened. Just a month after his 2013 inauguration, he talked passionately about opportunity and race with a group of teenage boys in Chicago, a moment aides point to as perhaps the first time he had spoken about these issues in such a personal, powerful way as president. A few months later, he publicly lamented the death of Trayvon Martin, a black Florida teenager, saying that “could have been me 35 years ago.”
That case, along with public ruptures of anger over police shootings in Ferguson and elsewhere, have pushed the issue of race and law enforcement onto the public agenda. Aides said they imagined that with his presidency in its final stages, Mr. Obama might be thinking more about what comes next and causes he can advance as a private citizen.
That is not to say that his public discussion of these issues has been universally welcomed. Some conservatives said he had made matters worse by seeming in their view to blame police officers in some of the disputed cases.
“President Obama, when he was elected, could have been a unifying leader,” Senator Ted Cruz of Texas, a Republican candidate for president, said at a forum last week. “He has made decisions that I think have inflamed racial tensions.”
On the other side of the ideological spectrum, some liberal African-American activists have complained that Mr. Obama has not done enough to help downtrodden communities. While he is speaking out more, these critics argue, he has hardly used the power of the presidency to make the sort of radical change they say is necessary.
The line Mr. Obama has tried to straddle has been a serrated one. He condemns police brutality as he defends most officers as honorable. He condemns “criminals and thugs” who looted in Baltimore while expressing empathy with those trapped in a cycle of poverty and hopelessness.
In the Bronx on Monday, Mr. Obama bemoaned the death of Brian Moore, a plainclothes New York police officer who had died earlier in the day after being shot in the head Saturday on a Queens street. Most police officers are “good and honest and fair and care deeply about their communities,” even as they put their lives on the line, Mr. Obama said.
“Which is why in addressing the issues in Baltimore or Ferguson or New York, the point I made was that if we’re just looking at policing, we’re looking at it too narrowly,” he added. “If we ask the police to simply contain and control problems that we ourselves have been unwilling to invest and solve, that’s not fair to the communities, it’s not fair to the police.”
Moreover, if society writes off some people, he said, “that’s not the kind of country I want to live in; that’s not what America is about.”
His message to young men like Malachi Hernandez, who attends Boston Latin Academy in Massachusetts, is not to give up.
“I want you to know you matter,” he said. “You matter to us.”
Negative View of U.S. Race Relations Grows, Poll Finds
Public perceptions of race relations in America have grown substantially more negative in the aftermath of the death of a young black man who was injured while in police custody in Baltimore and the subsequent unrest, far eclipsing the sentiment recorded in the wake of turmoil in Ferguson, Mo., last summer.
The poll findings highlight the challenges for local leaders and police officials in trying to maintain order while sustaining faith in the criminal justice system in a racially polarized nation.
Sixty-one percent of Americans now say race relations in this country are generally bad. That figure is up sharply from 44 percent after the fatal police shooting of Michael Brown and the unrest that followed in Ferguson in August, and 43 percent in December. In a CBS News poll just two months ago, 38 percent said race relations were generally bad. Current views are by far the worst of Barack Obama’s presidency.
The negative sentiment is echoed by broad majorities of blacks and whites alike, a stark change from earlier this year, when 58 percent of blacks thought race relations were bad, but just 35 percent of whites agreed. In August, 48 percent of blacks and 41 percent of whites said they felt that way.
Looking ahead, 44 percent of Americans think race relations are worsening, up from 36 percent in December. Forty-one percent of blacks and 46 percent of whites think so. Pessimism among whites has increased 10 points since December.
The poll finds that profound racial divisions in views of how the police use deadly force remain. Blacks are more than twice as likely to say police in most communities are more apt to use deadly force against a black person — 79 percent of blacks say so compared with 37 percent of whites. A slim majority of whites say race is not a factor in a police officer’s decision to use deadly force.
Overall, 44 percent of Americans say deadly force is more likely to be used against a black person, up from 37 percent in August and 40 percent in December.
Blacks also remain far more likely than whites to say they feel mostly anxious about the police in their community. Forty-two percent say so, while 51 percent feel mostly safe. Among whites, 8 in 10 feel mostly safe.
One proposal to address the matter — having on-duty police officers wear body cameras — receives overwhelming support. More than 9 in 10 whites and blacks alike favor it.
Asked specifically about the situation in Baltimore, most Americans expressed at least some confidence that the investigation by local authorities would be conducted fairly. But while nearly two-thirds of whites think so, fewer than half of blacks agree. Still, more blacks are confident now than were in August regarding the investigation in Ferguson. On Friday, six members of the police force involved in the arrest of Mr. Gray were charged with serious offenses, including manslaughter. The poll was conducted Thursday through Sunday; results from before charges were announced are similar to those from after.
Reaction to the recent turmoil in Baltimore, however, is similar among blacks and whites. Most Americans, 61 percent, say the unrest after Mr. Gray’s death was not justified. That includes 64 percent of whites and 57 percent of blacks.
The nationwide poll was conducted from April 30 to May 3 on landlines and cellphones with 1,027 adults, including 793 whites and 128 blacks. The margin of sampling error is plus or minus three percentage points for all adults, four percentage points for whites and nine percentage points for blacks. See the full poll here.
